PSGrade

This is PSGrade, an open-source reimplementation of the psjailbreak service jig for AT90USB and related microcontrollers, based in part on psgroove.

It is known to work on:

• AT90USB162
• AT90USB646
• AT90USB647
• AT90USB1286
• AT90USB1287
• ATMEGA32U2
• ATMEGA32U4

... and maybe more.

Cloning

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

git clone git://github.com/zAxis/PSGrade.git
cd PSGrade

Configuring

Edit Makefile to reflect the dongle being used. Alternately, you can just use the "build_hex.sh" to automatically build hex files for all supported boards.

Building

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

To make hex files for all supported dongles:

./build_hex.sh

To make a single hex file for a dongle configured in the Makefile:

make

Using

To use the service jig:

• Hard power cycle the PS3 (using the switch in back, or unplug it)

• Plug the downgrade dongle into the PS3

• Press the PS3 power button, followed by disc eject

• Once the playstation has booted, look at the firmware version

• Shutdown the playstation

• Remove the dongle

• Power on the playstation, verify the playstation is now in service mode

• Shutdown the playstation

• Locate the necessary lv2diag.self (stage 1) and PS3UPDAT.PUP

• Put both files in the root (not in a sub-directory) of a freshly formatted USB flash drive (it is important there are NO other files on the USB flash drive)

• Plug the USB flash drive into the USB port closest to the Blu-Ray drive

• Power on the playstation

• There will not be any activity on the screen, the USB flash drive access LED will blink

• Once the downgrade has completed, the playstation will shutdown

• Remove the USB Flash drive

• Power on the playstation, verify the playstation is still in service mode

• Check the firmware version in system settings

• Verify the downgrade was successful

• Shutdown the playstation

• Locate the necessary lv2diag.self (stage 2)

• Put the file in the root (not a sub-directory) of a freshly formatted USB flash drive

• As before, plug the USB flash drive into the USB port closest the Blu-Ray drive

• Power on the playstation, the lv2diag will disable service mode and shutdown the playstation

• Remove the USB flash drive once the playstation is shutdown

• Turn off the power or unplug the playstation

• Turn on the power / plug in the playstation

• Once the playstation has booted, verify it is no longer in service mode

• Verify the firmware version in the system settings

Thanks (in no particular order)
