Tablet "charging" but not holding the Charge

Ok Story time,

Serial Number: Q128GH62060****

In an attempt to update the pen drivers to make the buttons configurable I installed the latest hi6 drivers from the official website posted.

This was the wrong thing to do and it was only in the user comments farther down where several users have reported the same error as there is no warning on the main post or version check within the exe.

This has made the touch screen and pen unresponsive and ghosting. Touch Screen ghosting Chuwi Hi10 X - YouTube

In my opinion the hid_i2c_update-20180419.exe has reconfigured the Hi10 x into a Ubook Pro and that may explain the touch screen issues.

In my attempt to fix these issue and under the instruction of Chuwi Support I have since reinstalled the supplied drivers several times and at one point have gotten it working. It is not working at all now. However I have also found a second issue that the battery is not charging. It had been running on the battery out the box but unable to recharge. I have included a video. Chuwi Battery Problems After Hi6 Pen Update Hi10X - YouTube

It shows as charging but is not. This could be a DOA problem in the charging circuitry.
I have purchased a new 12V 3A charger and it is still acting the same.

I have been supplied with this link http://www.mediafire.com/folder/vh5zqntzyahwf/HI10%20X and reinstalled both versions of the bios, both versions of Windows and reinstalled the drivers from both the mediafire link and the drivers found at [Double Driver] Hi10 X Fresh Install Drivers - #17 by level1imp

I have also tried to reinstall the I2C HID Driver from when I had the touchscreen working but when I noticed the battery issue I proceeded to backup the drivers and reinstall the OS, Bios and Drivers. This has not worked.

It says code 10 driver error, ACPI DSM error when I force the I2C driver (as the goodixtouch driver has never worked for me) and I believe this to be the issue potentially for the battery too some sort of ACPI DSM issue.

During the last OS install I tried the developer tests. And this was the battery test and the touchscreen test was a manual test and thus failed.

I have also had issues with reinstalling some bios versions and had issues.

At this point I feel like I have tried everything and while the device boots fine any more I do will make it worse.

Is there an easy way to fix this?

Thanks for reading - I have emailed this to support but you guys seem to know what your doing and they seem keen on me sending it back for repair at a cost.
