I've got two Bitaxe 201 boards. One of them is happily hashing away after applying esp-miner-factory-205-v2.1.3.bin directly to it over USB.

I was unable to connect via USB to the other one, so I updated the firmware to 2.1.3 (successfully) via the web interface. However, when I tried to update www.bin, it hung for about 10 minutes. After power cycling it, there's no display and I still cannot see it via USB.

Any ideas on how to get this working again?

Thanks!
