I also seem to have broken my wireless charging after removing the back. I had missed the middle snap that Scott mentioned, but snapping this only made it work intermittently for a few days. It is now back to not working at all, and I can see nothing mechanically wrong. I'll be interested to see if you find a fix.... Edit: I seem to have found the problem in mine. After taking the back off several times, and looking at it under the microscope, I finally noticed something. Where the needle is pointing you can see a small brown spot on the top of one of the springy contacts. This picture was taken _after_ I scraped off a dark brown mass that looked like it had melted on. (Note to self - take before pictures too...) My theory as to what happened is that when I put the back on without a good contact (the middle snap loose) there was some arcing that melted/oxidized the contact. This prevented good contact from being made. Now that I have scraped that off (which was pretty hard to do), it seems to be working...
