LG Volt 2

I just bought my LG Volt 2 a month ago, and I'm ready to make it MINE! Unfortunately, I think this phone is too new, because I can't find anything helpful on how to root it. I tried "kingroot" and after it did a few things, it said I was successfully rooted. BUT, when I started up "SuperSU" it says it has to download some things, and its never successful and informs me to restart my phone and to press the restart tab. When I press the restart tab, it says "attempting to restart phone" but it can't. I'm on the 5.1.1 operating system, and using an LG Volt 2 (LGLS751). Is there any advise out there that someone can offer me? Am I REALLY rooted? Has anyone successfully rooted this phone yet? If so please tell me where I can find the steps. I have faith that my XDA community will pull through. Thanks everyone!
