Nexus devices are the perfect playground for modders, tweakers and custom ROM fanatics, and none more so than the legendary Nexus 5. Before you do any of that you'll first need to unlock the Nexus 5 bootloader, and we're here to show you how to do just that. The steps are the same, whether you're on Android Lollipop or Marshmallow.
Note: Unlocking the Nexus 5 bootloader will wipe all of the data from your device, so make sure you have a full backup of your Nexus 5 contents before you proceed. Be aware, too, that an unlocked bootloader also makes your phone less secure if it is lost (because you can bypass any security you might have set up).
To unlock the Nexus 5 bootloader you'll need part of the Android SDK called Platform Tools. You can download the full Android SDK if you like, or just the bit you need for this tutorial: download ADB Tools.
- Make sure your Nexus 5 battery is charged.
- Make sure you have a backup of your Nexus 5 data
- Ensure you have Nexus 5 drivers installed on your computer
- Ensure you have USB Debugging enabled on your Nexus 5

What can I do with an unlocked bootloader?
Many, many things. You might want it to install a custom recovery on the Nexus 5. You can also use it to flash custom ROMs (alternative versions of Android). Or you can use it to grant yourself root access and take complete control over your device.
You'll still get OTA Android updates though (unless you flash a custom ROM) and Google is nice enough to say that unlocking your Nexus 5 bootloader "may" void your warranty, not that it definitely will. After all, Nexus devices were originally designed as developer tools for Android development. Enjoy your unlocked bootloader and hit us up with any questions below.
If the command you entered doesn’t seem to work, type in the following command to see if ADB is functioning properly:
You should see a version number for the Android Debug Bridge (ADB). That means ADB is working.
Next, type in the following:
You should see your Nexus 5 appear in a list (don't worry if you don't understand the numbers). If it doesn't, ADB is not recognizing your Nexus 5. Make sure USB Debugging is enabled and you have the USB drivers installed on your PC and try again.
