PSP Hacks

In the fall of 2007, a team of hackers released Pandora’s Battery, one of the greatest PSP hacks in the product’s history. This software allows any PSP to be downgraded or revived from a ‘bricked’ state. Pandora’s Battery is a Memory Stick Pro Duo coupled with a modified PSP battery, and allows any PSP to run 1.50 homebrew apps.
The Pandora’s Battery project was first started under the Prometheus banner, and was worked on by hackers from the groups Noobz, C+D among others. To create the unbriker capabilites of the project, they first had to reverse engineer the service mode. This was no small feat. Next, they had to find a way to modify the PSP battery so that it could trigger this service mode. This involved careful manipulation of the battery’s EPROM. Finally, they had to innovate a method to allowed the unsigned code to be recognized as being authentic. At no time during its development did Pandora Battery’s hackers have access to official PSP developer documentation or hardware. Their achievement ranks as one of the cleverist PSP hacks to be seen on the handheld thus far.
Unfortunately, during development, a portion of the unfinished source code for the unbricker was leaked, resulting in various commercial devices using the code, marketed in expensive products. PSP owners earger to find a way to hack their console back to an unbriked state bought these devices. The PSP hacks community responded by releasing the hack for free, and ever since, Pandora’s Battery has been one of the greatest contributions to the PSP hacking scene.

PSP JigKick Battery Hacks

A JigKick Battery is an innovation that can unlock the service mode of a PSP, allowing a hacker to downgrade any PSP including the PSP Slim. In addition, it can fix any PSP that is currently in a bricked state, thus it is known as a universal unbriker. A JigKick Battery is created when the EEPROM chip on the battery is manipulated in such a way that the PSP receives a message to go into service mode.
