You made a Pandora battery and when you put it in the power turns on but screen is black it is not bricked thoughI have a psp 1001b you are running 3.52?

ok

the Pandora battery is useless without a magic memory stick

make your own magic memory stick using the program above

when you have your MMS made, stick it in your PSP

THEN, stick in the Pandora battery

it should work
