Root regarding G928T

I've gotten conflicting results when reading the forums about whether or not the G928T is rootable via Arter97's kernel. In how to guides I see evidence that it might be but on the Arter97 dev thread it says coming soon.. yet at the same time in update 3.6 it says "added support for T...".

Can anyone confirm if the Arter97 Kernel can be used to get root access on a G928T running 5.1.1?
Also, I woke up this morning to an update from T-Mobile... I'm assuming I shouldn't take the update if I plan to root? Anyone have any suggestion there?
The version #'s are as follows: G928TUVU2COI5/G928TTMB2COI5/G928TUVU2COI5 in the update details...
