If you have modded your Galaxy Note 2, like rooting and installing stock rooted ROMs you may need to install the unmodified, unrooted and original firmware. It can't just simply revert back to it's original default settings without flashing required like performing a factory reset. This restoring process works on all Samsung Galaxy Note 2 variants - International, United States and Canada.
Do I need to unroot my Galaxy Note 2 first?
No need to unroot, installing official or original firmware will automatically remove root to your device once after flashing. Since rooting and installing unofficial firmware already voids your device warranty, that's because the binary flash counter is has triggered when you flash any modified or rooted ROM.
Do I need to reset the flash counter when already tripped?
Yes! If you need to completely restore back without a trace of any modification, you should reset the flash counter. You may check it via download mode - pressing and holding (volume down + home + power buttons) then press "volume up" button to continue. Look for the Custom Binary Download, it shows a count of how many flashing have made. If its not tripped then you may not need to reset it, but if it showed like 0/1 then you should reset it to 0 count. You can simply alter it using Chainfire's TriangleAway app, it's free to download it here.
Is this method useful in any other way?
Aside from bringing back your device from using unofficial firmware, this is also useful for fixing soft-bricks. If you messed-up from rooting or installing modified ROM then you need to fix it by restoring back the original firmware and bring back your device to be useful again.

1. Important Reminders before Restoring or Flashing a Stock ROM on Samsung Galaxy Note 2
- Make sure that your Galaxy Note2 battery is fully charge.
- Stock ROM packages comes in two formats the ‘Full-Wipe’ (delete your stored data after flashing) and the ‘Non-Wipe’ (it doesn’t delete your phone’s stored data) but it is highly recommended to make a back up all important files stored from your phone’s internal memory – contacts, messages, etc. before flashing no-matter if it is Full-Wipe or Non-Wipe, just to be safe and ensure that your stored data are in safe if something went wrong during the flashing process.
- Use a PC or laptop that runs in Windows OS, with a good and perfectly working USB serial port. Odin will not work on MAC OS.
- Use the supplied USB cable for your Galaxy Note 2.
- Enable USB debugging from your phone’s settings. Go to Settings > Applications > Development, and tick the box that says ‘Enable USB Debugging’.
- Ensure that KIES is closed and not running in the system tray! Kies will interrupt and doesn’t like Odin, it will block you from flashing.

4. Run and Configure Odin
Run Odin downloader Odin3_v3.07 on your PC desktop. Watch out the check-boxes options on the right top of Odin, ensure that the ‘RE-PARTITION’ is unchecked, only the ‘AUTO-REBOOT and ‘F.RESET TIME’ checkboxes are both remained checked.

In Odin window – the ID:COM box will turn to blue color and indicates the COM port number and a word “Added” on a log box will prompt you that the device is already detected or recognized by Odin. Your COM port number might be different from mine. If you do not see a COM port number then there’s something missing or wrong. You may read again from the top of this post.
7. Set and load and the binary .tar.md5 fileT he stock ROM is pack in One .tar.md5 file only. Now, you need to just simply click on the PDA button, then browse to the folder where the .tar or .tar.md5 you have previously extracted and then select and load it.
8. Begin Flashing the stock ROM
Once if all set and ready to fire-up, hit the “START” button in Odin to begin flashing the stock ROM.
Do not ever interrupt the phone while already in flashing progress, like disconnecting the cable or turning off the device. Just wait until it completely finish.
9. Wait for the word PASS!!
When the Stock ROM installation successfully completes, you will then see a word “PASS” in Odin. This indicates that the flashing was already finish, and on the log box it says “All threads completed. (succeed 1 / failed 0)”. The phone will just then automatically reboot, then it’s time to remove it from PC or laptop USB connection.
