Chosen Solution

So I did the unthinkable, I broke something a phone not soon after I got it. While I was changing the housing for the GNex, I forgot to remove the SIM card and it jammed the volume flex cable, and it ended up being severed. I just ordered replacements parts on http://www.parts4repair.com/samsung-gala…, but I tried to find any help or information on how to reattach a new flex cable, however there seems to be no information. iFixIt does say that the volume flex cable is soldered to the main board, but that’s about it. So my question is, how should I proceed to re-solder a new volume flex cable? I have some experience but I have never done something so “risky”… Am I better off finding a repair shop?

You can certainly do it yourself if you have some soldering experience. We have a guide for repairing soldered connections that covers how to deal with surface mount soldered connections like the ones for the volume cable. The procedure is going to be very similar to replacing the battery in an iPod Touch.
