    hey guys, i have this stupid little problem thats been bothering me since 2 days ago. i cant seem to find a way to fix it.
    i changed my psp to a 3.51 M33-7 custom firmware 2 days ago. at the time it was great, i ran my metal gear iso right off the memory card without any iso loaders. then i downloaded a few demos and it ran perfectly.
    after i finished playing the demo i went back to metal gear iso, it wouldnt run, i got the black screen and had to manual shut down. i tried several other iso's (DBZ, BLEACH, tomb raider) and they didnt work either, i got the same frozen black screen.
    so in desperation i switched my memory card into an old one that still had metal gear and Devhook 0.52, i loaded the 3.03 emulation and iso, it worked fine. so im like wtf.
    is there anyone out there who encountered the same problem or is able to solve it?
    thanks in advance.

    place it in that folder and try it out. and make sure in recovery that the firmware is in 3.51.

    i know. well best thing to do is system restore. and if that doesnt work then you have to downgrade to 1.50 then back up to 3.51.

    3.51m33 is a custom firmware :)
    And the 2nd giude in the link shows how to upgrade from custom firmware ^_^

    But well, I would recommend you to downgrade to 1.50 and then upgrade to 3.52m33-4 :)
    I'll find a guide for that and edit my post ^_^

    EDIT : By taking into consideration THIS (Click here) thread, I think you'll have to download hte file "PSP35" gave you and put in your ms0:/PSP/GAME/RECPVERY/ folder if it turns out to be an EBOOT.PBP and then :-
    Boot into recovery mode i.e Completely shut down your PSP and then when starting your PSP, hold the R1 button :)
    Then you'll have to choose the "Run program at PSP/GAME/RECOVERY/EBOOT.PBP" option :)

    3.71 m33-4 is best firmware. it plays almost every game and no problems.
