1. This is not a how-to repair, I have no idea what Im doing, running on pure can-do spirit here.
2. Yes I know I fucked up and I do feel like a retard, thank you for not pointing out the obvious.

Yesterday evening I swapped out one heat sink because I felt the thermal contact was bad.. the chip was hot, but the corresponding sink was not. When I plugged the board back in and powered up there was was some smoke, a few sparks so I quickly powered down.  Chip #16 on the board had a piece missin where the sparks came out and some burn marks next to it. I had plugged the board in the wron way around. Me.. the person who made the f-ing how to plug them in picture with the instructions clearly stating to double check that the components are facing the Pi.

After some cursing I turned the board the right way around and made a trial run to see how bad things were. At this point I had 4 chips missing. After some inquries here and on irc I proceeded to cut everything leading to the damaged chip. This did not go well and I ended up with 0 chips shoving up.. after this I attempted to solder the cut SJxx traces together with a soldering iron several magnitudes too large (the only one I have at hand) ..with hands that are far from being steady enough for anything like this. Things do not go well! I manage to plant a solid ball of solder on the  SJxx traces, clumping them all together. I figure what the hell, lets try it out, it's dead. I rip off the ball of solder and proceed to carefully try and scrape the cut traces I have pushed too deep in to the board clean. This leads me to having chip #1 show up and work. Im pretty clueless at this point, but figure Im moving in the right direction and try to clean things up a bit more. It does not help, cant remember if one or naught chips were working at this point. I allready write the board off in my mind but do continue thinking about solutions and eventually come up with a plan of sanding the burnt chip and everything around it down. I protect everything I havent allready broken with electric tape and proceed to sanding the damaged part. After about 30 minutes of sanding Im not happy with the result, but do feel that it wont get any better. So I clean up all the shawings, remove the tape and fire up the board: 14 chips on the damaged board show up and hash. likeaboss.jpg

The question that now haunts me is how unsafe is it to keep running this board ?
