Bit of an odd one, I upgraded to 3.40 to get Command and Conquer to work, but I noticed I couldn't change my cpu speed. If I try, it gives me the 'settings information is corrupted' message.

I've gone back to 3.03 oe-c, still the same, and I've even tried using the recovery EBOOT to go back to 1.50 and back to 3.03 oe-c, but it's still the same.

Any thoughts???

you cant change it using recovery? or in the game?

either bad iso or its ur flash

I can change it when Im running gpsp and other apps, but I cant change it in the recovery menu...

all you have to do is either reflash your psp. or upgrade to a higher custom firmware. the higher firmware equals less customization.

i had that issue before. I just reinstalled my f0 and f1 from a backup i had previously.
