i have a quick question. Because of some physical problems with my psp (for some reason the O button broke slightly and now hangs when you turn it around) i have to find a way to return it to the official firmware in order to return it to the store since i got an extended warranty on it. Yes i know it sucks, ill lose the ability to play backups on the memory stick but its something that must be done. Anyways, anyone know of a way to downgrade the psp back to 1.5 or can i just update the firmware to the official 3.5 firmware. i currently have 3.40oe-a on a TA-082 PSP. I did the downgrade when they came out with the 3.03 downgrader, and according to the info i had read, because it was 3.03 some files were supposed to be left on the psp and reflashing it would cause bricking. ive also heard they sell separate buttons for it, but opening it would void the warranty on it. what would you recommend?
