How to root AT&T Galaxy Note 3 running N900AUCUBNB4 software version from OTA

AT&T finally released a new software update for its new Note 3 (SM-N900A) via OTA, sadly this update is not as we expected since it only contains general enhancements rather than new OS update. As usual, when you download and install the N900AUCUBNB4 updates on the AT&T Galaxy Note 3, you will lose root access, the root exploits that exist on your device will be wiped during the upgrading process.


Although the NB4 update only a minor update and just deliver a few improvements such as the Samsung Account updates, Android patches, Google Drive app, GMS apk and library updates. Probably the most important enhancement is Firmware Over The Air (FOTA) improvements, it’s useful to prepare your device to receive the future official Android 4.4.2 KitKat update.

For those who have done the updating, it seems you don’t have to be worried, considering that we are still able to root AT&T Galaxy Note 3 running N900AUCUBNB4 software updates by using the one-click tool that is easy to use.


  • A Windows Computer (Win 8, 7 or XP) and a Samsung OEM USB cable.
  • Samsung USB driver already installed on your computer.
  • Download Kingo Android Root v.1.1.8, the latest version doesn’t work for NB4 update.
