It's good for OFD to start supporing APK Downgrade Extraction. Especially when other mobile forensic tools like 4PC does not do well on this matter, OFD could boost the competitiveness as possible as they can.
Finally OFD decide to support APK Downgrade, I have to say it's late and I wonder why it took so long..it seems like "Mission Impossible"??? No kidding~ Anyway..what can I say~Better late than never~ Don't forget some mobile forensic tools still could not provide APK Downgrade method till now. Great job~ OFD!!!
