Root AT&T Samsung Galaxy Note 3 SM-N900A with Root De La Vega (KNOX Flags Not Tripped)

AT&T Samsung Galaxy Note 3 has received its first root from DesignGears and Chainfire, but it will come with a cost as you will be forced to wipe all data in the process. Also, after applying the ‘Root de la Vega’ method you will also need to stay on the same firmware, any stock OTA Updates applied will remove root and you might not be able to apply root ever again for your Note 3.

The best thing about this root method is that it doesn’t trip the KNOX Flags, which means that you won’t void your warranty. Note that you can’t flash any new custom ROMs, kernels nor any other type of custom files, since the bootloader of AT&T Note 3 remains locked. However, we’re hoping that soon someone will manage to release a bootloader unlocking tutorial.

For you to be able to root your AT&T Galaxy Note 3 you should read the guidelines below and learn that a Full WIPE process is recommended, as otherwise root cannot be achieved. Read the preparation guide info below and make sure that you know what you’re doing before continuing to the next part of this post. Here’s what you need to know before starting the root process of your Galaxy Note 3 with Root de la Vega by DesignGears and Chainfire:

  • Use this post only for the AT&T variant of the Samsung Galaxy Note 3. Check the phone’s model number in Settings, then About Phone menu and verify that the version number is set to SM-N900A.
  • Do not attempt to root any other devices using the instructions listed in this post.
    – If you own a Verizon Galaxy Note 3 device and you wish to root it, then you should visit our post here.
  • This Root de la Vega rooting tool flashes a custom but pre-rooted stock Galaxy Note 3 firmware based on Android 4.3.
  • The Bootloader of your device stays locked, but root will be achieved.
  • Use Helium app from Google Play Store in order to backup data from installed apps.
  • No custom ROMs nor kernels nor custom recoveries can be installed after applying this root. You will need to wait some time before someone manages to unlock the Note 3 bootloader in order to start installing custom things on it.
  • This guide will not trip any KNOX Flags, as the 0x0 value will stay unmodified. The Galaxy Note 3 AT&T warranty won’t be voided by this process.
  • The tutorial will wipe every single file from your smartphone. It doesn’t matter if it is system, internal or external partition.
  • IMPORTANT: make sure to remove the External microSD card from your device in case there is one installed on it. You’ll find a step in the tutorial that will tell you the same thing, so you shouldn’t forget about it.
    – if you leave the external microSD card connected with your device, then you will lose all data that’s stored on it.
  • Download then install the SAMSUNG USB Drivers for your PC from here.
    – if you don’t install the drivers, then the AT&T Galaxy Note 3 won’t be recognized by your PC nor by Odin 3.09 tool. That’s the Windows app that we’ll use in order to flash the rooting files for your device.
  • Disable / Uninstall SAMSUNG KIES software from your computer before starting the root.
  • Disable any antivirus / security applications from running on your PC. Such apps are interfering with the rooting process and you might not be able to complete the tutorial.
  • Enable the USB Debugging option from Developer Options menu.
  • This is a tutorial that should be completed by advanced Android users.
  • Don’t held us responsible nor the Root de la Vega developers in case you damage or brick the AT&T Galaxy Note 3 device.
  • Backup all important data before starting to root your smartphone. Data that is lost in the process cannot be recovered.
  • The phone’s battery power charge level has to be over 50%. This prevents it from powering off during the root.
  • If you cannot complete the guide or you don’t understand how to apply some of the steps below, then you should ask for more help in comments or visit the XDA AT&T Galaxy Note 3 Root thread- link here.

Now that you know all of the above, continue to the next part of this post.
