    i bricked my psp slim so i borrowed my friend's fat psp, made a pandora battery and magic stick (512mb sandisk) using UPMS, booted into despertar cementerio v3, backed up my nand and then pressed X to install firmware 3.71 m33. it said:

    Loading updater modules... OK
    Formating flash0...

    it stood their for about 15-20 mins, i thought it got stuck or something so i removed the battery and booted it up again. pressed X again to install 3.71 m33 in despertar cementerio v3 but again its been more than 45 mins now and its still stuck at the same formattin flash0 step. this can't be normal, how long does it take to format flash while unbricking psp slim? ..what could be wrong?

    First post, totally lost, and I have the same problem. Slim PSP - had it working on 3.71 m33-4, ran something on it, good, turned it off. Now bricked - when I try to re-pandora, it hangs on "formatting flash" - of course I didn't do a nand dump beforehand.

    How does one go about repartitioning the flash from the NAND tool - what is the NAND tool? Sorry for being a moron.

    best

    If you have a UPMS, when you boot to DC screen goto utilities(I think)and it has a couple extra programs, one being nand tool.

    Reformat flash and then go back to menu and re install firmware

    had to do this once on a psp after writing .prx file to the flash0 on 3.71m33 do this :Fixing your PSP Flash Memory Partition Tables

    There is a bug in 3.71 M33-2, when using the 'Toggle Flash' options in recovery mode.
    using it to write to flash may cause your PSP Flash Partition tables to become corrupted.
    You will need to use NandTool to re-partition your PSP Flash memory.

    NandTool 0.3b1:
    Download: http://www.sendspace.com/file/lopm79
    Mirror : http://www.zshare.net/download/56809643bd8998/

    Installing Nand-tool
    (most users can skip this step as I've included Nand-tool as a part of the Pandora Install Files)
    1. Download 'NandTool 0.3b1' and extract it to a folder on your computer, you will get a file called 'backup.elf'
    2. Insert your 'Pandora Memory Stick' into your PSP and connect it to your computer (or use a memory stick card reader)
    3. Copy the 'backup.elf' file and paste it inside the "KD" folder and overwrite the existing file.
    4. Close the USB connection and disconnect the USB Cable. (or take memory stick out of the card reader)

    Instructions on Using NAND-Tool:

    5. Make sure you have at least 33mb of 'free space' on your memory stick' for a original PSP, or 66mb for a slim PSP.
    6. Insert 'Pandora Memory Stick' into your PSP
    7. Insert 'Pandora Battery' into your PSP while holding the 'L' button to access 'Pandora Recovery Menu'.
    8. Hold the 'Square' button for 2 seconds to start the 'NAND Dumper' program.

    9. On the next screen, press 'O' to go to the next part of the dumper.
    10. Choose 'Dump from NAND' option and press 'X', choose "Nand-dump.bin' and press 'X'
    * Please wait while your PSP NAND is being copied to your memory stick *

    11. Once the dump is completed press 'X', now press 'O' to go back to the main menu.
    12. Select the 'Other' menu option and press 'X'
    13. Select the 'Repartition lflash' option and press 'X'
    14. Press 'Triangle' to confirm you want to 'logically format the flash'
    * Wait while the lflash area is logically formatted *

    15. After the lflash format has been completed, press 'X'
    16. Press 'O' to go back to the main menu.
    17. Scroll down to 'Quit' and press 'X'

    18. You will now be back at the 'Pandora Recovery Menu'
    19. Press 'X' to install 'Custom firmware 3.71 M33' and it should install custom firmware.

    After the custom firmware install has finished, your PSP should hopefully be working properly.
    I recommend you to make another backup of your NAND using 'NandTool' and making a copy of it to your computer.
    Overwrite the 'old non-working dump' with a new dump of your working PSP.
    If the 'flash' gets corrupted again, you can restore the dump instead of repartitioning and installing the custom firmware again.

    that is using this pandora mem stick Pandora Battery Files to install '3.71 M33-2' (Version 4) (~23.7 mb)Download: http://www.sendspace.com/file/91aeat

    Hey Guys,

    Thanks for all your help. The problem is - my Magic Stick (whoa, no puns, no puns) is a standard magic stick - I had the damn thing working on 3.72 m33 (-4 i think), ran something on it, turned it off, and now - nothing. Do I need to get a card reader to alter the contents of, or remake the magic stick, to give me more options? I do get the menu to install custom or standard 3.71 firmwares.

    I can't boot USB mode because I can't get anywhere on this damn thing, brick mode in full effect. Am I f'ed? Maybe I just don't understand exactly what I need to do. I don't see the utilities option so I guess I need to remake the stick. But then I'll need a new PSP for that, right?

    I also read somewhere about the possibility (if I ever manage to resurrect this revenant PSP I have here) that I might lose the ability to read from the discs by damaging something else?

    Shoot, I shoulda left this for the pro's. Jailbreaking iPhones is one thing, but man, this is an entirely new ball of wax.

    yes you can recreate the memory stick on a pc with a card reader go here for the guide: http://forums.afterdawn.com/thread_view.cfm/610313 you might want to try that first to see if a file on the mem stick is corrupt but what it sounds like is the partitions in your flash may be messed up so you may need to follow the guide above or use rickem suggestion

    For sure my partition tables are thrashed, and that's the problem. There's no other reason for it to hang on "formatting flash0" indefinitely. But when I boot DC menu, I only have 4 options - install factory 3.71, custom 3.71, dump nand, read nand. I can't put it in recovery mode. I have to trick my pandora installer into using the nandtool somehow, right?

    Hey Wasted,

    Just wanted to say thanks - with some tinkering, on Vista, no less, I managed to get it back. If you change the file in kd to the backup.elf from nand tool, the DC menu doesn't change. you have to hit square for dump nand, and all the nandtool options come up. repartition the flash, and it's gravy.

    i haven't tested umd on it yet, so we'll see if that held. i doubt it, but at least it's a resurrected homebrew!

    anyhow, thanks again, i really appreciate it. this is a very helpful community...

    Well - now here's something weird - it will work one time, i.e., I can play anything - snes emu, ffVII, etc. - once - and then after I power down the machine, it bricks. I repandora, repartition flash, reinstall 3.71 M33, it works once, then brick.

    Weird! Anyone seen this before?

    ok now i have a problem while doing these steps

    12. Select the 'Other' menu option and press 'X'
    13. Select the 'Repartition lflash' option and press 'X'
    14. Press 'Triangle' to confirm you want to 'logically format the flash'
    * Wait while the lflash area is logically formatted *


    while the lflash is logically formatting i get something that says:
    ERROR: ran out of NAND for lflash exiting in 10 seconds

    after the downgrade and cfw completes it asks you to press x to turn off your psp you must press x or you brick your psp if you just shut it off use the pandora again when it completes press x then remove the pandora battery and plugin the psp it should boot normal
