Many users want to know how backport kernel to make bluetooth work , in this guide i will try to show you the steps to do it:

1- First clone linux-next (don't download zip or tar file you must clone)

git clone https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next -b v4.2-rc7 linux-kernel

2- Clone your kernel

3- Clone backport patch

https://github.com/ubuntu-phonedations/backports.git -b for-ubuntu backport-ubuntu

4- Under backport-ubuntu folder, run this command (you must put absolute path for kernel)

./gentree.py --copy-list ./copy-list --integrate --clean --git-revision v4.6 [path-to-kernel-next]/kernel-next [path-to-your-kernel]/your_kernel

If you try to compile kernel maybe you will get some error, to avoid it try first to apply this patch :

First check if patch is ok
git apply --check hid-generic.patch

Second if there is not any error apply it

git am --signoff < hid-generic.patch

Finaly replace backport folder (in your kernel )with this

backports.tar.xz

Link to download hid-generic.patch
hid-generic.patch

Also its important : remove all CONFIG_BT* in kernel config

I have ported two device Moto G 2014 and LGV20.

@jiho nice
the audio call not work, also fingerprint.
I'm working now to fix this issues

@jiho can you reboot to recovery twrp,

Then :

adb shell
ls /data

verif if android-rootfs.img & rootfs.img exists

Also can you give me the log under
/data/system-user/var/log

Also you must format data partition before install to remove any encryption

Did you installed vendor.img?
There is twrp install file which more simple and it install all needed files
