It might seem like a dumb question. I am being forced to manually update the brand new D6400 I just bought. The modem/router came with update 74 and when I tried to let it auto update, I got an "Unknown error:-1" so I am manually updating it. Do I have to update each release one at a time or are they cumulative updates? I mean are all previous updates contained in the new update? or do I have to do one by one.
Usually you can update all at once. Baring a changing to the partition size and then there's usually a release note stating which version you need to go to (that changes the partition) before updating the rest of the way.
