As an incentive, I will send my first 24h earnings to the person that helps me fix this without replacing the board (if thats allowed by the mods).
Over the course of 3 years, I helped countless people troubleshoot and fix their mining gears, some folks here have been around years before me, most are helping out for free, there is absolutely no reason to incentivize the fine gentlemen here with money.
Just to confirm that you are not doing something wrong, please show me the files you used to flash the miner, and where did you download them from? also, what was the size of your Sdcard.
in order to troubleshoot your issue more accurately, we need to confirm that you did indeed Sdcard the control board correctly, sadly most people don't. , also, do you happen to have another miner or this is the only one you got?
Free advice, wipe and install an original Bitmain firmware from the Bitmain site, to ensure it's not a hack firmware that's the cause of your problems.
That's good advice, but his gear is nowhere to be found on the network, how do you expect him to install the firmware when the control board is defective?
