I am getting really bored after my psp 2000 slim got bricked for over six months now.I've tried everything possible but it is still totally bricked...i was using a pandora battery before i made it normal again.Immediately i insert the battery, the green light keeps showing and doesn't off.I hold the R trigger but the screen still remains blank...and i've forgotten the software version that was on the psp. Please i really need some help.:(
