EDIT: I'm just going to accept that CDMA is literally the devil when it comes to Android Development, and move on.

So a few months back I installed LineageOS to my family's old Samsung Galaxy S4, to kinda get my feet wet in the "alternatives to stock Android" and "resurrecting outdated hardware" scenes. Everything went relatively well. This gave me the confidence I needed to pursue installing LineageOS to my previous daily driver, an LG G5. However, I have yet to do so because I'm not sure which ROM I am to use. There are 3 available, and I cannot tell which is the applicable one for me. They are: -h830(T-Mobile) -h850(International) and -rs988(US Unlocked). My device was covered under Sprint, but I have seen that contract through to it's end. Additionally I was under the CDMA SIM type for the United States. I have no idea which of those ROMs I am supposed to use. Thanks in advance!
