====== IT9919 Hacking - part 3 - Hacking Upgrade Files ======
In this series I will be hacking around with the IT9919 media processor that powers the Lenkeng LKV373 HDMI Extender Device and the EZCAP 283S which were reviewed in previous videos.
In this video I will dig deep into the upgrade firmware files to discover if there are ways we can manipulate them to gain control of the processor.
