I was just about to spend $129 on a second-generation trackpad, but I decided to give this guide a try. It took me longer than the 3-5 minutes estimated in the guide, but I now have a working unit again! One thousand thanks to the author - and to the guy who suggested drilling a hole to get to the Torx screw. I did that after I took the bottom plate off. Two minutes with a Dremel, and I’ll never have to pop the bottom off again.
