Tutorial [Q] Building the cleanest AOSP rom for LG G2 D802

Hello! I've tried to build android from sources for my LG G2 D802, but nothing works. I've used binaries, commons, and kernel from CM github. Nothing works. Can someone teach me to building aosp for D802? No, i don't want to use CM, Omni, PA because i want cleanest rom: AOSP with superuser. Thanks and sorry for my english.
