Augh! What is this? Looks like HTC's engineers weren't interested in our input from the M8. They've stuck with their habit of gluing down the motherboard.

After some very gentle prying with a blunt spudger, we manage to free the motherboard and not catch fire.

Phew!

Oh and the rotational vibrator? Yeah, it's now soldered to the motherboard, and (lightly) adhered to the case.
