Can't get root permission og LG G2

[AC Question]

Hi,
I'm trying to install adfree on my LG G2. I've completed all preperatory steps (LG driver, debugging permission, developer status). ran my adfree/apk file, but, alas, upon completion, got a message saying that no root permission was available.
What's wrong?

Hi,

How about the upgrade of official. Can I upgrade my g2 again if there is a new version release?
Thanks.
