Inside UP USB connector for better connection when make reflash

[x-land]

I put USB connector inside and the ribbon is solder direct on USB PCB. In next days I try make a little tutorial for this modification. It's first try and the USB connector isn't in center :D.



http://www.video-games.ro/photo/psp_thread/UPusb.jpg

HERE (http://www.video-games.ro/tutorial/tutorial.htm) can find 3 tutorials:

1 Tutorial with case modification without components
2 Tutorial with 2 transistors and 4 resistors. With this can use PSP USB connector.
3 Tutorial with cable modification without other components. Use PSP USB connector.

[DaWaN]

Wow that looks slick man!!

[scroller]

Because me and my UP customers have problem with connector and can't reflash the UP in good condition I try find a solution. I put USB connector inside and the ribbon is solder direct on USB PCB. In next days I try make a little tutorial for this modification. It's first try and the USB connector isn't in center :D.very well done

[whackawookie]

wow, very nice. Thats one clean looking job

[babb_z]

Definately a mod to use.

Too right, i want to do mine lol.

[x-land]

I make the tutorial (is in my first post). Enjoy it ;). (sorry for bad english :D)

[Squirrel61]

Good job man! I'm gonne try the mod too!

[swisstony123]

superb stuff looks very good!!:D

[duncans_pumpkin]

looks pritty good although it could look even better i still think i prefer 0okms method on his module though. ie. use the psp's own usb socket.

.:EDIT:. I wonder if scroller could look into doing this as i would prefer this on my psp.

Scoller offered me to do mine he says it hasnt been tested and could cause problems. HAS THIS BEEN DONE SUCESSFULLY?!

[duncans_pumpkin]

well i guess X-land managed it succesfully

[SoCalSRH]

awesome. thanks for the tut x-land. i'm gonna give this a go after i get off work.

Nothing went wrong?! It works? If so IM NEXT lol!

EDIT: I ment the method to use the factory usb connector.

.:EDIT:. I wonder if scroller could look into doing this as i would prefer this on my psp.Actually, 0okm's method does not allow true programming of the modchip flash via PSP's built-in USB port; what he means is that you can transfer a PSP executable onto your memory stick via USB then load that executable from VSH which will program the modchip flash - VERY misleading if you ask me! It requires that your PSP already has 1.0/1.50 firmware installed so you can execute the kernel mode ELF to do the programming which makes it a bit pointless.

not this i meant direct to the internal usb connector i would imagine that this would work by just taking the 2 data lines and power from the usb and adding the resistors as the UP is already grounded and so is the psps usb so you would not need the ground connection from the UP's fpc cable.

im doing a full fpc bypass so will test this and if it works it should as the usb is only active when the xmb usb option is selected and hopefully the UP is only active when put in programming mode this will save everyone doing this mod and cutting up the casing

xlands mod will work 100% you misunderstood what i was talking about the above should clear it up.

First that I want try but I don't have time and I follow easy way for resolve the problem. With some attention I think work and bypass but maybe is need and other components for make signal difference when come in same port. So, tomorrow, if I have time, i study and this part, and I wait news from scroller.

For who want know my mod work 100%. Can see that and in tutorial because isn't big modification. Now I think is better if you wait for know if it's possible use PSP USB for programming UP.

Indeed this would 100% work with dip switch to turn of the on board usb and visa versa.

but if they can live in harmony without the dip switch all the better.

If don't work without switch we can make a little one with one microcontroller, and when is pressed left, for programming mod, switch connector for modchip transfer, else work for PSP transfer. We see, maybe work without any major changes.

agreed a 12c508 would do the job or a flash based atmel tiny.

[x-land]

I think the UP have Rx-Tx transfer open all time. Why? because when we open in normal mod PSP and from UP aplication try connect we have message: the UP isn't in programming mode. That mean the transfer work and with UP in normal mode. When we try transfer data with PSP USB connection that data go and to UP, and UP response. So, I think can't block the data for don't go to UP. In other way why the UP team don't make they that connection because I don't think they chose ribbon solution first and don't study direct connection. I don't think we can make the difference for what transfer we want use.
Tomorrow I open PSP and I try find exactly how work each transfer but in this case (if have both data in same time) I think don't work that mod.

so its always listening shame shouldnt be hard to knock that out of the equation with a small modification and use the wireless lan switch to turn on the UP usb connection in its off position :) but that would leave the original onboard usb working on flashing mode again this might cause problems.

[duncans_pumpkin]

cool it would be good if u got that all working.

Ill be poping over to scollers this week if he agrees i may allow ihm to test it on my psp...

So has anyone tried it yet? Looks like a much safer option in the long run!!

Good news: work transfer with PSP USB and for UP.
Bad news: it's little hard for make this mod.

This is last mod with microcontroller 16f630. Don't look at design, just I finish my test :D.


http://www.video-games.ro/photo/psp_thread/picusb.jpg

Yes.....work well......

Microcontroller work when you put USB connector (for microsecundes and after that is in standby). When want make reflash must press "up" (d-pad) when put USB connector for turn on UP USB and turn off mainboard USB. If isn't pressed PSP work in original state (with mainboard USB on and UP USB off).
My first mod is simple.
This is for who have microcontroller programmer and good skill in soldering.
I come back with this tut and with hex code for 16f630.

damn dude. you're a genius. nice work. that is way beyond my skill level tho. u should sell the whole 'aftermarket' kit to other mod shops. i'd pay for that mod by itself at this point. not being able to flash my u.p. via usb sucks.

[duncans_pumpkin]

looking good cant wait untill uve got it working like a charm.

[Badxil]

It's really great work :)
I will use this mod as soon as you release it

Where can you get hold of a microcontroller programmer?!?!:confused:
Looks like a really good mod you should seriously consider offering it to UP as a redesign!

To scroller:- sorry dude Pm box full have some new news for ye!!!!

[x-land]

I make new mod with 2 transistor and 4 resistor. This is simple and don't need microcontroller and keyboard press for change USB ports. When is in programming mode work UP USB and if isn't work PSP USB.
IF UP team want this can be done direct on UP mainboard and we escape have this problem.
I use one signal from Actel. They can out other signal and make this mod with changes ribbon design.

Now you have 3 mods for use in perfect condition USB transfer. All work very good.
I don't have much time but soon I post and last two tutorials.

[Lodis]

This is all extremely cool and it makes me glad that I have only just sent my Modchip to be done. I am hoping to get the Onboard USB solution implemented on my one though, probably with a switch to select between Memory stick USB access and Modchip access. Having this done on my White Psp (1.5 firmware) should be very cool and since I use a Card Reader 90% of the time it will be left on Modchip access. Oh I am also getting this Dpad fix done http://tinyurl.com/8vjcf (I play alot of fighting games and my Psp Dpad is useless at diagonals / Fireballs, Dragonpunches etc).

[x-land]

I put in my first post and last tutorial. Now missing tutorial with microcontroller. I don't know when and if I make and this.
If UP team can find a little inverter he can make a good job direct on UP mainboard. But that mean redesign mainboard. I can't find here small inversor. Is only DIP format and......
If you have question please contact me here.

EDIT: Sorry for remove last tutorial but I find e little inverter and tomorrow I make new tut :D. Don't make last mod if you download them. I'm back with some very nice soon. That is last time and best solution for this mod.

Could you put it back up? It is impossible to find specialty parts like inverters without ordering and paying an arm and a leg for shipping - would probably be much simpler for most "end users" with the other parts as they'd probably be more readily available at a couple of local stores...

Nice work x-land ;) it just kills me that for a $100 chip, they could have done this type of thing "right" all on their own when designing (I mean, programming mode already takes over the whole PSP, why not just use the built in connector?). Unfortuately (Platinum? lol) it's just giving them more "food" to release a revised/pro chip at a probably higher price with other peoples ideas added instead of other bigger improvements :(

[Squirrel61]

Awesome work X-Land! I'm eagerly awaiting the tutorials!

Can you please attach the 2-transistor solution again? I'm not sure if it's possible for me to find the inverter so I might opt for the transistor solution.

[x-land]

OK. It's uploaded again. You should try first if can find SMD inverter, 74hc04 or 05 or other, work and with NAND or NOR logic gates, important is find SMD format for can place on UP mainboard and must work at 5V and input open > 2V. It's very simple with inverter. I don't verify (mod with inverter) but mod with transistors it's a little inverter with 2 gates.

I don't know if UP team can hear about this mod (and if want use them) but I want have a solution for this problem (my customers broke they ribbon when try programming). So, I let you know what i find for can repair poor ribbon.
I see UP have more problem. I'm lucky man for moment : i have only this problem :)


i wish i had time to play between installing im getting rather busy, going to need a production line soon
Send to me if it's to much work at you :D. Or I come in UK for help you :).

[cory149]

thanks x-land :D You bring to memory a day in class (>10 years ago) when "the suit" tried to teach everyone how almost any circuit/IC can be made with NAND and how gates are basically transistors.

There is one place here I could try that does have SMT components, but I do not beleive it is likely they will have everything... scavenging from other PCB's is usually my best bet to find such things :(

This actually brings this part to mind:

Yes, this is good, you need only 2 resistors and some changes because here is 1 npn and 1 pnp transistor. Must have 5V on pin 3 and on resistor from pnp colector must have gnd. I think you know that :).

EDIT. Now I see input resistor is 22ko. Can't see max and typ hFE (I think is around 350) so you need make all calcul first.

[duncans_pumpkin]

looking good. Wish i understood most of this thread. i mean i know what nand gates and pnp and npn transistors do but some of this is double dutch to me.

lol
Personally, this stuff is making my head ache (its been about 8 years since I have used any of this stuff, and back then SMT wasnt really an option) - but what it means in layman/noob terms:

it shouldnt be all that difficult to wire the UP's USB connector to share the PSP's built in USB connection - meaning no cruddy/bad clip on connector (in fact, Im still somewhat shocked they spent extra to add USB to the FPC and make a custom cable end for it instead of just using 4 extra wires to the PSP's built in USB connector).

I beleve you :). And I'm in same situation. For that first I make mod with microcontroller :D. But because not all users have posibility for programming them I back in time :). That is't if UP team can't make some good for don't exist problem with bad cable.

but this still means making our own mods this is starting to feel so incomplete a let down for such a brilliant peice of equipment which it truly is a nice bit of kit, when installed correctly and fully working.

with the fpc troubles and now bad chips well i personaly feel its the clip connector on the UP that's at fault and the push connector on the usb that's at fault also you can insert the usb addon and it does not test true to the end of the circuit so that rules out the fpc being at fault hence the need sometimes for direct connection.

the next design should include the internal usb mod by xland a shorter fpc its a tad too long tbh a and decent way of connecting the fpc to the UP as cory mentioned i thing a permenent connection with UP already fixed to the fpc would be an ideal solution with xlands usb mod it would be a dream to install it would solve the clip fpc problems alltogether and the usb nasty.

i really think they should stop production and get this sorted.

and i agree bring back the old chunky stuff it outlasts smt stuff ten to one gone are the days when we could snip a resistor off and replace it in a about 30 seconds lol now were down to using tweezers and hair thing tip's instead of the old chunky iron and heat shunts.

[cory149]

Bah, to go far far OT:
Lets just pester 0ookm with our suggestions and use his mod instead... its still in the process of being made so our input would actually be used for community good wrather than to line pockets with a next revision. j/k, but to me it is a valid point - 0ookm is at least out there sharing his research as it goes wrather than just putting up some vague "team X (insert random team name here) makes this soon" type of a deal; I mean, if we had these problems with his unit I'm sure he'd be in here like a dirty shirt helping us figure out the problem.

I was going to write something about "chunky" stuff and how much easier it was to repair, and how SMT resistors even were super-expensive and hard to get when I was taking that stuff in school; then I remembered how many people still use the old fashioned phonographs, and when I was a younger later complained about CDs... it is a sure sign - I now officially (more so) feel old :(

I have to wonder though, if the rumor is true that their programmer is suffering death throws... how many chips are sitting on the sideline waiting to be unleashed after programming to recover costs before they can entertain the thought of a redesign that fixes the actual problems. I think it could easily be a year before that happens (crosses fingers, wishes to be wrong etc).

[x-land]

For moment best mod remain with transistors. At mod with microcontroller or inverter we need and transistor + resistor for necessary current at output. In my picture with microcontroller can see I add this.
BC847 (can find and other transistors with minim 100 mA) transistor have collector current 100 mA and we need this current for device USB-FIFO from UP.
Microcontroller and inverter have only 20-25 mA at output and need transistor for amplified.

[x-land]

I'm back with new nice tutorial (it's in my first post). That I think is best because don't need other components and is simple for release.
Here I use a little modification at UP USB cable. You don't need cut track only one wire in PSP.
When want flash UP use this cable.

[duncans_pumpkin]

i dont really understand ur last tutorial whats the point in it how is it usefull.
ok i get ya it just was a bit strange cause i didnt understand how it worked but i think i know now.

[x-land]

i dont really understand ur last tutorial whats the point in it how is it usefull.

It's very simple. What don't understand?
In this tut don't need components like transistors, resistors, microcontroller or other. Just modify the UP USB cable like in tut and on PSP mainboard solder the ribbon how can see in same tut.
When want flash UP use this modified cable. For memory transfer use a normal cable. I think is verry clear.
I think know at what is usefull first 2 tutorials. And this is for same problem. But other way for release.
If have and other questions im here.

[JordanBlack68]

Hmmm. please tell me exactly what isn't clear. Maybe and my bad english is cause but i try explain you.

Ok what hes saying is you dont need no extras you need a USB Cable and resistors - you use them internally on the USB FPC end and you dont need the external USB board. Get the tut and you will see what he means.

Well done X-LAND.

[scroller]

he is linking up the 5v pin from the UP to an unused pin on the psp mother board which is available in the cable but not connected modifying the cable lets 5v through to the unused pin to activate the UP usb ic.

xland what effect do you get if you use a standard cable ?

[duncans_pumpkin]

it works normally if u use a standard cable.

oh sorry im slow today a standard cable wont activate the UP usb duh :)

[lipa]

The last modification with cable cant be simplier as it is.

But, that means lots of questions from end-users. For example, when you return modified or when you deliver pre-modified PSP to the customer, she or he is usually not able to follow and remember all instructions and information that is delivered to. It's normal, imagine what happens when you pick up your new car. Are you able to remember all what they where told you than?

So it is very likely that the end-user will not notify that has received one special modified cable ONLY for UP USB connection.

I think that second modification is probably most applicable and if possible should be added to the UP v1.1 or 2.0 (who knows) by the UP Team.

[x-land]

And I said second mod is good for put direct on UP mainboard.
But if that don't apear at next version and for who have first UP version last mod is simple and for release and for end-user.

xland: could one not just strip back a bit of the usb shield, swap the connection of the 2 wires (solder and heatshring tubing) and be away (instead of messing with rebuilding the whole end)?

Nice tut, about the only thing missing is which way the cable is facing in the image (though that is indeed easy enough to figure out if you already know where gnd/power is).

not really its a molded plastic surround that needs to be removed to get to the ground sheild anf then to the wires no way around it without cutting and rebuilding you could prolly do it with other cables or try and find a fully wired usb doubtful you could then just snip the wire swap the 5v connection and you know the rest.

[cory149]

If I go halfway between the two USB ends, make a slit in the side carefully (shield and surround) to not cut any of the internal wires, snip 2 of them and reconnect them backwards I think it would work... wouldnt look as nice in the end but sure beats fiddling with plastic mounted solder points/connections... of course, I dont have the cable they give in front of me at the moment too, so it may indeed be simpler to just redo the end too.

[x-land]

Nice tut, about the only thing missing is which way the cable is facing in the image (though that is indeed easy enough to figure out if you already know where gnd/power is).
GND and power at FPC cable or USB cable?
at USB cable it's simple: find USB diagram on net for know wires connection if don't have.
at FPC cable can find GND with multimeter (with UP FPC connected for have gnd). GND is allready connected you only make suplimentar solder (it's better have FPC solder at GND). In finaly can measure what have between GND and USB FPC 5V. If have 0 ohm (it's wrong) that mean you put GND at 5V and must invert USB FPC.

[Squirrel61]

X-land, you already were great. Now you're even GREATER!

Many thanks for all your efforts! I think I'll go for the last mod, unless you find a way to reprogram the UP using the PSP's Wifi :D

:o That would be unsafe! What if the net cuts out, electricity dies or something? Oh wait reflash - god dam i love you UP chip of mine lol.

[Squirrel61]

I went for the third mod. And now I have a problem.

Summary: I didn't have my lucky day. While attempting to solder the 27 ohm resistors from the UP USB board to the PSP's onboard resistors, I think I overheated the onboard resistors, because before the mod they returned 0 ohm and after I finished soldering it was infinite. I think the resistors are used as a fuse, actually. So I decided to remove the onboard resistors (it's 2-in-1 package) and bridge the gaps.

Then, when I tried to remount the 27 ohm resistors, I lost one (it was launched by the wire tension when I wanted to solder it) and couldn't find it back. So I had to search for replacement. I found two 47 ohm resistors in an old cellphone, that returned a parallel value of 24 ohm. I don't think the small difference really matters.

I reassembled everything and went for a testdrive. The UP programming works fine with the modified cable, no problems. So I assume the replacement for the 27 ohm resistor is good enough for transmission purposes.

But when I tried to connect the PSP with the normal cable, my computer reported an "unrecognized USB equipment". Now I'm wondering if the onboard resistors are really resistors (since it's one package with 4 pins, it could be something else too). Or can the connection problem be caused by the 24 ohm resistor, making the UP USB connection a too heavy load on the USB lines?

Edit: I just re-read the tutorial and saw that the onboard resistors aren't 0 ohm but 1.5 ohm. I'll replace the bridge by two resistors and retry it in a few days time.

[scroller]

I went for the third mod. And now I have a problem.

Summary: I didn't have my lucky day. While attempting to solder the 27 ohm resistors from the UP USB board to the PSP's onboard resistors, I think I overheated the onboard resistors, because before the mod they returned 0 ohm and after I finished soldering it was infinite. I think the resistors are used as a fuse, actually. So I decided to remove the onboard resistors (it's 2-in-1 package) and bridge the gaps.

Then, when I tried to remount the 27 ohm resistors, I lost one (it was launched by the wire tension when I wanted to solder it) and couldn't find it back. So I had to search for replacement. I found two 47 ohm resistors in an old cellphone, that returned a parallel value of 24 ohm. I don't think the small difference really matters.

I reassembled everything and went for a testdrive. The UP programming works fine with the modified cable, no problems. So I assume the replacement for the 27 ohm resistor is good enough for transmission purposes.

But when I tried to connect the PSP with the normal cable, my computer reported an "unrecognized USB equipment". Now I'm wondering if the onboard resistors are really resistors (since it's one package with 4 pins, it could be something else too). Or can the connection problem be caused by the 24 ohm resistor, making the UP USB connection a too heavy load on the USB lines?have you checked for connection to the usb board traces maybe you only hooked up the UP usb bypass and not the bridge needed for the psp onboard usb.

I have connection between the first soldering point of both data lines (the point where the UP resistors normally should be soldered) and the connector. I haven't followed the traces yet to measure from an earlier point all the way to the connector.

[Squirrel61]

For the persons who, like me, have their UP already installed and want to make the mod afterwards, and, like me, don't want to remove the mainboard again (risk of damaging the FPC or it's connections), there's an alternative Y point.

I just removed my PSP's front cover, the display keys and the display itself and soldered the Y cable to the second pin from the left on the USB connector. With a needle tip soldering iron, it's possible to reach it from above.

Try if have connection on via points from mainboard. Follow data traces on mainboard and verify from this points.
The mainboard resistors are really resistors (have 1.5 ohm). Can use 1-2 ohm resistors.
24 ohm resistor is good.

Ok, I managed to find some 1.3 ohms resistors on the same cell phone board. I'll solder them, check the data lines and retry.

I used hot glue too. I always use hot glue for this kind of work. It fills, glues and isolates. It is pretty rigid, once cooled and still can be easily removed with a hot air gun. Just be sure not to touch any soldered connection with the tip of the gun, it approaches soldering temp and can desolder a connection. The glue itself never gets near that temp so that's safe for your connections.

[cory149]

thanks cory149. wonderfull stuff that hotglue. I did a search for poxipol and turned up alot of russian looking links.Welcome. I have actually seen Poxipol used in hobbies like hand built RC's (planes/boats) and such where hot glue wont seal as well or hold under vibration, but I figure if you dont know what the stuff is or where to source some locally you'd probably have some hot glue around already (and its likely far cheaper too) ;)

http://www.akapol.com/i_p_poxip.htm

Poxipol® is a two component adhesive, used for multiple applications at home, workshops, in crafts and hobbies.
Poxipol® has exceptional adhesive strength and filling properties.
It can be used to bond as many materials as you can imagine: metal, glass, ceramic, wood, hard plastics, stone, etc.
Equal amounts of each component are mixed to make a non sagging paste that hardens in 10 minutes.
It can be drilled, sanded and painted easily.

I'd look first at the hardware store for a fast curing 2 part epoxy, though you'd probably find poxipol (or someone with a similar product they could recommend) at the "hobby" shop where they sell RC cars/planes and other hobby type things.

[New Age GCS]

You know after scanning this long thread I can't see why so much effort is given to this problem. After about 40 installs I have done I have come across 1-2 that had USB flashing problems. And those were cured by reseating the ribbon connector that couples with the chip. I solved this problem by trimming the sliver of plastic off the end of the ribbon cable. I now do this before the install is even done and for the time being there hasent been any problems. On top of that this USB connection is only really needed once to flash the boot loader. Any smart installer that is installing many of these chips if they came across this problem would just put the chip in a working setup on another PSP and flash the bootloader and transfer it back to the one that is having problems.

[cory149]

New Age GCS: beleive it or not there are more uses for the UP than just Epsilon's bootloader. Not everyone who looks to this thread has other PSP's with UP's in them... some have even received PSP's with the ribbon beyond reasonable repair from "smart" installers who insist the only reason to have an UP is because of epsilons bootloader (which by the way is not entirely incorruptable).

[SoCalSRH]

as cory149 pointed out the bootloader is not 100% bulletproof. for those that can't flash via usb (such as myself) if something happens to the bootloader we're screwed. epsilon is only 1/2 of the use of the u.p. modchip. the most important feature of the chip to me (which i can't even do with the faulty connection) is the ability to entirely rewrite the u.p. nand with different firmware other than the epsilon bios and bootloader. say for example i want to have pure 1.5 fw on the u.p. and 2.8 on the onboard nand, the only way to do that is to flash the pure 1.5 fw through the pc flasher utility via USB. vice versa what if i grow tired of having pure 1.5 fw on the u.p. nand and wanted epsilon on the chip again in the future? i would again be screwed. some aren't seeing the full picture of what the chip is actually intended for. it's not all about 'piracy'. it's about having a secondary flash and the ability to change BOTH firmwares at will...not just one through use of the memstick and hope that nothing happens to corrupt the bootloader on the u.p. nand. the reason i'm so pissed is because the pre-mod i got was not cheap, and to have one of the main functions that i wanted the chip for to begin with not work is a fuckin drag. to make it a little clearer here is an analogy. say for example you buy a brand new huge top of the line hd lcd tv and you can receive 1 hd channel in its full clear resolution but your stuck on 1 channel and can't change the channel. would you be pissed? thought so.

[Squirrel61]

I use poxipol but sure and hot glue it's good.
@Squirrel61: you finished the job? work now?
No, not yet. First, I didn't have enough time to get at it again. Second, the resistors I found weren't 1.3 ohms, they just returned that value as long as they were in-circuit. Now I'm searching for something better, but maybe I have to order them. Usually, circuits of any kind don't hold resistors of that value. Usually they're of higher value, or they are 0 ohm resistors used as a jumper or a fuse.

I'll keep you informed, but I have no doubt that it will be working once I've put everything straight.

Thanks for your support and for the mod itself of course!

[Squirrel61]

You know after scanning this long thread I can't see why so much effort is given to this problem.
I'll tell you. It's all about convenience. I had a working UP installed with a flawlessly working USB connector. But I use to play around with the chip, changing firmwares, upgrading, downgrading, everything. For me it's necessary to reflash the UP sometimes. And then the USB-on-FPC-dangling-from-the-battery-compartment is not a convenient solution. X-Land's third mod is really beautiful and shows UP how it should have been: one connector for two purposes, a special programming cable, everything rigid and unbreakable.

[Squirrel61]

SoCalSRH, if you're not afraid of the soldering, you could try X-Land's third mod. You only have to find two SMT resistors of about the right value. Personally I think any value from 20-35 ohm will do. That way you don't need the USB adapter connector you're missing.

[scroller]

i have to agree and all my installs now contain a varient of xlands mod.

if the bootloader is corrupted and the ribbon itself is damaged which it will break eventually no matter how careful you are it,s a weakness in the design, tucking everything safely inside sorts this problem and the user does not have to get intouch with his installer everytime the cable breaks unless your playing the old bandage cheese grater trick ? i thought you would have know better LOD

[x-land]

I hate to say it but I have to agree. I would not want to pay any installer 99USD + shipping to them to have only a 1/2 install which pretty much takes away the most important function of the UP in my mind: the ability to flash it from a PC which was not included with the PSP from $ony.

X-Land, every time I say you're great, I have to retract my words because every time you're even greater!

Although the destruction of the onboard resistors is all my fault, as is the launching of the 27 ohm resistor (did I say it wasn't my lucky day that day?), this definitely improves your third mod. It looks better, is easier to do (why didn't I think of it myself?) and better suits the FPC's direction. With the first version of the mod, you have to bend the FPC a bit to get it at the right place.

I know you make something wrong when try solder (maybe you use soldering station with much power or much temperature, or stay with tip to much on resistors). I try make and this variant for don't lose onboard resistors. I have experience and isn't problem for me solder direct on them but for who try first time make fine solders now have and 2 solution.
At my first solution FPC cable can redirect with a little attention without problems but at last solution it's more easy.

Maybe stagger the resistors on the traces to make it even simpler and use enameled wire to connect the resistors to the fpc, also there is no need to connect ground on the usb part of the fpc cable i beleive it's already grounded by the psp's usb connecyion as the UP usb ground is already grounded by the point on the fpc.

I know what you mean. It also happened to me once. Something happened that shouldn't have happened and I had to reflash my UP. So anyone who sells a UP mod without USB connector is limiting their customers to one-time use of the UP chip. And it's way to expensive for that!

Indeed there's no need for the additional GND connection, as X-Land already mentioned from the first version of mod3. But you can use it for additional stability of the mod. The extra GND connection stabilizes the FPC so no tension is put on the resistors and their connections.

The image from the news "links" to the UP modchip's USB interface instead of the PSP's USB connector. There are actually 3 alternatives presented by X-land, 2 of which use the PSP's USB connector as a dual purpose plug in and the other which you put the UP USB connector into the side of the PSP.

x-land - its the error you get when power is going to ground (pretty much the only error windows will generate on its own aside from driver issues).

Badxil: make sure your power is to the correct lead on both the UP's cable and in the USB cable mod, and be sure there is no short from the jumper wire on the PSP's USB port to the shield on it or other ground.

[Badxil]

i use an ohmmetre and it say 0.07
and when i invert GND and 5V nothing happen so i don't know :(

please make a good photo with your install and post here. Where you have 0.07 ohms? (betwen what points?)

[Badxil]

when i use an ohmmetre between GND and Y

[x-land]

when i use an ohmmetre between GND and Y
heres wrong. between GND and Y must have infinity resistance. in finaly at tutorial write clear if have 0 ohms (short) is wrong and must revert the fpc.

[Badxil]

Ok but when I have infinity resistance the UP is not recognize by the PC
I used Squirrel61 alternative Y point

[x-land]

but in this position you are sure its good power and gnd.
isnt recognize because have some bad at resistors solder.
make photo and i try explain direct on them. try make big zone from maiboard for can explain you how verify all connection.

[Badxil]

Thank's
I will try but my camera isn't good
I test the 2 resistor and they are good so i will resolder them

[x-land]

Verify that:

8060

Between:

1. A & E = 27 ohms same B & F = 27 ohms
2. C & A = 27 ohms same D & B = 27 ohms
3. A & G = 28.5 ohms same B & H = 28.5 ohms
4. C & G = 1.5 ohms same D & H = 1.5 ohms
5. Y & GND infinity resistance (that is very important)
6. put USB modified cable in port and at Y FPC point must have 5V. isnt need for power on console or put battery in place, just plug

I resolder the 2 resistor and it work but now i have some data transfert problem when i want to copy a file on the memorystick transfert begin then windows give me an error and i can't acces to the memorystick (I think i have a problem with the onboard resistor since i solder the resistor direct on it but when i test i have the right value 1.5)

Thank's for your help :)

[x-land]

try test after my photo and details from post. if you test direct on resistor and have 1.5 that dont means and connection with mainboard is good. if all tests from photo its good work 100%. and of course if dont have cold solder.

[Badxil]

thank's i will try this later
you re the boss

Edit 1. A & E = 27 ohms same B & F = 27 ohms OK
2. C & A = 27 ohms same D & B = 27 ohms OK
3. A & G = 28.5 ohms same B & H = 28.5 ohms 29
4. C & G = 1.5 ohms same D & H = 1.5 ohms 1.9/2.0

I have a little probleme with the onboard 2in1 resistor

[x-land]

betwen CG and DH i have 2 / 2.2
if that 2 / 2.2 its ohms its ok. but that value must have and direct on resistor.
Test and between E & F for dont have short (0 ohm).

4. C & G = 1.5 ohms same D & H = 1.5 ohms 1.9/2.0
maybe and one bad MM give you that value (i hope isnt my MM cause :) ). the resistor can be burn (infinite resistance) or good (corect rezistence). So i think its good if you have 2 ohm.

[Badxil]

I test all the connection but i still have this transfert problem
i can't write on the memorystick
I have another PSP motherboard i will try to replace the resistor

[x-land]

So,

On UP you can write. that means 27 ohms resistors and FPC install are good.
Windows can view memory card (PSP)? Files an folders can see in explorer?
Can read from memory? When its blocked at try write? What error apear?

[Badxil]

I can write on UP (I mod my PSP in july so the UP install is good :) )
I can copy files from memorystick to PC :)
I can format the MS under windows
When i select USB the PSP appear in windows i can see files and folders but when i try to copy a file on the memorystick there is no errors it stop and all the folders disapear i need to push O then X to reconnect the PSP :rolleyes:

Sometimes there is an error saying that the file i try to copy is ''introuvable'' i don't know the english word ''the file is untraceable''

[x-land]

hmmm. if you can do all what you say the transfer its ok.
From mod only one reason can be: cold solder at one 1.5 ohms resistors. and when make good contact with mainboard when is bad contact.
Strange is because only on write have that problem and maybe its other issues and mod is good.

[Badxil]

The transfert doesn't stop always at the same time
This problem appear after i desolder the 2 resistors on the 2in1 motherboard resistor
I think it is damage I will try to replace with another

[Badxil]

OK now it work :)
I desolder the mainboard resistor and solder 2 resistors (1.8)
I can flash the UP and transfert files on the MS but the PSP is not recognize as USB2 device
Thank's a lot x-land for your help :D

[givemestrenght]

hi this is my first post! propably i will go for the first tutorial and i have a question. i have to put out the motherboard so i can install it? you know. i am afraid for my new psp:o

[x-land]

what you want install???? For first mod isnt need remove mainboard.

[givemestrenght]

i want to install the first mod but i can not understand how exactly i will open my psp. can someone explain me?

[Lodis]

I got the first Xland USB Mod installed on my modded Psp some time ago. I stupidly picked up my Psp from the floor not realising it was still connected to the computer USB cable so the Modded USB connector became a bit lose but still worked 99% of the time when reflashing. After a few months, today USB is no longer recognised on my Psp Modchip and I had a look inside and the USB connecter has come totally lose now.

I know a guy who works in electronics but he knows nothing about the Psp or the Mod chip and has no experience with it. Do you think it would be a bad idea to get him to fix this USB connector part (side of the case)?

I have tried to contact Scroller but his inbox is full and I haven't seen him around here at all lately (for ages).

I am assuming that the USB connecter just needs resoldering on?

Would the guy need to know anything about the Psp to be able to do this so that it works again?

[tutti]

just letting u kno scrollers internet is not working. will be in a bit

[UP_PSP]

For using the PSP's built in USB port, do you need to modify the FPC cable? is there ANY way to flash this chip without the "usb end" of the fpc cable?

[p$p b0y]

hey, great finds ;) i was just wondering about the third option, with the psp usb and no other components, would the U.P only be active on that usb when its in programming mode? and the psp storage when its turned on from the xmb?

and do you take the two resistors from the UP usb and solder them to the fpc?

[Badxil]

Hi
I need some help :rolleyes:
During some experiment, on my UP psp i burned the 2in1 USB resistor
I don't know where i can get some 1.5ohms resistor in order to repair
I solder 2 resistor found in an old phone but the shot chotto camera doesnt work and the ransfert speed is USB1
So if someone can help me :)

[Squirrel61]

It's take a very long time, but finally I managed to repair my psp. Some time ago I decided to remove the UP because it was having problems (probably faulty connector on the UP board) and while doing that, I destroyed some PCB traces on my mainboard (my hot glue was too strong). Because I didn't have the time to repair everything, my psp has been dead for some weeks.

Last week, I repaired the PCB traces and resoldered two brand new 1.5 ohms resistors. Now everything is working fine again, including USB data transfer!

Thanks for all your advice, X-Land! I managed to get a second psp on which I will re-install the UP including your mod 3 version 3. I'll keep you informed on success.

[Badxil]

Where can i buy such resistor on internet ? :)

[cory149]

Where can i buy such resistor on internet ? :)
Google is your friend. I believe you'd need (size 0603 or perhaps the smaller 0402) SMT resistors; pretty much any electronics part source (ie: DigiKey, Mouser etc) should have them, though I am not seeing 1.5ohm as being a very common value. It's not really necessary to get a block (or even the smallest package size) like the original, just as long as it does what the original did (provide 1.5ohm resistance on each of the 2 traces).

[Squirrel61]

Where can i buy such resistor on internet ? :)
I bought it from Conrad Electronics, which is a German company with a Dutch branch too. They generally ship through Europe.

Indeed it's not easy to find 1.5 ohms SMT resistors. I bought some which were about 4 times the size of the original ones. It's no problem, they fit perfectly well on the outermost soldering pads when put on their side :D (the original resistors are soldered on the middle pad).

[Badxil]

Thank's a lot
I will try it later

Edit : I think i will buy this type of resistor

Here you go I made a mirror page of your third mod as your page was using java script to read peoples clipboard contents - this is just html so there is no java stuff running + you can save this page as you can right click on it.

Its protected original page for cant download content. Try remove that "mirror page" pls. Thx

[cory149]

x-land: have you run across any PSP with the same problem with mod 3 as Badxil?

One of the PSP's I have here now is doing the same thing... whenever I try to send a file over USB to the MS, it gets part way, gives an error and closes the window - UP writing/dumping seems fine. Everything checks out measurement wise. Disconnecting either of the usb comm +/- leads from the FPC (leaving the 27ohm resistor, the other lead+resistor, and V+/GND in place) lets the USB to MS work perfectly.

Very frustrating... I have even tried replacing the 1.5 block with 2 1.0ohm resistors, MS transfers work fine then, but cannot connect to UP. Any thoughts?

BTW: the english version of the error is "File Not Found"

[x-land]

Yes, i have some feedback with similar problem but was little procent and my mind go to other causes. Somebody tell my cant transfer with aditional (multi) USB port (with mainboard USB port works good).
I make my work with one old desktop PC (with 1.1 USB) and all works fine and for mem transfer and for programming UP.
But, today i try with one PSP on my laptop (have 2.0 USB) and I cant transfer on mem card (on desktop its OK).
Ill try study some filter for fix this problem.
Who have this problem post details for used usb port and what wasnt good (mem transfer, UP transfer or both). Thx.

PS. cory149: If can try and with 1.1 usb port post if its ok.

[cory149]

Thanks for the reply x-land ;)

I have a USB 2.0 + firewire PCI card and USB 2.0 mobo connection... no idea how to force it to enumerate as a 1.1 device on either USB connection, though I will check my BIOS as only my 1.1 mouse is connected to the mobo connections.

Glad it's not just this one PSP, others have worked fine before using the same connection and for a while there I suspected something was up on this one.

[Squirrel61]

If you can find a USB1.1 hub, you could try to put that between your 2.0 connection and the UP cable. Although in my experience, hubs don't improve communication with the UP...

[cory149]

No 1.1 hubs 'round here, and I don't much care for getting one through eBay or something just for this one test :(

I was digging around in this PC, and noticed that the driver comes up as "PSP Type A"... just thinking back and I know I installed a driver for PSPLink a long time ago, is it possible it should enumerate as a 1.1 device on it's own but because of the driver...? Windoze can be such a PITA sometimes.

[Squirrel61]

Maybe it's possible to install a 1.1 driver for a 2.0 root hub, but I don't know if this will make any difference. If you don't have any 1.1 equipped computer in your home, maybe you can check with someone else's computer. If it happens more often, it could be useful to install a 1.1 PCI card, although UP also doesn't like USB ports that are not on the mainboard. Is there anything USB-wise that UP does like?

In the past, I used UP on a variety of computers and ports, including 1.1 and 2.0 mainboard ports and 2.0 PCI card ports. I found the connection being most stable indeed on 1.1 mainboard ports with a not too long cable. Even a front USB with the cable that came with the UP caused problems already.

[cory149]

A spec of 2.0 is that it has to be backwards compatible. For example, I have 6 USB connections on my PCI card and 4 on my mobo - it amounts to 2 USB 2.0 root hubs and 5 1.1 root hubs. Also, the UP connection isn't a problem (it works fine as-is), it is the MS host that seems to be the one with difficulty, but only if both UP's serial +/- are connected at the same time.

At any rate, even if I do get it working as-is on this PC, I wouldn't want to send it home with even the possibility of a problem.

Just an odd though, but while doing somewhat random measurements to see if anything looked off voltage wise, I noticed when the PSP is in the XMB running off UP's NAND, there is ~1.4V on the UP's 5V in lead (relative to PSP ground, no USB cable hooked up).

[cory149]

TS3USB221 (http://focus.ti.com/docs/prod/folders/print/ts3usb221.html) (TI link)
USB signal switch seems to work well in this instance, both UP and PSP on a single cable. At $1.20CAD a part, not an overall expensive solution. TI also offers samples.

installed image and pinout (http://nds.cmamod.com/psp/TS3USB221DRCR_UP.JPG) (link)
Sorry for the lousy camera, I tried to add enough info that it makes sense.

Only problem I see with this wire-up is that UP is always dumping 1.4V into the 5V lead, so the PSP thinks a USB cable is already connected when one is not (in system menu USB mode). Not sure if this would affect other devices like the camera/gps. ~20 min of continual use and the chip's heat pad is cool to the touch, though where I placed it, it is going to get a chunk of thermal pad like the other chips have.

[Squirrel61]

Nice work Cory! Would a simple diode prevent the UP from dumping power into the chip?

[Zero000]

installed image and pinout (http://nds.cmamod.com/psp/TS3USB221DRCR_UP.JPG) (link)

my psp is famous!:D

[cory149]

Squirrel61: I tried a dual BAT18 sot-23 diode originally, and the .4V drop seems to have caused detection problems, though I will definitely try it again. A second concern though, is that where the switch is drawing power from will not get power with a device that is powered by the PSP itself, and without a camera or gps around (I sent off for a camera to find out for certain, though I don't particularly want one and it won't be here for at least a couple weeks as I have to import it) I can't test the voltages at the OE enable alternate point (or I would just wire the switch so that it is always powered, in low power mode, until OE get's enabled).

This switch has amazingly low current draw, too. 30µA peak draw when enabled and <1µA when in low power/bus disabled, according to the documentation.

Zero000: your PSP has been a pain in the behind since I got it here... it's unbeleivable how mangled the original board they returned to you was - it's even worse off than the first board which I soldered UP to 8 or 9 times before deeming it toast.

[Squirrel61]

Ha! I knew it! X-land, the Devilution team stole your idea!

Look here: http://www.psp-devolution.com/instructions/instructions.html

Scroll all the way to the bottom (or if it gets enhanced, to point 14, just below the pic) and read!


To be able to read/write/erase the NAND through the very own USB Port of the PSP we need to make a small adjustment on the USB Cable. The only way we could get this fabulous feature working was by using a free connection of the PSP's USB Port which is Pin 4. This means you must desolder the cable that goes to Pin 3 of the mini usb cable and solder it to Pin 4. Pictures to follow very soon...

[cory149]

Between the voltage shifters you guys have come up with, and the USB switch I found, almost makes them seem inept when they say "The only way we could get this fabulous feature working"... perhaps they mean more along the lines of "the cheapest way we could make it work and still line our pockets with sales from desperate broken PSP owners"?

[cory149]

Final revision, tested working with PSP camera (and believe it or not, this picture is taken by another PSP with the chotto cam in macro mode, about 3 inches away from the PCB).
http://img394.imageshack.us/img394/8448/finalswitchoi6.th.jpg (http://img394.imageshack.us/my.php?image=finalswitchoi6.jpg)
Reduced wire count, if I hadn't buggered the original 1.5 resistor bank there would be no need of the 1.5ohm resistors sitting on the PSP board. Added a BAT54-TP SOT23 diode to the 5V lead, PSP does not think USB is connected when it is not. Basically, the switch only gets power when 5V is applied to the USB power, and is only enabled and re-routing the signal to the 27ohm resistors when PSP is in programming mode. It does not appear to affect the circuit when not powered or when not in UP programming mode.

I was not able to get the camera working initially with 3.30OE on the PSP flash (going to camera crashed the PSP most times when the camera was plugged in), installing 3.40OE seems to have cleared up that problem, at least running from the UP.

[Badxil]

Great work cory149
Can you make a more detailed tutorial :)

Thank's

[cory149]

Sure, I'll redo the pinout image in my other post a few back with pinout explanations from a clean board image a bit later.

Initial testing on a fully working xland mod (both UP and USB work fine using 2 different cables), using just the resistors and the unused pin for power... camera does not work correctly - it captures one image then cuts out back to the XMB.

edit:/ I had completely forgotten about this... got partway and figured "I'll get a round tuit", but all I could find was a square one I guess... :(

Updated image for the TI USB switch. A couple less wires, and it should make more sense with the better image. Too bad I sent the one I rewired out without grabbing a pic, it's wireup shure beat the heck out of the test wireup I posted earlier.

[uprocks]

My PSP died yesterday so i thought i'd jus get the flasher out and flash it. Wrong my fpc had cut itself on the battery compartment and now i'm implementing the x-land mod with the modded usb cable. Jus wondering what is the best way to cut to the traces on the fpc???

[Ronbo85]

Hi x-land

Sorry to go off topic

I have not been able to find the thread where ("and I thought it was you") someone used a UP fpc with a dev, please see the attachment, thank you for the nice usb fix!

[JacKz5o]

I'll try this out :D thanks :)

[ck472006]

Well done. Pretty cool mod.

[mojarlets]

The USB has to work whatever be the situation but in this season of Christmas
I wish everyone Merry Chistmas and a Happy New Year. :)
May the coming year brings a new horizon of happiness for you.
