When your phone becomes unresponsive or stuck in a boot loop, it can be a frustrating experience, especially if you’re not sure how to fix it. This condition is commonly referred to as a “bricked” device. Fortunately, there’s a way to potentially revive your phone using Android Debug Bridge (ADB). In this article, we’ll delve into the world of ADB and explore how you can use it to unbrick your phone.
Understanding ADB and Its Role in Unbricking
Before we dive into the process of unbricking your phone, it’s essential to understand what ADB is and how it works. ADB is a command-line tool that allows you to communicate with your Android device from your computer. It’s a part of the Android SDK (Software Development Kit) and is used by developers to debug and test their applications. However, ADB can also be used to troubleshoot and repair issues with your device, including unbricking it.
How ADB Works
ADB works by establishing a connection between your computer and your Android device. This connection allows you to send commands to your device, which can then be executed. ADB uses a client-server architecture, where the client is the computer and the server is the device. When you connect your device to your computer using a USB cable, the ADB client on your computer can communicate with the ADB server on your device.
Requirements for Using ADB
To use ADB to unbrick your phone, you’ll need to meet certain requirements. These include:
- Having a computer with ADB installed
- Having a USB cable to connect your device to your computer
- Enabling USB debugging on your device (if it’s not already enabled)
- Having the necessary drivers installed on your computer
It’s worth noting that if your device is completely bricked, you may not be able to enable USB debugging. In this case, you may need to use other methods to revive your device.

Step 2: Enable USB Debugging (If Possible)
If your device is not completely bricked, you may be able to enable USB debugging. To do this, go to your device’s settings and look for the “Developer options” menu. In this menu, you should see an option to enable USB debugging. Enable this option and confirm that you want to allow USB debugging.
Step 3: Connect Your Device to Your Computer
Once you’ve enabled USB debugging, connect your device to your computer using a USB cable. Make sure that your device is recognized by your computer and that ADB is installed.
Step 4: Open a Command Prompt or Terminal Window
To use ADB, you’ll need to open a command prompt or terminal window on your computer. You can do this by searching for “cmd” in the start menu (on Windows) or by using Spotlight to search for “Terminal” (on Mac).
Step 5: Verify the Connection
Once you’ve opened a command prompt or terminal window, you can verify the connection to your device by typing the command “adb devices.” This command should list your device as connected.
Step 6: Use ADB Commands to Unbrick Your Device
If your device is listed as connected, you can use ADB commands to try and unbrick it. The specific commands you’ll need to use will depend on the condition of your device and the cause of the issue. Some common commands include “adb reboot” to reboot your device, “adb sideload” to sideload a ROM or update, and “adb shell” to access the shell of your device.
Using ADB to Flash a ROM or Update
One of the most common uses of ADB is to flash a ROM or update. This can be done using the “adb sideload” command. To use this command, you’ll need to download the ROM or update you want to install and place it in the same directory as the ADB executable. You can then use the command “adb sideload
Troubleshooting Common Issues
While ADB can be a powerful tool for unbricking your phone, it’s not always a straightforward process. There are several common issues you may encounter, including:
- Device not recognized: If your device is not recognized by your computer, you may need to install the necessary drivers or try a different USB cable.
