Android on the W101SA23T1, part 2

[Jordan Anderson]

So I successfully got Android 7.1 rc2 and Windows to dual boot using Grub2Win, and it's pretty snappy in terms of performance. However some things work and some don't. I have here the devices as reported to Device Manager in Windows:

Working:

Keyboard and Trackpad

Realtek RTL8723BS, WiFi and Bluetooth

Kionix KXCJ9-3 accelerometer works, but it goes in landscape when I rotate the tablet in portrait

SD Card shows up(Intel SD Host controller)

Intel USB 3.0 port(eXtensible host controller) works

Battery works as usual(drains and charges)

Intel HD Graphics, brightness works

Doesn't work:

Goodix touchscreen GDIX1002

Intel AVStream front and back cameras OV2680

Intel SST Audio device(WDM)

However I've tried editing the drivers (deice-name-here.c) in the kernel using a file manager with a built-in root browser, in this case I'm using ES File manager, free from the Play Store, and somehow after editing goodix.c(adding entries after GDIX1001 ones) so I can get the touchscreen working,(which was my first thing to do)and restarting the tablet it still didn't work and now the other files' extensions have been renamed to '.ko'. What did I do wrong? Am I in the wrong directory where the driver files are supposed to be? 

Please be advised this is only my experience in kernel hacking and I'm not sure what happened.

Initially I was thinking there has gotta be one way to fix it, and that was that I will have to re-install Android and start the process over.

The GDIX1002 touchscreen uses Serial i2c and I think it is controlled via PS/2...

This is the same error my Android install threw while bootloading. My tablet doesn't have a PS/2 port nor a controller chip. Like I said before it uses UEFI 64bit

How do I make that error go away since it's not supposed to detect the PS/2 port?

If you do find a solution for the GDIX1002 touchscreen, please post it.
My wife has a Chuwi Hi13 tablet (second production batch) which has that same damned touchscreen, and suffers from the same issue.

You need to compile a new kernel with the GDIX1002 IDs in goodix.c

How the hell do I do that? Did you know the Cambio has the same touchscreen too?
