Fails to include removing the vibration motor from the original board, a necessary (if easily worked out) step. It’s also kind of a useless guide given that the parts required are very difficult to find the correct version of, not helped by iFixit not stocking any despite it being a very commonly needed part.

(why motorola felt the need to make at least a dozen different versions of the super-tiny PCB that contains the common-failure point USB port I have *no* idea.)
