hey, dudes. i was trying to put Ultimate Blue III theme on my 3.52 m33-4 PSP (i've put it on there before) and when i exited the program, it didn't boot to the XMB, but froze on black and shut off. i then loaded UPMS and (being a RETARD) just wrote my NAND backup file (.bin) to my flash via elfmenu.(i created the backup on a DIFFERENT PSP just to let you know) *that was the bad part huh?* i then exited UPMS and tried to boot. no boot. just a black (yet still lit) screen. so i went back to UPMS and entered Despertar Cemetario (like i should have in the first place) and the screen went COMPLETELY black. (no light) i tried to use the brightness button, but no prevail. i noticed that it still was on though, so i pressed (X) cause i remember that being the "install 3.71m33" button. the lights went off and stuff for around 2 minutes. then stopped. i assumed it was done so i pressed (X) to let it shut down. i then rebooted. and it WORKED!!!! but it will not read discs now. it doesnt even attempt. it just comes up saying "Disc Cannot Be Read". plus, the brightness is all messed up, and the XMB sometimes doesnt want to run in full CPU speed. what should i do? will Chilly Willy KeyCleaner help i hope? (i hope i didnt totally mess up the IDstorage. (thats what is messed up right?) thanks in advance.
