If your interface lights are flashing red or it is not found during a lead test, you may need to force a firmware reset.
Right-click the device properties in FT_Prog and change the Vendor ID to 0403 and Product ID to FA20 (standard VAG-COM values).
Plug the cable into a different USB port (preferably a USB 2.0 port rather than USB 3.0, as older HEX-NET or HEX-USB+CAN interfaces sometimes prefer older USB architecture).
Disable Internet for Clones: If you must use older hardware, ensure your laptop is offline whenever the software is running. vcds revoked fix
: Clones typically require a specific VCDSLoader.exe file.
Rarely, aggressive antivirus (Norton, McAfee) or a Windows update will block VCDS from "phoning home." The software then assumes the lack of response means you are using a clone, so it self-revokes.
If you are using a clone, never update the VCDS software to the latest version, as this often triggers the revocation. If your interface lights are flashing red or
If your clone cable is revoked, it is often "bricked" at the hardware level. Some community-sourced methods may work to reactivate it:
: If you have a genuine interface, you may need to pay a registration fee to Ross-Tech to transfer technical support rights and reactivate the full license for a new owner.

Some users on community forums like Reddit's CarHacking or TDIClub suggest adding pull-up resistors or capacitors to the circuit if the hardware was damaged during the "revoke" signal. Prevention Checklist Never Update: Ignore all prompts to update the software.
), though this is increasingly blocked in newer firmware versions. EEPROM Flashing
: Ensure the cable is fully "snapped" into the car's OBD port. It often requires more force than expected to establish a complete connection.
Fixing a revoked license can be a tedious process. Follow these strict operational habits to ensure your diagnostic setup remains active permanently:
