Default [Q] How do I build a ROM for D2LTE? (D2att)

I was asking because I have tried CM's guide, multiple guides on here... Nothing seems to work. I'd like a step by step guide on how to
1: Add / sync repo for latest CM11
2: Get ALL device repositories for d2
3: Download kernel and device source
4: Download Linaro toolchain for 4.4
5: Build rom and kernel with Linaro
6: Cherry pick / add features
All help will be appreciated extremely! I'm young and know almost nothing about coding but I know my way around a terminal. All the times I've tried building I've gotten either a failed build or a successful build that doesn't boot...
