Introduction

Follow this guide to replace the logic board in your iPhone 16 Pro.

The logic board has connectors on top and below itself. As a result, you may need to remove the screen to re-connect it.

You'll need replacement back glass adhesive to complete this repair.

After you complete this guide, calibrate authentic Apple replacement components using Repair Assistant.

Tools

Step 1

Allow the phone's battery to drain below 25%, as a charged lithium-ion battery is a potential safety hazard.
Unplug any cables from the phone.
Hold the power and either volume buttons and slide to power off the phone.

Step 2

If the screen or back glass is badly cracked, lay overlapping strips of packing tape over the glass to protect yourself and make disassembly easier.
Make sure there's a smooth area near the bottom edge that's big enough for a suction cup to stick to.

Step 3

If inserted too far, an opening pick can damage your device. Follow this step to mark your pick and prevent damage.
Measure 3 mm from the tip and mark the opening pick with a permanent marker.
You can also mark the other corners of the pick with different measurements.
Alternatively, tape a coin to a pick 3 mm from the tip.

Step 4

Use a P2 pentalobe screwdriver to remove the two 7.4 mm‑long screws on either side of the USB-C port.

Step 5

Apply a heated iOpener to the bottom edge of the back glass for two minutes.
Alternatively, you can use a hair dryer or heat gun to heat the bottom edge of the back glass until it's hot to the touch.
Be careful not to heat the phone hotter than this—the battery is susceptible to heat damage.

Step 6

Apply a suction handle to the bottom edge of the back glass, above the USB-C port.
Pull up on the handle with a strong, steady force to create a gap between the back glass and the frame.
Insert the tip of an opening pick into the gap.

Step 7

As you slice the adhesive securing the back glass in the next steps, be careful of the following areas:
There's a delicate cable connecting the back glass to the phone, right next to the volume up button. Don't insert your pick here to avoid slicing the cable.
There are multiple spring contacts around the perimeter of the phone. Be extra careful not to insert your pick deeper than suggested in each step to avoid bending these contacts.
If you damage the spring contacts, gently bend them back with a spudger or opening pick so they align with their gold contact pads on the back glass.

Step 8

Don't insert your pick deeper than 5 mm on the bottom edge to avoid damaging the spring contact.
Slide your pick back and forth along the bottom edge to separate the adhesive.
Leave your pick inserted in the bottom right corner to prevent the adhesive from resealing.

Step 9

Heat the right edge of the back glass until it's hot to the touch.

Step 10

Slide your pick around the bottom right corner and halfway up the right edge, or until you feel a hard stop at a clip securing the back glass.
Don't slice near the volume buttons to avoid damaging the wireless charging/flash cable.
Leave this pick inserted to prevent the adhesive from resealing.

Step 11

Heat the right edge of the back glass until it's hot to the touch.

Step 12

Insert a second opening pick at the bottom edge.
Slide the second pick around the bottom left corner and along the left edge of the screen to separate the adhesive and release the metal clips.
You'll hear and feel the metal clips release as you pass them.
Leave this pick inserted at the top left corner to prevent the adhesive from resealing.

Step 13

Heat the top edge of the back glass, including the area around the volume buttons, until it's hot to the touch.

Step 14

Don't insert your pick deeper than 3 mm along the top edge to avoid damaging the spring contacts.
Slide your opening pick across the top edge and around the top right corner to the volume up button to separate the adhesive.
You'll hear and feel clicks as the top two clips release.

Step 15

Don't try to fully remove the back glass just yet—it's still attached with a delicate ribbon cable. Follow the next few steps to remove it safely.
If the back glass doesn't swing open easily, don't force it—go back around the perimeter with your pick to check for missed sections of adhesive or stuck clips.
You may need to lift the back glass up slightly before swinging it open to fully disengage the clips.
Gently swing open the back glass towards the volume buttons.
Support the back glass with a clean, sturdy object like a small box to avoid straining the cable.
Remove the opening picks.
Consider using polyimide tape to protect the rear camera lenses while you're working inside the phone. Don't push against the lenses to avoid damaging the delicate stabilizers.

Step 16

Use a tri-point Y000 screwdriver to remove the three screws securing the lower connector cover:
Two 1.2 mm‑long screws
One 1.0 mm‑long screw

Step 17

Use tweezers or your fingers to pick up and remove the lower connector cover.

Step 18

Use the point of a spudger to pry up and disconnect the battery press connector.
During reassembly, align the connector carefully over its socket and press down with your fingertip or the flat end of a spudger—first on one side, then the other—until it clicks into place. Don't try to force the connector into place. If you're having trouble, reposition it and try again.

Step 19

Use a tri-point Y000 screwdriver to remove the four screws securing the upper connector cover:
Two 1.0 mm‑long screws
One 1.2 mm‑long screw
One 1.6 mm‑long screw

Step 20

Use tweezers or your fingers to pick up and remove the upper connector cover.

Step 21

Use the point of a spudger to pry up and disconnect the back glass press connector.

Step 22

Lift the back glass off the frame and remove it.
During reassembly:
This is a good point to test your repair before sealing up the phone. Temporarily reconnect the battery and back glass (before replacing the adhesive), power on the phone, and make sure it works as expected. Power it back down, disconnect the battery, and continue reassembly.
Use this guide to reapply adhesive and install the back glass.

Step 23

The 5G mmWave antenna is only in United States and Puerto Rico iPhone 16 Pros (model A3083). For all other models, skip the next four steps.
Use the point of a spudger to pry up and disconnect the earpiece speaker and 5G mmWave antenna press connectors, located on the top right corner of the logic board.

Step 24

Use a Phillips screwdriver to remove the six screws securing the earpiece speaker:
Three 1.2 mm‑long screws
Two 1.8 mm‑long screws
One 1.7 mm‑long screw

Step 25

Insert the point of a spudger in the bottom-right corner of the earpiece speaker and pry it up to remove it.
You may feel some resistance near the top edge, where the speaker gasket seals against the frame. Pull the speaker out gently to release the seal.
During reassembly, insert the top edge of the earpiece speaker into its cutout at a downward angle before pressing it flat to the frame.
You may have to lift the camera slightly to get the earpiece speaker in its cutout. Insert the antenna and earpiece speaker cables to the right of the front camera cables, then gently press the front camera into its cutout before pushing its cables flush with the rear cameras.

Step 26

Use a spudger to pry up and disconnect the press connectors from the top of the logic board:
Seven silver connectors
Three black connectors
One of the black connectors is under the two silver connectors on the left edge of the board.

Step 27

Standoff screws are best removed using a dedicated standoff screwdriver or driver 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.
Use a standoff screwdriver to remove the four screws securing the logic board:
Two 4.5 mm‑long screws
One 3.4 mm‑long screw
One 4.2 mm‑long screw

Step 28

This image shows the display connector underneath the logic board with the board removed. The next two steps show how to disconnect this connector from the logic board.
During reassembly, you can't directly connect the display connector to the bottom of the logic board without removing the screen, but you might successfully connect it by screwing the logic board in place.
Make sure the logic board rests in place against its screw posts. The posts will properly align the board to the display connector underneath it.
Continue with reassembly until you've reconnected the battery. Try to power on the iPhone to see if the screen's connected. If the screen fails to turn on, follow the screen guide to manually reconnect the display connector.

Step 29

If the iPhone has a SIM card tray, eject it before you proceed.
USA model iPhones (A3084) don't have a SIM card tray.
Make sure all the connectors are disconnected from the top of the logic board before proceeding.
Insert the flat edge of an opening pick between the battery and the logic board. Hold the pick in place with your fingers.

Step 30

Don't remove the logic board yet. There's still a cable connected to the bottom side.
Insert the flat end of a spudger underneath the right edge of the logic board.
Gently pry with the spudger and opening pick to lift the logic board and disconnect the screen connector.

Step 31

Pick up the bottom edge of the logic board, flip it up towards the top of the phone, and hold it steady vertically.
Use the point of a spudger to pry up and disconnect the front sensor connector from the underside of the logic board.

Step 32

Remove the logic board.
