Sometimes when your tired enough into rooting and modifying your Galaxy Note 2, there are circumstances that you need to unroot it or restore to its original factory default settings. There are some important factor why you root your Galaxy Note, this is because you need to install an Apps from Play Store that requires root before you can actually put it unto your device. But there are downside into rooting such as voiding the device warranty, sometimes it will not accept any software update. So, the only solution for this is to restore back your Galaxy Note 2 to its original firmware as it does automatically removes root also.

Installing official or original firmware will automatically remove root to your Galaxy note 2 once after flashing. Since rooting and installing unofficial firmware already voids your device warranty, that’s because the binary flash counter was triggered when you root or flash any unofficial ROM.

Do I need to reset the Binary 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” buttonto continue. Look for the Custom Binary Download, it shows a count of  how many flashing has made.  If it’s not tripped then you may not need to reset it, but if  it showed like 0/1 and modified, then you should reset it to 0 count.  You can simply alter it using Chainfire’s Triangle Away apps, 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. You can also use this method if you can’t update your device from OTA update and its show software update failure or install interrupted.  Using the stock ROM, it’s actually the same process like updating from OTA or Kies. The only differences that this is developers method, updating on OTA and Kies is end-users method.

Important Reminders before Restoring or Flashing a Stock ROM on Samsung Galaxy Note 2 T-Mobile SGH-T889

  • Make sure that your Galaxy Note 2 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 of all important files stored from your phone’s internal memory – contacts, SMS, emails, apps, photos, videos etc.  before flashing, no-matter if it is Full-Wipe or Non-Wipe stock ROM version,  just to be safe and ensure that your stored data are in  safe place  if something went wrong during the flashing process. Use any data back-up apps to easily do this task.
  • 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.

The 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.

This indicates that the flashing was already finish, and on the log box it says “All threads completed. (succeed 1 / failed 0)”.
