Chuwi HI8 Q32G22150803994 problem

After updating Windows to version 20H2, the touchscreen, auto-rotate and sound stopped working. Please give instructions on how to restore the tablet to work.

First of all, disable driver signature verification.

Then try to reinstall drivers.
touch
gyroscope
audio

If this does not help, then try to roll back the update and make a backup of the working drivers.

Where can I find these devices in Device Manager?

Touch - human interface devices (HID)
Gyroscope - sensors
Audio- sound, video and game controllers

Failed to reinstall drivers. Now even the mouse and keyboard are not recognized :frowning: Tell me how to reinstall Windows from the Recovery Windows menu of the tablet, so that the Android system does not suffer? Is there any step-by-step instruction and a place where you can download the image?

Most likely it won’t help.
