Once the adhesive is loosened slowly lift the screen starting torward the top of the display and make sure to slide the displays ribbon cable through the slot in the display housing.

Once you get to the bottom of the display you will need to also slide the flex cable through its slot in the displays housing as well.

It is a little trickier to get the home button flex cable through its opening so be patient and do not use to much force. You have to kind of zig zag it out so be careful.
