Hi, i'm having problems with brightness controller, inverted touchscreen and externalsd (micro sd card) on my RK3066 GoClever Tab R974.2. About brightness controller i can't set lower or higher brightness for my display. About inverted touchscreen ... if i set hwrotation to 180 the rotation of sensors works correctly but the touchscreen is now inverted. After 2-5 reboots my tablet can read externalsd (micro sd card). How can i fix this bugs? ... i must recompile kernel or copy all lib folder from original rom for my tab?.

Do not use build.prop commands as they will not work in the CM10.1 build.

Try to use one of the sensor fixes: http://forum.xda-developers.com/showpost.php?p=46833527&postcount=665

Brightness is most likely a problem of the stock kernel. Can you pls upload your stock boot.img?

Only sensor "build in" cm10.1 works correctly on my tablet but rest sensors has problem with changing screen position and touchscreen is inverted/reverted:|. Stock boot.img in attachmets. Download boot.zip

----------------------------------------

I made the short video to show you what i mean saying "Touchscreen is inverted"(video in attachmets).

Is this the genuine kernel running?

I am of the opinion, we managed to run the build on xda. No reverted touch.

That's why I am asking if you run the genuine R947.2 kernel. Or is it a Teclast one?

The dmesg log indicates that there is/was a strange kernel which re-flashed the touch-controller firmware.

Hello.

I also have one. You should use one of the fixes. There are two with almost same name (diffrent in "sensitive 300"). You need fix without "sensitive 300". After that you see correct display orientation but cameras will be upside-down.
