Firmware was 2.20 AQQ.0 released 04-06-2010. Tried to upgrade to 3.00 AQQ.4 released 01-30-2013. Received error errno: -42008 Firmware Not Compatible! Tried upgrade to 2.20 AQQ.1 released 05-17-2010. This was successful. Now I wonder, will the upgrade to 3.00 AQQ.4 eventually work if I apply all the preceding firmware releases in sequence? That would be 2.20 AQQ.2 released 10-01-2010 2.20 AQQ.3 released 11-05-2010 2.20 AQQ.4 released 04-25-2011 2.20 AQQ.5 released 06-29-2011 2.20 AQQ.6 released 10-11-2011 3.00 AQQ.0 released 03-02-2012 3.00 AQQ.2 released 05-08-2012 3.00 AQQ.4 released 01-30-2013
