Hi Folks,

I have a set of S9s batch 14.  Decided to upgrade the firmware on one of the units and it now takes 20 mins to come up.  Any mining changes seems to take 20 mins to kickin. Doesn't seem to be the most stable thing in my miner.

Anyone know were to get the older S9 firmware??  Bitmaintech only lists the latest to download....

thanks!!!
