Introduction

This is a prerequisite-only guide! This guide is part of another procedure and isn't meant to be used alone.

Parts

Step 1

Heating the lower edge of the iPhone helps soften the adhesive securing the screen, making it easier to open.
Apply a heated iOpener to the bottom edge of the screen to loosen the adhesive underneath. Apply the iOpener for at least 2 minutes.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the device. The edge should feel slightly too hot to the touch.

Step 2

The next two steps demonstrate the Anti-Clamp, a tool we designed to make the opening procedure easier. If you aren't using the Anti-Clamp, skip down two steps for an alternate method.
For complete instructions on how to use the Anti-Clamp, check out this guide.
Pull the blue handle towards the hinge to disengage opening mode.
Position the suction cups near the bottom edge of the screen—one on the front, and one on the back.
Push down on the cups to apply suction to the desired area.
If you find that the surface of your device is too slippery for the Anti-Clamp to hold onto, you can use packing tape to create a grippier surface.

Step 3

Push the blue handle away from the hinge to engage opening mode.
Turn the handle clockwise until you see the cups start to stretch.
Make sure the suction cups remain aligned to each other. If they begin to slip out of alignment, loosen the suction cups slightly and realign the arms.
Wait one minute to give the adhesive a chance to release and present an opening gap.
Insert an opening pick under the screen when the Anti-Clamp creates a large enough gap.
If the Anti-Clamp doesn't create a sufficient gap, apply more heat to the area and rotate the handle clockwise half a turn.
Don't crank more than a half a turn at a time, and wait one minute between turns. Let the Anti-Clamp and time do the work for you.
Skip the next step.

Step 4

Apply a suction handle to the bottom edge of the phone, while avoiding the very edge of the glass.
Pull up on the suction handle with firm, constant pressure to create a slight gap between the front panel and rear case.
Insert an opening pick into the gap.
The adhesive holding the screen is very strong; creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, apply more heat, and gently rock the screen up and down to weaken the adhesive until you create enough of a gap to insert your opening pick.

Step 5

Apply a heated iOpener to the left edge of the screen to loosen the adhesive underneath. Apply the iOpener for at least 2 minutes.

Step 6

Slide the opening pick around the lower left corner and up the left edge of the iPhone to slice through the screen adhesive.
Don't insert the opening pick more than 3 mm into the iPhone, or you may cause damage to internal components.

Step 7

Apply a heated iOpener to the right edge of the screen to loosen the adhesive underneath. Apply the iOpener for at least 2 minutes.

Step 8

Re-insert your pick at the bottom edge of the iPhone, and slide it up the right side to continue separating the adhesive.
Don't insert the pick more than 3 mm inside your phone, or you may damage the display cables.

Step 9

Apply a heated iOpener to the top edge of the screen to loosen the adhesive underneath. Apply the iOpener for at least 2 minutes.

Step 10

Insert your pick underneath the top right edge of the phone. Slide it around the top-right corner and half way across the top edge stopping right before the earpiece speaker cut-out.
Don't insert the pick more than 2 mm or you may damage the front sensor array.

Step 11

Insert your pick underneath the top-left edge of the phone. Slide it around the top-left corner and half way across the top edge stopping right before the earpiece speaker cut-out.
Don't insert the pick more than 2 mm or you may damage the front sensor array.
Don't try to fully separate the screen yet, as several fragile ribbon cables still connect it to the iPhone's logic board.

Step 12

Remove your suction handle from the screen.
Open your iPhone by swinging the screen up from the right side, like the front cover of a book.
Lean the screen against something to keep it propped up while you're working on the phone.
If you don't have anything at hand to lean the screen against, your suction handle can do the trick.
During reassembly, lay the screen in position, align the clips along the top edge, and carefully press the top edge into place before snapping the rest of the screen down. If it doesn't click easily into place, check the condition of the clips around the perimeter of the screen and make sure they aren't bent.

Step 13

Use a Y000 screwdriver to remove the 0.9 mm-long screw securing the display connector bracket.
Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your iPhone.
During reassembly, this is a good point to power on your iPhone and test all functions before you seal the screen in place. Be sure to power your iPhone back down completely before you continue working.

Step 14

Grasp the screw hole end of the connector bracket with a pair of tweezers.
Lift the the bracket slightly to loosen the latch on the other edge.
Remove the display connector bracket.
During reassembly, make sure the bracket latches properly.

Step 15

Use the pointed end of a spudger to disconnect the display cable by prying the connector straight up from its socket.
To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

Step 16

Use a Y000 screwdriver to remove the 0.9 mm-long screw securing the front sensor connector bracket.

Step 17

Grasp the screw hole end of the connector bracket with a pair of tweezers.
Lift the the bracket slightly to loosen the latch on the other edge.
Remove the front sensor connector bracket.
During reassembly, make sure the bracket latches properly.

Step 18

Use the pointed end of a spudger to disconnect the front sensor cable by prying the connector straight up from its socket.

Step 19

Remove the screen.
Apply new adhesive where it's necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
During reassembly, pause here if you wish to replace the screen adhesives.

Conclusion

If possible, turn on your device and test your repair before installing new adhesive and resealing.

To reassemble your device, follow these instructions in reverse order.

The best way to secure the new screen is to apply a sheet of custom-cut double-sided tape to the frame and place the screen back in its original position.

Take your e-waste to an R2 or e-Stewards certified recycler.
