iPhone X Logic Board (Motherboard) Replacement

Duration: 45 minutes
Steps: 66 Steps

The logic board, or motherboard, is the brain of your phone, housing the CPU and most of the key chips that keep everything running smoothly. iPhone X logic boards are a bit of a tough nut to crack because they’re actually two boards stacked and soldered together as one. If you need to fix anything trapped between these layers, you’ll have to carefully separate them—a tricky step that demands some serious microsoldering skills. This guide walks you through swapping out the logic board. To keep Face ID up and running, you’ll also need to replace the Earphone / Proximity Sensor assembly and the front camera assembly, since they’re paired with the logic board. If you’re okay with losing Face ID, you can use this guide to replace just the logic board. If you hit a snag or want to avoid the headache, you can always schedule a repair.

Step 1

- Grab a SIM card eject tool or even a paperclip—yep, that simple—and insert it into the tiny hole on the SIM card tray, right near the side button of your iPhone.

- Give it a gentle push and watch the tray pop right out. Easy peasy!

Step 2

- Pop out the SIM card tray from your iPhone. Easy, right?

- When you're putting the SIM card back in, make sure it's facing the right way in the tray. A little attention here goes a long way.

- The SIM tray has a tiny rubber gasket that keeps dust and water out. If that little gasket is damaged or missing, your iPhone's internals might not be as safe. In that case, swap out the gasket or the whole tray to keep your device in top shape.

Step 3

- Make sure to power off your iPhone before you start taking it apart.

- Unscrew the two pentalobe screws, each 6.9 mm long, located at the bottom edge of your iPhone.

- If those screws are stripped or looking rough, go ahead and swap them out for new ones.

Step 4

- Mark a spot 3 mm from the tip of your opening pick with a permanent marker. You're setting the stage for a successful repair—let's get this party started!

Step 5

- Cover the iPhone's screen with overlapping strips of clear packing tape until the entire front is protected.

- If the suction cup won't stick in the next steps, no worries! Just fold a sturdy piece of tape (like duct tape) into a little handle and use that to gently lift the screen instead.

Step 6

- Grab the blue handle and pull it back to unlock the Anti-Clamp's arms.

- Slide the arms gently over either the left or right side of your iPhone.

- Place the suction cups at the bottom edge of your iPhone—one on the front and the other on the back.

- Squeeze the cups together to create a firm hold and apply suction where it's needed.

Step 7

- Slide that blue handle forward to lock those arms in place.

- Give the handle a full spin clockwise—360 degrees—until the cups start to stretch out.

- Keep the suction cups lined up with each other. If they start to wander, loosen them up a bit and get those arms back in sync.

Step 8

- Warm up that iOpener and slide it through the arms of the Anti-Clamp like a pro.

- Bend the iOpener so it rests comfortably on the bottom edge of your iPhone.

- Take a breather for a minute to let the adhesive loosen up and create a little opening gap.

- Gently slide an opening pick beneath the screen and the plastic bezel, avoiding the screen itself.

- Feel free to skip the next three steps.

Step 11

- Give that suction cup a confident tug—steady pressure is your friend here. You'll see a tiny gap start to show up between the screen and the frame.

- Slide an opening pick into the space, aiming under the screen’s plastic edge (not the screen itself). You got this!

Step 12

- Gently slide the opening pick around the lower left corner and up along the left edge of the iPhone to carefully cut through the adhesive holding the display in place.

Step 13

Step 14

- Slide your pick back in at the bottom of your iPhone, then cruise up the right side to loosen up that stubborn adhesive. Keep it smooth and steady—you're making progress!

Step 15

- Glide your opening pick around the top corner of the display, gently nudging or wiggling the display downward towards the Lightning port. Smooth moves—no need to rush.

- Take the pick to the other top corner and slice through any leftover adhesive keeping the display stuck. Almost there!

Step 16

- Gently pull on the small nub on the suction cup to lift it away from the front panel.

Step 17

- Swing the iPhone’s display open from the left—imagine you’re flipping a book cover.

- Prop the display up against something sturdy so it doesn’t flop around while you work.

- When you’re ready to put things back together, line up the top edge clips, press the top into place, then snap the rest of the display down. If it’s refusing to click, double-check those surrounding clips; they might need a little straightening.

Step 18

- Let's get those screws out! First, remove five Y000 screws that are holding the logic board connector bracket in place. Here's the scoop on the screws you'll be tackling:

- Three screws measuring 1.1 mm

- One screw that's 3.1 mm

- And finally, one 3.7 mm screw

Step 19

- Take off that pesky bracket!

- Now's a great time to power up your iPhone and check that everything's working like a charm before sealing the display back on. Just remember to turn your iPhone off completely before diving back into the work!

Step 20

- Gently pop the battery connector up from its spot on the logic board using a spudger or a clean fingernail—think of it like opening a stubborn pickle jar, but way less messy.

- Tilt the connector away from the logic board just a bit, so it doesn’t sneakily reconnect and power up your phone while you’re working your repair magic.

Step 22

- Grab a spudger or your trusty fingernail and gently disconnect that OLED panel cable connector. Easy peasy!

- When it's time to reconnect, take your time and carefully align the connectors. Press down on one side until you hear that satisfying click, then do the same on the other side. Just a friendly reminder: avoid pressing on the middle! If you misalign it, those little pins can bend and nobody wants that. If you find yourself stuck, don't hesitate to schedule a repair.

Step 23

- Grab a spudger and pop that digitizer cable connector straight up out of its socket.

- Getting this connector back in can be a bit of a puzzle—it's tucked away! Line it up carefully, then press down with your fingertip, one side and then the other, until you feel it click.

- If your screen is ignoring your touch after the swap, unplug the battery and give this connector another shot. Make sure it clicks in perfectly and double-check there’s no dust sneaking around in the socket.

Step 25

- Take off the display assembly carefully.

- When putting everything back together, take a moment here if you want to swap out the waterproof adhesive around the display edges.

Step 26

- Let's get to work! First, you'll need to take out those seven screws holding the bracket snugly below the Taptic Engine and speaker. Here's the lineup:

- Two Y000 screws, measuring 1.9 mm each

- One Y000 screw that's 1.2 mm

- One Y000 screw at 1.6 mm

- One Phillips screw that's 2.4 mm

- One Phillips screw measuring 1.7 mm

- And finally, one Phillips screw at a cool 1.5 mm

Step 27

- Gently lift the bracket from the edge closest to the battery. No need to yank it off completely; it's still attached with a tiny flex cable.

Step 28

- As you keep the bracket out of the way, gently use the tip of a spudger to lift and disconnect the flex cable hiding beneath it.

Step 34

- Grab the speaker by its side edges and give it a little wiggle from side to side to loosen up that sticky adhesive holding it down at the bottom of your iPhone.

- Gently pull the speaker away from the iPhone’s bottom edge until the adhesive gasket lets go.

Step 35

- Take out the speaker with care, just like you’re unwrapping a surprise gift!

Step 36

- The speaker's gasket is a one-time thing. So, when you're putting it all back together, be sure to swap it out with a fresh one.

- Grab some tweezers and carefully peel off any remnants of the old gasket from both the frame and the speaker.

- Take a microfiber cloth and some isopropyl alcohol to give the frame and speaker a nice, clean wipe to get rid of any leftover adhesive.

- Before you put the new gasket on, make sure you get it lined up correctly. The large cutout should fit around the speaker grille mesh, so double-check that it’s in the right spot.

- Peel off the bigger, clear liner from the gasket and use your tweezers to gently place it in position on the speaker’s bottom.

- Press the gasket down gently with your fingers or a spudger to make sure it sticks properly to the surface.

- Now, take off the remaining liner and carefully place the speaker back in, making sure the connector doesn’t get caught underneath. It’s all about precision here!

Step 39

- Take out the Taptic Engine.

Step 40

- Every strip of adhesive comes with a snazzy black pull-tab chilling at the end, lightly stuck to the battery’s side edge, just waiting for its time to shine.

Step 41

- Gently peel up the first battery adhesive tab from the bottom edge of the battery—think of it like starting a sticker collection, but with way less commitment.

Step 42

- Do the same thing for the last two adhesive tabs along the bottom of the battery—just peel them away gently and keep it going!

Step 43

- Want to boost your chances of success? Here’s how:

- If a strip breaks off under the battery and you can’t fish it out, just switch to the next strip and keep going with the steps below.

- No need to press down on the battery. Just hold your iPhone steady by its sides.

- Keep those strips nice and flat—no wrinkles allowed—as you pull them out.

- Take it slow—pull gently to let the strip stretch and do its thing. Each strip usually takes about 15–30 seconds to come free.

- Pull at a low angle so the strip slides out smoothly without catching on the battery’s bottom edge.

Step 44

- Grab one of the outer battery adhesive tabs and gently peel it away from the battery, heading toward the bottom of your iPhone.

- Keep a steady pull going, applying just the right amount of tension on the strip as it slips free from between the battery and the rear case.

Step 45

- Do the same thing on the other side by peeling off that strip, but hold off on the center strip until last. You got this!

Step 46

- Gently take off the center strip, and watch out for that sneaky speaker flex cable—it can be a bit clingy!

Step 47

- Carefully peel back and pull apart the tab on that last sticky strip located at the top of the upper battery cell. You've got this!

Step 48

- Carefully peel off that last adhesive strip and toss it aside like a pro.

- If you've successfully removed all four adhesive strips, you can totally skip to the next step—you're on a roll!

- Now, give that alcohol solution about a minute to work its magic on the adhesive. Then, using the flat end of your trusty spudger, gently lift the battery out of its cozy home.

Step 49

- If any of the adhesive strips are still stuck to the battery and it's holding on tight to the rear case, grab your iOpener or a trusty hair dryer and heat up the back of the phone where the battery is. Give it a few moments to loosen up.

- Now, carefully flip the iPhone back over and thread a strong piece of string (think dental floss or a thin guitar string) right under the battery.

- Gently saw back and forth with the string, working your way along the length of the battery to slowly separate it from the adhesive. It might take a little time since the glue’s holding on, but stick with it! Just don’t apply too much force and avoid damaging the battery.

- Wrap the ends of the string around a cloth or slip on some gloves to keep your fingers safe and comfy while you work.

- Unscrew the two Phillips mounting screws holding things together.

- Take out the 2.0 mm Phillips grounding screw.

- Lift out that grounding tab like a pro.

- Remove the 2.7 mm Phillips screw.

- Take out the 2.1 mm Phillips screw.

Step 64

- When you pop that SIM card out, a little pin will slide out from the frame and give a gentle nudge to the eject lever in the SIM card carrier. Just give that pin a little push back into the frame so it doesn’t get in the way of taking out the logic board. You're doing great!

Step 65
