You have no selinux kernel. So there is no chance of a working gen2 loader build.

CM11 build is still in early beta stage.

Hi Oma excuse me can you help me again ? thank you in advance!!!!

I was experiencing screen tearing issues with HDMI with your v2.3 kitkat for the chuwi v88...only when i used hdmi and sometimes without using it....

so i tried the v2.2 kitkat rom for the chuwi v88 ....flashed it and the hdmi is perfect without tearing ...also everything is really smooth 

The hw decoding of videos in portrait wasn't working ...

but i managed to make it work modifying the build.prop line value "sys.hwc.compose_policy=" from "6" to "0" ....now even if i detach the video (i click on the little paper plane icon in the stock player) with the stock player everything works and the video is showing (with the 2.3 it was showing only a black window). it's more stable and smooth  compared to the v2.3 rom

 

Now i want to ask you why this is happening ?it's related to the mali driver?

if it's related to the mali driver  can you create a kitkat build based on the v2.3 rom but with the graphics drivers from the v2.2 and all the fixes for this tab? it would be really great!

 

What it's working now =

1)Hdmi (with audio) without any issues or screen tearing

2)Wifi and Bluetooth

3)Front Camera and Rear Camera

4)Touchscreen

5)Hw decoding of videos in portrait and landscape

6)Games performace is really great...real racing 3 is more smooth compared to the v2.3 rom

 

The problems that i have now with the v2.2 are =

1)Settings menu layout isn't perfect like in the v2.3 rom (see below...the text of many entries is covered) and it's not smooth in portrait...Can be fixed?

2)No battery use statistics (they are working in v2.3 rom) Can be fixed?

 

PS= to make bluetooth and wifi work 

1) i modified your fix for the chuwi  (changed the build.prop with the one from v2.2 rom and added "libhardware_legacy.so" from odys iron v1.1 rom)

2)used the boot.img of v.1.1 Odys Iron Rom. 

PS=I also changed the value in the build.prop of "ro.sf.hwrotation=" from "180" to "0" to fix screen orientation

A Little update : 

the hw decoding in portrait starts to work also on the old odys iron v.1.1 kitkat rom if i modify the build.prop line value "sys.hwc.compose_policy=" from "6" to "0"

Probably an issue with the frame buffer handling of your kernel.

Works fine on all my tabs. You can change orientation in MX-Player by using the rotate symbol.

hi Oma thanks for the reply !!!!!

i know that i can rotate the video in mxplayer but in that post i was asking another thing :

 

Since the gpu of my tablet is working perfect with no problems only on the v2.2 kitkat rom of chuwi v88 (hdmi is perfect,hw decoding works great, etc..etc..)

 

I was asking if it's possibile to rebuild the v2.3 rom including the gpu binaries from the v2.2

 

because the v2.3 has better app compatibility on play store ,the mounting solution used is better than the unified storage, the settings menù is showing right , the battery statistics works..etc..

 

PS= i made a fix to install in recovery with "hwcomposer.rk30board.so" and mali modules from v2.2 rom ...but after i install it the v2.3 rom won't boot anymore

ok deleted the hwcomposer file ..i'm on v2.3 rom ...the screen tearing in hdmi is reduced but it's still there and now the hdmi works only on 720p

i have the screen tearing issue in Omnirom build , Cm11 build , Odys Iron v1.2 , Chuwi v2.3

...but i have a perfect output only in chuwi v2.2 and Odys Iron v.1.1 build(i've tested the last one yesterday)...so something has changed in new roms

 

 i can't figure out why...if the binaries are the same ...probably it's something about build.prop or boot.img??

Little Update =

tried different kernels on v2.3 rom =

1)Mediacom Stock = Same Issue ...hdmi screen tearing

2)Mediacom feng #28 preempt 05.09.2013 = Same Issue

3)Prestigio Stock = Same Issue

4)Last Prestigio kernel ...from 1.0.12 rom = Same Issue

i give up... i'll probably return to chuwi v.2.2 rom . if you can find a solution to that issue it will be great .

anyway

thank you for all the help and the work you've done !!!!
