autopsy and andriller

Dear all,
i am testing autopsy 4.17 and andriller.
I acquired an android samsung cell. Now with autopsy I opened a the backup.ab file, but I have not result
can someone help me?

Hello. Have a look at Android ADB backup and Analysing (no-root) android backup.ab files. You will need to convert the .ab to a format that Autopsy can understand. In the past I’ve used Android Backup Extractor for this.

ok, thank you many thanks
