Even if you are lucky to have received a working S2, can you be confident that there is no fire hazard?
I'd be monitoring it for at least the first ten hours.
Later I'd consider turning it off when I'm not at home. If it'd be turned on at night, I'd definitively have a smoke detector in the same room as the S2 and made sure it's loud enough to wake me up.

You don't think Bitmain has tested these things for at least 48hrs before shipping them out? They've had these for weeks, if not months already... personally I wouldn't worry.

Well, since so many S2's have been damaged in shipment, you don't know the extent of loose cables etc.
But, what the heck, if you're willing to risk burning down your house, that's your decision. Cheesy

Obviously one would check for loose cables and boards, but if it's not seriously damaged then there's not much that can go wrong. The PSU will have safety switches to trip if there's a short and if it's serious it'll probably not even power on. It's not that I'm willing to risk burning down my house, I'm just not prone to unwarranted FUD.

can someone upload a working backup so i can reflash?

I am dumping the SD image right now, will compress/upload when completed.

I got one from a distributor but I've not tested it yet ... working on that now.

Thank you Sir. I don't have an S2, but I'm curious and would like to download it... I also have a raspberry pi that I haven't powered up in a while.

I always thought the S2 would look like the S1. I guess im wrong.

Anyone whose S2 is working? How's the ventilation of it?

thanks, and how do i get it on the system if i cant access it at alll....remove the sd card? and copy onto it?

I recommend that you don't touch the factory SD card. Buy a new one and use that to flash the image. It has to be an image copy as it's a bootable image.

Damn, such a bummer to see how some of the units are arriving... looks like UPS is training a juggling school at the same time as doing deliveries Grin

I wouldn't put all the damage down to UPS though, this unit has a lot more mass than the S1 and therefore more inertia when being transported so one would expect some padding for the boards inside the case. It's possible to do serious damage to the components inside with a little shaking of the box which wouldn't leave any traces on the outside of box itself (serious turbulence could do that). I do remember seeing some KNC units that had the same problem and needed to be opened and checked before they would run.

I just hope they sort these issues before shipping batch 2 out on Monday Wink

So how many people have received their S2's and are happily mining and have not had any issues ? Im curious to see as im sure others are...

For the loose boards, in my opinion, they can be dislocate by someone shaking it, not only someone chucking/hitting it.

Has bitmain said anything about all of these issues to anyone ?

They are online.

Although Bitmain has slow customer response, they do impress me with their S1. Before they say anything about the issues i will not judge them. I am sure they will address all the affected customers. they are a good company so far.

Linux never seems to load on the BBB. I haven't tried this with the BBB included with the unit, but possibly a bad firmware image?

this thread looks like a car crash.
I feel for you guys, hope you can get something back for your troubles. I was pondering making an order here, but think i'll pass... the only viable company now has to be those spoondly-thingymajigs. but more expensive than I have in the bank, but i'm going to save for that.
