I have two 7D Mark II, and updated the firmware on one of them last night, and then compared them. They both acted the same way. No problems with the firmware update.
If you read all of the posts about lock ups it seems to have been from the non US market downloads. The one guy who was having problems redid the update with the US version, and his problems went away.
I just downloaded both the Asian file and USA file. Both came from the same exact server with the exact URL.
There is no such thing as a "US version" of the firmware update.
