Make sure not to pry too much under the flex cable because you will likely damage the gold / silver shining adhesive tape that is located beneath it.
The guide is missing a comment on this and one would not expect the tape there. Check out the photos of step 10 to get an idea of how the tape looks like.

It won't be much of a problem if you damage parts of it though.
But if you peel off / coil up too much of it, it could get too big and the flex cable could get damaged when it's pressed against it.
