SM-G930T Root Doesn't Void Warranty

The latest root method for the Samsung Galaxy S7/S7E (AT&T/T-Mobile/Verizon/Sprint)
Does not void warranty and also does not trip the KNOX counter.
In order to remove root (un-root) you can flash the original firmware in Odin.
Also to answer any further questions the root does work on the latest T-Mobile update for the S7
(G930TUVU3APG1).
