How to unlock bootloader on Google Nexus 5X [Guide]

Google Nexus 5XIn Android, the bootloader is code that runs before the device boots the operating system. Within that code is the instructions on how to boot the operating system kernel. The bootloader instructs your kernel to boot normally if left untouched. We must modify this boot sequence if we want to get root access and install la custom ROM on our Google Nexus device.

The following guide will teach you how to unlock bootloader on Google Nexus 5X. The guide to unlocking the bootloader on Google Nexus devices is always similar. Each Nexus device has a different key sequence you must press to boot the device in bootloader mode. For example, the Nexus 4 needs the Volume Down and Power keys pressed down at the same time to get into the bootloader mode, whereas the Google nexus 10 needs you to press the Volume Up + Volume Down + Power buttons to get in the bootloader mode. When we refer to the bootloader mode with Google Nexus smartphones and tablets, we are talking about the same mode that is known as fastboot mode. Moreover, those of you with Samsung devices will know this mode as download mode. All three modes allow us to do the same thing.


  • The following guide for unlocking the Nexus 5X bootloader is made for the Nexus 5X only. Do not follow these steps on a different nexus device, including the original Nexus 5. While some guides we write could match up with other devices, it’s best to research a guide for that specific device instead to avoid unnecessary risks.
