[IDEA] Add a few preparations before run in README

[Urgarth]

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:

1. 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!

2. 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.”
3. Restart the ADB Server: Restart the ADB server by executing the following commands:

adb kill-server
adb start-server

4. Tap Allow on your device to approve the debugging request.
5. Check device authorization again:

adb devices
List of devices attached
4df798d76f98cf6d        device

6. Now you can run AdbFileManager.exe and start working.

Very good idea!
Just had the same issue with my Samsung S23 - couldnt get it to work - so came here because I knew someone had the same problem most likely.

Would be great to have a small popup explaining what to do and than some sort of "loop" which checks if they device is accessible. Otherwise this tool will never be usable by "the masses" if those need to handle things in CMD :D
