After replacing the battery and reassembly of the doorbell, my 1st Gen wired Nest Hello Doorbell is stuck in a Boot Loop. The blue light never pulses indicating ready to connect to the local network. The blue light surrounding the doorbell button lights momentarily and then the green LED at the top of the unit flashes, the blue light goes out and the process repeats endlessly. This happens both when hardwired to the transformer and when the USB port is used. Has anyone seen this behavior?
