Hi, thank you so much for your help so far. It really is appreciated. :)
When I run the upload script, I get the following:
So as per the suggestion, I tried again with --force but it's been stuck like this now for about 10 minutes. (I did run it with the usb cable unplugged, then plugged it in when instructed)
pi@raspberrypi:~/flotilla-offline/firmware $ sudo ./upload --force
Flotilla Firmware Uploader
This script will reflash the current dock firmware.
This may be needed if your dock stops responding.
./upload: 26: read: Illegal option -s
Plug in your Flotilla Dock now.
Updating should continue automatically.

The PSU I'm using isn't an official one, but it is rated at 2A output. I attempted to run curl -sS get.pimoroni.com/gettingstarted | bash
but got a 404 back from that url.
Thanks again for your continued help.
