My mate want's me to try and put custom firmware on his PSP slim 3003 pb, system software 6.20.
Is this possible? I've read various threads online and some say yes and some say no due to the motherboard.
I recently put custom firmware on my PSP 1003 by upgrading it to offical firmware 6.35 then installing 6.35 PRO-B. Could I do the same to my mates slim or will I end up bricking it?
Any help/advice would be gratefully appreciated.
