Nexus 10 Manual Update Guide to Android 4.4.4 KTU84P from Android 4.4.3 KTU84L

The Google Nexus 10 tablet has received its own version of Android 4.4.4 KTU84P firmware update and you can use this tutorial if you want to manually install the new files without waiting for the OTA notification to arrive in your region.

This is a great guide that any Nexus 10 user can try to use if they are currently running stock Android 4.4.3 KTU84L firmware and don’t want to wait until the official Android 4.4.4 KTU84P is sent to their devices. This new update brings security fixes mostly and it prepares your device for future Android releases.

Before starting the updating process you should first take a look at the guidelines below:

  • use this post only with the Google Nexus 10 tablet.
    – don’t try to update any other different Android tablets or smartphones with the files that you will find in the tutorial.
  • make sure that your Nexus 10 tablet is running the latest Android 4.4.3 KTU84L firmware as this new 4.4.4 KTU84P build update cannot be flashed over Android 4.4.2 nor any other older firmware version.
    – check the tablet’s model number by going to Settings> About device> Build Number and if KTU84L value is listed then you can continue with the tutorial.
  • you can use this post for Nexus 10 with both locked and unlocked bootloader.
  • you can use this post for both rooted and non-rooted Nexus 10 tablets.
  • in case the Nexus 10 tablet that you’re about to update is running on a custom ROM, then you shouldn’t use this guide as you will brick its firmware.
    – if you have a custom ROM on your Nexus 10, then you will need to install a factory image in order to restore your device to stock Android and only after that you can flash an ‘update.zip’ on your device.
    – users running Nexus 10 custom ROM should stay away from this guide.
  • in this guide you can find two different guides: one teaches you how to use the Stock Recovery to flash the new update, the second guide teaches you how to use the guide on Nexus 10 tablets with a custom Recovery installed on them.
    – note that even if you have a custom Recovery like TWRP or CWM you still need to have a full 100% stock Android 4.4.3 installed on your device.
    – if you’ve applied any small modification for the installed OS, then the guide will not work and you will risk bricking its firmware.
  • install the Android SDK bundle on your PC before starting the process.
    – unzip and extract SDK to C: partition and then launch SDK Manager to update and install the required tools.
    – also, make sure to check the SDK directory for a ‘platform-tools’ folder, that’s where you will need to put the new ‘update.zip’ file, more can be found in the tutorial.
  • enable USB Debugging for your tablet from Developer Options menu under Settings app.
  • use this post only if you’re an advanced Android user, do not blame us in case you brick your device nor in case you lose any data in the process.
  • check the tablet’s battery charge level and make sure that it is over 50%, this will prevent the tablet from switching off in the middle of the updating process.
  • read the entire post, don’t skip any steps and make sure to ask for extra help in comments.

Since you’ve gone past all of the above you can continue to the next part of this post. Learn how to successfully install the new ROM update using all info listed below.

Flash Android 4.4.4 KTU84P for Nexus 10 using ADB Sideload and Stock Recovery:

  1. Download the Android 4.4.4 KTU84P zip from here.
    – the filename for this update zip is a long line of random characters, so it would be best for you to rename it to ‘update.zip’ and then continue to the next step.
  2. When the download is complete you should simply save the file on your PC in the ‘platform-tools’ folder of the SDK directory.
    – that’s the directory created after downloading the Android SDK.
  3. Power off the Nexus 10 completely.
  4. Boot your tablet in Recovery Mode.
  5. When the Recovery Mode is loaded you can select the option that says ‘apply update from adb’.
  6. Connect your Nexus 10 to your PC via USB cable.
  7. Go to the folder where you’ve placed the update.zip file.
  8. Now, press and hold SHIFT key and at the same time you will have to right-click on the folder’s white space and select the ‘open command window here’.
  9. When the Windows command prompt loads you will need to enter the following command line and start the updating process: adb sideload update.zip
  10. Installation of Android 4.4.4 KitKat will take a while and you shouldn’t press any buttons until the Stock Recovery tells you that the update was complete.
