Hi,
after flashing CM12.1 with the appropriate kernel (http://crewrktablets.arctablet.com/?p=5617) I have these broken graphics as seen on the photos. Looks like the graphics memory isn't addressed correctly. Graphics memory doesn't get cleared, the screen is like shifted to the right and some aread are flickering.
I tried to flash the stock kernel even in maskrom flash mode.
The board says it's a U30GT2_RK3188 V04 from 2013.03.13 with 2x8gb memory.
Any idea how to fix that?

There are different revisions of the tab. Here are the kernel:

Maybe you have luck.
If the tab has 16 GB you can stay with the given parameter. Make sure you execute eraseIDB. In CWM install the model fix.

Hey, thank you for the quick response!
I tried all 4 kernels but none of them fixed that problem. As the graphic errors also occur on boot screen and in CWM I think it's not a kernel problem but something on a lower level. But it appeared after flashing so I wonder how this could happen.

Out tabs are getting old. Flash back a stock firmware to check if this is a hardware driven issue.

KK comes with gen2 loader, which is not compatible with gen1 loader (larger hidden write space at the end of the NAND).
To safe change to loader use this tool: http://crewrktablets.arctablet.com/?wpfb_dl=1631
