Root G900TUVS1FOJ4 (5.1.1) t-mobile S5 white - Help

Hello

I cannot get a clear answer whether this model is rootable, or there is a flashable rom with stock root built into it. I have seen many dead links, removed pages, and 5.0 and 4.4.2 root methods.

is the new s5 G900TUVS1FOJ4 (5.1.1) rootable?

why is there no method described in the all things root section for the s5 (dead links)

What method is best for me to root my phone, and change the ugly white theme to dark everything and have wifi calling .

I did try to look these things up before I posted, some wisdom from the community would be appreciated.

Thank you
