All right!
In your case it seems that the resolution was for some reason different than on my Minibook, so I wouldn’t suggest using my file directly. I think the simplest way would be:
- Open the “a_JacekJagosz_original” file with the GTP tool. This is exactly the settings you gave me earlier.
- Change the filtering settings (as on the screenshot) and save it to a new file
- Use the “hid_i2c_update” tool to flash the new configuration
This is exactly what I did at the end: used your file, changed the resolution and filtering, and then uploaded it. The upside is that you don’t have to install/uninstall drivers. This worked perfectly for me, but I can’t guarantee it 
Disclaimer for anyone else brave enough to try it:
Following this could make your touchscreen or even the whole laptop useless. It involves updating data on the touchscreen controller chip, and no Windows or driver re-installations will fix it if something goes wrong.
There are two options overall:
- The GTP software, it has GUI but requires installing unsigned drivers. Another downside is that the touchscreen stops working with these drivers (until you restore them) so it’s more difficult to test.
- Use my tool to make a backup of your settings, then use Chuwi/Goodix? Tool to update the configuration. No drivers to install but it’s all command line
For the first option, download the zip file and see the powerpoint with instructions inside. It already existed, I just added some slides. The general process is
- Install drivers
- Use the tool to read your current settings and back up to file
- Make the changes in the tool, or load one of our settings from the file
- Upload the new settings to the controller
- Uninstall drivers
For option two:
- Run the HID_Dumper and copy the output to a text file. It should look like above, and have 444 bytes. To make a valid config file, you’ll have to manually copy the appropriate number of bytes from each batch (should be 60, 15 or 5) after skipping the first 5, separated by commas.
- You can try one of our files. Or, open your backup with the GTP tool (no drivers needed, just make sure to set to the 7382/5 model first), make changes as you want, and save it. This will also confirm if the config file is correct, otherwise it will give you an error.
- Run the command “hid_i2c_update-20180419.exe -d -p name_of_config.txt” This will update the configuration while printing more information about what is happening. If you see errors, you can try running it again.
I packed everything into this file. Good luck!
