Also, if the battery lcd lights up green when you put Pandora battery in it then it works. If your PSP doesn't light up immediately when you put the Pandora in then it's something wrong with the battery.
How do I know if my battery is capable of being a pandora?
It's an official sony 1200mAh, but it's not the one that came with the system. I had to buy this one (new) when I accidentally broke the first original battery.
I fully charged the battery before using it, but I guess I'll try it again. But the pandora should work even without the MMC, right? I mean, just to see if it's working.
This happens to me too. I've read on another psp forum that there are newer, possibly as much as a year old, Sony brand batteries that cannot be pandorized with the trace 19 method. Your best bet is probably the recent thread on here with a link to a site which sells a tool battery and magic memory stick combo for $25
Is there any thread where I can find someone and maybe borrow their tool battery? I live in a very populated area, San Fernando Valley CA. Maybe that's too weird, but I'm really getting sick of this hacking mess.
