I just had my miner die on me during Flashing a new firmware.  The issue was that my powersupply shut-off while the firmware flash was in progress.

After that, the RED light keeps flashing and the green Ethernet light flashes but I cannot go online through WEB or PUTTY anymore.

I tried resetting the unit but it won't work.

BITMAIN, do you SELL CONTROL BOARDS ONLY?

It would be nice to see a JTAG for bad firmware flash.

If all fails, I am willing to sell the HASHING BOARDS to someone with a good control board

OR

I am willing to buy a control board off someone with bad hashing boards.

LET ME KNOW IF SOMEONE IS INTERESTED!
