Some users get “Operation failed!- invalid format- Subfunction not supported ERR: 7F2112” when programming a 2008 Grand Vitara all keys lost with VVDI Key Tool Max Pro.
Solution from XhorseVVDI.com:
- Use this path: IMMO Programming -> Europe -> Grand Vitara -> 2005-2007 (or 2007-)
- Check device and vehicle communication.
- If it still fails, send the error screenshot + VIN to Xhorse for support.
Tip: Selecting the correct year range often fixes this error.
