You may find that you need a file called iap4e.bin in order to update/upgrade the firmware on your Duet2 control board. I know of at least two people who have had this problem.

Here is a github link to an older version of the firmware which does include this file. Simply put it in your duet file system and proceed with the update:
I hope this helps.
I think the most recent versions (if there were even any changes, i'm not actually sure) can be found in the last 1.x version release. 1.21
