We're all here to help each other - and to give back to the team.
We've been doing this for decades - as we're kind hearted helpful people.

Helping you has taught me things as I've never used "adb backup" myself.
Never even heard of it.

It's GREAT that you resolved the question of extracting (and restoring?)
Wi-Fi passwords on older Androids (which didn't lock WifiConfigStore.xml).

I'm trying to reproduce steps but I'm not sure the sequence on Android 13.

 C:\app\editor\android\scrcpy> adb backup
 WARNING: adb backup is deprecated and may be removed in a future release
 adb.exe: backup either needs a list of packages or -all/-shared

 C:\app\editor\android\scrcpy> adb --version
 Android Debug Bridge version 1.0.41
 Version 33.0.3-8952118
 Installed as C:\app\editor\android\scrcpy\adb.exe

Looking it up, I see there is an Android backup-and-restore guide.
 <https://github.com/eviabs/Android-Backup-and-Restore-Guide/blob/master/Android%20Backup%20and%20Restore%20Guide.md> 
 "An *.ab backup contains all your personal and hidden data of your app. 
  It doesn't necessary contain your local storage data (which is located in
  your sd card). Make sure you copy by yourself the sd card content."

 C:\app\editor\android\scrcpy> adb backup -f myAndroidBackup.ab com.grindrapp.android
 WARNING: adb backup is deprecated and may be removed in a future release
 Now unlock your device and confirm the backup operation...
 (My phone in another room popped up an unlock request, which I easily 
  accepted from Windows since I operate my phone at home from the PC.)

 C:\app\editor\android\scrcpy> dir myAndroidBackup.ab
 11/08/2024  11:40 PM                47 myAndroidBackup.ab

  C:\app\editor\android\scrcpy> adb backup -apk -shared -all -f fullAndroidBackup.ab
 (again the monitor dedicated to Android popped up an unlock request which
  I accepted from the PC as I don't feel like looking for the phone)

It's taking a while... so moving on, here's how to restore apparently.

Single app backup (the app has to actually be installed already).
 C:\app\editor\android\scrcpy> adb restore myAndroidBackup.ab

(I'm still waiting for the all-apps-and-their-data backup to finish.)
The only thing is these are restoring "apps", not Wi-Fi settings, right?

So I'm confused (although the "settings" app is just another app too).
How does this backup/restore Wi-Fi configuration settings?
