i was wondering what the best way to go about downgrading a v 2.81 psp to 1.5, because i got the new tony hawk game for my b-day and dumbly upgraded right away, and now i cannot play my homebrew games, and my UMD reader doesnt work, so i can just upgrade to 3.03 and then use my GTA:LCS to downgrade, because i think mine is upatched, but i cannot check because my PSP wont read the disc, so could someone tell me if there is any way to do this?
