Hm, how do you practically extract that? I am trying to extract it from Samsung Galaxy S3. Of course /data/data and /data/system are not readable by the adb user and it would require to root the phone. But then we have one problem: even if USB debugging is enabled, you can't connect to the phone while locked to upload the new image. Another problem is that you might be required to unlock the bootloader (haven't done that so not 100% sure) which according to what I read will erase user data including the hashes.
Please correct me if I am wrong.
