yeah. i have a test for you. i haved tried downgrading and looked for xploits for my psp 2.01 and i havnt had anyluck. ok. i remember when i was in Dave and Buster (gaming and drinking place) and i slamed the coin pushing thing agains the side and it starting saying things in chinnese or something like that and spraying out coins. ok. my idea for a downgrade/explot (my be the best yet!) Take your psp and throw as hard as you can against your wall. Turn it on and see if you see any chinese writing or any code. If it dont work. Repeat Proccess!
