    Just wondering, But im pretty sure somebody thought about this. I have not read it anywhere so just out of curiosity.
    Im not familiar with binary or coding or programing but if somebody could look into this; Check it out.

    lets say you have a 3.10FW PSP. Download a official sony FW update, for example 3.40. Something higher than what you currently have. If you put it @ ms0:\psp\game\update . The psp will see it as and update (obviously).

    But, what if you can edit the EBOOT update with the 1.05 FW to make the PSP think its a 3.40 FW instead of a 1.50?
    Is this possible?

    I think the eboots are signed and tampering with them will destroy that signature. idk for sure though.

    I tried opening up 3.50FW with word/note pad in WINXP, all i got was gibberish. You could make out a few things/words but nothing solid where u can compare both. (both = 1.50 and 3.50 Official sony FW)

    I don't think notepad is the suited program to tamper with EBOOTs.

    good try man but oyur better off with a hex editor and any way like some one said the eboots are signed or what ever so once you save a modified one the psp wont use it

    It was the first thing they patched, Use PBP Unpacker.
    As soon as it has been changed the psp won't boot it..
