I know Pandora-ing is good and all, so what do i do if i need to reverse it? I need a tutorial please.
THNX VRY MUCH in advance

In most cases, the software program on the psp that you used to Pandorize your battery has the option to un-pandorize the battery.

So you would need to plug your psp to your charger without the battery in, then put it in (so that you can boot your psp and still have the Pandora battery in) then go to whatever pandora program you used and choose the right option.
