While the Samsung Galaxy Note 3 at AT&T comes with a locked bootloader, you can still root the device using the "Root de la Vega" method. Below you will find a detailed guide on how to root your Note 3 from AT&T.


Before proceeding, you need to understand what this method implies.

To begin with, using this method will not trip the KNOX Flags, meaning that you shouldn't void the warranty by rooting using this method. However, since the bootloader is locked, you will not be able to flash any new custom ROMs, Kernels or any other types of custom files.

Keep in mind that after using the "Root de la Vega" method, you will need to remain on the same firmware. WARNING! Any stock OTA updates applied in the future will remove root and you may be blocked from rooting the device ever again!

Important Things You Need To Know:

  • Make sure that your Note 3 is AT&T's variant bearing the number "SM-N900A". DO NOT attempt to root any other variants or devices using this method. To make sure that your phone bears the model number SM-N900A, access the "Settings" menu and go to "About Phone"
  • This rooting tool flashes a custom pre-rooted stock Galaxy Note 3 firmware based on Android 4.3
  • While root will be achieved, the Bootloader will remain locked
  • You can use the "Helium" application from the Google Play Store in order to backup data from applications
  • Once again: no custom ROMs, kernels or custom recoveries can be installed after applying this root
  • KNOX Flags remain unmodified (0x0). This should not void your device's warranty
  • WARNING! This method will wipe all the data on your smartphone. If you use an SD card, remove it so that you won't lose any data on it. If you leave the SD card inside, all the data stored on it will be lost
  • You need to download and install the Samsung USB Drivers for PC by visiting this link. Without the drivers your handset will not be recognized by your computer or the Odin tool.
  • Before proceeding, disable or uninstall Samsung KIES from your computer
  • Disable any antivirus or security software on your PC. These programs can interfere with the rooting process
  • On your Galaxy Note 3, you need to enable "USB Debugging" from the "Developer Options" menu. To access the Developer Options menu, go to "Settings" > "About Device" and tap "Build Number" until you see the "Developer mode has been enabled" message. Now go back to "About Device", tap "Developer options" > "USB debugging"
  • Backup all the important data before rooting your smartphone
  • You will need at least 50% of battery life before proceeding
  • Before proceeding, you need to understand that rooting is something that should be done by advanced users. Things can go wrong in the process, and if you brick or damage your phone, you can't hold anyone responsible.
