I would think the Read/Write speed of the class 10 allows the BB to boot smoothly on the USB 2.0 bus. Hope Bitmaintech is making that change @ the factory, could not be much cost as they can handle bulk purchases of class10 microSD's
I tried the image from 1l1l11ll1l but for my it did not work.
win32discimager writes for a few seconds but after that i can't read the sd card.
There was also a other image ( updated? ) and that one worked.
It took a few minutes to write that one.
I have just send a email to bitmaintech to ask about this booting problem.
When i have found the problem i will post it in here.
You will probably need to format the SD card properly before writing the image or it might not work (it's partitioned). Download a SDFormatter to format the card and make sure you see the full memory available before writing the image with win32diskimager.win32discimager writes for a few seconds but after that i can't read the sd card.

Sounds like you got it working though... if you did, you should make an img of the working card and write it to a spare or at least to disk, to make any future resetting go quicker.
btw, the sd card i used came formatted, i will try SDFormatter tonight to be sure.
Thank's for the advice.
Make sure they are class 10 sd cards. That worked for me.
I had the same problem on my batch 2. Three of them just did not boot when restarted. Even after replacing the sd cards with new ones and the image provided by 1l1l11l1l (thanks!) still no boot. But they were not class 10 cards. I don't know why but as soon as I put in a class 10 card in, with the same image, it worked without a problem and on all three.
Good luck
who knows amount of each batch S2?
for AntMiner S2 1TH/s Miner Batch 4 already open sales??
Since yesterday apparently.Edit: be sure to take the diff jump we've just had into consideration: 8,000,872,135.97
for AntMiner S2 1TH/s Miner Batch 4 already open sales??
Yes i can see the files on the SD card, both on the card i made with the diskimager and on the original one.
btw, the sd card i used came formatted, i will try SDFormatter tonight to be sure.
Thank's for the advice.
No problem, happy to share the help and info provided by others around here...btw, the sd card i used came formatted, i will try SDFormatter tonight to be sure.
Thank's for the advice.
Just fyi, it doesn't seem like the card gets completely corrupted, I could also still read it on my pc, it just wouldn't boot the miner. I think it might be corrupting a setting in a config file or boot record somewhere or something that's not very obvious.
Good luck!

I have a Antminer S2 from the second batch, it was all fine for a few day's after putting the blades back like most of you 
Until today, i restarted the damn thing and now there is nothing but blue on the screen.
The original sd card seems to be fine, new msd card with a new image does not help.
I even tried with all the blades out, only one and half of them, still nothing
Do you guy's know what could be wrong?
When I've had this problem, it's been the SD card, try re-imaging it with the image from 1l1l11ll1l. If you need to power your machine down, first eject the card (no need to completely remove it), then power off, then push it back in and power on again. I've had no more problems since following this routine.Until today, i restarted the damn thing and now there is nothing but blue on the screen.

One of my blades showing all ----- with a few ooo but no xxx 
What's going on there? It's the original PSU
EDIT: Is chain 1 on the far left side if I'm looking at the miner from front?
Check my previous posts, I found a missing resistor that needed to be bridged...What's going on there? It's the original PSU
EDIT: Is chain 1 on the far left side if I'm looking at the miner from front?
Chain 1 will be furthest from the PSU, if you look closely you'll see the PCI numbers on the backplane.

I got my miner today and except 3 free spinning screws that I had to break everything inside was in perfect shape. I might know why too. See pictures below.
This rubber padding might have something to do with my miner coming in 1 piece.
Mine also had that rubber on the lid, it didn't help much... the problem is that the documents and stickers are stuck to the side of the box and not the top, which leads to the delivery guys packing them vertically and with one bump it bends the pci connector and dislodges the cards and then they proceed to screw up the little pins inside the connectors.This rubber padding might have something to do with my miner coming in 1 piece.
This could all be avoided by placing the docs on the lid of the box and adding a "fragile" and "this way up" sticker to show which way they should be transported. I'm hoping to see some improvements for batch 3 customers and hope they haven't just stuck to their current packaging.
That hole in the side of the cover for the psu is new though... I guess I'm lucky winter is on it's way down here
Got my two s2's today. Both where fucked up inside, Cards everywhere, bent pci slots. Plastic thingy holding the cards had about 50% survival rate.
After assembling them back together one did not start and one worked at 650Ghs. After some hours of trying different things I got two new PSU's, XFX Black Edition 1250W and RECOM 1600W(Overkill but had it laying around) One are stable at 1Ths the other is working at 920ghs with row 10 showing only lines.
I feel the s2 is a step down from s1 when it comes to build quality and overall design.
Next time pack each cards individually with bubblewrap and stick them inside the miner. Shipping the miner with the cards already in their slot is borderline retarded.
I had the same and found that the card that wasn't registering was missing one of the tiny resistors ("0") closest to the pci connection on the board. I replaced the resistor with some pencil and some silver conductive paint and it's working fine for a week now.After assembling them back together one did not start and one worked at 650Ghs.

Thank you for that, will try it out.
You got picture so I can see? I got no education in electronics so this wil be "monkey see, monkey do" https://i.imgur.com/2Zt1Yen.jpg
It just shows which resistor it was, it's slightly blurry. I've got no education in electronics either, but I saw the corresponding resistor on another board had a "0" on it, so figured it wasn't providing much resistance and just shorted it and it worked. It would have been RMA anyway, so I figured I'd give it a go.
Be careful though, I can't take any responsibility if something goes horribly wrong...

Usually they are used in single layer boards for connections which cannot be routed on copper due to density. In other cases, 0 ohm resistors are used as factory switches, when the same pcb board can be equipped in several variants, and particular connections must exist in each variant. Sometimes they are used as fuses.
Suggests you just need to bridge it.
Good luck Thomas, perhaps glue some copper wire into that bridge too.
Just out of curiosity, has anyone purchased the S2's at the $2199 price even? I'm tempted to if BTC reaches $480+ in the next few days.... thoughts?

Thanks dogie, I will try the wood glue + pencil shavings.

Yes i know, i mined the coins with S1's to buy the S2 on 16-03 for the second batch.
The S1's where great but this
I hope it's something i can solder back, that won't be any problem for me.
Even if it's a bga or something like that.
On the controller board are 5 led's, only one of them is green.
it's the led with R41D5 marking next to it.
Any thoughts?

look up support for the beaglebone black since that is the control module. its possible you need to swap in a new controller and/or sd card (probably <$50)
The real question is: why should anyone have to swap out anything for an expensive piece of equipment that was obviously poorly tested, and used a shitty microSD card in the first place.
Also stop hiring monkies to throw your packafges onto your planes....do they think there are pilows inside an 18kg box? what a stupid system, at least work out the delivery part so all the units dont come to people in pieces.
Fragile, or this side up, doesnt mean shit to these carriers, even if they could read them or understaing which way an up arrow is suppposed to go. Put it in chinese then, but I dont think it will make a difference. seems like whoever he is using to ship these units is the cheapest carrier he could find as seen in one of theose animated gifs i saw a while back where the monkey is tossing these large heavy boxes carelessly on to the conveyor belt with half of them falling off.
Good work Bitmain, way to kill your entire business operations in one clean sweep.
Maybe you shoulod lower the price again next week and try and get some more suckers to give you money.
You can use whichever carrier you want, if you don't package it in a way it can be kicked around without taking damage it's guaranteed to arrive in pieces.
