i have a psp fat. i bought it when they first came out so whatever style that may be i need help downgrading it. i only have one but am having trouble downgrading it because i know no one with Pan's Battery or a cfw. i want to do it myself. i'm not too worried about the battery cuz i can buy a new one of those but a new psp on the other hand is a little out of pocket range. please help. i'm running an official fw 3.71 and am just trying to get it down to 3.52 so i can get some of the hacks i've aquired and maybe even get it up to a cfw m33 - 4 or whatnot.
