Any suggestions for a board with resistance to firmware updates? It's back a few notches - several releases behind but it just returns ' Invalid Firmware ' every time with any of the official Bitmain firmware updates. I was wondering if anyone else has come across a similar issue with the R4. Thanks in advance for any thoughts.

I had the same issue with mine. Im just running the old firmware where you can pick your frequency (550-650).

Strange. Do you know what batch is yours?

If you have the 2016 firmware, You should be able to upgrade to 2017:

Antminer-R4-all-201704280718-autofreq-user-Update2UBI-NF.tar.gz first.

If you have the 2017 firmware, then, and only then, you can upgrade to 2018:

Antminer-R4-xilinx-201811121649-autofreq-user-UBI-NF.tar.gz second.
