Ok, looks good. Tab has Atheros wifi.

Try this build: http://www.arctablet.com/blog/forum/crewrktablets-rk3026-entwicklung-und-customroms-development-and-croms/rom-cube-u25gt2-h-android-4-2-2-custom-root-firmware-20140622/

Kernel: http://crewrktablets.arctablet.com/?wpfb_dl=2508

Just change the kernel in folder rockdev/Images and uncheck the loader before flash.

Every tab has it's own kernel (hardware abstraction layer). So, do not flash a strange firmware/kernel into the tab without having at least a backup of the kernel. Pls contact the retailer for the genuine firmware.

Hello Oma7144 and everyone else. Good job for all your work!

 

So, I have a rockchip tablet too. It's a 3026 and the model is m07r6. (It's sold as Turbo-X Rubik 7'' here in Greece.)

 

I install the 4.2.2 firmware and I replace the kernel.img with the one provided for m07r6 on the 2nd post. 

It boots normally, but I have 2 problems:

1. Orientation is not working at all. 

2. The touch is partially working. I touch the left side of the screen and the tablet feels like I'm touching the right side of the screen. When I touch the right side of the screen nothing happens. The same happens when I use TWRP.

Could you please help me?

 

ps. I cannot find the original firmware anywhere. Also, I didn't make a backup before flashing your custom rom. (my bad)

The build is done for ROVERPAD SKY C70 RSP TR7C and will also boot on tabs named R88 (thanks to oss85 for testing) - ;-)

You will find further kernel in post#2.

Every tab has it's specific kernel. Without this kernel no chance to recover the tab. Pls ask the manufacturer for a firmware link.

Doesn't work this way. A kernel (hardware abstraction layer) has to be compiled from source. So, never frash something strange into the tablet without having a fallback (stock firmware or a dump of the running firmware).

Could be a driver issue. Anyway, you can do it on the tab. Hope it is already rooted.

Open a terminal and type:

su
dmesg >/mnt/sdcard/dmesg.txt
logcat -d -v time >/mnt/sdcard/logcat.txt
cat proc/cmdline >/mnt/sdcard/cmdline.txt
cat proc/mtd > /mnt/sdcard/mtd.txt
dd if=/dev/mtd/mtd1 of=/sdcard/kernel.img bs=4096
dd if=/dev/mtd/mtd2 of=/sdcard/boot.img bs=4096
dd if=/dev/mtd/mtd3 of=/sdcard/recovery.img bs=4096
dd if=/dev/mtd/mtd9 of=/sdcard/system.img bs=4096
