In order to make sure that you will successfully flash the new update at your first attempt, read the guidelines below:

  • Make sure that your PC has all the Samsung USB Drivers installed. Download link here.
  • Stop any antivirus application and the Samsung KIES from running on your computer.
    – such PC apps will interfere with ODIN and it might not allow the installation of new firmware files on your Note 3.
  • Note that in case your Note 3 Exynos runs on a custom ROM, then you will lose all data after using ODIN to update it to Android 4.4.2 official firmware.
    – backup all your important data before starting the installation.
    – Note 3 Exynos with custom ROMs will have all files deleted from system partition, while the internal and external storage will be left unaffected.
  • Note 3 Exynos running stock Android OS will not be affected by the KitKat update process.
  • Go to Developer Options and enable the USB Debugging option.
  • Use the Helium app in order to backup data from installed apps.

Since you’ve read all of the above, now you can finally start the installation process of a brand new firmware update for your device.

How to flash Android 4.4.2 N900XXUDNA6 for Galaxy Note 3 N900:

  1. Download the N900XXUDNA6 firmware zip from here or here.
  2. After the download is complete you need to unzip the archived contents.
    – you will get the N900XXUDNA6_N900SERDNA6_N900XXUDNA1_HOME.tar.md5 file.
    – do not extract any further than that.
  3. Download Odin3 v3.09 from here.

  4. Power off your Note 3 now.
  5. Boot the phone in Android Download Mode.
    – if you don’t know how to boot Download Mode, then you can find help here.
  6. Launch Odin 3.09 exe on your computer.
  7. Now use the USB cable and connect the Note 3 with your PC.
    – wait for Odin to detect the phone, then you can continue to the next step.
    > if the phone is not detected by Odin, then it would be best for you to re-install the Samsung USB Drivers.
    > when everything is set and the phone was recognized you can get to the next step.
  8. Go to Odin, click the AP button and then load the N900XXUDNA6_N900SERDNA6_N900XXUDNA1_HOME.tar.md5
    > make sure that the Re-Partition option is not enabled.

    > don’t press any buttons until the process is complete.
  10. When the installation is finished you will see that ODIN displays the ‘PASS’ alert, while the phone reboots in normal mode.
    – disconnect the phone from PC when the Note 3 boot animation screen appears.
  11. Wait for the Note 3 to load the new home screen and after that you can begin testing all the new features.

These were all the steps that you had to follow in order to successfully update your smartphone. If the installation was successful, then you can close this guide and start testing / customizing the Android 4.4.2 KitKat OS. If you’ve encountered problems during installation, read the ‘notes’ below.

NOTE 1: If Odin freezes, closes unexpectedly or the phone gets blocked, then you will be forced to repeat the entire tutorial once again. Make sure that you won’t skip any steps that I’ve listed above and ask for help in comments.

NOTE 2: If Odin completes installation, but the phone doesn’t go past the Samsung Galaxy Note 3 animation, then you will have to apply a ‘factory reset’. This process will remove all data from system partition, but it will force the Note 3 to boot in normal mode. Here’s how to do that:

  • power off the phone completely.
  • boot it in Stock Recovery Mode.
    – it can be done by pressing and holding Volume Up, Home and Power at the same time.
    – release the buttons when the Recovery Mode menu appears.
  • select ‘wipe data/ factory reset’, confirm.
  • when the process is complete you need to select ‘reboot system now’ and wait for the boot to complete.
