My Trackpad lost both right and left clicks and I had almost given up on it until I found this tutorial. This guide worked seamlessly to adjust the torx screw and restore my Trackpad’s clicks. I also agree regarding the tightness of the torx screw. Again, patience and steady strong pressure might be required. Excellent and much appreciated.
After reading these comments before following the steps to repair my Trackpad I have to assume the picture that apparently showed the back panel being pried from the wrong side has been replaced because this to me certainly shows the correct steps to remove the back panel of the Trackpad. This repair definitely requires patience and must not be rushed or likely a dead Trackpad will result. Once I pried a corner up enough to see in behind the back panel I used a very small, but long, flat screwdriver to carefully release the adhesive towards the center. I did this first from one side and left a pry tool holding that side open so the adhesive would not just re-stick, and then took the same steps on the opposite side. This resulted in the back panel lifting right off while leaving the CPU chip properly attached to the circuit board.
