Why am I getting this error message, though it's presented that all Galaxy S5 can be rooted?

[AC Question]

Just installed and ran "towelroot" v3 according to videoclip "Root all Galaxy S5 variants".
All went just as was described in the clip. But after pressing the "make it ra1n" button I received the message: "This phone isn't currently supported".
I donated and hoped it was real. So please lone me some help here.

Mobile: Galaxy S5 model SM-G900F
Android ver 5.0

Welcome to Android Central!

It could be that the update that you did on your phone is not supported with TowelRoot.
