if hard modding the battery didnt work, I would suggest soft modding it. Ise the pandora battery creator program on your psp. Then you can turn it into a pandora without having to worry about the pins. And to answer your first question, its a good thing that you had an extra battery around because the psp battery model psp 110 can't be turned into a pandoras. That's the one I have so for now I'm stuck on stupid ofw until I can get my hands on a battery that I can make pandoras. No store seems to carry psp batteries. Oh well. Best of luck.
