How To Articles

Unlocking a locked phone using the command prompt may seem like a daunting task, but with a little know-how and some patience, it can be done. In this article, I will guide you through the steps to unlock your phone using the command prompt, sharing my personal experiences and insights along the way.

Disclaimer: Proceed with caution

Before we dive into the process, it’s important to understand that unlocking a locked phone may violate the terms of service and warranty of your device. Additionally, unlocking someone else’s phone without their consent is illegal and unethical. Make sure you have the legal rights to unlock the phone you are attempting to access.

Step 1: Enable USB debugging

The first step in unlocking a locked phone using the command prompt is to enable USB debugging. This feature allows your computer to communicate with your phone via the command prompt. To enable USB debugging, follow these steps:

  1. Go to your phone’s Settings.
  2. Scroll down and tap on “About phone”.
  3. Find the “Build number” entry and tap on it seven times. This will enable developer options on your phone.
  4. Go back to the main Settings page and tap on “Developer options”.
  5. Scroll down and enable USB debugging.

Enabling USB debugging may vary slightly depending on the make and model of your phone. If you’re having trouble finding the option, refer to your phone’s user manual or search online for specific instructions.

Step 2: Install ADB and Fastboot tools

ADB (Android Debug Bridge) and Fastboot are command-line tools that allow you to communicate with your Android device from your computer. To install these tools, follow these steps:

  1. Download the ADB and Fastboot tools package from the official Android website.
  2. Extract the downloaded package to a folder on your computer.
  3. Add the folder containing the ADB and Fastboot tools to your system’s PATH environment variable.

Adding the tools to your system’s PATH environment variable will allow you to run ADB and Fastboot commands from any directory on your computer.

Step 3: Connect your phone to the computer

Now that you have enabled USB debugging and installed ADB and Fastboot tools, it’s time to connect your phone to the computer. Use a USB cable to establish the connection.

Step 4: Unlock the phone using the command prompt

With your phone connected to the computer, open the command prompt and navigate to the folder where you extracted the ADB and Fastboot tools.

Next, enter the following command to check if your phone is properly recognized:

adb devices

If your phone’s serial number appears in the list of devices, you’re good to go. If not, make sure you have correctly installed the ADB and Fastboot tools and that USB debugging is enabled on your phone.

Once your phone is recognized, enter the following command to unlock it:

adb shell input text [unlock code]

Replace [unlock code] with the actual unlock code for your phone. If you don’t know the unlock code, you may need to search online for instructions specific to your phone model.

After entering the command, your phone should unlock, granting you access to its contents.


Unlocking a locked phone using the command prompt can be a useful technique when done responsibly and legally. By enabling USB debugging, installing ADB and Fastboot tools, and following the steps outlined in this article, you can gain access to your locked phone.

Remember to proceed with caution and ensure you have the legal rights to unlock the phone you are attempting to access. If you are unsure or uncomfortable with the process, it’s always best to seek professional assistance or contact your device manufacturer for support.
