How do I rollback the firmware version on R7000

[RichValley]

How do I rollback the firmware version on R7000? In Device Manager, not all connected devices are appearing, and I understand from other posts that the latest firmware version is the cause of the problem. How do I rollback to a previous version?

You download the version you want from the support site. 

Then simply follow the manual update process (from the manual) but use the version you downloaded.
