Step-by-Step Process
Step 1: Heat the back cover
Unplug and power off your phone before you begin.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.
Step 2: Insert an opening pick
Secure a suction handle to the bottom edge of the back cover, as close to the edge as possible.
If the back cover is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken cover.
Lift the back cover with the suction handle to create a small gap between the back cover and the frame.
If you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the [https://www.ifixit.com/Guide/iOpener+Heating/25705|iOpener|new_window=true] instructions to avoid overheating.
Insert an opening pick into the gap you created.
