Do you need to remove the front display assembly to replace the daughterboard? From the images it appears you just have to go in through the back glass to do this job. Confused.

You do, because the midframe is adhered to both the front and back. It won't come off if you just take off the back.

Flint Green -

You don't have to take screen off. Just disconnect battery.
