[Elecraft] Oops, firmware upgrade died in the middle

[Buddy Brannan]

Hi,

So I went to update my KX3 firmware, and something or another happened, and the communication died in the idle. Now the KX3 won't power up so I can try again. 

Some time ago, I remember reading an article about how to get into an emergency recovery mode to reload firmware, but I can't seem to find that article now (naturally). Can anyone point me in the right direction?
