Okay, my old forum name was "TheTrueAnimosity", and I used to be super into hacking (I was the owner of an 800+ member PSP hacking site, mainly an FTB2 clan, WeAreChaotix), but I put down my PSP for awhile to focus on school.

Well, I decided to pick up my PSP again, well, my brothers, mine is broken, and I belive his was 3.73 m33, or something like that (I don't know what the new firmwares are).

Is there a way to upgrade to the newest (5.0 I believe) without having to use the pandoras battery? (I lost mine).
