Hi Guys!
I've received some of Antminer S9 few days ago. I had same problem as you with blank hardware and bmminer. The solution for me is resetting to factory and giving new configurations. Some of them worked with new configurations only.
Method 1:
go to web interface of the miner you have trouble with:
1. System>Upgrade>Perform Reset (or just press reset on hardware).
2. Give new pool configuration.
Method 2:
1. Just give new pool configurations (I mean another worker id).
The Bitmain Support team couldn't help me a lot. The only one solution given by support is upgrading firmware. They couldn't even send me firmware to upgrade as far as I can't open the link to download it.
