It's not entirely clear what happened in your case. How long was your breaker turned off? What exactly does "isn't working" mean? When you turned the breaker back on, you should have gotten a steady green light on your doorbell, not a flashing blue light.
Many customers have difficulties performing a successful factory reset. Instead of using a pin, can you use a paperclip, so you can more firmly push the reset button? When you do press the reset pin, this should happen:
1. Locate the reset pin hole on the back of the doorbell (above the QR code).
2. Insert and hold the pin (you can use an unfolded paperclip or a thumbtack):
At 10 seconds, the status light will blink yellow four times, and you'll hear a countdown tone.
At 12 seconds, the status light will be steady, solid yellow while the doorbell starts the factory reset, and you'll hear a confirmation tone.
3. Release the button. Your doorbell will restore to its factory settings.
4. After the factory reset, your doorbell will appear as “Offline” in the app.
