Things You'll Need
Instructions
Insert your magic memory stick into the PSP card reader and insert the Pandora battery into the Sony PSP with the device turned off. The PSP will automatically turn itself on.
Locate the game menu on the PSP once it boots. If you are running custom firmware, you need to run the application Pandora Battery Tool. Once the program starts, you need to press the "X" button on the PSP. Once prompted, choose "Flash only serial from ms0:/eeprom.bin."
Press the "X" button once more to exit the application after it writes the data back onto the battery. Your PSP will reboot and you will now have a normal battery, capable of being used by your PSP when engaging in normal operations.
