New device not updating? Stuck on 7.16.0-220

Thanks to cat0w for the link and good info. Often the MCH will not do back to back OTA firmware updates within hours of each other. There was usually a built in delay period of a few days before the next update even if the next FW was available.

The dates below showed that the updates occurred about 7 days apart, even though in the MCH FW Update Instruction page it suggested it could update within a few hours.
