Pandora's Battery not working anymore

[hooliganbandit]

I bricked my psp again so i unbricked it with pandora and then went to upgrade it to m33. the updater told me i needed 75% charged battery so I put the pandora's battery in and tried again and something happened, i'm not sure when or why but my psp shut off and now when i go to unbrick it once more, after it says formatting ok, continuing in a moment... , it goes back to pandora's main menu. did i mess up pandora by putting it in during the upgrade? I checked my ms and i still have all the files. Any ideas?

maybe you messed it up, you could try with another pandora battery and MS

I just tried to use it on someone elses psp and it works. I dunno what to do.

OH! I just remembered something and it is probably what caused it... I flashed a 1.5 nand to a 3.52 m33. Is this what caused the problem? Is there anyway to fix it?
