Insert a SIM card eject tool, a SIM eject bit or a straightened paper clip into the hole on the SIM tray located on the left side of the phone.
Press your SIM card eject tool firmly into the hole in order to eject the SIM card tray.
Remove the SIM card tray.
When reinserting the cards, make sure to properly orient them in the tray.

Apply a heated iOpener to the back cover to loosen the adhesive underneath. Apply the iOpener for at least two minutes.

Secure a suction handle to the right edge of the back cover, as close to the edge as possible.
If the phone's back cover is damaged, 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.
Insert an opening pick into the gap.
In case you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

Slide the opening pick to the bottom right corner and leave it in place to prevent the adhesive from resealing.

Insert a second opening pick at the bottom right corner.
Slide the opening pick along the right edge of your phone to cut the adhesive beneath the back cover.
Leave the opening pick in the top right corner.
At this point of the back cover removal feel free to remove the suction cup or continue to use it for a better grip.

Insert a third opening pick at the top right corner of your phone.
Slide the opening pick along the top edge of your phone to cut the adhesive.
Leave the opening pick in the top left corner to prevent the adhesive from resealing.
If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener to reheat it.

Insert a fifth opening pick to cut the remaining adhesive at the bottom edge of your phone.
In order to cut all the adhesive at the bottom edge of the device, you need to insert the opening pick about 0.4 inch (1cm).

To avoid tearing the fingerprint cable during the following step, make sure to gently press down the fingerprint reader while lifting the back cover.
Fold the back cover upwards and remove it.

Insert an opening pick between the left edge of the phone assembly and the midframe.
Slide the opening pick along the left edge of the phone to release the plastic clips holding the midframe in place.
