Shelly Dimmer 2 Won't update or join network

This is as far as it gets.

It says it needs a firmware update. I click YES... and then that's it. Nothing ever happens.

Any ideas?

When you say 'pictures' do you mean screenshots from the app? Or photo's of the Dimmer 2? The above image is as far as it gets. It says 'Loading Preparing Device' and then that's it. No matter how long you leave it, it never gets updated, joins the network or goes any further.

Sorry, are you really asking me to make a screen by screen snapshot and add a description of every step I go through detailing every step of the process and then upload it here?

Perhaphs I can make a video for you and upload it to my YouTube channel?

The screenshot above is as far as the process ever goes. It goes no further. The Shelly Dimmer 2 does not update after I have enterd my SSID and password. It says (as the screenshot above) "Your device needs to update..." I press YES and then nothing happens even if I leave it for 10 minutes.
