Here's the sad story. I have a phat PSP running CFW 3.80 M33-5 and had just installed the custom MGS sounds, which was great and I got thinking that I would install a custom battery icon. Well that was a bad idea! I placed a custom one in the flash0/vsh/resource folder, replacing the old one. Now however, with the custom one in there the PSP won't boot up. I can get into the Recovery Menu (which I hope is a good thing.) but as soon as the Sony logo appears it freezes and turns off a small while after that. It's really worrying me. I have no idea what to do. You guys are literally my only hope. I don't have a Pandoras Battery, but if it's the only way then it probably wouldn't be a problem... Thanks in advance, everyone.
