When I was trying to install a custom theme via flash0, I think I may have deleted a wrong file or something because when I rebooted my PSP, the power light would go on for about 15 seconds and shut off, with nothing on the screen. I have a PSP 1001 runing 5.00 m33-6 (I think that's what it is). Please tell me if or what I have to do to fix it. Thanks.
