Pandoras Battery

[AvengedSevenfold Fan]

I unbricked my psp, but the process was a little odd. when i turned on the psp with the battery and mem stick, the screen turned off, so i couldnt see anything. i just guessed and pressed X a bunch of times, and it worked. when i turned on my psp, the screen was off, but i could turn it on with the screen button. i tried putting in the pandoras battery and mem stick in again, and the same exact thing happened. does anyone know why this is? and could someone tell me the orders of the buttons i will have to press in order to un-pandora a battery?

You may have an idstorage problem its the reason psp's have had black screens in the past, is your psp the slim, cos if it is this a known problem and a new set of files have been released by DA to give slim users the screen back while using pandora.
As for changing battery back.
1 remove pandora battery
2 start psp with ac cable inserted
3 re-insert battery while psp is on
4 run the pandora battery creater again and choose the option to return battery to normal.
