MCX8000 Firmware Update: How long does it take?

I am setting up my new MCX8000 and updating to FW version 2.1. Everything has completed except the control MCU which is still showing as downloading. How long does this typically take? It seems to be taking a long time and shows no progress on this step yet. Please advise. Thx!

It’s been much longer than that. Any idea what I can do? Thx

The Cue button do not flash ! I have did everything esle.
