I just got notification from Hashfast (72h wait) telling me they will send me a new board and they will update me with the tracking number. It looks like they don't even want me to send back my botched board (which I think is great)
My understanding is that the procedure is we send you a label for the return board FIRST. Then you ship your board back, THEN we ship a replacement ASAP. I am not aware of any procedure where we ship one out first.
