Fastboot Commands All List and Cheat 2022 Sheet with Explanation

Fastboot Commands List and Cheat Sheet with Explanation;- Have you ever used the Fastboot commands? If not, you might at least be familiar with the Fastboot mode on Android devices. ADB and Fastboot are protocols for Android meant to be used by developers and enthusiasts. They can be used to perform different command-line operations using a computer. ADB and Fastboot are a part of the SDK Platform-tools that facilitate debugging and modifying Android devices using the command terminal on a computer.

Whats is Fastboot?

Just like ADB (Android Debug Bridge), Fastboot is a command-line tool as well as a protocol on Android devices. It works as a communication bridge between your computer and Android device. Fastboot commands work only when your device is booted into the Fastboot or bootloader mode. Using these commands, you can reboot the bootloader, enable or disable OEM unlock, and flash factory images or modify partitions on your device.

Whether you want to flash a custom recovery or the stock firmware images on your Android device manually, you must execute specific Fastboot commands for the purpose. However, before you can execute ADB and Fastboot commands, there are certain preparations that you must make beforehand.


Download the Android SDK Platform-tools that includes ADB and Fastboot files and install them. The next thing you need to do is to install the Android USB driver from your device’s OEM. The last pre-requisite is enabling USB Debugging on your Android phone or tablet.

USB Debugging is located under Developer Options on your Android device. Since the Developer options are not meant for average users as they contain sensitive settings, they remain hidden by default. To enable it, go to Settings> About phone and tap the Build number 7 times. You’ll see a toast message telling ” You are now a developer!” Now, return to the Settings menu page and you’ll find Developer options on the bottom of the page.

Fastboot Mode

ADB commands just require an Android device or emulated connected via USB. However, Fastboot commands require a connected Android device that is booted in the Fastboot or Bootloader Mode. You can boot Android phones or tablets into the Fastboot mode by pressing the Volume Down + Power buttons simultaneously for 2-3 seconds. On some devices, you might need to use the Volume Up key instead.

Alternatively, you can reboot your Android device into the Fastboot or Bootloader mode using an ADB command. Connect your phone to a Windows, Mac, or Linux computer and execute the following commands one after another. Make sure your phone’s screen is unlocked.

adb devices

When you hit the Enter key after issuing the above command, you’ll see the connected device on the command window.

Having ensured a proper connection, you can execute the following command:

Your Android device will reboot into the Fastboot mode and you’ll all set to use Fastboot commands listed below.
