Steve, Other users have posted that DfuSeDemo can be unsafe to use and result in a "Dead" unit. It seems to happen infrequently, but when it does you can no longer use DfuSeDemo to revive your unit.

Do you have a ST-link V2 programmer?

I, and not only, used this firmware many times, I did not see anything like it. Try using a different computer if there is a pop-up message when a new device is detected. (close the contacts of the
