How to Fix ADB Device Unauthorized Error in 2023?

If you’re getting an “ADB device unauthorized” error when trying to connect your Android device to your computer, it’s most likely because you have USB debugging enabled on your device, but you haven’t authorized your computer to debug it.

Here’s how to fix that:

1. On your Android device, go to Settings > Developer options and make sure that USB debugging is enabled.

2. Connect your Android device to your computer using a USB cable.

3. If you see a pop-up on your Android device asking whether you want to allow this computer to debug it, tap Allow.

If you don’t see the pop-up, try steps 4-6.
4. On your computer, open a command prompt and type: adb kill-server

5. Then type: adb start-server

6. Finally type: adb devices
You should now see your device listed as “device.”

Step One: Check Debugging Mode Settings

1. Check your ADB debugging mode settings. On your Android device, go to Settings > About Phone and find the Build Number. Tap on the Build Number seven times to enable Developer Options. Then, go to Settings > Developer Options and ensure that USB Debugging is enabled.

2. If USB Debugging is already enabled, try restarting your device and/or your computer. Sometimes this simple step can fix the issue.

3. If you’re still having trouble, try reinstalling the Android SDK Platform-Tools. This will install the latest version of ADB and may fix any issues you’re having.

4. Finally, if none of the above steps work, it’s possible that your Android device has a hardware issue that is preventing ADB from working correctly.

Step Two: Replug the USB Cable

If your Android device is still showing the ADB Device Unauthorized message, try replugging the USB cable into your device and then your computer. This will often reset the connection and allow ADB to work properly again.

If your device is listed as “unauthorized”, don’t worry! This just means that you need to give ADB permission to access your device.

“adb shell”

“su”

“cd /data/local/tmp”

Once you’re in the tmp directory, type the following:

“pm grant com.android.debuggerd permission_name”

Substitute “permission_name” with the name of the permission you want to grant (e.g., “android.permission.WRITE_EXTERNAL_STORAGE”).

3. Right-click on your Android device and select “Uninstall.”

4. Confirm that you want to uninstall the driver.
