Yoga 920 Critical problems after auto firmware update

Hi all,


Yesterday when I turned on the computer and logged in into windows, a warning-window poped-up asking for recomended "Firmware Update" by Lenovo. I ve proceeded with the update. After an intall-restart I wasn't able to log in with my fingerprint anymore.


After a small investigation I've realized that are now three devices with problems (Code 31) in my device manager.

The devices are:

  1. Biometric Devices - Synaptics WBDI - SGX
  2. Sensors - HID Sensor Collection V2
  3. System Devices - System Interface Foundation V2 Device

So, besides the FingerPrint, I'm not able to use the Auto-Rotate (when turning the lid into tablet or tent mode) feature and the Lenovo Vantage Software since it asks me to update the System Interface Foundation Driver.


What I have tried so far:

  1. Reinstall (since I can't rollback) the Firmware Driver: "Type C Firmware for Windows 10 (64-bit) - Yoga 920-13IKB, Yoga 920-13IKB Glass 1.3" (since there isn't a lower version to roll back)
  2. Reinstall all drivers from Lenovo web-page (FingerPrint, System Interface Foundation, Chipset, Display, Audio, etc)
  3. And finally, Reinstall the operating system Windows 10 64 using system restore


I've not clue what to do next and I'm really avoiding opening an RMA. 

Please help me.


Thank you.
