Topic: Hardware ver. x.x.x.x (Read 937 times)

I thought I had checked that....but I was thinking about it again after bitcoin hit 6K and decided to take another look.....I'm glad I did.

I changed out routers and I'm BACK BABY!!!!!!

Thanks for catching what I should have.....

Good to know for future reference, thanks!
I'd have to assume that during boot, anytime the miners cannot connect to a pool (in this case blocked by the router) it cannot perform its self-checks and that is why the boot process hangs giving that generic error message.

Ok, so I figured it out yesterday. I will post my findings here. Searches on Google bring up this issue on this forum, and several other sites. There is no resolution ever posted. I stumbled across a Russian forum that google stumbled through translating. That person was having the same issue with one of his miners. He moved it to another location for troubleshooting and it worked fine. The only thing that changed according to him was the network.

I do not know what network connection has to do with the BB board properly loading firmware and recognizing the connected hash boards but apparently it does.

I checked my router, I use an ASUS RT-AC68U, saw there was another firmware update, so I updated. After the update I was checking through some other settings. The log showed the "AiProtect" app was blocking malicious activity and sending alert emails. I received no emails of the sort, so that may be another issue. The ip addresses it was blocking were all for my miners. I turned off all settings for the AiProtect app built in to the ASUS router and BAM! green status lights and we're off to the races.

So switching off that protection as ASUS calls it and the hardware version on the miner no longer shows x.x.x.x and the cgminer field now has the version number and the miner status page shows all pools, board status, fan speeds, and temps, and the boards are hashing again.

So for those that run into this problem in the future:

Bitmain says the device "has lost its firmware" and tells you to reboot the device or reflash using a microSD. While this may be a viable solution for some, it may be easier to check network settings first, especially if more that one device is affected.

I know this post is a few months old, so I'm sorry for resurrecting it.

When I do a search only 2 threads come up, this one and another one. There is no resolution to either poster's problem

I am having the same issue with my miners

I WAS running an S5, 2 S7-LN's, and an S7

In late march/ early April they ALL stopped hashing.

The overview page shows "Hardware Version x.x.x.x"

The miner status page is completely blank no info there at all. Chip status, fan speed, pools, all blank.

Bitmain Support lists this exact issue on their website under item number 7 I believe and says that the miner has lost its firmware, reload and reboot.

Well its not that simple, and it didnt work

I have also replaced the BB board, and control board, and imaged several different microSD cards, all with no change in the miner at all. I have even booted them with the hash boards disconnected to try to eliminate them from the equation, with no luck either.

I have been communicating with bitmain support which has been helpful, but unproductive.

Has anyone else had this issue?

Was there ever any resolution?

I have already lost 3 months of mining, I would like to get this figured out if anyone can help me trouble shoot please.

Hi All,

Ok, this is strange....but bear with me. 

I all of a sudden, have both my miners (S-5's) just show....within 3 hours of each other, Hardware Ver. x.x.x.x on the main status page, and no cg miner version at all.

All mining has stopped.....obviously.

I did a search, and all I could really find was a suggestion to do a hard reset of the power, which didn't work.

So far, what I've tried (that's all failed):

Reboot
powering off and back on
hard reset back to default
reflash of firmware

Now....what is REALLY weird is that this affected one of the machines first, and after I accepted that this one is dead.....the other one did the exact same thing. 
How, do two machines that have been running all winter, one inside, one outside in the garage (both blown free of dust weekly), decide to show the same error and die within a few hours of each other?

I refuse to accept it's just bad luck.  There must be something going on.

The ONLY thing that has changed today is I installed a new router in the house. 
An Asus RT-AC3200.  How could a router kill two Antminer S-5's? 

I don't think it did...but troubleshooting 101.....what changed right before the incident?

Any help / guidance would be appreciated.

Thanks!
