Galaxy Note 10.1 N8020 users recently received the latest Official Jelly Bean Firmware Android 4.1.2 XXBMA7 with minor bug-fix updates, as part of regular maintenance update. As the firmware is an official release, it removes root access to the device soon after installation. Hence, it is imperative to root the device again to regain full system access (Super-User access) and be able to install third-party root-based apps, custom ROMs and latest system tweaks.

NOTE: The root method used in this guide makes use of ODIN flash tool instead of the traditional ClockworkMod (CWM) recovery. The device's hardware warranty will be void once it is rooted. However, its warranty can be restored by just reinstalling the official firmware update. You must download and install the Root Checker app to verify if your device is actually rooted or not.

How to Root Galaxy Note 10.1 N8020 on Android 4.1.2 XXBMA7 Official Jelly Bean Firmware

1. Extract the downloaded CF-Auto-Root zip file to get a .tar.md5 file within it.

3. Switch off your tablet and wait for vibration (about 5 to 6 seconds) to confirm complete device shutdown.

If the message fails to appear, then just try another USB port (preferably the one at the back of your computer). If all else fails, then just reinstall the USB drivers for your phone on computer. When the successful "Added!!" message appears in Odin, proceed to the next step. Now, the ID: COM port with a number turns Yellow if you successfully added your device.

7. Choose the following files in Odin using respective buttons:

  • Click the PDA Button, and choose CF-Auto-Root-p4notelte-p4noteltexx-gtn8020.tar.md5.

8. In Odin, enable Auto Reboot and F. Reset Time options by selecting their checkboxes.

9. Verify that everything in step 7 and step 8 are done correctly before proceeding. Then hit the START button to begin the root flashing process.

10. After the root is installed, the tablet will reboot and a PASS message with green background appears in the left-most box at the very top of Odin. Now, unplug the USB cable to disconnect your device from computer.

Your Galaxy Note 10.1 N8020 is now rooted on Android 4.1.2 XXBMA7 official Jelly Bean firmware. You can now install third-party apps that require root access.
