Pandora battery - unbrick your PSP
The “Pandora’s Battery” as they call it, is just a regular PSP Battery . The battery of a psp has flash memory on it with boot information for the system. When converting the battery for this downgrade procedure, the psp program that you use actually dumps the batteries flash and puts a bin image with official sony firmware 1.50 and some developer code. When you place the converted battery into the psp it boots and runs the developer code and downgrades the psp. At this point, they say that the battery is useless. They have come out with an update that will convert the battery back and thats why they dump the flash first. After the psp is downgraded, if you use the converted “pandora battery” as your power source, it will only run a partial of the 1.50 firmware because of the missing battery flash files. in order to have full 1.50 you must convert your battery back into a normal one.
The reason a PSP running 1.50 or custom firmware is required to create a pandora’s battery is that you have to run some unsigned (i.e. homebrew) programs from the PSP itself to create the battery. Also, a memory stick pro duo is also required. Most people are suggesting to use a 256MB one, as it is the smallest pro duo you can get, plus it’s guaranteed to work on one that small. You can’t create a ‘jigstick’ (that’s what they call the memory stick that works with the battery) out of a 4GB or larger one. A jigstick will work as a normal memory stick, but you have to have a jigstick to use the pandora’s battery. Creating the jigstick is part of the process of creating the battery in the first place, so if you get a spare battery, a 256mb-2gb memory stick pro duo, and have access to a 1.5 or custom firmware PSP, just follow the instructions and you’re set.
