This CBOOT will write the 'Security Keys' / 'OK Flags' for another arbitrary CBOOT regardless of signature validity, which will cause this final CBOOT to be 'promoted' to the real CBOOT position by SBOOT. SocketCAN on Linux, including MCP2517 Raspberry Pi Hats, slcan, and other interfaces.ĭocs/docs.md contains detailed documentation about the Simos18 ECU architecture, boot, trust chain, and exploit process, including an exploit chain to enable unsigned code to be injected in ASW.ĭocs/patch.md and patch.bin provide a worked example of an ASW patch which 'pivots' into an in-memory CBOOT with signature checking turned off (Sample Mode).

Supported on Windows, possible to make work on Linux/OSX. Clones and counterfeits have mixed results. Other J2534 devices are supported, but only if they support the STMIN_TX IOCTL, which many do not. Macchina A0 with BridgeLEG firmware, via both USB-Serial and Bluetooth Low Energy (BLE).Prebuilt releases for Windows are available at : ĭocs/windows.md contains detailed setup instructions to use a point and click interface called VW_Flash_GUI to create a 'virtual read' and unlock Simos18 for writing unsigned code and calibration.ĭocs/cli.md contains documentation about the command line interface VW_Flash.

RSA-bypass/'unlock' patches are provided for Simos 18.1/4/6 (SC8 project identifier) and Simos18.10 (SCG project identifier). Currently supports Continental/Siemens Simos12, Simos18.1/4/6, and Simos18.10 as used in VW AG vehicles, as well as the Temic DQ250-MQB DSG.
