The purpose of making a pandora battery is to avoid the PSP’s normal boot sequence, to make the PSP be in service mode by reading special files on the memory stick. By analogy, it’s like when we have a cd in the PC and it starts not from the hard drive but from a CD.
There are two ways of making a pandora battery: one way is by hardware, so you have to open the battery and cut a pin. The other way is by software, this is, the eeprom is modified to send a special sequence to the PSP to make it put in service mode. You will use the software method.
I’ve tested several programs to make the pandora battery, among are UltraPandora Installer 4, Hellcat’s Recovery Flasher, and OS Pandora Battery Tool. I suggest to use the latter. So here is the steps:
- Download OS Open Pandora Battery Tool 0.52.
- Extract it. It will make a directory named ospbt_052. You have to copy that folder on the MS, into /PSP/GAME folder, so you will have the following directory: /PSP/GAME/ospbt_052.
- Go to Game menu and run the applications as is shown on the video.
- In the application select Convert to service mode (aka: pandora’s battery).
NOTE: I recommend to backup the eeprom before converting the battery to pandora just in case, but I’ve never had any issues with the process of making the pandora battery.
