As you probably already know –especially if you're a Note 3 owner-, Samsung has recently started rolling out the official Android 4.4.2 update on its latest phablet. The launch currently takes place only in certain regions, and the first model to take advantage of the new OS was the LTE N9005 model.

The good news is that Samsung has now launched the update for the N900 model as well, which is the International Octa-core Exynos variant. If you happen to own this particular device and you don't want to wait for the rollout process to expand, then you should find this guide most useful, as it allows you to apply the official Android 4.4.2 update manually.


  • This guide allows you to flash the official KitKat OS on the Samsung Galaxy Note 3 model number SM-N900 (Exynos variant). Don't attempt to apply this update to any other device or Note 3 variant
  • If you want to apply the proper update for the Snapdragon 800 variant (model number SM-N9005), then follow this link instead
  • You can find out your handset's model number by going to "Settings" > "About phone"
  • In case your Note 3 runs a custom ROM, then applying this update will wipe the system partition. Create backups if needed, and sync your contacts with your Google account
  • If your Note 3 runs on stock Android OS, then you don't risk losing any data
  • You'll need to connect your Note 3 to a computer that has the proper Samsung USB drivers installed. You can download them from this link
  • Before proceeding, disable KIES as it can interfere with the flashing process
  • Disable any security software on your PC as these types of programs can also interfere with Odin and the installation process
  • You need to enable USB Debugging on your smartphone. To do so, go to "Settings" > "About device" and then tap "Build number" until the message "Developer mode has been enabled" appears on-screen. Return to "Settings", tap "Developer options" and enable "USB Debugging"
  • Make sure your smartphone's battery is at least at 70% full. It's crucial for your device not to run out of battery during the flashing process
  • This is a guide for advanced users. Proceed at your own risk. Should anything go wrong, you cannot hold anyone responsible
  • Don't skip any steps
