ok so i made the magic mem stick and pandora battery, i wanna downgrade the psp slim and when i turn it on and press x nothing happens, maybe i have wrong files, i have the 1.50 eboot on there maybe i can go straight from 3.71 to custom firmware. also can i use pandora gui to put custom firmware files and go straight from 3.71 to 3.71 m-33?
thanks
