Apparently my use of the (Bricked?) description was confusing, and I apologize.
I am going to open a new thread with the subject "NanoVNA not recognized by computer after upgrading Firmware with DfuSe Demo SW"
I suggest that no more replies be made to this thread. Please see the new thread for any further developments.
I appreciate everyone's helpful comments and will try to be clearer in the new thread.
