How to root Samsung SM-T310 v4.4.2

Hello
Because english isn't my mother tongue, i hope i can make me enough understandable.
I want to root my Samsung-TAB3 to get acces to the external SD card and be able to make a complete backup with Nandroid.
Because i am a beginner, until now i haven't changed anything on my TAB3.

The data of the tablet are:
Samsung, SM-T310, V4.4.2, Build ID: KOT49H.T310XXUBNH1,
Kernel-Version 3.0.31-2387075

I found a tutorial describing how to root
https://nasirtech.blogspot.co.at/2014/08/root-t310xxubnh1-android-442-stock.html

The CF-Auto-Root file linked in this tutorial seems to be the same as in https://autoroot.chainfire.eu

But the build-ID for SM-T310 specified in https://autoroot.chainfire.eu
is KOT49H.T310XXUBNH3 and my tab has KOT49H.T310XXUBNH1.

Will there be problemes if i use the download-link in the tutorial?

Thanks for help.
