Wondering if anyone has the firmware from the beginning of 2011. I updated to the firmware from Jun 2011 as soon as I received it, and downloaded the previous firmware that was linked in case I wanted to backout, but I somehow managed to download the wrong firmware (the one with -CA in its model). The one I want is no longer available from Insignia because they only keep the last 2 versions and there are at least 2 new versions since then. I need the older firmware so that I can enable the region unlock menu. Thanks a lot in advance.
