In the following steps, you will need to use an iOpener in order to warm the adhesive holding the display assembly to the rest of your phone. This way, you can remove the screen of your device more safely and easily. Remember to clean your microwave before putting the iOpener in it and make sure that the iOpener is clean, too. Heat the iOpener for one minute only, at the highest power setting. When it cools down, reheat it for a minute at a time. Be careful not to overheat the iOpener, and always wait at least two minutes before reheating it. When you pull out the iOpener, be sure to hold it by its tag or a corner.

Put the iOpener on the left side of the phone for at least 90 seconds.

Reheat the iOpener, and repeat the procedure for the right side of your phone.

In the following steps, you will need to use an opening pick in order to remove the adhesive holding the front panel glass. Follow the instructions and pry only when you are told. If you encounter any resistance, reapply the iOpener and try again.

Push the edge of an opening pick under the bottom right side of the front glass.

Move the opening pick along the right side of the display.

Slide the pick around your phone's corner gently, and stop before the speaker grille, located at the top of the phone.

There is a narrow strip of adhesive above the earpiece speaker securing the top of the phone. Move the pick along the top of the speaker in order to avoid damaging internal components.

Slide the pick across the top of the phone. Be extremely careful not to push the pick in too deeply.

Slide the pick around the upper left corner carefully.

If you experience any resistance from the adhesive, reapply the iOpener to the left side of the phone, and try again.

Move the pick down the left half the phone. Stop once you get to the lower left corner.

Make sure that the pick is securely placed and then slide it to the bottom left corner of the phone.

In the following step, you will need to place the iOpener over the home button end of your phone. You do not want your opening pick to slip out.

Put the reheated iOpener over the bottom part of the display assembly.

This part of the phone holds delicate components, so make sure the adhesive is warm and easy to loosen. Otherwise, you can damage your phone.

The soft button and home button ribbon cables are located at the bottom end of your phone. Bear in mind that these cables can be easily damaged in case you push the pick in too far.

Move the end of the pick across the bottom edge of the display in order to remove the remaining adhesive.

You will need to twist the pick to detach the glass from the phone.

In case you find it hard to remove the front panel, you might need to cut the adhesive a bit more.

If you cannot detach the front panel with ease, you might need to separate the adhesive on the soft button cable.

Bear in mind that these cables are thin and can be easily damaged. This is why you need to make sure that you are only peeling them off the assembly, and not cutting them.

Push the pick under the soft button icons on the display and lift the button cables from the inside of the front panel.

Lift, but do not remove, the home button part of display assembly.

Do not remove the front panel completely, because it is still attached to your phone by a connector.

If you plan on reusing the home button flex cable, make sure not to cut the cable from the home button. Adhesive can rip the cable and the home button apart. If this happens, your home button will still work, but the fingerprint scanner will not.

Pull the long sides of the silver bezel gently away from the phone in order to separate the two halves of the midframe.

It might be easier to push in from the side of the battery compartment. However, be careful not to flex the interior half of the midframe, because the motherboard is mounted on it.

Do the same thing on the right side of the bezel - pull the sides away from the interior section of the midframe.

Lift any remaining corners out of the bezel with a plastic opening tool.
