This is a compiled version of PSGroove with Backup patch, an open-source reimplementation of the psjailbreak exploit for AT90USB and related microcontrollers courtesy of Mathieulh and his team.



But before you proceed folks, make sure you know excatly what you are doing as this is totally a do-it-yourself method. You'll also need to purchase a small board, either the Teensy++ USB Development Board or AT90USBKEY, to jailbreak your console although some reports now claim that the code can also be ported to the PSP and TI-84 Plus Calculator.

It should work on:

AT90USB162
AT90USB646
AT90USB647
AT90USB1286
AT90USB1287
ATMEGA32U4
… and maybe more.

This software is not intended to enable piracy, and such features have been disabled. This software is intended to allow the execution of unsigned third-party apps and games on the PS3.


Cloning

The repository uses the LUFA library as a submodule. To clone, use something like:

git clone git://github.com/psgroove/psgroove.git
cd psgroove
git submodule init
git submodule update

Configuring

Chip and board selection can usually be handled in the Makefile. In particular, update the MCU, BOARD, and F_CPU lines. Suggested values:

Teensy 1.0:
MCU = at90usb162
BOARD = TEENSY
F_CLOCK = 16000000

Teensy++ 1.0:
MCU = at90usb646
BOARD = TEENSY
F_CLOCK = 16000000

Teensy 2.0:
MCU = atmega32u4
BOARD = TEENSY
F_CLOCK = 16000000

Teensy++ 2.0:
MCU = at90usb1286
BOARD = TEENSY
F_CLOCK = 16000000

AT90USBKEY / AT90USBKEY2:
MCU = at90usb1287
BOARD = USBKEY
F_CLOCK = 8000000

Board-specific notes

Teensy boards only have one LED, so it will turn off when the exploit succeeds rather than turn green. Older Teensy 1.0 boards also have the polarity inverted. In general, a LED should do something when the board is powered, and do something different when theexploit works.

Building

On Linux, use the AVR GCC toolchain (Debian/Ubuntu package: gcc-avr). On Windows, WinAVR should do the trick.

make clean
make

Programming

Now program psgroove.hex into your board and you're ready to go. For the AT90USBKEY and other chips with a DFU bootloader preinstalled, you can get the dfu-programmer tool, put your board in programming mode, and run

make dfu

For the Teensy boards, you probably have to use the Teensy Loader software.

Using

To use this exploit:

• Hard power cycle your PS3 (using the switch in back, or unplug it)
• Plug the dongle into your PS3.
• Press the PS3 power button, followed quickly by the eject button.

After a few seconds, the first LED on your dongle should light up. After about 5 seconds, the second LED will light up (or the LED will just go off, if you only have one). This means theexploit worked! You can see the new "Install Package Files" menu option in the game menu.

Notes

A programmed dongle won't enumerate properly on a PC, so don't worry about that.
