Ok i followed all teh steps to make a pandora battery. Everything was going good until i backed up my battery to revert it when i am done flash my psp slim. For some reason it doesnt seem like the batter flashed because when it rebooted i was able to play games and what not. I took out the batter and mem stick and put htem back in reboot but it just loads the the XMB. i followed teh guide step by step.
