ITS-G5 Receiver Setup - Write error

[excitron]

Stuck at step "4. Apply" (don't see any mention of this step in the docs).

Is there something obvious I'm missing?

Here's the log:

Had the same issue. Fix: unplug the board and reconnect it without holding any button (especially BOOT), let it boot normally, then hit Apply — worked for me.
