Answered in the email. Problem solved. There was a loose part in the device. When connected properly all works great.

Hello
I'm trying to install the latest update into the AnimaPhi. Following the instruction this appears on the screen and nothing more. I've left the device for about half an hour but the display did not change.
When I try to unmount the volume it wants endlessly as well.

My system is BigSur 11.5.2

Anyone can give some advice?

Cheers
Pavel
