Irina, I just saw this after updating the Bug 156511 with Serg's info.
He says he just used the following single patch to generate the Chuwi
Hi12 firmware file and get it working using
ubuntu-16.10-beta2-desktop-amd64.iso:

Subject: Re: Goodix touchscreen works intermittently, fails reading config info.

Irina, a little more info on the symptoms. The user reports the
touchscreen works when restarting but fails when powering on.  He says
pretty much 100% of the time.  The log is the same...

Hi Brad,

Thanks for all the information you provided. I have already replied on the
Bugzilla thread with some patches that enable reset for the device.

Regards,
Irina
