Mine broke, too. None of the repair shops in my area do soldering, so I may be SOL. I spilled water on my laptop and a bunch of keys shorted out. I read online from numerous sources that replacing the keyboard yourself isn't hard, so I figured i'd try it. I am majorly disappointed. Suggestion for iFixit: upload a video of someone disconnecting the fan cable connector. Clearly Apple didn't design it to be easy to remove, and your description is inadequate, given how many people have broken theirs.
I accidentally dislodged the right speaker / subwoofer cable connector as well as the fan cable connector. I know for the fan cable connector there is a warning about how easy it is to dislodge, but there should be more pictures to describe exactly how to avoid doing so. I can live without the right speaker / subwoofer, but my logic board cannot survive long without a fan. I'm trying to see if I can find someone who will try to solder the cable connector back on, but no one in my area will, so I may need to send it out (a local repair shop owner recommended a guy he's used to fix iPad backlights.) I am probably SOL, though. A new logic board is quite pricey... Had I known that it was so difficult to replace the keyboard on your own, I would have paid the $200 for a local repair shop to fix it. I found iFixit helpful but ultimately misleading. I may end up having to get a new laptop altogether. How upsetting.
