Perform a "Full Chip Erase" to remove the corrupted/blocked firmware.

Updating the VCDS software to a newer version corrupts the mismatched firmware on the clone's microcontroller.

on ST-Link (Note: Do not plug the interface into your car or a computer USB port while using the programmer's power pin). Step 4: Clear the Bricked Firmware Plug the ST-Link V2 into your computer's USB port. Open the ST-LINK Utility software. Click on Target →right arrow

Specialized patch software that acts as a buffer between the clone hardware and the VCDS software, preventing future bricking.

These small 8-pin ICs handle K-Line communication. If VCDS connects to newer CAN-bus cars but fails on older K-Line vehicles, replace these chips.

Before initiating software or hardware repairs, identify your clone's primary processor chip by opening the plastic casing. Clones generally utilize either an or an STM32 processor . Step 1: Software Repair via VCDSLoader

The only exception is if you have rare firmware (e.g., a clone that works with VCDS 23.x). In that case, repair is worthwhile because replacement clones are increasingly locked down.
