tirwit_06, I notice from our event logs that we have the same MCU, HUB1 and HUB2 firmware versions, and that it's the HUB 2 update that fails, and also that the current firmware version we have for HUB2 is 00000000 which seems a bit odd.
I wonder if it's this zero firmware version that's preventing any update being written.
Does anyone know if there's a way to "flash" and re-write the dock firmware from a blank state?
