Sony PSP unbricking battery revealed - the JigKick!
As we should all know, Sony has a unique way of unbricking PSPs consisting of a special memory stick software as well as a special battery which is known as the 'jigkick'. The software was supposedly leaked online a few weeks back, but no one had ever seen the mighty unbricking battery before - but now images of the interesting hardware have been released! You can read about how this battery works with software to unbrick a PSP here.
Even more information on the Official Sony PSP Unbricker
New information has come to light on the Official Sony PSP unbricker. According to internet reports, a gamer sent a bricked PSP to Sony who then returned it with a Memory Stick inside and contained a slew of files. As already established the Memory Stick is useless without a special hardware battery which accesses the battery pin that enables writing the IPL from the memory stick.
Contents of returned PSP Memory Stick
- Binary encrypted full NAND image.
- Required modules for system control for use by IPL of debug hardware.
- Logging module for debug log review (log is saved after full write).
A file used for testing that the system plays well (usually a demo of a PSP game).
Special Battery hardware specifications
- 1.1v-3.5v debug unit for connecting through the serial port in 3rd. battery pin.
- Transmission of data is UNENCRYPTED but uses a XOR algorithm for transmission (easily parsed and analyzed).
- Contains any number of IPLs (different ones for each motherboard revision (TA-XXX))
- IPL is loaded into the Kernel Memory. ME area seems most likely (IPL of the PSP is the same but missing 2 essential modules that the debug unit has).
- Contains ipl_mg_modules.bin and ipl_mg_nanddriver.bin
- IPL is encrypted in 3 stages. Easily decrypted to show stages, but not for decrypt each individual stage.
- Contains a 40x120 column TFT screen for display.
- Has a SERIAL port for PC connectivity.
- Seems to have a 32MB ROM IMAGE on Flash.
- 8MB of RAM.
- Nickel-Cadmium Battery Cell (possibly 76 hour battery life).
- AC/DC adapter port 15V.
- Contains 4 buttons (on/off, reset, connect/disconnect, menu).
- Arrow keys UP and DOWN for menu.
