I have ordered a 3 new motherboards for my S9 antminers and they worked just fine for a while, but around a day ago they have started to mine to a different address than mine. The address is: 3CJgXokLQrRCQcEoftS7MbPDSXhXpX6P55.

And it my miner status page looks like this: https://imgur.com/a/QyNOIjf.

I did a google search of course,and I've found that this supposed to be some kind special software and it includes a developer fee as well. I would accept the dev fee if it was reasonable even if i have never wanted to use this firmware but it goes on my other miner for over 12 hours.

I'd like to get rid of it as soon as possible. I don't want to use other people work for free,and i would like to not mine for another individual either.
Reinstalling a genuine firmware only seems to solve the problem temporarily.

Any help would be appreciated.
