Introduction

If your iPhone 14 Pro Max screen is cracked, not responding to touch, or not showing a picture when your phone is powered on, use this guide to restore your iPhone to working order with a new screen, a.k.a. display assembly.

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

For your safety, discharge the battery below 25% before disassembling your device. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

Note: True Tone and auto brightness functionality are disabled after a screen replacement, even when using an original Apple screen. Face ID is also disabled unless the iPhone runs iOS 15.2 or newer.

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.

  1. iPhone 14 Pro Max Screen Replacement, Remove the pentalobe screws: étape 1, image 1 de 2 iPhone 14 Pro Max Screen Replacement, Remove the pentalobe screws: étape 1, image 2 de 2
    • Power off your iPhone before beginning disassembly.

    • Remove the two 6.8 mm-long pentalobe P2 screws at the bottom edge of the iPhone.

  2. iPhone 14 Pro Max Screen Replacement, Heat the bottom edge of the iPhone: étape 2, image 1 de 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.

    • 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.

  4. iPhone 14 Pro Max Screen Replacement, Heat and separate the screen adhesive: étape 4, image 1 de 1
    • Apply a heated iOpener to the left edge of the screen to loosen the adhesive underneath. Apply the iOpener for at least 2 minutes.

  5. iPhone 14 Pro Max Screen Replacement, Slice the left edge adhesive: étape 5, image 1 de 3 iPhone 14 Pro Max Screen Replacement, Slice the left edge adhesive: étape 5, image 2 de 3 iPhone 14 Pro Max Screen Replacement, Slice the left edge adhesive: étape 5, image 3 de 3
    • 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.

  6. iPhone 14 Pro Max Screen Replacement, Heat and separate the screen adhesive: étape 6, image 1 de 1
    • Apply a heated iOpener to the right edge of the screen to loosen the adhesive underneath. Apply the iOpener for at least 2 minutes.

    • 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 opening pick more than 3 mm into the iPhone, or you may cause damage to internal components.

  8. iPhone 14 Pro Max Screen Replacement, Heat the top edge of the iPhone: étape 8, image 1 de 1
    • Apply a heated iOpener to the top edge of the screen to loosen the adhesive underneath. Apply the iOpener for at least 2 minutes.

  9. iPhone 14 Pro Max Screen Replacement, Slice the top edge adhesive: étape 9, image 1 de 3 iPhone 14 Pro Max Screen Replacement, Slice the top edge adhesive: étape 9, image 2 de 3 iPhone 14 Pro Max Screen Replacement, Slice the top edge adhesive: étape 9, image 3 de 3
    • 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.

  10. iPhone 14 Pro Max Screen Replacement: étape 10, image 1 de 3 iPhone 14 Pro Max Screen Replacement: étape 10, image 2 de 3 iPhone 14 Pro Max Screen Replacement: étape 10, image 3 de 3
    • 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.

  11. iPhone 14 Pro Max Screen Replacement, Open the iPhone: étape 11, image 1 de 3 iPhone 14 Pro Max Screen Replacement, Open the iPhone: étape 11, image 2 de 3 iPhone 14 Pro Max Screen Replacement, Open the iPhone: étape 11, image 3 de 3
    • 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.

    • 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.

    • Grasp the connector cover with a pair of tweezers and slide it downwards to clear the flex cables.

    • Remove the connector cover.

  13. iPhone 14 Pro Max Screen Replacement, Disconnect the battery: étape 14, image 1 de 2 iPhone 14 Pro Max Screen Replacement, Disconnect the battery: étape 14, image 2 de 2
    • 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.

  14. iPhone 14 Pro Max Screen Replacement, Disconnect the display cables: étape 15, image 1 de 2 iPhone 14 Pro Max Screen Replacement, Disconnect the display cables: étape 15, image 2 de 2
    • 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.

  15. iPhone 14 Pro Max Screen Replacement: étape 16, image 1 de 2 iPhone 14 Pro Max Screen Replacement: étape 16, image 2 de 2
    • Use the pointed end of a spudger to disconnect the second display cable by prying the connector straight up from its socket.

  16. iPhone 14 Pro Max Screen Replacement, Remove the screen: étape 17, image 1 de 2 iPhone 14 Pro Max Screen Replacement, Remove the screen: étape 17, image 2 de 2
    • 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.
