Can’t get past language screen

I just picked up a new 4K box and brought it home. Plugged it in and can’t get it past the language selection screen. I’ve tried holding a and D and pressing 981, doesn’t work, as well I can’t sync it together because I need to select language first. Been in support for 3 hours, no help. Any ideas until I go back to xfinity store for another, new one....
