Root [Verizon] LG G2 Un Rooting Problem, ER:0x1117008

I rooted my Verizon LG G2, model number VS980 4G. This was a couple months ago before Kit Kat was out and before I knew anything about rooting. I tried uninstalling the root by simply uninstalling SU and all my rooted apps. When I tried to update it gave me ER: 0x1117008 and wouldn't let me update. The thing is that all root checkers and anytime I will try to use a rooted app it says I'm not rooted but in settings - about phone it states that my phone status is rooted.

Thanks in advanced,
