Just to confirm what JoeySmyth has stated here, this is not a typo. I experienced the same problem when I rolled back to version 1.16.13 and I was quite alarmed that the update screen was showing the firmware as v.3.16.13
Thinking about it logically for a few moments though I soon realized that the SMP could not update to an older version which is why it has to show v.3.16.13
Take it from Joey, it will work so nothing to worry about. It worked just fine for me and once you’ve rolled back your firmware will show as v.1.16.13
