Hi Irina, please see my updates to your Bugzilla comments.
In the directions for generating the firmware file I did not understand this:
"set Config_Fresh to 1 and generate the binary config firmware image"
Where is Config_Fresh set?  Do I set it to 1 at the top of the shell script?...
https://github.com/blocksonic/gt9xx/blob/device-tree/goodix-generate-fw.sh

Also, your comment was not clear to me...
"You might need to revert the patch that enables reset for the Chuwi tablet [3]"
Under what conditions do I need to move these changes?

The user is reporting the following dmesg output with your latest code...
