September 1, 2010 // 6:20 am - Update #2: B1oH4z has shared a PSGroove AVR-USB-162 hex code that was compiled with a setting of 8mhz and using it Jasmin05 has confirmed the Olimex AT90USB162 works 100% now with a video below!

Update: martenbroadclk has now shared pre-compiled hex codes ready to burn followed shortly by hex codes for all boards, including both the original PSGroove release and CJPC's dev_bdvd patched version and Xantra has released the ATmega164PA PS JailBreak Schematics And PCB Layout.

Recently we reported that the PS JailBreak PS3 modchip was successfully cloned, and today the PSGroove PS3 exploit arrives!

PSGroove is an open-source reimplementation of the PSJailBreak exploit for AT90USB and related microcontrollers.

The PSGroove for now allows the very same features as the PSJailBreak but without backup manager support, you can also now remove the dongle.

The original PSJailbreak dongle had a patch that would trigger the lv1 panic hypercall if the dongle wasn't in the list of connected devices.

CJPC has also detailed HERE how to patch it to allow for the proper mountpoint dev_bdvd to be mounted enabling the playback of backup games and posted a patched version below for those lazy.

Download: PSGroove PS JailBreak PS3 Exploit / PSGroove PS JailBreak PS3 Exploit [Mirror] / PSGroove PS JailBreak PS3 Exploit (Patched) / PSGroove PS JailBreak PS3 Exploit Hex Codes (AT90USBKEY boards) / PSGroove PS JailBreak PS3 Exploit Hex Codes (All Boards) / PS JailBreak Schematics And PCB Layout

It should work on:

• AT90USB162
• AT90USB646
• AT90USB647
• AT90USB1286
• AT90USB1287
• ... and maybe more.


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

git clone git://
cd psgroove
git submodule init
git submodule update


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
F_CLOCK = 16000000

Teensy++ 1.0:
MCU = at90usb646
F_CLOCK = 16000000

Teensy 2.0:
MCU = atmega32u4
F_CLOCK = 16000000

Teensy++ 2.0:
MCU = at90usb1286
F_CLOCK = 16000000

MCU = at90usb1287
F_CLOCK = 8000000

AVROpendous v1.1:
MCU = at90usb162
BOARD = USER (need to manually attribute LED pins in Board/LEDs.h)
F_CLOCK = 8000000

MCU = at90usb1287
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 the exploit works.


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

make clean


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.


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 the exploit worked! You can see the new "Install Package Files" menu option in the game menu.


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

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.

Wasn't an update announced for PSgroove to work on all firmwares before 3.41 as well? When is the expected release date for it?

I got my tweeny ++ today, loaded the tweeny loader and installed the psgroove.hex that i had already, and when i turned on my ps3 (3.41) the light flashed briefly and then the ps3 said unknown usb device.

I teied it again with the file b1oh4z posted, the tweeny led stays orange, the ps3 recognizes the device, but i still do not get an option to load files under game tab

can anybody tell me what i may be doing wrong?

power off, plug in tweeny ++, power on, press power and quickly eject, tweeny stays orange, no option

Yup. I turned off the power save mode for the PS3. That did the trick.

On a side note, now none of backups will work. They are games that are confirmed working. When I select them to play from Backup Manager, the screens goes black and then goes back to the PS3 dashboard... ugh...

Forget it. I'm retarded. It all works perfectly now.
