Root Samsung galaxy s5 ATT Kitkat 4.4.2 or 4.4.4 easily and safely. 

The rooting processes of some Samsung mobiles became relatively difficult especially with each new update for kernels. for example rooting the galaxy s5 at&t device with NG3 update can't performed as with previous update, such as ND3,
using  one click way with towel root  or king-root.
So here is the easiest way to root galaxy s5 AT&T mobile SM-G900A if you on android version (4.4.2 kernel NG3), or version 4.4.4 kernel with either OA1 or OA2 kernel updates.



What is the root?
Android root is similar to jailbreak in iphone devices with some differences between the results between IOS and android OS. It will allow you to install applications that require root access. Also after rooting your galaxy mobile, you will be able to unlock bootloader of your phone, install custom ROM or custom recovery into your phone, remove system and unnecessary applications,... etc.

    1. It seen that your device has newer ROM version than what we talking about
      this method is applicable only to 4.4.2 Version and kernel version (Baseband) ND3 or NG3
      if your device has newer version you need to download stock ROM that is same or newer than your existing version( ex. if your phone was on lollipop version(5.x) so you can download lollipop stock ROM or Marshmallow (6.X) stock ROM).
