For my case (S21 Ultra), I couldn’t display files on the device after launching the program. It showed just a blank slate, even though USB debugging was enabled. After further investigation, I realized that the issue was related to the device no longer being authorized on ADB for some reason. Here are the steps to resolve it:
Navigate to the folder with our software and open the Command Prompt (CMD) there:
adb devices
List of devices attached
4df798d76f98cf6d unauthorized
If you see “unauthorized,” it’s our client!
Revoke USB Debugging on the phone: If the device is shown as unauthorized, go to the developer options on the phone and click “Revoke USB debugging authorization.”
Restart the ADB Server: Restart the ADB server by executing the following commands:
adb kill-server
adb start-server
Tap Allow on your device to approve the debugging request.
Check device authorization again:
adb devices
List of devices attached
4df798d76f98cf6d device
Now you can run AdbFileManager.exe and start working.
