I have found out more about this variant! Hopefully this helps people in my situation.
This device is on a Canadian network called Wind Mobile. The model M919V can use the same roms as the T-Mobile variant, which is M919.
I have flashed CyanogenMod nightlies on it, it runs awesome, and even for a nightly it is very battery efficient and stable.
Strongly recommend it to anyone.
I had to use ouhds instead of ClockWorkRecovery (they re the same things though). It still goes through Odin, but you will have to follow the instruction online. There are a few sets of instructions that can be found through Google.
These are the instructions I followed:
