• Answer:

  You actually need more than just a pandora battery. You need a pandora battery, an empty memory stick, and another PSP capable of running homebrew. You can buy what is called a TOOL battery that will double as a Pandora battery (used to put the PSP into service mode) as well as a normal gameplay battery. The second psp is so you can make the "magic memory stick" used to load the new firmware onto the PSP. The files you get are copyrighted sony system files and therefore are illegal to distribute across the internet. I've included links to sites where you can get the TOOL battery or a device to convert your battery into a pandora and then back into a regular battery, as well as a site with info on how to do it all. You can find different prices on the batteries, but just make sure it's the bright red battery. It can be used as either a pandora battery or a normal battery with the push of a button.
