I got my Mesh boards yesterday and immediately started messing around with them leading through some magic to entering the DFU mode on my Argon. Do I have to flash a firmware now no matter what or can I just somehow exit the DFU mode? I tried turning the board off and on again, resetting etc, but it just keeps blinking yellow at all times, even right after power-up.
These are my first particle boards (my experience is mainly with Arduino) so if I could avoid manually flashing the firmware, I would.
We had some similar reports recently and I suspect they are due to he factory hybrid firmware hasn't been replaced with the actual modular firmware, can you try the suggestions here
