Detailed Fastboot Commands Explanation and Cheat Sheet

Have you used Fastboot commands before? If so, then you’ll know what an amazing tool it is for Android smartphones. If not, then at least you would have words like ADB and Fastboot mode thrown around. ADB and Fastboot are essential tools for Android used by developers and Android enthusiasts.

These tools will help you perform numerous different command-line operations using a PC. Fastboot and ADB are a part of the SDK Platform-tools that will facilitate debugging and modifying Android handsets using the command terminal on a PC.

What do you mean by Fastboot?

Similar to ADB, Fastboot is a command-line tool and a protocol for Android devices. It will work as a communication bridge between your PC and Android smartphone. These commands will work when the Android device is booted into the Fastboot mode.

Using these commands, you’ll be able to reboot the bootloader, enable/disable OEM unlock, modify partitions, and flash factory images. Whether you’re looking to flash a custom recovery or stock firmware images on your Android handset manually, you will have to execute Fastboot commands.
