Custom Firmware 5.50 GEN-B Released.

GENyUS and the PSPGen crew have just released PSP Custom Firmware 5.50 GEN-B. Note this is for PSP-1000 and PSP-2000’s TA088v2 or less motherboards only. Not for PSP-3000’s or TA088v3> PSP-2000’s. 5.50 GEN-B introduces a few minor changes. There is now a Pandora battery maker in the VSH. (You can make your battery a Pandora battery or back to a normal battery right from the VSH Menu) of course this is on supported batteries / PSP models that you can make a Pandora with. The PSN store is also working in 5.50 GEN-B.

    CFW 5-50 GEN-B

    help !!! i just upgrade my PSP-1000 series to this version… everythings works fine but then i found out there is a problem, when u turn off or under standby mode and try to turn on again, only the green power indicator are light up, my screen went black and no sound, memory card slot in and out with no respond. tried take out the battery and plug it back it turn on by itself and i need to manually turn off by holding the on/off button for couple of second. and tried to on again with the R1 button pressed.. but cant too.. not even can access to RECOVERY tool system…

    when i took out the battery and plug in the AC adapter, press and hold the right key button + R1 button it works and can access into the VSH menu and works normal..

    hope for solution on this 1…
