Hi, manupc, I install this oc kernel by arctools on kasty's v2.01 cROM. I encounter "screen flickers" when running antutu 3D test and also nenamark2.

Thanks for your feedback. i updated the kernel. Those benchmark artifacts should be fixed now.Check my post here:
http://www.arctablet.com/blog/forum/fnf-ifive-tablets/rom-manurom-ifive-x2-4-4-2-v2-0-1/#p38444
We must wait for admin to delete last oc kernel and update to this one in ArcTools.
Report in case the problem remains.

Hello,
I have just installed this rom and so far works great! Many thanks kasty!
The only problem I am facing is when I try to modify the build.prop to change the system bar (split notification bar) from top to bottom old style bar, nothing changes.
I edit the line ro.rk.systembar.tabletUI from =false to =true, however, even though the file is properly saved, there is no change after reboot...
Is this some sort of a bug or this procedure was changed in kitkat?
Thank you very much again

Hi again,
After some testing I found the following bugs:
-Auto brightness is not working
-Screen flickering/Glitches randomly, especially when apps are in full screen mode
-Cannot change the system bar mode from top to bottom (as mentioned in my previous topic)
-With stock launcher, the far right app on the shortcut bar of the home screen is always lost after reboot
Other than the above, the rom is very fast and I am very sad I have to downgrade the rom until these bugs are resolved...

The OC kernel doesn't work for me, I've used it for a few days and had one crash and one occasion in which the tablet made a factory reset when I powered it off. I was quite surprised to see that all the applications and settings were gone after I turned it on again the next day..
Without the OC kernel, I also have the problem in which the launcher tiles lose the application which is attached to the tile. Sometimes all the apps are there in the launcher, sometimes there are a few and sometimes none. I think I need to try a different launcher and see what happens.

Is it possible to flash this ROM using CWM?

It seems that now I can't downgrade this rom... When I try to install any 4.2.2 rom using Rockchip, I get a fail...
Do you have any ideas on how could I go back to 4.2.2 from 4.4.2?
Thanks

Thank you very much for your work!, ive just tested the latest rom, no problems except that after restart , shortcuts from home screen are lost. This is happening for apps that are moved to sd only.
Again thanks for your work!
