Insert a SIM eject tool, bit, or straightened paper clip into the SIM card tray hole on the top edge of the phone.
Press the SIM eject tool into the SIM card tray hole to eject the SIM card tray.

Be sure to power off your device before you begin your repair.
Heat an iOpener and apply it to the bottom edge of the back cover for two minutes.
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.

Secure a suction handle to the bottom edge of the back cover, as close to the edge as possible.
If the back cover is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.
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 iOpener instructions to avoid overheating.
Insert an opening pick into the gap you created.

Insert a third opening pick at the bottom right corner of your phone.
Slide the opening pick along the right edge of your phone to slice the adhesive.
Leave the opening pick in the top right corner to prevent the adhesive from resealing.

When you slice near the camera assembly, insert only the tip of the opening pick (~4-5 mm) to avoid damaging or smearing the camera.
Insert a fourth opening pick underneath the top right corner of your phone.
Slide the opening pick along the top edge to slice the adhesive.
Leave the opening pick in the top left corner to prevent the adhesive from resealing.

Heat an iOpener and apply it to the left edge of the back cover for two minutes.

Remove the back cover.
During reassembly:
This is a good point to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.
Remove any adhesive chunks with a pair of tweezers or your fingers. Use some high concentration (over 90%) isopropyl alcohol to wipe away any adhesive residue.
