In this tutorial we'll show you how to manually install the Android 4.4.4 OTA file on your Nexus 5. When a new Android update is released it never takes long to appear on the Google Developer's page as factory images and binary files. Using these generally means wiping your device though, so waiting for the over the air file to appear is a better option for some. However, waiting for it to arrive can take days, so flashing it manually is a much quicker option. Flashing an OTA file also means that all of your data and apps are untouched, along with any custom recovery or root. Here's how to do it.

To do this process you need a couple of things:
ADB Tools installed on your computer (direct download from us).
Android 4.4.4 update for your Nexus 5 (direct dwonload from Google)
Now, you're getting the KTU84P firmware update specifically for a Nexus 5 running Android 4.4.3 KTU84M. If you do not have this installed already (go to Settings > About Phone > Build Number to check), make sure you get it first.
Once you've downloaded the firmware to your computer you'll want to rename it something convenient like Android-444-OTA.zip and move the zip file to the same folder that ADB Tools are in. Ensure you have USB Debugging enabled in Developer Options first and as always, if you're at all concerned, back up your apps and data beforehand just to be safe.
How to install Android 4.4.4 on the Nexus 5
1. Turn off your Nexus 5.
2. Press and hold Volume Down and Power until you see the Fastboot screen.
3. Use the volume buttons to highlight ''Recovery mode'' and press Power to confirm.
4. Using the volume buttons again, highlight ''Apply update from ADB'' and press Power.
5. On your computer, hold Shift and right click in a blank area of the ADB Tools window (in Windows Explorer). Select ''Open command window here''. This will open the command prompt window.
6. Connect your Nexus device with a USB cable.
7. Go to the command prompt window and enter the following (using the file name of the OTA zip, whatever you chose to call it):
adb sideload Android-444-OTA.zip
8. Wait for the install to complete and your Nexus 5 to reboot.
If you have any issues, you can then do a factory reset before restoring your apps and data.
