How long to complete K3 "master reset?"

[K1LI]

I pressed and held the K3 power switch until the "MCU LD" message appeared -
that was over a half-hour ago. How long should this take to complete?

Trying to solve the "low sub RX audio" problem.

Pressing and holding the Power button forces the K3 MCU into a "boot load"
state, not "master reset".  You now need to reload the MCU firmware.

Or you can remove power from the K3 (I pull the power connectors off the
back of the radio), wait 20 seconds or so, and then plug it back in.  

You may still have firmware loaded.

But the radio is going to sit in MCU LD state until it either receives a new
firmware load or you cycle the power.

You now need to load the MCU firmware.  The message indicates the MCU is
ready to load, or is loading, from the serail (RS232) port.
