nandTool 0.4 Final NEO Aug 20 2008 (Des.Cem.M8 - friend of Despertar_Cementario)
with the elf loader and USB integrated I now nickname it Des.Cem.M8 - friend of Despertar_Cementario (somewhat jokingly).

Added a small tool so DC6/DC7 can be turned into dual booting main menu as well as load a screenshot.prx so that it will be able to in DC6/7's menu (though, not in nandTool's menu at this point)...

Thanks to 3r14nd

First final release in a while
0.4N Final NEO can be found here (link).

Main menu:

USB pop up:


Read the readme before asking any questions.

Keep in mind, while I have tried to ensure everything works as it should there may well be unexpected issues that arise under 4.xx firmwares. I don't and never have believed writes to NAND while the firmware is currently running from there would turn out safe.

0.4NEO (Aug 20 2008)
-----------------------------------

• fixed ids dump/restore messages leaving a blank line at the bottom sometimes
• made fade in/out consistent in menu (no fade ins)
• created logical flash menu option and moved repartition
• added partition integrity check to the logical flash menu
• added splash screens (main splash and warning screen, both can be disabled by the iaccept file)
• added consistent boxes to menu selections
• fixed info page to allow O to return
• corrected usb/usbhost mounting to work with the kernel prx and 4.01m33-2
• separated kernel functions into ntbridge.prx (prep for eboot version)
• hold square while booting to see USB messages instead of default halt on error
• adden in various full screen fades (not 100% yet)
• added fade effects to gfx rep.
• corrected a bug in elf menu (launching nothing when no elf were present)
• corrected a bug in elf menu that did not display "file launching" info
• fixed a bug that did not allow cancelling of usbhost connecting
• format partitions disables scramble for FAT PSP (for custom firmware)
• all dialogs should be fully functional now, slim idstore should dump/write properly
• added lines and boxes (eye candy)
• corrected a bug that would not allow proper selection of files after 23 (increased to 26 onscreen)
• fixed a bug where overwrite was not possible when dumping
• added progress bar
• added support for usbhostfs
• moved usb/usbhost prx required location to ms:/elf/prx
• underscore is displayed as a space in ELF and nand dump selection menus
• file extension is no longer displayed for elf or nand images
• key dumping folder name increment is now more like nand dump increment (automatic though)

Previously...

Changes in 0.3b1:

• disable power switch while NAND read/write functions are being processed
• undocumented method to attempt to ignore bad blocks when writing to NAND
• dump/write methods redone, base directory is now ms0:/nandTool_dumps/ instead of root directory
  -no longer relies on specific file names
  -write menu will only show files with the correct size for the hardware
  -more than the specific number of files can be utilized
  -dumper adds relevant info to filename to try and make it unique
• identifies PSP version
• added info to main menu, displays info collected at app boot
• MS to USB mounting via select key in the main menu
• idstore dump to key files (slim and fat)
• logical write idstore from key files to NAND
• creating a file with the correct name along side the elf will auto skip the warning screen (see warning screen for the file name)
• integrated ELF loader
• option provided on des.cem MS installs to format all partitions
• supports being a des.cem resurrection.elf replacement (quit is replaced by shutdown in this case)

BTW: 0.3 released as beta because I was too enthused to wait 2 or more days until all my retesting of all functions is completed, as well, there are cosmetic issues with some of the text feedback which still remains to be corrected. So be warned, BETA = somewhat untested but with no fatal flaws I could find with minimal testing of all functions on a slim only.

0.3 Beta1 can be found here (link)

Simply beautiful, thanks so much for constantly updating such an awesome
program.

thank you very much!

Great Cory. Thanks!.

wow great work cory.......i did'nt think your tools could get any better....
thanks for sharing your works with us and i can't wait for the full version now......once again thank you for such great tools.....

Good Job. I love this thing, so much more functionality than the regular DC_3
I have a question: Is it common to have NO bad blocks? I have none on my Slim PSP, does this happen a lot or did I just get lucky? Thanks.

Somewhat common I gather. Until I got a slim I had never seen a factory bad block on a PSP and in the early few weeks of having one it took me a bit to find someone with none; though, I have seen tonnes of people freaking out over 1 bad block (16KiB) thinking it is something that needs to be "fixed" or that it is the root of all evils with regards to a PSP not booting - with little cause to actually believe so (hence the note on bad blocks.) In fact, I have gone out of my way to preserve a bad block that I could have erased simply because I believe it was marked as bad for a good reason.

Time will tell, a NAND tester will be added along the way to nandTool somewhere (along with recommendations to never use it.)

Thanks for the ap Cory. A truly useful, interesting and excliting development.

FYI, both mine and my son's Slim PSPs have no bad blocks.

is it illegal to share idstore key files in the forums? because i could share my slim´s keys. and fat psp files as well.

btw do you see any light for full functionallity recovery?

Very very nice cory, works very well with UPMS. keep up the good work!

also I have no bad blocks

I don't see why it would be illegal, though I can definitely see how it could be used against the person who spreads their keys publicly. Out of respect for the forums I post at I reiterate the message: "DO NOT ASK FOR DUMPS HERE" as I don't want to see any trouble for any of the site owners. Also with the hope that $ony does not gain access to any users keys (generally unique hardware identifying information) I don't recommend sharing keys publicly.

In all honesty I don't see full recovery ever happening without some type of leak from a production or repair center, but that is just me and there are far brighter people working on it than myself. Though, I can envision a idstore bypass for specific keys, given what little I know, and it has been suggested that Dark_AleX may be considering looking into such a thing... until then though, most functions will be better than next to none.

Oh, also, don't forget those who'd use this method, there are also ways to recover the original MAC address for idstore.

Is it possible to add firmware version to filename like PSP NAND magager does?

You are free to rename the files to whatever you want after they are dumped, just like nandManager which always dumps to nand-dump.bin (or nand-dump_####.bin). Of course, if you have never used nandManager I don't blame you for beleiving those screenshots were of files that were auto named.

W.I.P. for 0.4: progress bar, integrated usbhostfs support, info bar, cleaner file listings, unified dialog box for status messages, optional logging to file of status messages, code cleanup.

Considering methods of obtaining fw version from files in flash, plausibly attempting to extract act.dat and 1seg file from flash when doing a dump.

thank you for your hard work.

Do i need to make a new dump or can i use a dump from an older version to be able to restore gaming etc in xmb ? and how can i restore my mac adress?
