On that topic...

I'm waiting on a "small" order of 30 S9k miners... 
Got'en for very cheap

Any suggestions on an alternative firmware?
Any way to bypass the signature lock (if they come with the latest-locked Bitmain firmware installed)?
Ideally I'd like to have them pop up in my current HIVE account (HIVE has a "client" firmware for that, but I first have to bypass the sig-lock)

Thanks
