So my friend sent me his (phat) pandora battery so I could mod my (slim) PSP. I made the Magic Memory Stick myself, using PSPGrader, and as far as I could tell, everything went well. So I pressed and held L and put in the battery. The light came on, which means the battery was working. But the menu for installing the CFW never showed up. So I removed his battery, put mine back in, and tried making the Magic Memory Stick again, using a different IPL. Tried putting the battery in again, but the same result. Power but no menu. So I tried again using the third IPL, and again got the same result. So I tried again. Only, this time the power didn't even come on. So I assumed my problems were because my friend neglected to charge his battery before he sent it to me, and I plugged in the power cord. The charge light came on for about two minutes, and then it turned green. But the battery still wouldn't work. I've tried charging it about a dozen times, but every single time it stops after two minutes and the battery still doesn't work. So, could someone please tell me what the hell? Because I'm completely lost, here.
