Hello owners of the JXD S7800B with 8GB, hello Oma and hello to the Crew,

first I want to thank Oma and the Crew for their genial work on porting high performanced roms to cheap devices, mostly imported from China.

I puzzled up your great efforts to a working single firmware.img of "CrewRKTablets_Odys_Iron_CM11_4.4.4_v1.2" for the gametablet JXD S7800B with 8GB nand which can be flashed through RKbatchTool easily. Oma agreed to share the files with you:

 

Rom 1 for 2013-models:

- Old kernel 1.0.9 (vsync 60 Hz)

- 1.6GHz CPU

- Working Headphones

- Tincore Keymapper is mandatory for proper working joysticks

- PC-USB-connection is working with USB-Debugging turned off

- Movie files have to be played with Bubble UPNP app from your device library

CrewRKTablets_Odys_Iron_CM11_4.4.4_v1.2_for_S7800B_Kernel-1.0.9

 

Rom 2 for 2013/2014 models:

- New compiled kernel 1.5 (vsync 60 Hz, audio denoise, power-button-debug).

  Big thanks to lujji for compiling this amazing kernel and for allowing to use it in my firmware images.

- 1.6GHz CPU

Headphones have to be turned on/off manually through widgets from apps like “SoundAbout” from Playstore

- Tincore Keymapper is optional for proper working joysticks

- PC-USB-connection is working with USB-Debugging turned off

- Movie files have to be played with Bubble UPNP app from your device library

CrewRKTablets_Odys_Iron_CM11_4.4.4_v1.2_for_S7800B_lujji-Kernel

Please read the information.txt on how to install. The general functions of Android work great an on a very high performance with this rom on my device. See the known bugs in the changelog no. 7 above. An additional benefit in Rom 2 is lujji's kernel which gives you a correct vsync and 1.6GHz clockspeed and audio denoise with the latest stockrom for 2013/2014 models (Also the so called T-models).

Last but not least: This rom works with the old loader.bin version 1.24. So there is no problem if you come from JellyBean and if you want to go back to JellyBean later.

ALL THANKS GO TO OMA AND CREW RKTABLETS FOR PORTING THIS NICE ROM ! GREAT JOB ! Enjoy the roms and make donations to Oma on Crew RKTablets if you like. I ALSO THANK LUJJI FOR HIS AMAZING JOB ON THE KERNEL.

 

If you need TincoreKeymapper for your special purposes look how to set it up successfully:

JXD S7800B Gamepad 8GB - JellyBean CM10.1 Cyanogen Mod

Hi,

 

This rom seems to have the kernel with the power bug.  If you press ppower button or it goes to sleepthe device crashed.

 

Can anybody advise on how to flash kernel from another rom over cm11?

 

thanks

Already done it, thanks  :)

 

I extracted the kernel.img using dump tool from Rileys rom, flashed and it fixed the problem.  Initially touch seemed quite unstable but after a couple of reboots it seems fine.  Rom also seems really good and stable  :)

Thanks also go to pogodancer/devs for bringing CM11 to our device   :)

Is there any updates planned?

Nice to hear that you are satisfied. About rom updates I cannot say anything. But the rom is really new compared to the stockroms. And I am sure that Oma and the Crew will continue releasing updates when there are some. After a new update will be released I try to copy the parts together for flashing it to the S7800B. Stay tuned.

@ ADz83

Because of the unified storage you cannot use mass storage. When you connect your device via USB you can access it as MTP from your computer.
