something is totally screwed up with my PSP's firmware. i was sitting at 3.52 M33-4 for months and it worked like a charm. i decided to upgrade to 3.71 so that i could keep up, and now my PSP doesn't do what a PSP is designed to do. i've tried to downgrade with this 3.71 M33 - 1.50 downgrader, but the program just says "extracting special prx's from pbp..." and then the PSP turns off and nothing is changed.
is a pandora battery the only other chance i have at getting my PSP to function again?
(to the mods: i know the last thread i started mentions this, but i needed a thread with a more relevant title to my problem.)
