Always launch the software using the specific modified executable ( VCDSLoader.exe ) provided by your hardware vendor, rather than the standard desktop shortcut.
Method 1: The Complete Software Rollback & Driver Reinstallation
Carefully unscrew the plastic casing of your VCDS cable to expose the circuit board. vcds revoked fix
This issue typically occurs when a clone or counterfeit hex-USB cable interacts with official software updates, or when genuine hardware experiences an activation glitch. When Ross-Tech software detects an unauthorized serial number, it alters the firmware on the cable’s internal chip (often an FTDI or ATMEGA chip), rendering the hardware unusable.
The official Ross-Tech software connects to the internet or uses its internal database to overwrite the counterfeit chip's serial number, erasing its firmware and rendering the cable useless ("bricked"). Method 1: The EEPROM Re-Flashing Fix (For Advanced Users) Always launch the software using the specific modified
This issue is incredibly common. It usually happens when an aftermarket, clone, or modified hex-cable interacts with an official software update from Ross-Tech. When the official VCDS software detects a non-genuine hardware serial number, it automatically deactivates or "blocks" the cable's internal EEPROM firmware.
Is your cable an or an aftermarket clone? It usually happens when an aftermarket, clone, or
: Plug the interface into a vehicle's OBD-II port (this provides 12V power) and run a Test in the Options menu to confirm status. 3. Fixing a Clone Cable (Blocked/Revoked)
If your genuine interface has lost its connection, you can often restore it by forcing a firmware update through the VCI configuration utility:
: Disconnect your laptop from the internet and disable Windows Defender/Antivirus, as they often delete the "loader" files required for clones.
