Finally i unistalled every driver, and my chuwi became a fanastic notebook without touchscreen.
Have you got tips or solution,i contacted the europe support but it’s been two days without answers,

Hi. I had same problem that my ubook pro 8100y became a fanastic notebook.Then finally I fixed it.

In my case, I noticed that IC version displayed on the tool(GTPV4.6.7.0-20180420) was old, it was 00_03_03.
The tool has the feature to update firmware, you can find in [Tool -> TP IC Firmware Update]. There are also newer firmware named ‘GT7385P_01.03.60(51D5)_WinDef.bin’, it can be used.

I think this operation should be written in the document, but it was not.

Can you explain the procedure to solve the problem better? I also have this problem and also for me the update to use hipen h6 from 00.03.03

You can update the firmware from here.
