# adb root

# from your computer, when it's attached to your phone with ADB.
# These JPGs are just renamed very strangely.

# You also need the database to match the files to numbers.
# Exit the app completely before doing this.
# adb pull /data/data/com.tapastic/databases/tapas_room.db

# The filenames are in the table download_episode.
