10. Carefully lift the phone assembly out of the back cover.
11. During reassembly, this is a good point to power on your phone and test all functions before reinstalling the back cover. Be sure to power your phone back down completely before you continue working.

25. Apply a heated iOpener to the screen to loosen the adhesive underneath. Apply the iOpener for at least two minutes.

26. Once the screen is warm to the touch, apply a suction handle to the bottom edge of the phone.

44. Use the plastic card to cut the adhesive beneath the center of the screen by sliding it to the bottom edge of the phone.
45. Try not to remove the display all the way yet, the display cable is still threaded through the frame and possible adhered on the inner side of the midframe.
