This guide details the process of upgrading a Chinese VCDS cable to the latest Russian version (VCDS 12.12.0 RUS для китайского шнурка). This process involves using a USBASP programmer and requires careful attention to detail.
The initial attempt to upgrade the cable, which was built on an Atmega162 chip, resulted in a bricked device. The issue stemmed from a failed firmware update that rendered the cable inoperable.
After several unsuccessful attempts and troubleshooting, including verifying soldering connections and reflashing the firmware, the solution was found in reprogramming the FTDI chip responsible for USB communication.
The process involved using specialized software to correctly identify and update the FTDI chip. This step proved crucial in restoring the cable’s functionality and allowing it to communicate with the diagnostic software.
Initially, the cable was recognized as an older version (1.95). However, the VCDS software prompted an update to version 1.96, which successfully completed, resulting in a fully functional cable with the latest Russian language pack. This update enabled full compatibility with current vehicle models and diagnostic software.
This successful upgrade highlights the importance of correctly identifying the hardware components, specifically the Atmega162 and FTDI chips, and utilizing the appropriate software and procedures for flashing the firmware and updating the drivers. The process requires patience, persistence, and a thorough understanding of the hardware and software involved.
This detailed guide, along with the assistance of a knowledgeable expert, demonstrates that upgrading a Chinese VCDS cable is possible, even after encountering significant obstacles. The key takeaway is the importance of persistence and seeking expert advice when facing challenges.
