Trouble...please help

When I try to transfer games, emulators etc. onto my psp, it will show up but when i try to open it up it says that the file is corrupted. what am i doing wrong? ive tried deselecting the "hidden corrupts" tab but it still doesnt work. please help me

on your other post, you mentioned that you have 2.0 correct? If thats the case, then homebrews and hacks will not work for your psp, your psp must be 1.5 in order for homebrews and hacks to work.

but don't you worry, cause we have the downgradeable thing for ya, but just not yet though, still has to be release...

yeah i tried to delete 2.0 off my stick...apparently it didnt work. i dont know but i can still get into my web browser but my stick shows no 2.0 on it.

it doesnt matter if you delete it off your stick, you already updated your firmware, so the update on your stick can be deleted if you want. But theres suppose to be a downgrade soon, so dont worry.
