Things You'll Need
Instructions
Turn off the Sony PSP and remove the battery and memory stick from the device. The battery port is located on the rear of the device, while the memory stick reader is on the side of the PSP.
Insert your Magic memory stick into the PSP memory stick reader. This memory stick has the modded firmware located on it. Insert the Pandora battery to the PSP and your PSP will turn on by itself and go into service mode.
Press the "X" button two times to install the modded firmware on your PSP 2000. Wait as the custom firmware is installed, and press the "X" button once more to shut down the PSP after the installer finishes.
Remove the Magic memory stick and Pandora battery from the PSP and replace them with the normal ones you previously removed in Step 1. Turn on your PSP 2000 and you will be running modded firmware.
