LG G3 US Cellular (US990)

[Mister_Cliche]

Hello! 

I've posted several posts on XDA forums with absolutely no response. Maybe my wording is complicated so please bear with me.

I currently have an LG G3 from carrier US Cellular. Running it's stock ROM, Android 4.4, basically brand new. 

I want to install CM12 and would like to know if I even can. I understand the model number is different and I have absolutely no idea what that means to tell you the truth. I'm not a phone expert, somewhat new to Android, and definitely new to rooting and installing ROMs.

I absolutely hate LG's skin and it's ruining the experience of having this beautiful phone. 

A TL;DR if needed
Phone: LG G3
Carrier: US Cellular (US990)
Can I install CM12?

I appreciate ANY feedback/help.
