yes if you do this
If you only have one battery and want to unbrick/downgrade 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.

what firmware is the psp you,re gonna use to make the battery

Alright, someone correct me if I'm wrong, I'm not new to the PSP homebrew scene, but I am new to this Pandora's Battery concept.

From what I understand, basically you need to find someone who has a homebrew PSP, they can then turn their battery (or yours) into a Pandora battery, along with a file on the memory stick.

You then insert the Pandora Battery into your PSP along with the memory stick and it will act as a unbricking program that will uninstall/install 1.5 on your PSP.

Then you can turn the Pandora Battery back into a normal battery and get rid of the file on the memory stick, and voila. You have 1.5 and the homebrew person is as good as before. Right? I'm going to be trying this today to help out a friend who's buying a PSP.

If you had read properly you need a PSP running custom firmware or 1.50 to create the files.
