A List of Useful ADB and Fastboot Commands and their Usage

In this guide, we will be listing all the useful and most frequently used ADB and Fastboot Commands. When it comes to the custom development, then ADB and Fastboot Commands are literally the first steps in this long journey. Not just by the tech enthusiast but these commands are also being used by general users as well.

In this regard, if we talk about the basic everyday tasks where these commands are being used, then this could include the likes of opening the ADB shell environment [for carrying out tasks like uninstalling bloatware], rebooting the device to stock recovery for resetting the device or flashing firmware via ADB sideload.

Then if we turn our attention toward the technical aspects, then you could use these commands for booting the device to Fastboot/FastbootD Mode, unlocking the bootloader, flashing custom recovery like TWRP, flashing Magisk patched boot.img for rooting, and a slew of other tasks. So owing to their such a higher position in the pecking order, this guide will make you aware of some of the most important ADB and Fastboot Commands. Follow along.

The Prerequisites to Executing ADB and Fastboot Commands

Before you could execute any of the ADB and Fastboot Commands, you will first have to checkmark a few prerequisites listed below.

STEP 1: Download Android SDK Platform Tools

First and foremost, you will have to download the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide.

STEP 2: Enable USB Debugging

Next up, you will have to enable USB Debugging on your device so as to make it recognizable by the PC in ADB mode. So head over to Settings > About Phone > Tap on Build Number 7 times [MIUI number for Xiaomi devices] > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging.

STEP 3: Open CMD inside Platform Tools

1. Head over to the platform-tools folder, type in CMD in the address bar, and hit Enter.
2. This will launch the CMD window with the platform-tools folder directory.
3. You should execute all the ADB and Fastboot commands only in this CMD window.
