As I said, it depends on how many versions you are going backward. There are changes made in the database and I have triggered an involuntary factory reset when I tried installing a much older version of the firmware. The main issue was the changes in how the user record was handled which—I think—caused the user record from the newer firmware version to look like a corrupted user record. Sadly, the person who could likely help most with this discussion is no longer with us.
