 I've used it to update over a dozen antennas now.
 I just had two instances (back to back) where the antenna
 was bricked by a failed update.

 I had just updated four antennas successfully, and afterwards
 I updated another one fine.    I don't have enough info logged
 to debug (the console output is attached for curiosity's sake).
