How do i recover my .usfm file from Apk

I got attacked recently and my laptop and smartphone was stolen.

My SAB project didn’t have any backup. It was just on the system and I built it with access code.

Now, i can’t access my app anymore with my new phone. Others too can’t because I can no longer generate the ACCESS CODE. I still have the APK…

HOW CAN I GET BACK MY .USFM FILES that took me a year to type? I need to start all over again.

Any solution?
