The Google Nexus 10 tablet has received the official Android 4.4.3 KitKat KTU84L firmware update and you can use this tutorial in case the OTA Update notification message hasn’t arrived in your region just yet.

With the new Android 4.4.3 KitKat KTU84L you will get bug fixes, a more stable environment and better battery life out of your Nexus 10 tablet. Before starting the updating process you will have to take a look at the preparation guide as that will teach you how to correctly setup your Nexus 10 tablet.

Here’s what you need to know in order to successfully complete the updating process to Android 4.4.3 KitKat:

  • use this post only with the Google Nexus 10 tablet.
    – do not attempt to update any other devices with the files that you will find in this post.
  • the Nexus 10 tablet has to run on the Android 4.4.2 KitKat KOT49H firmware version.
    – you cannot flash the update zip file on any other firmware that is older than KOT49H KitKat 4.4.2.
    – check the firmware version in Settings> About Device> Build Number.
  • the tutorial will work for locked and unlocked bootloader, both rooted and non-rooted devices.
  • in this post you will find two guides: one that has to be used on Nexus 10 with stock Recovery and the other on Nexus 10 with custom Recovery.
  • in case your Nexus 10 runs on a custom ROM then you need to know that the update is not possible.
    – if you want to update the tablet then you will be forced to restore the tablet to stock Android 4.4.2 KOT49H first.
  • make sure to configure the Android SDK on your computer.
    – download from here.
    – extract the Android SDK on your computer’s C: partition.
    – after the SDK is extracted you should launch the SDK Manager exe and complet the installation.
    – make sure that you find the ‘platform-tools’ folder as that’s where you will be placing the Android 4.4.3 update zip file.
  • enable USB Debugging from Developer Options.
    – if Developer Options doesn’t show up in Settings, then go to ‘About Device’ and next tap seven times on the ‘Build Number’ section.
  • use this post only if you’re an advanced Android user, do not blame us in case you brick the tablet nor in case you lose any data in the process.
  • check your tablet’s battery charge level and make sure that it is over 40%, this will prevent it from switching off in the middle of the updating process.

These were all the guidelines that you had to go over in order to correctly configure the tablet for the updating process.
