If you’re here then it means that you are about to perform a tweak on your Google Pixel 3 XL. We know that because the fastboot mode is required during specialized operations or customizations, which mean that you either wish to learn more about the fastboot environment, or are on your way to modify some built-in settings and features. Anyhow, in order to assist you we decided to bring a detailed tutorial during which we will talk about the methods that can be followed for being able to reboot your new Google Pixel 3 XL into fastboot mode.

This is going to be a complete tutorial as during the guidelines explained we will shortly describe what you can do from fastboot mode, why and when this environment will be required, how it is related with other built-in Android mods and the risks that might be involved when operations are performed via fastboot mode. Also, we will remember the pre-requisites that should be considered before you choose to follow the reboot methods that are explained in the end.

Fastboot mode is the same thing with bootloader mode. It is also similar with the recovery environment as both mods are offering access to the Android core system that runs on your Google Pixel 3 XL. Mainly from fastboot you can obtain essential information about your smartphone – you can get data about the hardware components and some particular info about the software platform. Moreover, fastboot mode will put your device into a dedicated environment which will make your handset recognizable by third party programs and similar other tools that are usually operated from a computer.

Thus, we can conclude that the fastboot mode will be required during manual operations such as: manually installing a new Android update; downgrading your Google Pixel 3 XL to a previous built of Android OS; installing a custom recovery image; unlocking the bootloader; gaining root access; similar other tweaks, customizations and optimizations.

The fastboot mode runs by default on your Google Pixel 3 XL. However, it cannot run at the same time as the Android mode and that’s why you can access fastboot only after a dedicated reboot process is initiated (it is a ‘hidden’ menu that cannot be reached from general settings). Putting your phone into this environment can be done without having to worry about anything else – it is an official operation supported by your OEM, you don’t have to use complex and risky tools and programs, you don’t have to worry about losing your phone’s warranty and you won’t lose access to built-in apps.

But, a backup should be considered because some operations that can be initiated from fastboot mode can wipe the files that are stored on your Google Pixel 3 XL. So, it’s important to be precautions – just choose to secure your contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, IMEI / NVRAM data and other files that weren’t there by default. Such a backup can be applied in different ways: for example you can use an external storage device; you can also use dedicated apps (already tested ones) from Google Play; of course, you can choose to sync your files with your Google Account; or you can just run built-in cloud storage services.

Don’t forget to take a look over your phone’s battery power before starting one of the following reboot solutions. It will be important to ensure enough power on your Google Pixel 3 XL as if a sudden shut down happens you will risk bricking your Android device – severe software related issues can cause malfunctions if you’re not careful enough. As a general recommendation you should plug in the charger if the lower left is currently lower than 50%.

Reboot Google Pixel 3 XL into Fastboot mode

Method 1 – do it by using hardware buttons

  1. First of all, switch off your Android device: press and hold the Power key until the shut down process is completed or press the Power key once and choose ‘power off’.
  2. Then, press and hold the Volume Down and Power buttons together.
  3. Keep holding down these keys until the Fastboot mode is displayed.
  4. And that should be all.

Method 2 – do it by executing a dedicated adb command

Another way in which the fastboot mode can be entered on the Google Pixel 3 XL is by using a computer. From there you will have to initiate a dedicated adb command, so Android SDK must be installed first: learn how to install Android SDK on Windows or how to set up ADB on MAC OS X / Linux. Also, don’t forget to set up the right drivers for your smartphone on your PC. And, after doing all that, on your handset enable USB Debugging option from Developer Options. Hint: gain Developer Options by tapping repeatedly on Built Number – do it until the ‘you are a developer’ message appears. When done, follow:

  1. On your computer navigate towards the Android SDK folder.
  2. Connect your Google Pixel 3 XL with your computer via USB cable.
  3. From Android SDK open a cmd window: press and hold the Shift keyboard hotkey and then right click on any blank space; in the end pick ‘open command prompt window here’.
  4. In this cmd window type ‘adb reboot bootloader’ and press Enter.
  5. Your Android device should automatically reboot into fastboot mode.

Method 3 – download and run a dedicated app from Google Play

The easiest way to enter fastboot mode is by using a third party app available on Google Play. There are different solutions from where to choose so you have nothing to worry about – for example you can try the Quick Boot software. Just install the app on your device, run it and follow on-screen prompts for entering the desired mode. And that’s all.


These three methods will always work for entering fastboot mode on the Google Pixel 3 XL (it will work even if your phone was already tweaked). So, bookmark this step by step guide as you might want to use it later, when dealing with other customizations and optimizations.
