I started having problems with my D3's after updating to the latest November firmware (drop in hashrate, missing chains, etc). Anyone know where I can find earlier versions to see if it fixes the problem?
Unfortunately, Bitmain does not have an archive of firmware in free access. I recommend using an alternative firmware from blissz for D3
