Natanel Ervin well, it's really not a dud. Sounds to me like you purchased something that nobody in the public should even have. Demo models don't get sold. The seller was most likely (or is socialising with) not the most honest person.
Updates etc, will most likely not work since that firmware is not updateable. The only way to get this to work is by installing new firmware which would require a reprograming of the IC's.
Long live Ed Sheeran ;-)
