I originally had 5.00 M33-6 and upgraded to 5.50 GEN-B, but realized my emulators don't work. I know I can downgrade back, but I want to be very sure I know what I'm doing before attempting this.
I read the readme in the recovery flasher 1.60
So I just select the recovery flasher from the XMB and boom I have 5.00 M33? Sounds like a noobish question, but I'd rather be safe than sorry. I mean do I need to make a pandora battery? What do I exactly do here.Copy the RECOVERY folder from the archive to /PSP/GAME/ on your
memstick, so that you get a /PSP/GAME/RECOVERY/ folder containing the
apps EBOOT on your stick.
Now copy the official Sony 3.71, 4.01 and/or 5.00 Update EBOOT, renamed
as 371.PBP (401.PBP, 500.PBP), into the RECOVERY folder as well, or into the
memsticks root folder.
