This step is incorrect and should be changed. There is no way to slide anything into that space except a straight edge razor blade or something just as sharp and sturdy. Once the blade is firmly in place, you can then slip in an opening pick and remove the blade. From there, everything else is accurate.

The instructions were perfect. I did use a few different tools for my own preference but anyone can improvise a little on this project. Had no issues. You have to go slow and be methodical. This is not an easy tear-down but not nearly as difficult as you might think. Of course hand/finger size may come into play. I was successful on my first attempt. You not only need to be mechanically inclined but have some knowledge of electronic assembly, in general. Not for the inexperienced unless you learn quickly.
