The #00 Phillips and 2.5 mm flat head screwdrivers that are suggested tools are too big. I needed to use a #000 Phillips and 5/64 in flat head screwdrivers.

Difficulty: MODERATE? Then why is the vibrator replacement guide DIFFICULT? I think these need to be switch around guys...

This repair will destroy your soul. I would not recommend even attempting it without even more specialized tools (eye loupe, headlamp, preternatural patience) as it is extraordinarily easy to ruin your phone with one quick misstep. I've thrown in the towel after weeks of attempting the job. After ripping the screen cable for the second and final time, I'm selling for parts.
