Einleitung

Use this guide to remove and replace the logic board in the iPhone SE 2022.

This guide was performed on the A2783 (international) model.

Note: Each iPhone's logic board and Touch ID fingerprint sensor are paired at the factory, so replacing the logic board will disable Touch ID unless you also install a replacement home button that has been properly paired to your new logic board.

This guide includes the removal of the Wi-Fi Diversity Antenna to make the logic board removal and installation easier. However if you feel confident with your repair, you can dispense with these steps and only disconnect the antenna.

If you do not replace the adhesive seals when reassembling, your device will function normally, but will most likely lose its water protection.

You’ll need replacement adhesive to reattach components when reassembling the device.

    • Insert a SIM card eject tool, a SIM eject bit, or a straightened paper clip into the hole on the SIM tray located at the right edge of the phone.

    • Press directly into the hole to eject the SIM card tray.

    • Remove the SIM card tray.

    • Power off your phone before beginning disassembly.

    • Remove the two 3.4 mm pentalobe screws on the bottom edge of the iPhone.

  3. dmLx3jBCnKiqER3P

    • Prepare an iOpener and apply it to the screen for at least two minutes to loosen the adhesive underneath.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

    • Secure a suction handle to the lower half of the front panel, as close to the home button as possible.

    • If the rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.

    • Lift the front panel with the suction handle to create a small gap between the front panel and the frame.

    • If you have trouble creating a gap, apply more heat to the bottom half of the screen to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

    • Insert an opening pick into the gap you created.

    • Slide the opening pick to the bottom right corner to slice the front panel adhesive.

    • Insert a second opening pick at the bottom edge of your phone.

    • Slide the opening pick to the bottom left corner to slice the adhesive.

    • Leave the opening picks in place to prevent the adhesive from resealing.

    • If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener for two to three minutes to reheat it.

    • Slide the bottom left opening pick along the left edge of your phone to slice the adhesive.

    • Stop near the top left corner of the display.

    • Do not try to pry the top edge of the display away from the rear case, as it is held in place by plastic clips that may break.

    • When you slice along the right edge, insert only the tip of the opening pick (~ 2–3 mm) to avoid damaging the display flex cables.

    • Slide the bottom right opening pick along the right edge of your phone to slice the adhesive.

    • Stop near the top right corner of the display.

    • Remove the opening picks.

    • Gently pull up on the suction handle to lift up the bottom edge of the display.

    • Do not raise the display more than 15º or you'll risk straining or tearing the ribbon cables connecting the display.

    • Remove the suction handle.

    • Open the phone by swinging the display up from the left side, like the back cover of a book.

    • Don't try to fully separate the display from the phone assembly yet, as several fragile ribbon cables still connect it to the logic board.

    • Lean the display against something to keep it propped up while you're working on the phone.

  12. 5HQFUu6AmYN4OlAy

    • Remove the four Phillips screws securing the lower display cable bracket:

    • Two 1.2 mm-long screws

    • Two 2.8 mm-long screws

    • Throughout this guide, keep careful track of your screws so that each one goes back where it came from during reassembly. Installing a screw in the wrong place can cause permanent damage.

    • The display and digitizer cables run on top of each other. To avoid cable damage always start by disconnecting the upper cable first and never try to disconnect both at the same time.

    • Use the pointed end of a spudger to disconnect the bottom two display cables by prying the connectors straight up from their sockets.

    • To re-attach press connectors like this, 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 even slightly misaligned, the connector can bend, causing permanent damage.

  16. 4YS3lZFhlKE6BVAT

    • Use a Phillips screwdriver to remove the three 1.2 mm-long screws securing the front sensor assembly bracket.

    • Unfasten the three screws securing the Lighting connector bracket:

    • One 1.2 mm-long Y000 screw

    • One 2.7 mm-long Phillips screw

    • Carefully slide an opening pick between the antenna flex cable and the top of the speaker.

    • This portion of the flex cable is lightly adhered to the speaker. If you're struggling to separate the cable from the speaker, apply a little heat from an iOpener or hair dryer to soften the adhesive. This will make it easier to separate the flex cable safely.

    • Use the pointed end of a spudger to disconnect the Wi-Fi diversity antenna by prying its connector straight up from its socket.

    • The socket of this connector sits loosely between the speaker and the Taptic Engine and it's a bit fiddly to disconnect the cable. To make the disconnection easier, you can use an opening pick to hold down the connector socket during this procedure.

    • Reconnecting this cable can be tricky. Make it easier by using tweezers to hold the flex cable so the connector aligns with its socket. Then, gently press straight down on the connector with the flat of your spudger until it clicks into place.

  27. u1DdOKKeCP4nVHYN

    • Remove the two screws securing the rear-facing camera bracket:

    • One 3.0 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.

    • One 3.1 mm-long Phillips screw

    • Make sure that none of the surrounding cables are tangled with the logic board or blocking its way.

Abschluss

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.
