Install XXUDNB2 Android 4.4.2 KitKat Official Update on Galaxy Note 3

Samsung just rolled out the official OTA Android 4.4.2 KitKat update for the Galaxy Note 3 N9000 handsets. The firmware is as usual gradually released and currently it is available in limited markets only. The update is dubbed as XXUDNB2 and represents a major OS improvement that can be anytime flashed on the Samsung Galaxy Note 3. Since XXUDNB2 is OTA available and since you might have problems in receiving the same, during the following lines I will show you how to manually install the official Android 4.4.2 KitKat software on your Galaxy Note 3, so don’t hesitate and check the guidelines from below.

First of all, it should be clear for you that this is a manual update operation. Even though you will manually install the firmware, you will still apply the official XXUDNB2 Android 4.4.2 OS – the same update as the OTA release. Therefore your Galaxy Note 3 will be manually updated to official Android system. Thus, this operation is official and can be safely completed even by a newbie – you don’t have to use complex or custom tools and everything will be working just fine, especially if you follow the steps from below.

XXUDNB2 brings the latest Android 4.4.2 KitKat features, apps and capabilities to your Samsung Galaxy Note 3, this update being also stable, fast and cool in term of themes, wallpapers and so on. Since we are dealing with an official roll out, the XXUDNB2 works without lags or issues and according to those who have already installed the Android KitKat firmware, the same is smoothly running on the Galaxy Note 3. The update also comes installed with some stability improvements and with other features that can be used for optimizing the performances, customizing the looks and upgrading the battery life of your phablet.

As you will see, for being able to manually update your Note 3 to official Android 4.4.2 OS, Odin will be used. As you might know, Odin is an official tool which is designed and also offered by Samsung. Odin is usually used especially on update operations, though it will work only for Samsung branded devices. Therefore, you have nothing to worry about; XXUDNB2 is not a custom ROM so root access won’t be revoked. Furthermore you don’t have to flash the update file by using a custom recovery as Odin will take care of that.

Of course, this step by step guide can be safely applied for both rooted and un-rooted / locked Android smartphones. If your Note 3 is currently rooted or flashed with a custom ROM, now root access will be revoked and stock Android OS re-installed. Because of that this guide should be bookmarked – you can anytime use it for restoring the warranty on your phablet (the warranty usually gets void when performing unofficial procedures like gaining root access, unlocking the bootloader and so on) or for unbricking your Samsung Galaxy Note 3 N9000 by downgrading to stock Android XXUDNB2 KitKat firmware.

When using Odin, everything should work without any kinds of issues. But, in rare cases bad things might happen. Because of that the best will be to backup your data before going any further – save the data which is there on the internal storage memory of your Android smartphone. In order to make a proper backup I recommend you to access Google Play and download free and dedicated backup and restore apps; in this way you can save your contacts list, text messages, EFS folder, market apps, personal accounts and info and everything else that you might need afterwards.

In other point of ideas, for safely completing this tutorial you will have to use a computer, your Android device and its USB cable. Since a connection between these devices must be established, on your phablet you should enable USB debugging option – just go to “menu – settings – developer options”. Also, the best will be to deactivate the security protection that is featured on your PC – in some cases the antivirus programs for example are interfering with the update process. Furthermore, you should charge your Note 3 before going any further – if your smartphone gets turned off in the middle of the installation procedure it might also get bricked. Finally, do note that Samsung released XXUDNB2 Android 4.4.2 KitKat OS only for the Galaxy Note model number N9000. Because of that this tutorial is compatible only with the mentioned Android smartphone – don’t use the steps from below for a different or similar device as you can damage its system.

How to Install XXUDNB2 Android 4.4.2 KitKat Official Update on Galaxy Note 3

  1. Go here and download the update file on your computer.
  2. Then, download Odin.
  3. Unzip Odin on desktop and then install the program by following the on-screen prompts.
  4. Unzip the firmware file on the same folder as Odin.
  5. Install the Galaxy Note 3 drivers on your computer – you can use Samsung KIES for completing this task.
  6. Now, run Odin on your PC and turn off your phablet.
  7. Enter your Android device in download mode.
  8. For reaching download mode press power, volume down and home buttons at the same time.
  9. Use the USB cable and connect your smartphone with your computer.
  10. Then take a look on Odin; on the program the “added” message should be displayed while the ID:COM section should be yellow or blue.
  11. If that’s not happening, try to close Odin. Also unplug the USB cord and reinstall the drivers on your computer. Then repeat the steps from above.
  12. From Odin pick the update file. In order to do so, just click on “PA”.
  13. Don’t change anything else in Odin and click on “start”.
  14. The Android 4.4.2 KitKat OS will now be installed on your Note 3.
  15. In the end, on the program the “pass” message will be displayed. Also the ID:COM section will be now green.
  16. You can safely remove the USB cable; reboot your phone because you are done.

Some users reported that during the update process Odin was stuck; if that happens, close the program and unplug the USB cord. Force restart your device, reflash the drivers on your computer and reapply the steps from above. Also, your handset might get stuck in a boot loop after applying the firmware; in that case reboot your Android device in recovery mode. From there select “wipe data factory reset” and “wipe cache partition”. Return, select “reboot system now” and you have solved your problem. For a dedicated troubleshooting guide, don’t hesitate and use the tutorial from here.

  • Scott Alan Bacon

    I can’t get the Odin program. The link takes me to a download page that keeps downloading some junk ware programs. Nothing that says Odin. On a side note, when reading this I decided to check my phone (N900A) for an OTA update…it updated but it isn’t 4.4.2, it is 4.3 and a different build. Weird. I’m on AT&T in Kentucky stock OS no rooting.

    It only works on N9000. The 3G only model of Note3. The rom itself doesn’t have LTE support. So no, not good for 900, 9005 or any other models.
