How to use LS980 with T-Mobile ?



Hi all,
I have an LS980 that I am trying to get to work for T-Mobile and have a few questions. I know the phone is capable of this feat, as I did it once, and have no recollection of what we did. It has since been flashed to stock.

I am basing a lot of what I'm trying off of this article, since it is basically what I'm trying to achieve.

I am able to flash the LS980 to stock as outlined in this article.
However, at 94% progress it says it is waiting 120 seconds for a reboot. At this point the phone reboots into the OS and seems to stop communicating with the LGFlashTool, so I never end up at 100%, though the Phone seems to be running. Not sure if this matters.

I am able to use IORoot successfully as well (verified with Root Checker

If I try using AutoRec to install TWRP, I can typically boot into recovery once, but after that one time, I enter a boot loop, and am unable to get into the system or recovery. In this situation, I have just ended up flashing to stock again.

My Questions:
I want to use the LS980 on Tmobile. It seems possible if I tweak the radio, the APN, prop builder, and a variety of other things. Alternatively, it seems like I could just flash a Tmobile ROM . If I flash a T-Mobile ROM , would I still need to go through all the system changes to make the phone work on T-Mobile's network, or is that sort of 'baked' into the ROM already?

Should I be concerned that while flashing to stock, it never hits 100%, even though it leaves me in the system? I have tried looking into it, but haven't really found any info on the matter.

Others who have used the LS980 on T-Mobile, did you opt to tweak the stock image settings, or go with a ROM? What was your reasoning? (ROM seems way easier overall, but curious none the less).

Once I have chosen Stock with settings changed, or T-Mobile ROM, what specifically needs to happen to get the phone access to the T-Mobile network? I have a SIM card from my other T-Mobile phone that fits the LS980, but I'm not certain what beyond putting the SIM into the phone needs to happen? (I don't swap phones enough to remember this). I'm sure there's a 'let me google that for you' coming my way on this one, but if there is, I just can't figure out the right way to ask the question.

I appreciate everyone's help with this.
