Things You'll Need
Instructions
Turn on your PSP and connect it to your computer. Back up all of your data by right-clicking your PSP drive in your computer and selecting "Copy." Paste the contents onto your desktop for easy access.
Extract the Pandora installer by right-clicking it and selecting "Extract." Copy the "pan3xx" folder you find in the extracted files and paste it into your PSP memory stick at X:/PSP/GAME. This means open the PSP memory stick on your computer and open the "PSP" folder and then open the "GAME" folder. Place the "pan3xx" folder in there.
Rename the Sony 1.50 update from "EBOOT.PBP" to "UPDATE.PBP." Copy this into the PSP memory stick at X:/. This means you need to open your PSP memory stick on your computer and paste the "UPDATE.PBP" into the first place that comes up. This is called the root of the memory stick.
Disconnect the PSP from the computer and navigate to the PSP game menu and select the "Pandora Installer for 3.XX." This will be the first option on your PSP game menu. The program home screen will appear, and you will need to press the R trigger + X button to repartition your memory stick. This will erase all of the data on your memory stick, which is why you backed up all of the data onto your computer. On the next screen, press both the L and R triggers+X button to confirm the choice. Your PSP will reboot on its own.
Reconnect the PSP to your computer and recopy both of the files you copied over in steps 2 and 3. Place them back in the exact same spot as you did before. Once you have copied them over, disconnect the PSP from the computer and start the program once again on your PSP. Press the X button to create the magic memory stick from the 1.50 Sony update. The PSP will reboot again.
Restart the program once more and press the O button to create a Pandora battery. Once that is finished, you will be brought back to the Pandora installer program. Here press the L trigger+X button to complete the process and install the MSIPL onto your memory stick. You can now use your Pandora battery to fix your PSP easily and quickly.
