I am sorry Darren, but it just won't work
We went back to 6.2, and we did again the 6.3 upgrade procedure exactly as you described above.
We waited even 5 minutes before powercycling the unit. But still the same problems:
After the upgrade the Atem goes into its factory default settings, resulting in the default IP address, default videosettings (1080 60Hz) etc... and no way to change the IP address with USB. He simply forgets its address.
We spend quite some time now with this upgrade procedure without results. In the past we never had any issues relating to upgrade procedures.
For your information here is our setup:
ATEM 2 M/E Production switcher serial 846604, purchased March 2012. ( I think it was one of the first units available in Europe)
By the way the upgrade to 6.3 on our 4K switcher did not give any problems. It looks like the older switchers have this problem. I hope you can find the solution as we are not planning to say goodbye to our 'good-old' 2 M/E ATEM
