Hi, I am trying to help a friend who has a Seirra he bought but was never able to get working.  He bought one back in April with someone else and that guy flaked on him and he has no tech expertise and was basically stuck with it until he met me now.  I dont think a Seirra is even close to profitable now but I told him I would try to help him get it working anyways.

can anyone provide me with the latest firmware for the sierra?  I assume his has the original firmware since he has had it sitting around for almost a year.  I am able to get it working and hashing at 1.2TH/s but it constantly fails after 1 - 20 minutes with lots of USB errors.  Sometimes it will start and stop in less than a minute with USB errors and sometimes it will run for almost 20 minutes before the errors happen and cgminer crashes.   I am hoping new firmware will help.  Hashfast seems defunct or close to it, their setup.hashfast.com page doesnt work for me (i just get their website), I cant register for their site and they wont respond to support requests.

Thanks much.


Can you post the logs.
