I was just about to root and then call and cancel my insurance.. then I started noticing threads where people have claimed root on 4.4.2 without tripping the Knox flag.
This is a new phone, never before rooted. I do own Mobile Oden Pro and Triangle away and am willing to purchase other apps if needed.
Either way this phone will be rooted but I would like to keep my insurance warranty if possible.
Edit.. custom recovery would be an added bonus not is not needed.
