Prepare an iOpener and apply it to the bottom edge of the back panel for one minute.
-
-
-
Apply a suction cup to the heated edge of the back panel by pressing down on it to create suction, as close to the edge as possible.
-
-
-
Pull up on the suction cup with strong, steady force to create a gap between the back panel and the frame.
-
Insert the point of an opening pick into the gap.
-
-
-
Slide the opening pick across the bottom towards the left corner to slice the adhesive.
-
With the pick still inserted, slide it from the bottom left corner over to the bottom right corner to completely slice the bottom side adhesive.

Leave the pick inserted in the bottom right corner to prevent the adhesive from re-sealing.

Slide the opening pick up towards the top of the phone, slicing the right side's adhesive.
-
Stop when you reach the top right corner, and leave the pick inserted.
-
-
-
Slide the third opening pick around the top right corner and across the top side of the phone, slicing the final strip of adhesive.
-
-
-
Once you have sliced around the perimeter of the phone, carefully lift the right edge of the back cover, opening it like a book.
-
Do not try to pull the panel all the way off yet, as it is still connected to the phone.
-
-
-
Continue swinging open the back panel until you can rest it on the left edge the phone, being careful not to put any stress on the attached ribbon cable.
