Those who want to enter fastboot mode on Google Nexus 5X devices probably want to install updates or unlock the bootloader. Without the fastboot mode operating, you cannot perform either of those two actions on your device. Most smartphones running Android out there in the world come with a fastboot mode. The way in which you access that fastboot mode differs between handsets, while some devices don’t let you access fastboot mode at all. With regards to the Google Nexus series of devices, accessing the fastboot mode is typically very easy.

If some of you have no idea what I’m talking about when I say fastboot mode, it might be because you have previously known this as the bootloader mode. Both names essentially mean the same thing and are just different words used for the same mode.

REQUIREMENTS

• The following guide to boot Google Nexus 5X into bootloader mode is made for exactly that: that Google Nexus 5X device. These steps won’t necessarily work for all devices, so it’s best you look up a unqiue guide for your device unless you know this guide does work for you.

BEFORE WE BEGIN

• People are usually accessing bootloader mode on Google Nexus 5X devices for various reasons. Those of you who are looking to unlock the bootloader should backup the data beforehand using your Helium app or the built-in backup feature.
• Those of you with the bootloader unlocked and with root access can install the Quick Boot application that is available from the Google Play Store instead. The Quick Boot app is great for booting into just about any mode you might need, including the recovery mode on your device.
