i have a psp 3000 04g model running 6.35 ofw. and i want to downgrade to 6.20 so i can install cfw. i have all the neccessary files i need to downgrade. so i run the chronotrigger download. press x and x again which took me to the SCE updater. but when i got the this message popped up:
"A later version of the system software is already installed.
There is no need to update. (CAAFFFFFCF7)"

and iver tried numberous times. same answer. so i gave up and thought id install another cfw, 6.35 pro b9. so i run the pro updater. press x to launch cfw which writes some files to the flash0 and it says rebooting. so i wait for it to reboot which took forever only to find out that it shut my psp off. checked the fw, still running ofw not cfw. again i try numerous times to initiate this proccess still none.

so can anybody help me with downgrading to 6.20 so i can install a cfw? thanks in advance.

Here is three things you can try.

1: Reset system settings.
2: Format psp memory stick...... first back up all the important files.
3: Update to 6.60 OFW then use my downgrade tutorial in my sig.

Ok ive followed these 3 steps. still no luck. says samething when i run the downloader trying to downgrade from 660 to 620.

so i tried downgrading to 6.31. went through. but when i tried to downgrade to 6.20 it wouldnt let me. i tried redownloading the 620 ofw thinking it would help but same outcome.
