Just a thought if they don't come back online.  Since sfards is a mish mosh of several different mining companies.  One being most important gridseed.  I'm wondering if you have a spare flash card that you could put minera on it and try to operate this miner as a gridseed gridminer.  Just a shot in the dark but the gridseed towers I used to run had some odd proprietary software on it but I reflashed the sdcard to minera and it worked much better and the interface was so much cleaner.  These being gridseed chips I think you may get lucky at least I hope:).

This reminds me of the sfminer when they shut down the authorization servers which bricked all those miners.  I got mine fixed by a guy that worked for them at the time but if they aren't locked down by now they are useless miners.  No one was aware when we bought those that it was connecting to a central server nor did it disclose that during purchase.  Hell I didn't even know it was doing it till they killed it.  Sfards really dropped the ball on this whole deal:-/
