❌ Final warning
- Do not install VCDS 24.5+ with a clone – it will permanently corrupt the FTDI/STM32 EEPROM in some designs.
- If you see “Unauthorized interface – counterfeit” – stop using that copy and revert to older software immediately.
Internet Connection: Connecting to the internet while VCDS is open often triggers an automatic license check that blacklists clone serial numbers.
