PSP downgrade???

    I just bought a new PSP with a new motherboard. Then update to firmware v3.50.

    Is there any chance to brick the PSP if i'm downgrading?
    Do I have to do anything before downgrading by following the instruction in the 3.50downgrader?

    Any special note?


    Thank you for your helps

    yes there is a chance of bricking, but u have the same chance of bricking with a real sony update as downgrading. nothing special to do.

    So I just follow the instruction in the 3.50downgrader.

    After I downgrade to v1.50 then install custom firmware 3.40 oe-a, Can I still go back to v1.50 and how?

    Thank again

    yes that is correct.
    u can recover back to 1.50 at any point. heres the recovery file

    to use this, put it in /PSP/GAME. then run it from the recovery mode.
    to get into recovery mode, turn the psp all the way off, not just sleep, and turn it back on HOLDING R. then go to run program at /PSP/GAME/RECOVERY/EBOOT.PBP

    It's almost the same as the OE's. Since Dark_alex stoped his OE development, the russian team picked up where he left off. 3.51 m33 allows you to run games require firmware up to 3.51.

    hmm.... read the instruction.... it looks hard.

    Well, Dark_alex v3.40 OE-A is good for now.

    its the same installation. it just takes a little longer in the m33updmaker stage.

    Yes. There is hope for your psp still.
    First, you will need Luminus the game. The actual umd.
    Upgrade to 3.50 (DO NOT use network update, it'll give you 3.51, then it's over for you), use Noobz 3.50 downgrader to get to 1.5

    From 1.5 you can upgrade to 3.40oe or 3.51 m33, both are custom firmwares that let's you do everything that you hear psp can do.
