I'm having trouble updating? I've tried two different bits of hardware and get the same behaviour. Here's some brief info...
Trying the update from the menu, LED flashes a few times and then goes ON/OFF depending on state of sensor. When I attach to serial port I get a memory dump;

If I use BrewFlasher and install 2.1.0. and after a reset, when I connect I get;
404: File not found.
From the serial output I think this is the error;
2020-08-04T08:08:25Z V: Serving 404.
reported when I try and connect.
The LED flashes when beam broken and bubble count reported on serial output looks correct, not seeing the little bubble character anymore
when the beam is broken. Serial port is also still reporting version as 2.0.0.
If I downgrade from 2.1.0. to 2.0.0. everything works as before.
What other info can I provide?
