I was having a problem with my AntMiner S3+ that had become unresponsive and inaccessible after I ticked a wrong check box while trying to get fancy with the network config. I was trying to connect the miner via WiFi, and also use it as an access point for my Raspberry Pi that's running a Gridseed, and I bridged the wrong two interfaces. I've seen a lot of posts in this thread with suggestions on how to fix it, but they are all either incorrect, incomplete, or unclear.
First off, no amount of fiddling with the reset button did anything at all, and I tried for many hours. Pressing the button once does nothing, holding it down for >10sec makes it restart as does double-clicking it, holding the button and then starting it up will just cause it not to boot. Someone said to start it, wait 3 minutes, hold the button for 15 seconds, do that again, and power cycle it... which didn't work, either.
I was able to fix it by connecting to the serial debugging port on the interface board with a USB to serial adapter, and editing the /etc/config/networking file with the correct settings and rebooting. The post that gave me the hint about the serial port was a little ambiguous on the TX/RX pinouts, so I wanted to post a pic that should be self-explanatory. I'm using a Parallax 'Propeller Plug' that I got for about $10 when I built a Propeller on a breadboard. The driver makes it show up as a regular COM port, and I used PuTTY under Windows to connect to it. The pin headers are just sitting in there, the worst that might happen with a loose connection is some corrupt characters in the terminal. The reset pin is not needed.
Hope it helps!

I have the same problem here, I hope that BITMAIN offer a solution to this problem, in the meantime I try your solution.

Thats exactly what happened to me. Very frustrating.
This is because the latest S3 firmware is even more broken than the previous broken firmware it was supposed to fix. Time & time again Bitmain release completely untested firmware, choosing to use their customers as guinea pigs instead of doing the testing themselves.
Vent your frustration out on the S3 thread - as I have done

only this message 
what can i do, maybe u can help me??
what can i do, maybe u can help me??
Sorry, I'm not sure what to do about that one. My only problem was that I needed to log in and change the IP address, using the 'ifconfig' command. It's saying it can't mount the root partition, which basically means it can't even see the operating system files in order for it to boot.
I'm not really familiar with OpenWRT, but the miner's software seems to be largely based on it, if you can't find help here, you might try a forum for that.

I use the 20141024 firmware. I installed the latest one (20141126) and it ended up slowing down GH/s after about an hour (tried for over 24-hours but had at least 10 reboots and 1 re-image in there). Gave up and re-imaged with the 10/24 firmware and I'm back to where I was and stable.

I just updated all my s3 with the latest aug 2014 firware, and now the performance sucks. What are most s3 users doing to improve performance.

Any new info on the mythical S5 yet ?

Hello,
my miner do not start because i try to update the firmware and the power was gone..
so now the miner start but only the red flash is flashing and i can not connect via LAN.
i try the debug ( thants for the pic, you are the only man in the internet that show this.. )
but i have problems whit my debug
My Miner: Antminer S3
my result:
Start only Miner:

All the current set of miners whatever company its is almost outdated.
We need new 15nm or near 15nm technology now to fire up the btc now.
Hope BitMain learned many lessons from their S2, S3, S4, other and will come with an old style S1 type product again.
With 17nm or 15 nm and a proper pricing will make home miner back into the race.
Or, only cloud miner from now onwards, world is changing.

The 'sale' is actually a very fair price to medium-level and larger buyers.
You can use 1 coupon ($400) per 16-pack. That makes the final price (shipping included) $12,688 - or $397/TH. Thats cheaper than 16 units purchased individually with coupons, particularly considering that the price includes about $2000 discount on shipping costs you would otherwise pay. Thats about 1BTC/TH WITH PSUs DELIVERED.
in contrast, the SP20 deal works out to around $415/TH and does not include power supplies (another $40-70/TH) and do not rack-mount.
noone includes the custom fees in their price - every customer pays different fees depending on country and personal/business use.
IMO, would love to see a 4-pack/$3400 (shipping included) option for the smaller miners.

A much better deal is 15x SP20
Cyber Monday Special Price: SP20 Mini Farm Batch 1 $10,425.00 +free shipping.
$695 per miner.
You can easily underclock/undervolt SP20 to 0.55w/GH to extend the lifespan and you are still 1200GH/s miner.
You will not be able to do this with Antminer S4, S3 or even C1
SP20 be more expensive, but much longer lifetime for mining.
The most important. If you buy the SP20, then get a new miner, not "2 months tested" miner.
Also you know they aren't going to build an SP20 mining farm, like bitmain already did with their S2's, to compete with their retails sales to us. How long till we see an S4 bitmain farm. Not a "testing farm" that is.

Tell the UK custms the 15 sp20 will only roi 9 btc so the value is really only $3300 and tax on that.

Perhaps Dogie can clarify these "specials" for us.

BEFORE SHIPPING:
16 individual units - 34.081 BTC ( 12800 USD )
Brack Friday Bunduru - 33.834 BTC ( 12688 USD )
$122 somehow works out to 30% of $12,800?
?
SHIPPING INCLUDED
16 individual units - 40.234 BTC ( 15109.95 USD )
Brack Friday Bunduru - 33.834 BTC ( 12688 USD )
so you do end up saving significant shipping costs..... if you live on the opposite side of the world. Not so much if you live in China.
Being forced to purchase 16 units, just to save on shipping costs, is not a "sale" IMHO.
Especially when shipping was included on everything, up until not so long ago.
Buyer beware.

Try importing 16 units with a declared value of $12,000 into the UK
The "HM revenue & customs" will declare you a "Commercial Buyer" and require a vat number before allowing delivery.
Then you will need to produce "accounts" to show what you have done with them.
Edit:- even one unit of the S4 will attract a tax challenge.

>30% off Black Friday Deals
Special Sales for ANTMINER S4, 0.409USD/GH/s, FREE International Shipping. Shipping on Dec. 2nd
Also that coupons are not applicable.
And finally that without coupons being accepted, that the price per unit works out to being $818. Which is $18 MORE than buying a single unit with a coupon.
Shipping appears to be included. For a change.
Customs fees I highly doubt are included. As usual.
Unless you are in the market to buy 16 units, this is not an actual sale. And even then you save very very very little. Basically cheaper shipping.
How about actually giving 30% off the price of a single S4, and still allow the coupons..... so it is not completely and utterly useless to everyone, as this so-called "sale" currently is.

Might want to mention that you are forced to buy SIXTEEN units of S4.
Also that coupons are not applicable.

My bad.
It is more retarded than that.
You CAN use coupons. 1 coupon per 16 units.
Again, allow us to buy individually at the 30% discount..... because this is not a sale, it is a wholesale liquidation at best.
Failing that (as I expect you will) you should at least follow your own policy that you have force fed down my throat for so long..... ONE COUPON PER UNIT, AS PER BITMAIN POLICY.
EDIT* otherwise, please announce that S4 are "ON SALE" for $18 more than usual price, BUT the catch is you have to buy 16 units to pay more for them.
I think that your math is incorrect.
Regular price: $1200-$400 (coupon)+$160 shipping=$960/unit delivered to US
sale: $818/unit-$25 ($400/16 since you can use one coupon)=$793/unit delivered to US
savings per unit=167/960=~17%
however, you need to get 16 units, which is a deal breaker for me, but probably OK for some large scale miners.
November 29, 2014, 02:40:32 PM
BITMAIN - Please do not lie any more
This is only free shipping , if you buy at one time 16 Antminer S4
You can use one 400 USD coupon per purchase 16 Antminer S4. One Antminer S4 price is 793 USD . It is not >30% off. This is only free shipping.
Hold on champ.
Shipping is NOT free.
That is another one of their lies
After you work out the price difference, shipping is CHEAPER. It would be incorrect to describe it as free.
