Yes! If you need to completely restore back without a trace of any modification, you should reset the flash counter.

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.

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.
