Re: Antminer R4 - dead hash board? Shitty design, read before you send it back
7 out of 20 are defective with all kinds of issues. Just figured out that one has bad controller. Bitmain will send me a replacement.
I am trying to try your approach for issues like one hard board was shown. I wonder whether your approach works for bad ASICs? Thanks!

Sorry if my explanation is too complicated.
1) turn off the miner
2) unplug working board
3) start miner until it hashes.
4) if you are lucky, it will recover bad board
5) turn off miner
6) plug good board back
7) start miner until it hashes.
if you are lucky, you have both working boards
9) if you have bad luck, try it again. You can also try start "single-board-test" program via Putty several times.
NEVER stop or apply changes before miner start hashing. It killed my board, but I recovered it by previous steps.
