I was trying to turn my battery into a pandora by running v4, but my firmware is 3.10 OE-A'. After reading up a little more, it seems as though i should have been running CFW 3.71+ before doing so..?
Anyhow, my PSP won't startup with the battery in it. It does start with only the AC adapter and no battery. Is there a problem with my battery? Is there a way to get my battery working again without the use of another PSP?

i tried installing Pandora Installer for 3.xx R3 and Despertar del Cementerio v7.77 just before the problem.
