Why am I getting error messages when I try to root my Galaxy S5?

[AC Question]

Rooting my galaxy s5 fails.

I decided to root my samsung galaxy s5, model SM-G900h. I do everything as the tutorials, but when I press start the box shows fail in red.

The message box show:

Re: Rooting my galaxy s5 fails.

Welcome to the forums. The last I knew, the newest update to the S5 broke root; using any root method prior to the new release will result in a failed attempt.
