Thank you for the kernel! Name is feng #24 preempt 26.06.2013 and it is now in the archive - http://crewrktablets.arctablet.com/?wpfb_dl=1790

Every coin has two sides: kernel change log of kernel feng #28 may stated: increased stability ;-)

Hi Oma i've installed the v1.2 rom for Odys Iron on the mediacom and it's working great! it's the same of the chuwi but i don't have to install the fixes :) ... i've used the stock mediacom kernel that you gave us for the chuwi rom ....and the only thing that i changed is the lcd density in the build.prop from 264 to 160 and used a modified boot.img (see below)

1)i had a problem with the tablet charging when it was off...the image of the battery charging (the white one in the boot.img) was flickering on the screen ...and it stayed on screen even after the tab booted....so i extracted the boot.img of odys-----> changed the images of battery in res/images/charger with the one of the stock 4.2.2 boot.img and changed the file "charger" with the one from the boot.img you gave us for the chuwi rom :) and now it's charging fine ..no problems with the images ...Can i use also the boot.img you gave us for the chuwi rom?? with that boot.img everything was working fine!

 

PS=I've also tried the OmniRom build you made for Odys Iron...used the mediacom kernel and changed the lcd density to 160 in the build.prop....i'ts great!!! really fast but No Wifi and Bluetooth :( and also there are problems with the video decoding (it's strange)

 

PS=for the hangouts problem

     i was having the same issue yesterday and fixed it with this steps :

     1)i log in in my google account from desktop ...clicked on security settings and then on  looked at the "Connected applications and sites" section (click on "review permissions")

     2)revocked access to all the entries i had on the list

     3)did a factory reset of the tablet

     4)When the tab booted i log in whit my google account ...stopped the updates of apps from the google store.. updated Google Play Services  (Search with the stock browser "google play services" and open the link of google play  and than select "open with Play Store") 

     5) i didn't read the fact that i had to use the google+ modified from oma ...so i've downloaded Google+ apk from AndroidPolice--->Link : GooglePlus....and installed it 

     6)Than downloaded Hangouts apk always from AndroidPolice ----> Link Hangouts and installed it

     7)After that everything was working fine !

this was the thread that give me the idea to do so http://forum.xda-developers.com/showthread.php?t=2482061&nocache=1 Post #5

Wifi driver is now back in the build. So try again: http://crewrktablets.arctablet.com/?p=3555
Install the 160dpi fix directly after the format_NAND fix.

Ok i've tried  the new build but there are some bugs and i've tried different kernel but bluetooth doesn't want to work ...

 

1)i've tried the stock mediacom kernel "feng #24 preempt 26.06.2013"... ...if i turn off wifi ...the bluetooth start to work but wifi will not turn on anymore

2)i've tried the kernel that you gave us for the chuwi "feng #28 preempt 05.09.2013" ...the wifi is always working but the bluetooth doesn't wont to turn on 

3)with all the kernels---> there are problems in video decoding ...in particular with the HD video h264 ....the images are like shifted and there is a green band on top of the video

if i play a standard definition video i don't have problems ....and if i use software decoding with hd video the images are fine but is really slow!

4)i can't record videos ....with the camera app ...i click on the record button but nothing happens

 

5) these are the screenshot of the video problem :

Screenshot_2014-06-03-10-49-44.pngImage EnlargerScreenshot_2014-06-03-10-49-27.pngImage Enlarger

PS===i've attached the logcat only with errors when i play a HD video ,record a video with the camera and turn on the bluetooth with the kernel "feng #28 preempt 05.09.2013" the kernel that i used for the chuwi and the odys iron kitkat rom v.1.2

PS= in the odys iron kitkat rom v1.2 everything is working fine ...i've to copy some files from that rom?

Anyway i think that are kernel related problems and it's difficult to fix it without kernel sources...

Thank you for all your work Oma !

Good news ...i think i fixed the problem of bluetooth

...now if i turn off the tablet and then turn it on ...i have to turn on wifi first (only once ) to make bluetooth work ...after that i can turn on and off  bluetooth and wifi as i want ...no problems ...

I'm using the stock mediacom kernel feng #28 preempt 05.09.2013

--->this the steps that i made :

1)extracted boot.img of Omnirom 1.1a and Odys Iron Kitkat v1.2....

2)Replaced the file "init.connectivity.rc" of boot.img of Omnirom with the one from the boot.img of Odys Iron KK v1.2

3)Added this line in "init.rk30board.rc" of boot.img of Omnirom "on post-fs" section : 

        insmod /system/lib/modules/rkwifi.ko

4)Repacked boot.img and flashed it 

 

---->Now i've still the problem of video decoding (Hd videos) and camera video recording ...there are also no battery statistics (in the odys iron v.1.2 they are working)

 

PS= the hdmi is working good but there are no settings in the menu

For a first beta build not bad. We have similar results here for different kernel.

Thank you anyway for testing.

Hi Oma there is a little update about the compatibility of chuwi kitkat rom v.2.3 and odys iron v1.2 on my mediacom tablet ...

the camera was flipped 90 degrees infact in the build.prop the line "ro.sf.hwrotation" was modified from 270 to 90 to make the camera orientation right ....after that the tablet was starting always in landscape mode (not a problem ) and the bootanimation (i changed it) was in landscape and not in portrait 

So i fixed that copying some files of the camera from the v.1.1 Kitkat build for Odys Iron where the camera was showing right with my tablet with no mods of build.prop.... .....in particular : 

 1)camera.rk30board.so from system/lib/hw

 2)libcamera_client.so ---- libcamera_metadata.so --- libcameraservice.so from system/lib

 3)than i gave the right permissions to the files and changed "ro.sf.hwrotation" in build.prop from 90 to 0

After that the tab started in portrait mode , the bootanimation that i used was showing right and not in landscape .... and the camera was perfect :)
