BITMAIN SCAM

recently i stupidly upgraded firmware of their antminers. Due to noise i had to turn down fan speed otherwise neighbors throwing fits daily basis. recently i upgraded firmware and had increased to default settings freq only to see what new improvements they done, bad mistake, i tried looking for original firmware by the time i got to the miners, pretty much some totally screwed to death and some if lucky i have a hashing but missing or burnt boards. cant find the original on their site have they got rid of it to scam us to buy more devices before we roi if ever on our older units, noticed few things gone esp the fan speed.

think this is a bitmain scam to earn more $$$ off us so we buy more miners....! and units are out of warranty period and have to buy a newer risk a 2nd hand units off private sector.
