Hi Guys
I've have an Antminer S4 running happily since early November without any real issues.
But yesterday, it didn't want to bootup. I think I've diagnose the problem as a faulty SD card. I've bought a new SD card but I don't have a backup (I had made one, but I've lost it)
How would I go about reloading the firmware on the SD card? I searched but can't seem to find a guide. Or where online can I find image of the SD card?
I stay in South Africa and have sluggish internet so to minimize down time I would prefer not to download an entire 4GB image clone.
You can also check out https://bitmain.zendesk.com/hc/en-us there are images for every miner and instructions how to do it...

Why do you need to reload the firmware of the new SD?

anyone have a guide on pointing a antminer to a QT wallet for solomining? There are several other SHA-256 coins i would like to try to solomine direct through wallet, but I can never connect to them. Only my old USB miners connect to wallets.

Why do you need to reload the firmware of the new SD? I bought a cpl used and one would not boot, after checking all cables etc. I slide the SD card out put it back in and it booted. My theory the pins on the SD card reader are silver and the SD card contacts are gold. Oxidation due to dissimilar materials. All be it I did not observe any visible oxidation thats my theory, or maybe the contacts were just not seated properly due to shipping knocking them loose? Who knows but it worked

yup I got the email from zoomhash 499$ new hard to beat that well the $100 shipping was a turn off, i got a cpl used from gawminers a cpl weeks back for $475 shipping included. but definately a decent sale at zoomhash but they need to rethink that offer a bit $459 used versus $499 new well dont see many people buying the used ones at that rate haha BTW these have been selling on ebay all day long for $700+ I am so tempted to buy a bunch to resell them, people on ebay need to learn how to use a search engine

Hi,
I will share my experience with my order, sorry if you are tired of reading same things.....but I need to share my feelings, hope that someone will be able to help me one way or other.
I bought 32 units on black friday, only after one week mining, 6 PSU gone, and one PSU fan.
I had to wait 20+ days to get the replacement PSU, didn`t send the fan ( I replaced myself and is not the fan so they should send another PSU).....and no compensation for all inconvenients coming from almost waisted miners they sent to us.
I said during that RMA that I was afraid cause 7 PSU broken on first week is almost 21,8% of mining power off, a whole month.
As is obvious we had to pay shipping costs and clearance for the PSU, again.
In the last week, 12 PSU gone away, one per day.....only some days before Bitmain warranty expires......
So, from 32 miners: 19 PSU failed....around ~30% of the order in the first trhree months.....wow. Sadly four miners have got issues with: • Faulty chips, I made my own troubleshooting changing cables to isolate the problem, but Bitmain did not send anything...... • Ethernet connection. • Fans in no working conditions. • Some of the cables, arrived broken, burnt, and full of dust and other rubbish. What kind of new is that? I have a video of that. • One ChipBoard has its Screwed 12V+ and GND- connectors lost, cause the first time we had to screw off the cables they just got broken, just like if I had used a Katana and we were cartoon. • One miner only hashes if the initial Bitmain pool data is on the configuration, cause when we change it, the miner gets lazy, no hashing. I really enjoyed this order, my first order to Bitmain.....till now they did not solve any of my issues quickly....Mining Asic manufacturers.....I was dreaming that someone could make the difference, not only on the technology, they should take care of their Customer department and the relationships they handle. Customer is the same as Future, why to renounce such way.
Best Regards.

All companies have some issue, I am a HUGE Bitmain fan though, I have over 80 S3 a couple S2 and now 16 S4s running. Never an issue with the S3's, couple small things with S2, but the S4's I am hoping is just the SD card reseat - they emailed me to try that out.
Other Bitcoin tech companies have a much more checkered past, with pre-sales, and over pricing to the extent you can't ROI on the gear. Keep going Bitmain, and I'll keep buying.
Bitmain is guilty of pre-sales and some would argue their gear is overpriced. Like the $425,000 "sale" for 1 PH/s of hosted power, plus electricity. M If u aint got nottin nice to say, Then u have no business being on this thread. This is for sales & tech support not for u i ant got ones to trash something u don't have.... Go to the speculations section for crap talk & rumour spreading..

Amended: Quackers, did some reading ... AFTER posting questions but still some input would be nice.
What is the CFM capacity of the stock fans? found this one, I think... 238.09 but then it further states 27.6W Power consumption, 4300 RPM, and 60 DB-A (my S4 at stock is running at 3600 RPM and the rear howlers are 74 DB-A so my Android tells me) I don't want to imagine 4300 ... there has to be some relief, no?
Any recommendations of replacement fans?
Considering Delta 1212SHE-F00 ... guess only as possible front replacement... (know this one, works on S5 very nice, 51 DB-A)
Read through Digi-key catalog for Delta Fans... This seems to come closest to the stock one... Delta Electronics AFB1212GHE-CF00 (scary 5200 rpm), but wait, there is more ;-) this one at 1ST PC CORP. Delta QFR1212GHE-PWM (6000 rpm, 210 CFM and wait for it ... 64 DB-A at a 'cough' 39 bucks).
Does anybody know any of these fans? PWM working of the QFR? (AFB 4 pin Molex power and RPM sensor TAC output through its 3 Pin) I need to modify something here? (I really suck at modding)
thank you

Hi Everyone, I think my S4 PSU died this morning, I have only had the machine 3 months or so and i think the psu is dead, could anybody help me figure out if it is and how i go about replacing the PSU I woke up this morning to find one breaker on my board had tripped, I checked the S4 and the PSU doesnt show any signs of life at all, I have checked the fuse and thats ok, but the psu does not boot at all, is there anything i can do to fault find. I know i had one of the newer PSUs that didnt have the issue the first batch did, and the S4 has been running flawlessly since i purchased it, just a bit depressing to see one of my best machines go down Any help would be really appreciated.

if you have a dead PSU, please PM this account with your Bitmaintech.com OrderID and what happened to the PSU, please take some photos with your username on it.
Questions regarding using a different PSU while the original PSU is dead. Yes as long as it is a strong enough PSU, you can do so with your own risk.
S4 is designed specific with this PSU, so if you use any other PSU, please consider how much watt each line would pull and power cord gauge) If you modify PSU to fit with the connectors on S4, it could be hazardous to splice the wire without a proper process and it may create a fire hazard or electrical shock hazard.
i think my PSU dead then file ticket since 2015-02-25 03:46:16 (ID:#1179) the support not answer me since 2015-02-25 07:12:45 then found this post , PM BitmainWarranty and not response , then post http://forum.bitmain.com/bbs/topics/1374 , and not response again , back to PM BitmainWarranty still not response , then post here and what can i do next? thank you

My 2-cents is to get an IBM 2kw PSU (208-240v only) and breakout board to replace it. http://www.gekkoscience.com/products/IBM2K_board.html is a good source for the breakouts and PSU's or check eBay for the PSU's. Together they should run around $75-80 total+ shipping. I got 4 of the beasts for when my S4's croak...

Anyone know if this would work for an S2 as well? Certainly though is hefty overkill for the S2 as they 'only' pull a hair over 1kw. If you have >208v for feed then the HP 1200w CS (Common Slot) supplies would be a better match. Just have to do some soldering with those tp attach the PCIe power leads as breakout boards are not easy to find.
