imm pretty sure i can use patchrom to try and build from our stock rom and miui7 source. dev rom would be prefered. make sure you have a debrick method before doing this! i am not responsible if your phone "eats your cat" in the words of Cyanogen team.
unless you know what you're doing, i recommend holding off for now on flashing anything not made for your device. im starting a stylo telegram chat for stylo users to communicate in real time if anyone is interested and would like to track or aid my build efforts.

edit: first patch failed
looks like we need to find framework2.jar
edit 2: seems that i may have more help than i realized from being on a stock rom and having twrp for this device.. i'm doing everything on the ms631, but it should work on tmob. currently pulling all the files. and i guess we'll see where it puts us. hopefully there wont be too much missing from the extracted files to be able to build and boot. I was running into those problems when trying to bringup cm12.1 to cm13, wcnss_lge_client isnt very friendly with MM
