a stupid move by me

No.

Pandora battery is your only way back to homebrew.

Well you dont have to physically mod your PSP, just the battery.

Look in my signature for a cheap Pandora battery. It cost 10.50, takes forever to get to your house; but it works well and is easier then modding your own or buying one of of Ebay, then use the Despartor Cementario link in roxfox's signature to get an easy installer fore 3.80, then get the 3.90 update from dark-alex, then brew away!
