Connect these pads to the ST-Link V2 using fine copper wire or test clips.
Starting with VCDS version 21.9 and heavily enforced in , Ross-Tech implemented a detection routine:
Most VCDS clones act as a hardware "dongle," containing the license within their internal memory. Version clones are typically built with either an Atmega162 (older architecture) or an STM32 chip (true HEX-V2 architecture). When a clone is detected as unofficial, the software may write "junk" data to the EEPROM, deactivating the cable. Common Repair Methods
Depending on your hardware version, there are two primary ways to restore a non-functional cable: 1. Software-Based Reflashing (STM32 Chips) vcds 2231 hex v2 clone repair
Before any flash, backup the original EEPROM data. This contains your clone’s unique license.
When the official VCDS software detects a clone with blacklisted serial numbers or modified firmware, it triggers an erase command. This results in common symptoms such as: "Interface Not Found" errors in VCDS.
Modern Windows Defender or antivirus software often flags the clone loader as a false positive and deletes it . Disable your antivirus and reinstall the loader Clean Reinstall: Uninstall all VCDS versions. Delete the Reinstall 22.3.1 and copy the VCDSLoader.exe into the installation directory cdn.prod.website-files.com Run VCDS through the loader only cdn.prod.website-files.com Hardware Repair (Flashing the Chip) Connect these pads to the ST-Link V2 using
Block VCDS.exe and its loaders completely in Windows Advanced Firewall for both Inbound and Outbound rules.
Link the ST-Link V2 programmer to the newly soldered pins on your HEX-V2 PCB using your Dupont wires. Match the pins exactly: SWDIO on ST-Link ➡️ SWDIO on PCB SWCLK on ST-Link ➡️ SWCLK on PCB GND on ST-Link ➡️ GND on PCB 3.3V on ST-Link ➡️ 3.3V on PCB
Solder a row of pin headers to these pads so you can easily connect your jumper wires. Step 3: Connect the ST-Link V2 to the PCB When a clone is detected as unofficial, the
