sorry if this question is noobie. My little brother just bought a new psp slim with 3.6 firmware and wants to downgrade. I have a fat psp and downgraded it to 1.5 and am now at 3.4 oe-b. I have been doin a bit of reading and looks to me like you need this pandora battery and magic memory stick thingy (all new to me never heard of it but) I am pretty sure i can handle making those as i have a custom firmware psp. But can I use on his 3.6 not real sure. I dont want to brick the little guys psp. Is ther anything i need to now which i havent read about.
