Hello guys!
So I was able to access my miners, and brought one faulty home to do what you have suggested.
I did the control board recovery as BitMaxz suggested,and was able to do it, i have both lights flashing and accessing the miner,but I dont see the usual miner interface, this comes up rather:

philipma1957 you were right, the miners are running the 2017 software, at least that's what they show.
On the other hand, ive tested this in the past two days, they do stop hashing at 7pm my local time. this is getting more and more interesting.
