Ok..I had custom firmware version 340 OE-A....then i decided to go down to 3.03, but I did it the wrong way somehow and now my PSP is half bricked. When i get into recovery mode, i can't execute the EBOOT.PBP in the recovery folder. I tried to flash the systemctrl.prx file but it says "error reading from the memory stick"...i also cannot enable usb mode so i have to put the memory stick on an adapter. Anyway i think whats wrong is that the PSP cannot recognize my memory stick. Does anyone have any suggestions as to what I can do?
