Yesterday I mentioned extracting BLOB data from Manifest.db, which would be a painful process to do manually. Thankfully, Adrian Leong (@Cheeky4n6Monkey) wrote a python script to automate BLOB extractions from SQLite databases. It is a fairly simple script and will work on any SQLite databases, not just the Manifest.db.
An example of the script is below:
python sqlite-blob-dumper.py targetdb.sqlite tablename outputdir
Test it out. Let him know what you think or submit a pull request with your updates.
