This is useful to 'cut down' an A2L file into something that's useful for tuning, and get it into a free tuning-focused UI. This should work to extract an ODX from any and all FRF flash containers as the format has not changed since it was introduced.Ī2l2xdf provides a method to extract specific definitions from A2L files and convert them to TunerPro XDF files. Other ECUs use different flash container mechanisms within ODX files.įrf provides an FRF flash container extractor. It supports the "AUDI AES" (0xA) encryption and "AUDI LZSS" (0xA) compression used in Simos ECUs, and the DQ250-MQB encryption scheme used in MQB DSGs. This script has been tested against a range of SA2 bytecodes and should be quite robust.Įxtractodx.py extracts a factory Simos12/Simos18.1/Simos18.10 ODX container to decompressed, decrypted blocks suitable for modification and re-flashing. The bytecode from the SA2 script is executed against the Security Access Seed to generate the Security Access Key. The SA2 script can be found in the ODX flash container for the vehicle. Sa2-seed-key provides an implementation of the "SA2" Programming Session Seed/Key algorithm for VW Auto Group vehicles.

All of these backends require application software patches.
VW ECU FLASH SOFTWARE 1.9 TDI PATCH
Simos_hsl.py, brought to you by Joedubs, provides a high-speed logger with support for various backends ($23 ReadMemoryByAddress, $2C DynamicallyDefineLocalIdentifier, and a proprietary $3E patch used by an aftermarket tool).
VW ECU FLASH SOFTWARE 1.9 TDI PASSWORD
TC1791_CAN_BSL and Simos18_SBOOT together form a complete "bench flashing" toolchain, including a password recovery exploit in SBOOT and a bootstrap loader with the ability to read/write/erase Flash.
It also allows unlocking and FRF extraction.
VW ECU FLASH SOFTWARE 1.9 TDI FULL
VW_Flash_GUI.py provides a WXPython GUI for "simple" flashing of "flash package" containers, full BIN files, and calibration blocks. VW_Flash.py provides a complete "port flashing" toolchain - it's a command line interface which has the capability of performing various operations, including fixing checksums for Application Software and Calibration blocks, fixing ECM2->ECM3 monitoring checksums for CAL, encrypting, compressing, and finally, flashing blocks to the ECU. There are a few file preparation tests to verify basic file extraction and patching functionality, which you can run using python3 -munittest tests/test_prepare.py Tools
VW ECU FLASH SOFTWARE 1.9 TDI CODE
Code is formatted using black - beyond this, there are limited code style and structure rules as the project is still evolving quickly. Pull Requests are welcome and appreciated.
If you don't provide these 3 files (or you take phone pictures of your screen or some other ridiculous thing), I can't help you because I don't have information about what went wrong. Troubleshootingįeel free to open a GitHub issue, but you MUST include the following 3 files if you want help:įlash.log, flash_details.log, and udsoncan.log. In this way a complete persistent trust chain bypass can be installed on a Simos18.1 ECU.ĭocs/dsg.md documents the extremely simple protections applied for the Temic DQ250 DSG. 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.
