I tried to downgrade it but in my recovery menu there's /PSP/GAME/RECOVERY/EBOOT.PBP and not UPDATE.PBP (as u can see in the picture).
After selecting the Run Program at (...) the screen goes black and after some time the PSP shuts down.
I even tried to change the file name back to EBOOT.PBP but without any luck. Any ideas?
I am downgrading from 3.40 OE-A cuz I can't read CSOs on it...
Cheerz & thanx in advance
Pedro
btw: sorry for the n00b question
