Nest doorbell (first gen) won't install; flashes bright blue, then dim blue, then nothing

[CP173]

The title pretty much says it.  I had to remove this wired first generation Nest doorbell to solve a different problem.  Now, it won't install.  I've done both the 10-second and 30-second factory resets, but it still won't install.

The small green light at the top flashes green twice, then the button is bright blue for just a second, then it's dim blue (possibly white).  This cycle repeats.  The app can't find the doorbell.  I think it's continually rebooting.  Pressing the button will ring the indoor chime, but only when the button is bright or dim blue.  Otherwise, nothing.

Buying a replacement is an option, but I'd like to know that this unit is beyond repair before doing so.  I greatly appreciate any help you might provide!

I'm not sure what 10-second and 30-second factory resets you're referring to. The factory reset instructions for the Google Nest Hello Doorbell call for holding down the large doorbell button and the reset pin (with a paperclip) while the doorbell is still attached to your doorbell wires, and hoping them for about 10 seconds until the doorbell chimes and its light ring starts spinning blue, and then flashing yellow, and then all the lights should turn off. The complete instructions are here:

If you followed those instructions and could not get the doorbell to reset, you could try contacting Support using the link and instructions in this post:

Thanks for the fast response @MplsCustomer  I tried the factory reset as you describe and now the top green light is flashing.  Additional attempts at reset or reboot don't work: it's just now a flashing green decoration.

I've looked around the support threads and it seems that this indicates a hardware failure.  I'm going to treat it as such and get a replacement, unless someone else comes up with a better solution.

Admin, you may close this thread.  I just bought an Arlo doorbell and am *much* happier with it.
