With the Breeze powered off, spin the props by hand through several revolutions. You should feel very light pulses as you do this. If any motors will not spin they are damaged.
If the motors were OK, power the Breeze on and watch for the Power LED to flash red/green/blue with a do-mi-so sound and go to flashing blue in a few seconds. At this point the Status LED in the arm near the camera should be red, several seconds later it should flash green. You should now be able to connect via WiFi.
Report the condition of the Status indicators at the top of Breeze Cam once you get to this point.
