So just as a recap, the steps you need to take if your SD card gets corrupted and a simple reset on the front control panel won't resolve it:
1) Power off your Antminer
2) Take out the control board. On the back of where the ethernet cable plugs into you will see a MicroSD card, remove it.
3) Take MicroSD card out and put it in a SD card adapter to insert into a laptop or 5-in-1 card reader
4) Download The bitmain.img from https://dl.dropboxusercontent.com/u/16075357/bitmain.img.zip (Courtesy of l1l1l1l1) as well as Win32DiskImager-0.
5) Use Win32DiskImager-0.exe to mount SD cards as an "image-able" device. SD cards do not inherently accept images with default Imager software.
6) Image the Bitmain.img to image to your SD card.
7) Once done, plug it into your miner, make sure your ribbon cable is plugged into the main board nice and snug, and fire it up!
You should be done short of re-configuring your miner. Remember that this resets it back to 192.168.1.99. The image used does not work for me by default, so I had to "reset to default" with the front bottom-left button and reconfigure my settings.
If anyone wants a video demo of this I would be happy to make one if someone thinks it would help. Cheers!

If you see only 60Mb use SDFormatter.
It will help.
It will help.
hmm.. i copied the SD files and formatted the card, it still says only 66.5Mb
when i try to boot up i do see the blue BBB leds flashing PLus a solid red led on the BBB ive never seen on any KnC rigs
but no matter what i try i cant access the GUI at all.
when i try to boot without the SD card in, i get a password confirmation box that wont accept root/root or root/admin.
All it does is reverts to asking for PW conf again & again & again. If i put the SD card back in i dont get that PW conf box and only 404 not found error
i was going to put your image onto the disc until i saw it only has 66.5MB.... im assuming now the SD card is fkd

You have to write the image to the SD card with Windisk32 (aka windiskimager).
Cheers
thx. but the image is 1.8Gb and the SD card while having 2Gb printed on it, IS ONLY 66.5Mb...
Thx for the pics u posted l1l1l1l1, i saw what i wanted to there but im now pretty certain this SD card is fkd
I think you should give the re-image as suggested a try. SD card is NOT only 66.5mb, as someone else has mentioned the device gets partitioned up and what you are seeing is one of the partitions, i see the same thing too in windows for some reason, it only shows me the 60-something partition. If your on windows look at the disk manager on your laptop with the SD card in to see what im referring to, you will see all of the partitions . I purchased a brand new card which was initially showing 16gb free. After flashing it as per 111's instructions i can see it got partitioned up and windows will only show you the 66.5 size when viewing it after. Please give it a try.

corrupt SD cards.
twice now, i've gotten corruption on the SD card on one machine or another. If there's a power cut, i cross my fingers and hope for the best. chances are, at least one machine will need it's SD card removed and re-imaged. Big thanks to the guy who posted a link in this thread to a copy of his SD card. Although Bitmaintech has now posted updates to the firmware, they are in the format needed to update via the web gui - not directly image the SD card.
this problem is particularly concerning as there is no "shutdown" option in the GUI or button on the case. just the power switch. So each time you shut it off, you have a 50/50 change of buggering the software.... yikes.

If anyone has a step-by-step on how to image the SD card using Win32 Disk Imager and the downloadable "initramfs.bin.SD-20140410.tar" from Bitmaintech's new support page, it would be VERY helpful. I'm using an image file someone posted much earlier in this thread, but it's the old firmware version.
You're welcome (from earlier) and I've updated the file to be an image of the latest firmware, IP of 192.168.1.99
https://dl.dropboxusercontent.com/u/16075357/bitmain.img.zip
Link is the same, so using the other posted link will grab the new firmware. It has my mining info in it, so be a gent and let it mine for a bit! lol
Sorry, but newb question, i have gone out and purchased a class 10 spare, but i havent the slightest clue on how to image that SD card and have it ready in case the one from Bitmain croaks. Can anyone give me the procedure ? 111 Thanks so much for making a new image !
You'll want to download win32diskimager. Unzip the image file, then select it in diskimager, then choose your SD card (you'll want to get a micro SD usb card reader) then click "write device" it then writes the whole image to the microsd card and there ya go, drop it back in the S2
I imaged this with your image, but I can't see it grabbing an IP on my network now... any ideas?
It is assigned a static ip of 192.168.1.99. It does not grab an IP via DHCP, so you won't see it in your router's DHCP table until you successfully connect to the S2's web gui and change it to DHCP. Apologies if this sounds overly basic, but just to be clear, you can't access 192.168.1.99 unless the rest of your LAN is in the 192.168.1.x subnet. Is that the case?

The SD card is not 66.5Mb. The first PARTITION is 66.5mb. You need to wipe out all 3 partitions, freeing up all 2gb of space, THEN write the image.
Quite honestly, I did it with a Mac using Disk Utility. I'm sure the process is quite similar using the volume manger of Windows. But if you just reference the drive letter of the first partition, you will only see 66.5mb

Antminer S2 turned up today, it was in horrible condition, cards loose everywhere, thermal paste everywhere, pci slots all bent to shit, after an hour and a half or so of fiddling (2 screws were stripped and needed to be drilled out) i managed to get it back together, then i had a problem with the screen, played around some more and got that working.
PROBLEM!
Its turning on and mining (all cards are flashing, hash rate on screen etc) but it will not allow me to access the settings and displays a "404 not found" error and on top of that it will not login via ssh with putty and tells me that the password i am using username: root password: root is not working, so i cannot even change pools.
Bitmain shipped me a unit that is basically mining for them!
Can someone please help?

For whatever reason it's either got a different user/pass or different IP or something. A sure way to get it to the right IP/user/pass would be to image the microSD card with my image.
Format the card and image it, try to boot, if it won't boot take a few asic cards out so you can read teh BBB and eject the sd card while the unit is on, then put it back in, you'll see the ethernet lights cycle, I've had that make mine turn on before.
In other news, I did have a bad BBB that wouldn't write to the SD card. I replaced it with a factory BBB, that's what my machine is using now
Ahhhh, now THAT was some f'ing good advice! thanks mate - you're the best. followed these steps and got each one working with 8 boards. Sweated like a blackjack player holding 17 for a while, wondering if i should stick with what works or risk it and try adding the other two boards.
I chose to try something new - i ejected the SD card while it was running. Left it like this for about 5 minutes. it kept mining! i then powered it off, added the two boards, popped the card back in and turned it on. magically, it booted it up just fine!
So, until i figure out something better, this is my step-by-step to deal with the corrupt SD card problem:
shut off
remove 2 asic boards and sd card
reimage sd card via laptop
boot up with 2 cards missing, pop card in and out until it boots (you can tell when the blue lights on the BBB card near the ethernet card light up)
when it's running, pop out SD card, power off, then add 2 boards, pop card back in and hope for the best.
From what I can tell, the SD card is only used to load up the OS, once it's there it runs from memory. so removing the microSD card before powering off is definitely a way to keep it from getting corrupted (again and again and again)
i emailed bitmain but his advice was to reseat everything and try again...
i have done this a dozen times.
is the BBB supposed to have a solid red led lit on it?
404 not found even after hard reset means something is wrong for sure
startin the rig without the sd card makes it spin loud continuously and the lcd screen never 'arrives' despite being lit.
20 secs after inserting the sd card it settles to 'idle' and lcd displays;
antminer s2
192.168.1.99
0GH/s
Max 0C
cannot access gui, cannot access via Putty...
root root
root admin do nothing
if im going to reflash the sdcard do i just swap 1l1l1l1l1l1s 1.83Gb bitmain Disc Image File with the u-boot 370Kb Disc Image File??
why are they so different in size?
urgh... 9 hrs so far !!

The disk image I made is of the entire microSD card, thus the entire 2GB card, including free space. You'll want to download win32diskimager and flash the entire image to the microSD card.

does anyone have a pic of their control board?

Pics of the controller were posted earlier by me, you'll have to dig in my post history to see 'em. If the SD card is corrupt the unit won't boot, and you won't see the bright blue LEDs on the BeagleBone Black card.
shame you're not closer i could use it as a mouth/finger stopper.
anyone have any idea why the 2Gb SDcard has only 66.5Mb of space on it?
anyone who isnt a 'seriousclown'?

Yes. $50 and i'll tell you.
no, i'm not that douchy. The SD get partitioned into 3 pieces. boot, boot backup and unused. first two are about 70mb. third is whatever is left on the card.
i've used 2gb, 8gb and 32gb successfully.

u want 50USD per hour to pass on help you received for free from our very community....
Hey sucker, pay up or forget mining if its too hard for you.
if there is a hardware/SD issue does that mean mining is too hard??
get back under ur bridge if using ur brain for anything other than being a douche is too hard for you.
Meanwhile, you can use your S2 as a door stopper .....
Guys, we're the Bitmain community here on the forums, not the BFL, KNC or HashLast. Let's keep it civil, let's avoid name calling and negativity. I'm here trying to catch up and getting ready to respond and I see negative comments, it's distracting and just puts a bummer on things. Keep it cool? Answering questions next :-)
After about 10 mins the whole unit powered off and has been unresponsive ever since.
I've unplugged all outputs from the PSU and it's still not coming back up, so it looks to be the PSU.
Any ideas on what to try to resurrect? I have multiple CX750M PSU's but nothing big enough to replace the 1000W Enermax.
Cheers
I followed some advice earlier in the thread and removed one blade, it's now been mining for a couple of hours so far.
These batch 2 units are a lot quieter than batch 1, with larger effective fan diameters and case holes, they also seem subjectively cooler.
Taking out 1 blade makes you pull 10% less power, thus if your power supply is struggling at full load, removing 1 card could give it the margin it needs. When the enermax PSU goes into overload, to power it back on you'll need to have it plugged in and on and remove the jumper, count to 5 and put them jumper back in. This requires the case to be removed...again lol
