: If you are using a clone, never update the software through the official Ross-Tech pop-up, as this will immediately revoke your license again.
When your computer connects to the internet, or when you update to a newer version of the VCDS software, the program runs a security check. If the software flags your cable's serial number as blacklisted or counterfeit, it writes data back to your cable, wiping or corrupting the internal EEPROM. This effectively "bricks" the device, changing its device ID and causing Windows to reject it.
Some advanced users recover revoked cables by reflashing the interface's internal EEPROM using tools like VAGCOM_EEWriteLang.exe to reset deactivated states. :

If you have a genuine HEX-V2 or HEX-NET interface, you can often "un-revoke" the license by forcing a fresh firmware update through the Ross-Tech VCI Config Utility : Connect your interface to your PC via USB.

. This status often occurs when the software detects a non-genuine "clone" cable or when a genuine cable's internal data has been corrupted. Common Causes for Revocation Non-Genuine Cables
Many third-party cables require a specific "Loader" application to bypass license checks.
Unplug the USB cable, plug it back in, and scan again to ensure the device shows the new, unrevoked serial number. Method 2: Downgrading and Sandboxing the Software
If a clone cable is exposed to an official software update, the VCDS software often writes data to the cable's chip to intentionally disable it or flag the software license as permanently "Revoked." Step-by-Step Fixes for a Revoked VCDS License This effectively "bricks" the device, changing its device
To fix the issue permanently, you must first understand what caused it.
: For genuine users, a failed or interrupted firmware update can trigger a revocation or an "Interface Not Found" error. This often happens if the USB cable is unplugged during an update or if the computer loses its internet connection mid-process.
Once you have your genuine setup working, follow these rules to avoid spurious revocations:
If you purchased a cheap cable from a third-party marketplace and it worked for a while before being "Revoked," it is likely a clone. Ross-Tech actively protects its intellectual property; when a clone cable connects to the internet while VCDS is open, the software often "bricks" or revokes the license on that cable.
