So .You are not one.Yesterday I got broken ( not working BITMAIN 5 S ) Device is not working,dirty ,full of dust ,many scratches around screws from side panels.I hate this .I got contact with support and they apologized but after my questions about 90 days return policy I got only silence .No more friendly e-mails .nothig .I got piss of because   looks that some inviduals from BITMAIN stolen from me 1.76 BTC  .This is amount what I've paid for them .I do not recommended to buy from them .Company is ok ,but support service is not commuicative at all ..BTW  all phones what I got are no longer in service . How they can do this for people?? I can't believe

Prelude is correct Smit1237 any way to get this fixed known issue. My miner just tried to switch and died. Thanks

Actually it doesn't, unfortunately. If p= is set below whats being paid, it works, but if p= is set above the current price it doesn't switch to the second pool. It just stays stuck on nicehash, not getting any work, and not getting work from the second pool. It just idles.

Smit1237 thanks for the quick response it was driving me bats its just my S4 not switching out. Just went back to your firmware on it. Keep up the good work always appreciated. They should hire you at Bitmain to do the firmware.

Of course it solves that problem, if this firmware listed on nicehash...

Does Smits firmware fix the p=x.xxxx problem for switching pools from nicehash. Thanks in advance

No problem, enjoy! The firmware works very well, as do all of smit1237's firmwares. (he made this firmware for nicehash)

Thanks bud!

Just flash the firmware that you downloaded off of nicehash like you would any other firmware. You'll be running 4.9 with xnsub support once you flash it.

hey im trying to put 4.9 on my miner cant firgure it out. I know how to use putty. But im not sure how to flash this or if i just replace the files. https://www.nicehash.com/index.jsp?p=software#asic here is the link of what I'm trying to flash. I dont want to brick my s4 not sure how to reset it if i do yet. This one comes with stock fans. I would like to get input on anything you have related to this topic as well. Im all ears.

i agreed with that, this is bullshit with old bm1382 chips, they want to melt their chip stocks  

i will buy only S4+ upgrade kit with logical price if they did.. i dont buy this shit.

$1000 for 2.5th/sec?

Not really awesome.

From the S4+ description:

"
2. The PSU is designed by Bitmain. The headache around the S4 PSU will not happen again.
"

 

S4+ is coming out within a week.

Please try with other pools and see if Antpool connection was the cause or not.

Thank you!

I use Mining Rig Rentals and through there I mainly use Antpool unless a hip new coin comes out. I have 3 other S4's running the same way: MRR then to Antpool. Today I reformatted a new SD Card and installed it into the miner. After I put it in my details the same thing happened, got up to 2TH and then went back down to 0. MRR shows the miner online but is not hashing. As far as people asking about it being at work, its a small buissness with me and someone else. They know I do this and its part of my compensation since the owner doesn't even pay for power. I have 3 other S4's there running fine and set up the same exact way along with my 5 scrypt machines. But I do appreciate everyone's help. I will look into your suggestions, thanks again and I may be talking to you soon

@ jds1119,  

What pool are you using?  It could be the S4 or it could be the pool side or it could be the network restriction.

To test the PSU, please disconnect one of the four hashing PCBs from the PSU inside the S4.  If the unit remains powered on and continue to hash without any problems, then it could be the PSU being degraded and not able to produce enough power for 4 hashing PCB.

Can  you try hashing at KANO.IS to see if the miner stay connected and continue to hash? You can try BTCGUILD.COM as well as GHASH.IO. (Process of Elimination here... if the cause is on the pool end or not)


FYI:
We are hearing more an more Corporate Network being limiting Bitcoin Mining Activities via various way to restrict mining activities from the work place.

Applies to the non-working PSU showing these LED conditions

Try a new SD card with a new image flashed to it.

Sorry to say that one sounds like it is shot. If power stays connected and it reads zero sorry bud. Check if it is giving you x's on your monitor.

If someone could point me in the right direction I'd appreciate it. I have a 4 S4's. Today one of then just stopped hashing. It still runs but just not doing any work, says o ghs on the led. I restart it and it gets up close to the 2TH and then slowly(over 10 mins) goes to 0 again. I updated the firmware, same thing happened. I leave these at work so its a pain in the ass to go there 3 times on a Saturday to reset them. I just got back the final time and as soon as I get home it say zero again. Please and thanks. Is this a symptom that I need a new PSU or is there something wrong with the miner. Thanks again
