i took your advise and downgraded, I did the autodowngrader(http://www.psp-hacks.com/file/605) and when i got to the step were you have to restart your psp after the flashing light urned off. it turned off for me. i just figured it was supposed to do that and turned it back on. then the psp was blank, the lcd screen didnt work at all. im like *****! now, i have a expsinive paperweight.
I know that u can replace the motherboard to fix it, but is there any other way possibly to fix it? :rtfm:
