What firmware to use

I'm currently running 3.30oe-a, was curious what the "best" custom firmware is right now and how I would go about getting it installed. Would I have to revert to an older firmware? Or is it possible to get an installation of m33 on a psp currently running OE?

i would suggest 3.52M33-4 and yes u can just update to 3.52M33-4 from OE firmwares

heres a link to 3.52M33>> http://pspupdates.qj.net/CFW-3-52-M33-h ... /aid/98418
