Introduction

This guide was created using the A2894 (international) model. If you’re fixing a different iPhone 14 Pro Max model, there may be some visual discrepancies, but the procedure should be the same.

You’ll need replacement adhesive to reattach the screen when reassembling the device. Your device will function normally, but will most likely lose its IP (Ingress Protection) rating.

What you need

Step 1

              Remove the pentalobe screws

Power off your iPhone before beginning disassembly.
Remove the two 6.8 mm-long pentalobe P2 screws at the bottom edge of the iPhone.

Step 2

              Heat the bottom edge of the iPhone

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 3

              Insert an opening pick

Apply a suction handle to the bottom edge of the screen, 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 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 opening pick.

Step 5

              Slice the left edge adhesive

Slide the opening pick around the lower left corner and up the left edge of the iPhone, slicing through the adhesive holding the screen in place.
Don’t insert the pick more than 3 mm inside your phone, or you may damage the display cables.

Step 9

              Slice the top edge adhesive

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 panel sensor array.

Step 10

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.
Again, don’t insert the pick more than 3 mm or you may damage the front panel 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 11

              Open the iPhone

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 12

              Unfasten the battery connector cover screws

Use a Y000 screwdriver to remove the eight screws securing the battery connector cover:
Six 1.3 mm-long screws
One 1.6 mm-long screw
One 1.9 mm-long screw
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

              Disconnect the battery

Use the pointed end of a spudger to disconnect the battery cable by prying the connector straight up from its socket.
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 15

              Disconnect the display cables

Use the pointed end of a spudger to disconnect the first 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.

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

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 these instructions in reverse order.

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