The Android Debug Bridge (ADB) was a powerful tool that allows users to control their Android devices from a computer. It is used for debugging, flashing ROMs, and other advanced functions. Unfortunately, it can sometimes be unreliable, and one of the most common errors is the “ADB Device Unauthorized” error that appears when attempting to connect your device to ADB.
ADB device unauthorized error is an irritating issue that can occur when attempting to use the Android Debug Bridge (ADB) to connect your device to a computer or laptop. This error prevents users from using ADB to access their devices and can be difficult to troubleshoot.
This article will discuss the causes of this error and how to fix it. We will go through a few different methods that can be used to get ADB up and running again and ensure your device is correctly connected to your computer or laptop.
A variety of issues can cause unauthorized ADB device errors. This error usually occurs when the device is not properly connected to the computer via USB or when the USB debugging mode is not enabled. It can also occur if the USB driver is not installed on the computer or if the ADB daemon is not running on the device.
Android Debug Bridge (ADB) is a versatile command line tool that lets you communicate with and control an Android-powered device over a USB link from a computer. However, sometimes users may experience an “unauthorized” error message when they attempt to use ADB. Fortunately, this error can usually be resolved with a few simple steps. Here are the methods you need to take to fix the ADB Device Unauthorized error:

In order to fix this issue, the user must ensure that the USB cable being used is compatible with the Android device. If the cable is not compatible, it will not be able to establish a secure connection with the device. Additionally, the USB cable must be in good working condition, as a faulty cable can also cause an error.
Check USB Debugging
The first thing you should do when trying to fix an unauthorized ADB error is to check if USB Debugging was enabled on your Android device. To do this, go to the Settings menu, scroll down to the Developer Options option, and make sure that USB Debugging is enabled.
Restart the ADB Server
If you’ve checked that USB Debugging is enabled and you’re still getting the ADB unauthorized error, you should try restarting the ADB server. To do this, open the command prompt on your computer, type in “adb kill-server” and hit enter. Then, type in “adb start-server” and hit enter again.
Update Your USB Drivers
If you are trying to debug your Android device using ADB and have encountered the error “ADB Device Unauthorized,” you may need to update your USB driver. This error occurs when ADB can’t communicate with your device due to a driver issue. Updating the driver can help to ensure that your computer properly recognizes your device. This guide will show you how to update your USB driver.
- Open the Device Manager on your laptop. You can do this by searching for “Device Manager” in the Start menu.
- Locate the USB device that is giving you the error. It is usually listed under the “Universal Serial Bus controllers” section.
- Right-click on the device and select “Update Driver” from the menu.
- Select “Search automatically for updated driver software” and follow the on-screen instructions.
- Once the driver has been updated, you should be able to use ADB without any issues.
Updating your USB driver can be an effective way to resolve ADB Device Unauthorized errors. While the process is relatively simple, it is always best to consult.
