Before you proceed, backup all your data and charge your device to atleast 50%. Though I have tested this method on my own phone and it works 100%, still I won’t be held responsible if the method below does any damage to your device. Proceed at your own risk.

Step 5: Run Odin and plug your phone into your computer.
Step 6: Click PDA button and select the root kernel file you downloaded in Step 4.
Step 7. Hit Start button to begin the rooting process.
After a minute or two, Odin will say ‘PASS’ and your note 2 will reboot. After that it will automatically go into recovery mode and perform some operation. Finally, your phone will reboot again and you will have rooted Galaxy Note 2 running Android version 4.1.2
