Ok I finally decided to downgrade my PSP 2.71 TA-082 and and succesfully did it. Thanks for the guides and all the other people that helped make other guides and the actual downgrader. I have one question though... how do I play my ISO's?? Do I need DevHook for this?? I tried making a ISO folder and put a game in there but it wont show on my PSP.. I put in a UMD disk and it shows the UMD disk game and not the game I have in the ISO folder.. also where do i put the ISO folder??
