Use a plastic opening tool to pry up the plastic midframe connector panel.

There should be enough adhesive to readhere the panel upon reassembly, otherwise use a small amount of double-stick tape.

Use the sharp tip of a spudger to pry the home button cable connector straight up off its socket.

In the following steps you will be using an iOpener to warm the adhesive affixing the display assembly to the rest of the phone. This will allow for a safer, easier screen removal. For proper iOpener use, follow our [invalid guide link], make sure to pay attention to all warnings.

Place a heated iOpener on the left side of the phone for at least 90 seconds.

Reheat the iOpener and place it on the right half of the phone.

In the following steps you will be using an opening pick to separate the adhesive securing the front panel glass. Only pry where directed. If you experience resistance, stop sliding the opening pick and reapply heat.

Insert the edge of an opening pick underneath the bottom right side of the front glass.

Slide the opening pick up along the right side of the display.

Carefully slide the pick around the corner, stopping before the speaker grille at the top of the phone.

The adhesive securing the top of the phone is only a narrow strip above the earpiece speaker. Slide the pick along the top of the speaker to avoid damaging internal components.

Slide the opening pick across the top of the phone, being very careful not to insert the pick too deeply.

Carefully slide the pick around the upper left corner.

If you encounter any resistance from cooling adhesive, reapply a heated iOpener to the left side of the phone.

Slide the opening pick down along the left half of the phone stopping at the lower left corner.

Slide the opening pick all the way to the bottom left corner of the phone, making sure it is securely placed.

In the following step you will be placing an iOpener over the home button end of the phone, you won't want your opening pick to slip out.

Place a reheated iOpener over the bottom portion of the display assembly.

There are delicate components in this portion of the phone, you want to ensure the adhesive is warm and easy to loosen to protect the phone.

The bottom end of the phone contains the soft button and home button ribbon cables. If you insert the opening pick too far into the phone you risk cutting these cables.

Slide the very end of the opening pick across the bottom edge of the display to separate the last of the remaining adhesive.

Twist the opening pick to detach the glass from the phone.

If the front panel does not detach easily, it may require additional adhesive cutting.

If the front panel is not easily freed, the adhesive on the soft button cable may need to be separated.

These cables are thin and easily damaged, therefore be certain you are only peeling them off the display assembly and not lacerating them.

Insert an opening pick under the soft button icons on the display and pry the button cables down off the inside of the front panel.

Slightly lift, but do not remove, the home button end of display assembly.

Do not remove the front panel entirely. It is still attached by a connector.

If you are reusing the home button flex cable, be careful not to sever the cable from the home button. Adhesive can cause the cable to rip apart from the home button. While the home button will still work, the fingerprint scanner will not.
