I find it hard to believe that Bitmain would send you a defective dusty unit. On top of that i find it hard to believe that they would send you an upgraded S1 instead of an S3 like you ordered something is not right there. I would contact them and ask whats up.

you should not have hard time to believe that - it is what it is, I sent you full explanation in pm as this thread is not bitmain related and this conversation is offtopic.
