lujji has built an amazing kernel which is running on 1.6GHz working for all S7800B-models (built in 2013 and 2014). lujji agreed to include his kernel into a complete firmware image. So users don?t have to flash twice. Big thanks to lujji.

I also thank Oma for his Clockwork recovery and the Format-Nand-script I used in the firmware.

I just modded the firmware slightly to have more comfort. Please read the instructions and have phun.

S7800B_V1.5_1.6GHz_JB4.2.2_2014-03-27_lujji-kernel

Kernel-Mods by lujji:

Thanks,,, been using similar but without the mods so this is welcomed

Can future releases be CMW roms, that way we can do everything from tablet and not have to use desktop/lappy and also update without doing clean installs

does the stock keymapper still work with this ?

Sorry but this step is still far away. First will be to eliminate existing bugs in the other firmwares and to have a fully working KitKat rom. Maybe we will see Lollipop on this device in the future but this depends on Oma's amazing work.

But if someone has the knowledge and the time to build the roms as an update.zip I appreciate it.

I don't think so but you can try it. I heard that you should delete and clean the JXD stock keymapper and its settings before using Tincore keymapper. What about the built-in Tincore app ? Have a try and give us your feedback. Thanks.

Hello to all, this is my first post. Long time reading first time writting...

Well is there any way to change the wallpaper forever? I have the default one and everytime I change it became the default one later.

Thanks a lot

pogodancer · « **Reply #8 on:** November 08, 2014, 10:21:07 am »

@ jako

You can try a wallpaper app.
You can try to change the wallpaper in system/media/rkfactory.
You can try to set the lcd-density in system/build.prop to 160.

Everything without any guarantee.

Try to change dns to 8.8.8.8 and 8.8.4.4

This should help bypass ISP dns and then you should be able to download from mega.

Added alternative download hoster Zippyshare in post #1.

Thanks. Changing the DNS worked.

Thanks for the alt links as well.

@ deysmacro

Thanks. I didn't know.

I have a huge battery drain with this rom. Any idea of how to fix it? My last rom (Supercharged) had twice duration more or less

Thanks a lot

pogodancer · « **Reply #15 on:** November 09, 2014, 05:08:18 pm »

@ jako

to improve battery drain try setting keep wi-fi on during sleep to never. Good luck.

Lowering the brightness and setting CPU governor to 'ondemand' or 'interactive' also helps.

GRiM · « **Reply #17 on:** November 09, 2014, 10:13:56 pm »

Just wondering if you would happen to have a 6GB nand zip?
