    – Odin is the app that we will use to install this new firmware for your device.
  • make sure that you have disabled the Samsung KIES and any antivirus application from running on your PC.
  • enable USB Debugging from Developer Options menu.
    – in case Developer Options isn’t shown under Settings, then you will need to enable it first.
  • if your T-Mobile Note 3 is rooted, then by installing a new stock update you will revoke its root access.
    – the process will also replace any custom Recovery that you might have installed on your device.
  • in case your device has a custom ROM installed on it, then your phone will be wiped clean in the process.
    – however, the files stored on the internal and external storage won’t be affected by this process.
    – the only part wiped will be the system partition, that’s where the custom ROM is installed and you will lose installed apps and some other similar files.
    – if you want to save data from installed apps, SMS text messages or other similar files, then you can use Helium for Android.
    Contacts and People details can be synced with your default Gmail account.
  • this is a post for advanced users, do not blame us in case you end up bricking your device.
    – make sure that the phone’s battery charge level is over 50%, this will prevent it from switching off during installation.
  • read the whole guide and do not skip any steps if you want to complete update at your first attempt.

If you’ve encountered problems or in case your device isn’t running as it should with the new firmware, then you should read the ‘notes’ below, too.
