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.

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.
