i'm using v3.11 now and i'm trying to update it to version 3.4~3.5
but i keep getting errors when i tried to update it.

anyone know wat's the problem i'm facing?



*add-it
and so i read that it's something got to with the idstorage keys.
now i'm trying to use ChillyWilly's KeyCleaner.
but it doesnt seem to want to work on my psp.

can anyone show me the correct way to launch this program on my psp?
wat i did was copy the PSP/GAME/ folder provided, and pasted it into my psp.

i tried both KeyCleaner v1.1 and v1.0 and it doesnt work

thanks in advance~

p/s:i'm using official firmware
