The Galaxy S4 Zoom device has received its own Android 4.4.2 KitKat update and you can use this tutorial if you want to learn how to manually install it.

All the Galaxy S4 Zoom devices should automatically receive the new Android OS update, but not all are getting the firmware at the same time which is why you might want to use our tutorial below in order to apply the installation. More info about this release can be found here.

Read the guidelines below before starting the updating process:

  • use this post only with the Samsung Galaxy S4 Zoom device model number SM – C101.
    – do not attempt to update any other devices with the files that you will find in this post in case the C101 model number is not listed.
    – check the model number under Settings> About device menu.
  • install the Samsung USB Drivers on your computer.
  • enable USB Debugging from Developer Options menu.
    – Developer Options also has to be enabled at first.
    – info here on how to enable USB Debugging and Developer Options options.
  • disable KIES and any antivirus apps from running on your computer.
    – these applications might attempt to block ODIN3 v3.09 from installing the new official update.
  • if your Galaxy S4 Zoom is rooted, then this update will revoke its root access.
    – in case you have a custom Recovery it will be replaced with a stock Recovery.
  • if your device runs a custom ROM, then the update can be installed but you will lose data from its system partition.
    – also, users with custom ROM’s installed on their devices will be forced to apply a ‘factory reset’, more info is listed at the end of this article.
  • save data from installed apps using Helium app for Android.
    sync Contacts info with your Gmail account.
  • check your battery charge level and make sure that it is over 50%, it will prevent the device from switching off during installation.
  • do not blame Android.gs in case you brick the device nor in case you end up losing any important data in the process.
  • read the whole guide and make sure that you won’t skip any steps.

Now that you’ve read all of the above you can now continue to the next part of this article.
