Separate the front glass panel can be tricky, it's glue to the frame. Mine was cracked pretty badly so I won't come out in one neat little piece. Just patiently peel off the screen slowly.

Make sure to mark what ZIF connector goes where, they are not interchangeable even though a first glance the appear to be the same size
