Can you take a better close up picture with good light and without flash? If there are tracks left you could easily scratch some of the insulation, and rework it with flux. That job was done by caveman though...

is it a 5 or a 7 ghs jalapeño?

If you are going to auction it I would start with a more humble price and see where it goes, like 1 btc, at a reasonable price I might be interested.

Exactly, if you were going to auction it, I'd say starting at 1BTC would be smarter, since it is damaged & it is going to take some work. As like I said earlier, they're going for 2.5BTC-4BTC randomly, especially now that people seem to be receiving them somewhat. Heck, there was a local on craigslist that sold one for $200 (with nothing wrong with it and damn it, I wish I had seen that sooner, I was a day late). So, used, broken but possibly fixable, I wouldn't ask near the going rate, even though that's the low side of the going rate. (That's my opinion and what I would do if i couldn't fix it and in your situation.)

Yeah I said $500 when I thought it was more fixable. I'll auction it really low soon and let everyone know.

Had this happen to a Lorex baby monitor of mine.

I was able to fix it with a temp controlled soldering iron and a pencil thin tip. 

Ultimately, it will break again if you ever want to use it.  It's a weak point in the design...

Did you refund the buyer back fully? I mean its kinda the shipping fault, but also the buyers fault too...

Yeah he bought two. I refunded one fully. It was insured but I doubt usps will approve it. I can't show shipping broke it.

Just took a look at the pics. That repair is going to be fun. My guess is the repair person used a big soldering iron at way too high a temp, the pad just fell off. Probably easier to do a bypass wiring at this point.

Ah well. Do-able with air tools, but not simple. I've repaired blown up IGBT drivers that did things like that, at least there are no shorts inside the board :-)

And as a side note: I took apart my Jally this evening for the daily flashing of the code (can't help it, tweak tweak) and noticed that with the board on the floor and a USB cable plugged in that any pressure on the board would cause a serious amount of torque on the USB plug. So I put my board sideways so it would not break.

I could see that happening by accident. Pretty easily. So if you're tweaking, be careful of that connector outside the box; it has limited support.

I'll be honest, I would probably bid on it... I've got some creative ways of fixing things like this (as I've done in the past), but it's still a pretty decent crapshoot imo, putting that in perspective, I'm not sure how far I would go on bidding on it.

Good Lord! I've resoldered one of these sockets on a dash camera with a 60w unregulated braising soldering iron and done a better job than that! The dashcam also worked afterwards too. I'd get either a short socket on a cable and solder the lines direct to the traces or FTDI chip, or remount the socket to the PCB with glue then run some fine enameled wire to either the traces on the board or the FTDI chip...

Probably should put something here.... Maybe an LTC address?

Likewise, if for nothing else I can float off the BGAs and put them on my Jally. However like everything else in the bitcoin world, it's a matter of calculations:

Estimated chance of repair * value of unit in mining bitcoins=max price you should pay.

Given that difficulty is screaming up, time to repair needs to be factored in as well as these things are losing their ability to make value by the second. Then again that is reflected in "value of unit" :-)

And of course add in the "entertainment factor" for being able to play with one. But the emotional factor of "oooh I have a jally!" would be zero for me since I have one, so it will probably go to someone who wants a jally at any cost less than what you can get it for on Ebay.

I went through the same mental math with a block erupter on Tuesday. I'm going to strap it to my house's water pipe inlet and use it to pre-heat water, so it has a practical value (hah). :-)

Looks like the pads are totally gone.

Ask BFL for the other points on the board that are tied to the same nets as the USB pins.  Then, have someone that knows what they are doing solder small wires to those points, and then to a socket.

My Foxconn mini-PCs use a short pigtail and then a bulkhead connector on its own bracket for the external wifi antenna in order to avoid exactly this problem.

pretty much yea, I don't have one, so it would give me a reason to fix it and I do have some creative ideas on this one... I've repaired a lot of issues like this, but I've had some new things I've been wanting to try

Glad to see it's going to auction. Did you try anything else on it before giving it up for a new home?
