Root rooting my sprint lg g2 after update

[charleyb79]

My g2 updated last week and now I keep getting a message that it needs rooted. I don't know where to start and the phone is running terribly! HELP PLEASE! I am illiterate when it comes to all this so as simple and yet specific as possible. Thanks!

Hi. Did you root your phone before the update?

Sprint tech did the last time I had gone in for problems. I had no idea what it even meant and still don't really.
