how did you brick it, the most common way to unbrick is hellcat's recovery flasher and can be installed through the recovery mode if you have a psp with custom firmware already if not you need a pandora battery and magic memory stick
it does not have CFW. i was updating my psp to 5.02 and the battery came out.i try hacking it but it wont turn on with pandora and a Mmc.i used rainMMC
