    you can either use the universal unbricker v3 i believe...
    did you tamper with the flash0 files??
    if you did, did you copy the original files o your desktop?
    if you did you can just put them back in there...
    thats what i do

    Just reinstall 3.71 M33 from your magic memory stick.

    If that fails, your only option is a restore of a FULL NAND flash backup (but if you didn't make one from your own PSP then it might not work).

    As a last resort, go to a friend with a PSP - then install 3.71 M33 and backup HIS NAND flash. But only try this as a last resort, as his NAND image might not work on your PSP.

    he cant re-install 3.71m33 from his memory stick because he said that his xmb screem wont come up, so he can either do the nand, but it wont always work, or he can try despertar del cementerio or universal unbricker

    Heh, but the magic memory stick is made with despertar del cementerio!

    And despertar del cementerio needs no XMB, just the magic memory stick and pandora battery.

    However, you could be correct for the reason that despertar del cementerio relies on Flash 0 being more or less intact.

    So a full NAND restore may be his only option after all...

    he can do that, or he can try UPMS_installer
    and downgrade his psp to 1.50
    and then use the despertar del cementerio to upgrade it back to 3.71m33

    1) When the PSP was WORKING, insert the pandora bettery/magic memory stick and power up the PSP.

    2) Look at the options, one of them says "backup NAND" (usually Square)

    3) You now have a 32MB NAND backup for PSP FAT or 64MB for slim.

    This MUST be done with a working NAND - at best from your PSP, but you can try the nand from a friends PSP.

    1A) Once you have a NAND dump, just insert the pandora bettery/magic memory stick and power up the PSP.

    2A) Now select "Restore NAND flash logically - DANGEROUS!"

    3) Wait till it finishes...

    Now test your PSP.

    By the way, is yours a PSP FAT - or PSP Slim?

    Try re-installing an M33 firmware from scratch by inserting the pandora bettery/magic memory stick and installing it from there.

    Alternatively, if you made a backup copy of your flash files - just restore the files into your flash from the backup via USB.

    Ok I agree... Do that.
    But that is very dangerous and do it only if it's the only way of recovering your PSP!!!!

    BTW, How did you try to install the theme using the recovery menu?

    P.S. Psiomiadis, he can't do any of those since his PSP is bricked he cannot connect via USB to restore the flash0! And he can't do the first option because he mentioned that it failed while loading the PSAR to the RAM.

    And haghandi, sounds to me you have accidentally overloaded the flash0... Go to this link and that will show you how to fix it.
