This guide will show you step-by-step how to root your SM-N900A AT&T Galaxy Note 3. This root method is going to be a little different than your usual Samsung rooting guides since Knox is included in the AT&T Galaxy Note 3.
With Samsung Knox security the Android community needed to find a work around to root the device without alerting the security software and letting Samsung know you modified your device some way.
Currently this guide will root your AT&T Galaxy Note 3, but there is still no way of installing a custom recovery (CWM/TWRP) yet. Once the Android community finds a way I will be releasing a guide on this site, so stayed tuned!
Follow the guide below to root the AT&T Galaxy Note 3!
This will delete EVERYTHING from your phone! BACK IT UP!
1. Remove external SD card from your phone if you have one.
2. Now enter into Download Mode by turning off your phone. Then press and hold the volume down, power button, and home button at the same time. You will get to a screen to ask you to press the volume up to continue, press it.
3. Now plug in your microUSB to your phone and the USB cable to your computer.
4. Download and extract N900AUCUBMI9_VEGA.7z using the link below:
5. In the extracted folder you will get "N900AUCUBMI9_OneClickBin" application. Click start and wait about 5-10 minutes until it passes and your phone reboots.
Also you should get a yellow or blue box at the top of the application, if you do not then install Samsung USB drivers and try again.
6. Enter into Download Mode again (repeat step 2) and keep your phone plugged into the computer.
7. Now open "Odin3 v3.09". Then select "AP" and locate and select "Root_de_la_Vega.tar" file. This file was in the same extracted folder as Odin.
8. Now click "Start" at the bottom of Odin. This process will take 5-10 minutes so be PATIENT! Do not touch your phone! After the process is complete your Galaxy Note 3 will automatically reboot in the normal state.
9. Now unzip Root_de_la_Vega.zip, this file is located in the extracted "N900AUCUBMI9_VEGA" folder.
10. With your phone still plugged in transfer "root_de_la_vega.sh" and "root_files" (folder) to your phone. NOTE: Do not transfer these files into a folder, just the general phone directory!
11. Now reboot your phone by holding the power button and then selecting restart.
12. With your phone plugged into your computer delete both "root_de_la_vega.sh" and "root_files" (folder) from your phone.
13. Again, fully reboot (repeat step 9).
14. Once your phone is fully booted up your done. Your Galaxy Note 3 should now have SuperSU installed and you can use rooted apps like Titanium Backup!
