A flashing setting number usually means the power board and front board aren't communicating. Heads-up: the 621991001 kit is for the N611/N811, not the N821. The N821 takes the 637779 kit (serials below 9126825) or the 628661 power board (above that). Double-check which board went in, and send us your serial number so we can confirm.
