Things You'll Need
Instructions
Turn off your Sony PSP and remove its battery from the rear of the device. Insert the Magic Memory Stick into the PSP's memory-stick reader on the left side of the device.
Insert the Pandora battery into the PSP's battery bay on the rear of the PSP. Slide the power button up to turn on the PSP. The PSP will be in service mode when it turns on. You will see a black menu with white text if you succeeded in putting the PSP into service mode.
Plug the PSP charger into the PSP with the Pandora battery inserted into it and allow it to charge for at least five hours before trying to use the Pandora again if Step 2 failed. This will insure that you have a fully charged Pandora battery.
