Could anyone urgently help please.

I have D3's plugged in, I've updated their Firmware to the latest on the Bitmain website and since then I keep getting this issue.
The chip statuses go to XXXXXX and hash 0.

I've tried reflashing it with the firmware again and doing a power down and on.
I appreciate any help, thanks!
