    What motherboad is your PSP?

    If it's non TA-082 and is a 2.71 firmware, use this. http://www.psp-hacks.com/file/755

    If you want to update to 2.71, then go to on your memory stick PSP/GAME and make a folder called UPDATE. Then make your update file called EBOOT.PBP and it shouldn't say corrupt anymore.

    DO NOT use the link i gave you if you have a TA-082 motherboard, it will be a 100% brick.
