I pulled my puck out of the drawer for the first time in a while today and connected it. I was prompted to update the firmware (I'm on a Mac, using the WebIDE on Chrome).
It failed to update saying "Error: The state of the DFU process does not allow this operation". Subsequently it won't connect (when I connect the battery no LEDs light up).
I can put it into bootloader mode but it won't connect to the laptop anymore (nor will it work with nrf Connect on my Android phone).
I tried a hard reset but even after holding the button, the green LED goes off after a couple of seconds and nothing else happens.
Does anyone have any suggestions?
