i got a serious problem...cause i wanted to change the font of 3.03 OE-A with PSP Filer, and when i did that and rebooted my psp i get a Blue Screen thats says that i need to press O, and when i do that i still get that Blue Screen.
Now there is a recovery mode what i can still enter....but i really dont know how to use it so if someone PLEASSEEEE could explain me how i can restore my 3.03 OE-A
