- Insert Memory Stick into the PSP
- Remove power cord and insert the JigKick Battery into the PSP.
- A menu appears when the PSP boots. Follow the onscreen information
and instructions.
- Choose the option to downgrade to 1.5!
- That's it! you're done!
Quick guide to converting your battery
If you only have one battery and want to unbrick your PSP, you can.
1) Convert your battery into a jigkick one using "Pandora's Battery Creator", but before you press X, press TRIANGLE to backup your battery's EEPROM to ms0:/eeprom.bin
2) Unbrick your PSP as normal
3) When you are done unbricking, take out the battery and the magic memory stick. Start up the PSP using the AC adaptor (do not try to use a USB charger, it will not start up)
4) Insert the magic memory stick and the magic battery
5) Run "Pandora's Battery Creator" again
6) Press L+R to restore the ms0:/eeprom.bin to your battery
NOTE: You can also restore a battery without having made a backup, by pressing SQUARE at step 6. This will generate a fake serial for your battery (0x12345678) which allows it to work normally, but there could be side-effects.

This will generate a fake serial for your battery (0x12345678) which allows it to work normally,
(but there could be side-effects like randomly reflashing you psp)

1. turn on the psp fat using the AC adaptor
2. insert the stick and the battery
3. run pandora's creator
4. press L+R then choose restore backup
is this right? thank you
Just launch the Pandora Battery Creator and select the option Make normal battery.
This will write a new serial number to the battery.
