Introduction

The Taptic Engine produces your iPhone's vibration and haptic feedback functions. Follow this guide to remove and/or replace the Taptic Engine in an iPhone 11 Pro.

Step 1

Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
Power off your iPhone before beginning disassembly.
Remove the two 6.7 mm-long pentalobe screws at the bottom edge of the iPhone.
Opening the iPhone's display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.

Step 2

Heating the lower edge of the iPhone helps soften the adhesive securing the display, making it easier to open.
Use a hairdryer or heat gun or prepare an iOpener and apply it to the lower edge of the iPhone for about a minute in order to soften up the adhesive underneath.

Step 3

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 iPhone—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 4

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 two steps.

Step 5

If you're using a single suction handle, apply it to the bottom edge of the phone, while avoiding the curved portion of the glass.
If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

Step 6

Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.
Insert an opening pick into the gap.
The watertight adhesive holding the display in place 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 tool.

Step 7

Slide the opening pick around the lower left corner and up the left edge of the iPhone, slicing through the adhesive holding the display in place.
Don't insert the opening pick too far into the iPhone, or you may cause damage to internal components.

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 very far, or you may damage the display cables along this side of the iPhone. Insert it only a few millimeters, or about the width of the display bezel.

Step 9

The top edge of the display is secured with both glue and clips.
Gently pull the right edge of the display down slightly (in the direction of the Lightning port).
Insert your pick into the top-right corner of the phone.

Step 10

Continue pulling the display down (toward the Lightning port) as needed in order to make a gap large enough for the pick.
Slide the pick to the top left corner and cut any remaining adhesive securing the display.
Again, don't insert the pick more than a few millimeters—about the width of the display bezel—or you may damage the front panel sensor array.

Step 11

Pull on the small nub on the suction cup to remove it from the front panel.

Step 12

Open the iPhone by swinging the display up from the left side, like the back cover of a book.
Don't try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone's logic board.
Lean the display against something to keep it propped up while you're working on the phone.
During reassembly, lay the display in position, align the clips along the top edge, and carefully press the top edge into place before snapping the rest of the display down. If it doesn't click easily into place, check the condition of the clips around the perimeter of the display and make sure they aren't bent.

Step 13

Remove two 1.3 mm long Y000 screws securing the battery cover 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 display in place. Be sure to power your iPhone back down completely before you continue working.

I have the Mako Driver kit. The Y000 in that doesn’t work. it doesn’t seem to work for these screws. Almost feel like the tip needs to be ground down to fit the Y screw.

German translation says "3 screws” but there are only 2.

Step 14

Remove the bracket.

Step 15

Use a spudger or a clean fingernail to pry the battery connector up from its socket on the logic board.
Try not to damage the black silicone seal surrounding this and other board connections. These seals provide extra protection against water and dust intrusion.
Bend the connector slightly away from the logic board to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.

Step 16

Use a Y000 driver to remove six 1.3 mm screws securing the logic board cover bracket.

Step 17

Remove the bracket.

Step 18

Use a spudger or a fingernail to disconnect the OLED panel cable connector.
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 19

Use a spudger or a fingernail to disconnect the front sensor assembly cable connector.
Use a spudger or a fingernail to disconnect the digitizer cable connector.
If any part of your screen doesn't respond to touch after your repair, disconnect the battery and then re-seat this connector, making sure it clicks fully into place and that there's no dust or other obstruction in the socket.

Step 20

Remove the display assembly.
During reassembly, pause here if you wish to replace the waterproof adhesive around the edges of the display.

Between steps 20 & 21, use a Y000 driver to remove two 1.3 mm screws securing the sensor cable cover bracket, then carefully remove the long and narrow bracket.

Step 21

Use a Y000 driver to remove the four 1.5 mm screws securing the lower battery connector cover.

Step 22

Remove the lower battery connector cover.

Step 23

Use a spudger to disconnect the lower battery flex cable by prying it straight up from its socket.

Step 24

Use a spudger to disconnect the Taptic Engine flex cable by prying it straight up from its socket.

Step 25

Remove the three screws securing the Taptic Engine:
One 1.9 mm-long Y000 screw
One 1.4 mm-long Y000 screw
One 4.1 mm-long standoff screw
Standoff screws are best removed using a standoff screwdriver or bit.
In a pinch, a small flathead screwdriver will do the job—but use extra caution to ensure it doesn't slip and damage surrounding components.

Step 26

Remove the Taptic Engine.

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

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