I’ve formatted the tablet and reinstalled the drivers (audio etc) but the touchscreen doesn’t work. Now I am using the tablet with the keyboard. I tried to download the touch driver and to copy it into windows/INF but it doesn’t work yet
After you download and unzip/unrar the driver files from Chewi, just remember that location.
Now just go into device manage and click to upgrade each device/driver that didn’t get identified by Windows previously. Repeat until all devices are installed.
I believe by the time you finish all of them, one of the updates will have been the touchscreen itself.
