i had a hacked psp since it became hackable. the tricky thing is. without a pandora battery its gonna be hard to hack an updated psp. there are certain requirements that need to be checked off. i dont really know if the hacking proccess has changed but you can check youtube.
when i first hacked my psp i needed a copy of grand theft auto liberty city stories and a certain psp firmware.
if you can figure out a way to downgrade your psp to 1.50 you are basically set.
as for the pandora battery thing it is basically a program that is installed via the psp's battery that can downgrade the psp from ANY firmware wheter it would be the latest or not. i hacked over 10 of my friends psp's with it.
in order to make one... you need to have a hacked psp. (which is gay) or you can buy one on ebay. but i dont trust it.
try googleing if you can. like "psp, your current firmware, hack, custom, how to," and stuff.
or mail it to d4rk.
