Hi guys, there are 2 "Logic Version" S9 Miner..... V2.30 & V.2.23 , there are any way to downgrade 2.30 to 2.23 ?
2.23 version seem it could be solved with bmminer-cgminer492 udpate-script
No, this probably means the hardware or xilinx bitstream is different and not easy to change. I'm not positive though, but I can tell you in a couple of days when my batch shows up if the control board is the same as old ones or if it is truly a hardware change.
