Topic: Can't Log in to S3 Antminer (Read 2640 times)

Did you make a ticket with bitmain?

It's weekend now but tomorrow if you do make a ticket they should get it.

please I paid a lot for the s3+ so how do I just reinstall the firmware and I'm terribly disabled and crippled and have no energy?  I don't get any echo from the serial-USB connection when I type into the putty window or the cursor doesn't type.  the controller board lights up red though on power on.

This is something there is not the greatest documentation of on the board.  There is some but I highly suggest putting in a ticket, they might even help via remote to your pc.

Anyways put in a ticket over here or bitmain and ask for help: https://bitmain.zendesk.com/hc/en-us

I have everything configured with 115200, 8,1,n,xon/xoff and the adafruit cable connected to the male connector pins which were soldered to the board.  Do I change the settings somehow? 
I am getting no echo when I paperclip jump the TX RX. 

Opening multiple tickets really will not help.  One ticket is better as it shows all the work in it.  Depending on you location bitmain does have a phone number for some countries.

But if your are honestly having that much trouble you might ask them about buying controller board.   

well I got the one s3+ mining by flashing the cgminer at 441 GH/s!  but I still can't serial connect to the other s3+.  I tried paperclip jumping from TX-RX on the serial-USB raspberry cable but don't get any echo.  with some combination of connection of cables to the debug holes I can type but can't reset the controller though it has a red light.  maybe it's not fixable, it was mining fine until I powered off during firmware update. 

I've opened 2 bitmain tickets and they tell me to serial connect with an adafruit cable.  I don't know if my cable is an actual adafruit or a copy.  so I'm not sure why I don't get echo when I type into putty or the window doesn't allow me to type.  when I connect RX and TX without ground to the s3+ I get a stream of nonsense text

Is this router going to work?  it does have a bridge mode.  I'm 4.0 in the US in mathematics/physics

Quality of Service (QoS) support

The ZyXEL AMG1312-T10B comes equipped with essential ATM QoS features. Service providers can freely design their QoS policies and prioritize mission-critical services such as IPTV and VoIP based on their service plans. This increases network efficiency and productivity that enable service providers to bring real multi-play services to the daily life of residential users.

Easy customization with ROM-D function

Service Providers need to have a quick, easy way to customize and manage different firmware versions before networking devices are distributed to fulfill specific requirements from different customers. The ZyXEL AMG1312-T10B features ROM-D to provide the flexibility for service providers to change default configuration settings easily through just uploading of a new customized configuration file.

Always-online, always-compatible alternative 3G connection

The ZyXEL AMG1312-T10B features optional 3G connectivity as a failover (or alternative) connection to 3G mobile broadband networks in case of DSL outage; with which Internet traffics will be temporarily routed through the user’s 3G dongle plugged into the USB port.

It is also efficient to have instant Internet access in remote offices, activities outside of the offices or for occasions where DSL service is temporarily unavailable. The AMG1312-T10B works with most 3G dongles from mobile broadband SPs thanks to the latest 3G compatibility list and frequently revised patch file on the global Web site. Users can simply check and download the patch file to enable mobile broadband services immediately without upgrading the entire firmware of the gateway.

There is not restricted like it once was only letting you in beginner thread.  Only thing is you have to wait on time between post's with account (and cant have avatars yet, and sig is less).   But as far as posting it is just really waiting, and no way to skip this.

Changing network settings can be dangerous if you make a mistake.  If you did make it go to DHCP log into your router and see connected devices and try to find it in there by connecting to those IP's.

I like antpool better myself.  It has multiple US servers so works out well for my miners personally. It is a good pool and one I really like to use.  I can use PPLNS (0% Fee), or PPS (2.5% Fee).   So nice to have option.

But again you need to sign up on whatever pool you use to get your own username and worker.  Using the previous owners worker name will NOT mine for you it mines for other person.

With two I would look into a router that can connect to the wireless as a client and allow you to plug ethernet cords from the miners to it.

can someone please give me unrestricted posting?  I need to do this s3 serial-usb fix today and I'm bedridden and exhausted and foggy.  my lungs are really damaged and the doctors can't do anything

I just switched the WAN and WWAN to DHCP and now I can't find the miner??

I entered on the GUI, stratum+tcp://stratum.f2pool.com , professor21.adsfdg21 is this correct?
from a WIFI connection only it is showing 0.0 hash rate but 172 accepted on f2pool.  but you need to add an antenna or drill one to use WIFI and the connection could be bad?
the coins.co advised me to go to cex.io for some reason, I don't know if it's a better wallet.


so the antpool is the best and the solo pool?
I could connect via LAN but that's going to burn out my laptop

You need to sign up to the pools and get your own worker name.  If your using the one it came with chances are it's mining the old owner.  Personally I'm not a huge GHASH fan but if that is the one your wanting to mine on you need to sign up on their site.   

Worker passwords do not matter on most pools they can be random and have no effect.  (Some do use them for custom configuration)

sorry I'm crippled from lung problems and have no energy and lost my hearing.  I had the pools configured like this but I couldn't add workers on f2pool or cex.io
So I was getting no mining on the graphs or activity, just a bit from faucets.

ghash.io is showing this and I wrote in uk1.ghah.io:3333 as the pool and up100134865.xxx on my s3 config screen

Stratum Servers: uk1.ghash.io:3333 or us1.ghash.io:3333. Please use -o stratum+tcp://uk1.ghash.io:3333 in your command line. You should name your workers up100134865. (e.g. up100134865.worker1). Workers are added automatically, you can use any/empty password. The minimum stratum difficulty is 16. Support: [email protected]

is the bitmain pool the best, I noticed this pool has 0% fees

I'm trying f2 pool but does it need a country prefix, how do I enter the command line and can it mine from WIFI from WAN or WWAN connection or do I need a router with minimum speed like 10mb/s to maximize speed?

I believe it is the debug box at top of this pic - https://farm6.staticflickr.com/5551/14690957071_8b5e266d32_o.jpg

Here is a topic that should also be helpful - https://bitcointalksearch.org/topic/m.9844329

Best of luck.

well bitmain gave me a great response and told me now to reprogram and reinstall the firmware with a serial-USB connection and TTFP like solarwinds.  But how do I connect the 4pin connector to the controller board, do I unscrew the board? 

I'm going to do the repair tomorrow with the raspberry connector.  I was on f2 pool and cex.io and coins.co but couldn't add workers.  I need to get a router with bridge capability?  the s3s can't connect through wifi with WAN/WWAN?

Is there a way other than Dogie's on this site to do the factory reset?  I turned on the machine waited a while then pressed the reset button for 15 seconds waited a few minutes pressed it again and then powered off and powered back on.

I'm not sure how to connect this raspberry serial connector.  Do I power it off first and then power it on and enter the commands from ttfp solarwinds?

here's a picture of the controller board, do I plug in the serial into the connector below the blue square?

On the config page as long as you saved and applied then even if the that pool information is wrong it still should show up on the miner status page but they would be dead ...the status is not showing anything? The reset button would have defaulted back to Bitmains pool information also...not sure what is going on.

Bitmain has their own pool antpool. - https://www.antpool.com/home.htm   It's easy to sign up to and help on connecting here is help - https://www.antpool.com/support.htm

If you have trouble just post a screenshot of your pool configuration and we can try to help you out on it. You will need to sign up first and register a worker name.


Sorry to hear about all your problems.  On the one that was turned off during update sadly it sounds like it is bricked.  So it will either need the serial to usb cable to try fixing (not guaranteed to fix but does on some cases).  Other option is contact Bitmain via ticket - https://bitmain.zendesk.com/hc/en-us .  Tell them in ticket about turning off during update and chances are it will be a RMA and they can tell you cost aswell.  

how do I get the worker configured on cex.io or f2pool or another good pool?  I show internet activity but no hashing on the control panel.  they also have this activate currency feature which I pressed on cex.io but how do you reverse that?

is there anyway to fix this by connecting the s3 to a router??


this is such a terrible disastrous loss for me and I'm in the hospital and need to pay for hospital bills.  I've worked 48 hours and can't even get the units mining
there's a red light on the controller board that's constant and the red light on the outside of the box is also flashing. 

what do I need to do to the 3 pin connector at a 90 degree angle? and what are the putty commands?
"putty using 115200,8,n,1,xon-xoff,
connected tx to rx and made sure it echoed"

On the serial to usb it's a adapter you would need to order online.  Most likely you will not have one.  As far where it goes there is a spot on the S3 controller board all 3 pins fit in.  If you have to ship it in to bitmain yes it is easy to get the controller off.

Can you take a screenshot of your pool config page? Host the screenshot online there are lots of services to do this.  It would be easier to troubleshoot this page this way.
