Samsung Galaxy Note 3

Use this tutorial if you want to update your Galaxy Note 3 N9000 with N900UBUDNB2 Android 4.4.2 KitKat firmware.

The Android 4.4.2 KitKat brings tons of new features and updates that should improve your smartphone’s performance. Also, you will get better battery life and tweaks.

This guide contains all the info you need to in order to successfully complete the updating process manually without waiting for the official Android 4.4.2 Update to arrive OTA. Before starting the installation you need to take a look at the preparation info below:

  • use this post only with the Samsung Galaxy Note 3 model number SM – N9000 / N900.
    - do not attempt to update any other devices using the files that I’ve listed in this article as you will end up bricking their firmware.
  • install the Samsung USB Drivers for your computer.
    - without these USB drivers installed your PC cannot detect the phone and ODIN will not push the firmware update files.
    - the ODIN app is the tool we will use in order to send the updating files to your smartphone.
  • disable Samsung KIES and any antivirus app from running on your PC.
  • enable USB Debugging from Developer Options menu.
    - in case Developer Options is not listed under Settings, then you will be forced to enable it — a guide can be found here, that’s a guide for Galaxy S5, but it works with all Samsung devices.
  • if your device is rooted, then the installation of a KitKat 4.4.2 official stock update will revoke root access.
  • if your phone runs on a custom ROM and it has a custom Recovery installed then these will be replaced with Stock ROM and Stock Recovery obviously.
  • Note 3 device with custom ROMs installed on them will see the system partition wiped in the process.
    - if you want to backup data from installed apps then you can use the Helium tool for Android.
    - if you want to sync Contacts data with your Gmail account, then read here.
  • check your device’s battery charge level and make sure that it is over 50%, this will prevent the phone from switching off in the middle of the updating process.
  • do not blame us in case you brick the phone nor in case you lose any data in the process.
  • this is a guide for advanced users, do not try to update your device in case you don’t know what ODIN or a firmware file is.
  • read the entire post, don’t skip any steps and if you have any extra questions, then you should use the comments field.

Now that you know all of the above you can continue to the next step and learn how to update your device with a brand new Android OS.

If you cannot complete the guide, then you might want to take a look at the ‘notes’ below. If the update completed without problems, then you can close this post and start to customize your Note 3′s new Android 4.4.2 KitKat OS.

NOTE 1: if ODIN freezes, it displays the ‘FAIL’ alert or some other thing block the updating process, then you will be forced to try and repeat the tutorial. Make sure that in case you repeat the guide you will not skip any steps. Also, the comments field can be used to ask for extra help, don’t be afraid to use it.

NOTE 2: if the phone doesn’t boot in normal mode and ODIN says that the updating process was successful, then you will be forced to apply a Factory Reset for your smartphone. This will help the Galaxy Note 3 boot the new ROM, but you will lose data from system partition.

Here’s how to apply factory reset for your phone from Recovery Mode: power off the phone complete, then boot into Recovery Mode. Select ‘wipe data/ factory reset’ from the recovery options, confirm the process. Wait for the Factory Reset to complete and after that you simply reboot in normal mode. Use you login details in order to take control over your phone’s new KitKat OS.
