You don't need gen firmware just cfw all you need is a homebrew like psptool or even the recovery flasher has that option. (I think) If you don't have your charger on hand just use test m33 mode if you still have dcv8 on it.Chris_Skylock said:YES YOU CAN. If you patched it via software, you can revert it back. BUT....if you hard mod it, buy anohter battery.
Install GEN firmware and fix it from there.
