Ring Doorbell Pro Wired

Opened but still new! Set it up and realized the wiring for the doorbell at my condo is dead. Bought for $170. Still on Amazon for $170. Accidentally opened the box from the bottom so it is taped closed. I removed the protective film before realizing there was no power. Instructions said there are two small bracket screws and two security screws, but there was only one included of each (last photos, bag C and B). When I set it up, I didn’t end up using the small bracket screws anyway and it only needs one security screw to keep the faceplate on. Open to reasonable offers!
