(Also you might want to setup your 64 bit Ubuntu enviroment based on Google/Cyanogenmod requirements)

Steps

Step 1.
Download Android kernel source code and cross compilation tool chains, and run these commands to under kernel source code folder compile Linux zImage

export CROSS_COMPILE=~/android/toolchains/arm-linux-androideabi-4.7/bin/arm-linux-androideabi-
export ARCH=arm
make clean && make mrproper
make mt2l03_defconfig
make menuconfig
make CONFIG_NO_ERROR_ON_MISMATCH=y -j4

Step 2:
Use mkbootimg_tools to unpack original BOOT IMG
This step will extract device trees and ram disk from your BOOT IMG (Damn you Qualcomm and your device trees)

Step 3:
Place your zImage into the folder you just extracted in Step 2

Step 4:
Use mkbootimg_tools to pack new BOOT IMG

and flash onto your phone using ADB :victory::victory:
