How to Use Fastboot and ADB Commands for Beginners

If you’re into Android customization, flashing ROMs, or fixing boot issues, you’ve probably heard about ADB and Fastboot. These are powerful tools provided by Google that allow you to interact with your Android device from a computer using command-line instructions.

In this beginner-friendly guide, we’ll explain what ADB and Fastboot are, how to set them up, and cover some of the most useful commands for each.

🔍 What Are ADB and Fastboot?

• ADB (Android Debug Bridge): A versatile command-line tool that lets your computer communicate with your Android device. It’s useful for debugging apps, transferring files, installing APKs, accessing device logs, and more.
• Fastboot: A tool used for low-level modifications such as unlocking the bootloader, flashing firmware, and accessing recovery or bootloader modes. It only works when your phone is in Fastboot Mode.

🛠️ What You’ll Need

1. A Windows/Mac/Linux PC
2. An Android phone with USB Debugging enabled
3. A USB cable
4. The ADB and Fastboot drivers (also known as Platform Tools)

📦 Step 1: Install ADB and Fastboot (Platform Tools)

1. Download the official Platform Tools from Google:
   👉 https://developer.android.com/studio/releases/platform-tools
2. Extract the ZIP file to a folder on your desktop (e.g., C:\platform-tools).
3. Open the folder, hold Shift + Right Click on empty space, and select “Open PowerShell/Command Prompt here.”

🔗 Step 2: Enable USB Debugging on Your Phone

1. Go to Settings > About Phone
2. Tap Build Number 7 times to unlock Developer Options
3. Go back to Settings > System > Developer Options

If your phone is connected properly, it will show a device ID with the word “device” next to it.
