If you're still wondering if you should update to KOT49H, it's definitely worth it because it brings bug fixes, a few changes and security enhancements.

The method that we are going to use in this post is the CF-Auto-Root file thanks to recognized xda-developers member - Chainfire.


Not following such procedures carefully and failing to complete it might brick your device. AndroidJunkie will not be responsible for your actions.


  • Be sure to have the USB Drivers installed for the Nexus 5 in order to be able to transfer files between the phone and computer.
  • Make sure your Nexus 5's bootloader is unlocked. To unlock the bootloader you may read this post.
  • Create a backup of all your valuable saved messages, app data, contacts and everything else you want to keep
  • Enable USB debugging on the phone by going to Settings -> Developer options. If you don't have Developer options enabled, head into Settings -> About phone - now begin tapping continuously on where it says Build number and it should say "You are now a developer".
  • Make sure you have some battery juice because if the device shuts off before the procedure is completed, you may corrupt your rom and end up with a bricked device.

    How to Root Nexus 5 running Android 4.4.2 KitKat (KOT49H):

    1. It's finally time to begin the procedure. So download the Android SDK and set it up with downloading platform-tools in SDK. If you're not sure how, you can check out this guide by TeamAndroid - Click here. 
    2. Download Fastboot and extract it in the directory android-sdk/platform-tools.
    3. Download the file to your computer.
    4. Once the file is on your phone, power it off. Now hold the Volume up + Volume down + Power buttons simultaneously to boot into Fastboot/Bootloader Mode until you see it appear on your phone.
    5. Connect your Nexus 5 to your computer with your USB cable.
    6. Extract the CF-Auto-Root files into the same directory where you extracted Fastboot and head into that directory.
    7. Now run the file run-windows.bat
    8. Now wait and watch as the process begins and follow the on-screen instructions.
    9. Once the process is done, the phone should reboot. Please note that the boot may take some time, be patient before coming to conclusions!
    If you want to be sure that you have succeeded, you may download an app such as Root Checker from the Google Play store and run the check to see if everything is alright.
