In this video tutorial, I'm going to build the kernel for my Samsung S4 (I9506) codename: ks01lte
PREREQUISITE

☐ 64bit Linux system (you can also install it in vmware or virtualbox)
☐ kernel source of your phone (you can download it from the manufacturer's site)
☐ toolchain (download it from googlesource or build your own from source)
☐ android image kitchen (for repacking kernel)
☐ and some patience
