2. Kernel Build

 - Uncompress using following command at the android directory
       tar xvzf LGF240_Gpro_Kikat_V20e_Kernel.tar.gz        
 - When you compile the kernel source code, you have to add google original prebuilt source(toolchain) into the android directory.
 - Run following scripts to build kernel
   a) cd kernel
   b) lunch
   c) make PATH=$PATH:tools/lz4demo ARCH=arm CROSS_COMPILE=../prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi- gku_bcm-perf_defconfig zImage

* U+ : gku, SKT : gksk, KT : gkkt

        * lz4demo : More information can be found at "https://code.google.com/p/lz4/"
 - After build, you can find the build image(zImage) at arch/arm/boot
