Manual Update for Nexus 4 to Android 4.4.4 KTU84P from Android 4.4.3 KTU84L

Google Nexus 4 just got a brand new small Android 4.4.4 KitKat upgrade and you can use the instructions listed in this post if you want to learn how to successfully install it manually.

This tutorial should be used by Nexus 4 users that are still waiting for the official OTA KTU84P KitKat 4.4.4 firmware update to arrive for their device. Before starting the updating process you should first take a look at the guidelines below, so you will learn how to properly setup the device in order to complete the tutorial at your first attempt.

Here’s what you need to know:

  • use this guide only with the Google Nexus 4 smartphone.
    – don’t attempt to flash any files you find in this post on any different Android device.
  • the Nexus that you’re about to update to Android 4.4.4 KTU84P needs to be on the Android 4.4.3 KTU84L firmware build.
    – don’t use this guide in case you’re running older variants of KitKat.
    – check your device’s current firmware version by going to Settings> About Phone and then see what it says under ‘Build Number’.
    – continue with the rest of the process only in case under ‘Build Number’ is listed KTU84L.
  • it doesn’t matter if your device is running on an unlocked or locked bootloader,
  • the tutorial works with both rooted and non-rooted Nexus 4 devices.
  • this post contains two methods of installing Android 4.4.4 KTU84P update on your Nexus 4: one that is destined for users with Stock Recovery and another one for Nexus 4 with custom Recovery like CWM or TWRP.
    – note: the current OS has to be stock not a custom ROM.
  • if your Nexus 4 runs on a custom ROM, then you need to know that this updating process will not work and you will first need to restore the phone to a stock ROM via Factory Image.
    – Factory Image installation on a Nexus device will wipe every single data file in the process.
  • make sure to configure the Android SDK bundle on your computer before starting the update.
    – get it from here and extract it on your computer’s C: partition.
    – after you unzip Android SDK you need to launch its SDK Manager exe program. Install all the required tools and drivers, then test to see if your device is detected by your computer.
    – in the SDK directory you should look for the ‘platform-tools’ folder, leave it open as that’s where you will be placing the Android 4.4.4 KitKat update zip file.
  • in case the Nexus 4 is not detected by your PC, then you can choose to install the Nexus 4 USB Drivers from this tutorial here.
  • make sure to have the USB Debugging enabled from Developer Options.
  • this is a tutorial that is destined to be used by advanced Android users.
    – don’t try to update your phone in case you’re a beginner.
  • check the phone’s battery power 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 important data in the process.
  • continue to the next tutorial only when you’re sure that you know what you’re doing.
  • read the entire guide and make sure not to skip any steps in the process.

Now that you know all of the above you can continue to the next part of this post.

How to flash Android 4.4.4 KTU84P for Nexus 4 running Android 4.4.3 KTU84L (ADB Sideload Stock Recovery Method):

  1. Download the Android 4.4.4 KitKat update from here or here.
    – save the file on your computer.
    – you should change its name to ‘update.zip’
  2. Move the update.zip file in the ‘platform-tools’ folder of the SDK directory.
    – that’s a folder created by Android SDK.
  3. Switch off your Nexus 4 completely.
  4. Now boot it into Recovery Mode.
  5. When you’re in Recovery Mode you should select the option named ‘apply update from adb’.
  6. Use the USB cable and connect your Nexus 4 with your computer.
  7. Open the folder where you’ve placed the ‘update.zip’ file.
  8. Press and hold ‘SHIFT’ key and, at the same time, you need to right-click on the folder’s white space. Select ‘open command window here’.
  9. In order to begin the installation of Android 4.4.4 KitKat KTU84L you need to enter the following line in the command prompt: adb sideload update.zip
    if you didn’t change the file’s name then you need to enter the exact name for the update to start.
  10. Now the update process should be running and you need to wait until Android 4.4.4 KitKat is installed successfully by your phone.
  11. When the progress bar reaches 100% and you see the Stock Recovery options you should select ‘reboot system now’.
  12. Wait for the phone to boot in normal mode and then log into its home screen.

That’s it, you should now be running the latest Android 4.4.4 KitKat on your Nexus 4.

If your phone is stock Android 4.4.3 KTU84L, but it runs with a custom Recovery, then you can use the second tutorial below.

Install Android 4.4.4 KTU84P for Nexus 4 with Custom Recovery:

Use this tutorial with custom Recoveries such as TWRP or CWM, but make sure that you haven’t used the custom Recovery to flash anything on your device, as the phone still has to be on an intact Android 4.4.3 KTU84L firmware.

  1. Download the Android 4.4.4 KTU84P from here or here.
  2. Connect the Nexus 4 to your PC via USB cable and move the firmware update zip to its internal storage.
  3. When the files are moved successfully you should disconnect the phone from PC and then power off the device.
  4. Boot your Nexus 4 in Recovery Mode.
  5. Select ‘install zip from sdcard’ for CWM or tap on the ‘Install’ option for TWRP.
  6. Find the ROM zip file and confirm its installation.
  7. Wait for your smartphone to complete the update and then reboot the system in normal mode.

These were all the instructions that you had to follow in order to complete the updating process for your Nexus 4 to Android 4.4.4 KTU84P.
