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
Nope s9k are very very very special you are Locked in to bitmain firmware.
Hint disconnect the middle board on your troubled units. the psu part you can leave the data cable attached.
keep all of them very cold.
they run hot.
I had four of them they still work.
But 2 need the middle board not attached.
