mobile

Well, I tried flashing CWM on my T mobile Note 4, and it never worked. I used Odin, and while it said it worked, I still get stock recovery. HOWEVER, when I check for OTAs, my phone says it has been modified and I need to use Kies. I'm on stock firmware and haven't even rooted, so wold it be posible, much less safe, to update via Kies when lollipop rolls out? I haven't deleted any stock apps, and as previously stated am on stock firmware and recovery and am
not rooted.
