Unbrick PSP with “Magic” Memory Stick files and special battery

Nicodemus82 dropped by our forums and shared news of the “PSP Magic Memory Stick Files – SONY Unbricker”. Apparently, a person sent a bricked PSP to Sony. The PSP was returned with a memory stick inside with the following files:

• 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).

According to nicodemus82, the said memory stick is useless without a special battery that internet hamsters dubbed the “Sony JigKick” (After researching a bit, we found that the jigkick is actually a “special” move that targets a certain place). Reportedly, the battery accesses the third battery pin that “enables writing to the IPL from the memory stick”. Here are the JigKick’s specs:

• 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 40×120 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.

Anyway, we’ve been hearing about PSP unbrickers since the word “brick” was coined to indicate a damaged PSP so we’re taking this bit of news with more than a pinch of salt.
