My Internet went down before i woke up this AM.

My S5s came back online when the internet came back up...but my S7 (batch 1) didn't. I can still see it when i check it thru my LAN. All the ASICs are there and have all 0's but there is no hashing. The fans are running too.

I rebooted. No change. I switched PSUs - still no change. I did a few reboots- no change. Then i reset it to factory settings- still no change. Finally, i called Bitmain in Denver. The tech guy used chrome remote desktop to look at my kernel log , miner status etc. Then he shh'd into my rig. He couldn't find a problem either.

So I will be contacting Bitmain to see what can be done.

Has anyone else had this problem?

I have this issue, go into Network>Diagnostic and then ping something. Go back after a minute and check if it is hashing.

Tried that already. The ping was successful but still no hashing.

Someone analyzed my kernel log today and replied with this:

"this looks like memory problem with your beagle bone black
change it with another BBB or find S5 BBB and reflash it for S7"

Bitmain said"

"i would suggest you to obtain micro SD card. and to mount s7 firmware from https://www.bitmaintech.com/support.htm?pid=00720151023101739550pOBiK5sO06A0

on sd card.

and then to place it in unit. maybe then unit will start working."

I will try that and let you guys know if it worked. I'm guessing more people will have this problem. If this fixes i, that would be nice.


I'd be very interested if this works for future units.  I have already sent the 9 hashcards and 3 controllers back to Bitmain.

It didn't work.

Now, I think the controller is bricked. All the LEDs on the front are now off. The blue and green lights inside the controller are solid ( ie: not blinking). I can't see it in my browser anymore. I can't reset it to default with the reset button.

So after 7 weeks and a few days of perfect functionality, my S7 is not working after an overnight internet outage of about 3 hrs.
 ( Note: there was an internet outage of about 30 mins a month ago. It didn't affect my S7 then. So, it seems if there's a longer internet outage, it messes up the controller or its memory.)

Bitmain Warranty has not responded to my ticket (#1384) since i reported that using the SD card did not work and the control board seems to be bricked. I also asked them if i could have approval to do an RMA and no response to that either.

Should I blindly send the controller ( with my invoice etc.) to Bitmain Warranty in Denver and hope they do something for me?

or

Do i have to wait for them to respond with some kind of RMA approval number like you you get from other companies (ex: Corsair, EVGA etc.)?
