The logic board, also known as the motherboard, contains the CPU and most of the integrated circuit chips that control the operation of the phone. iPhone X logic boards are notoriously difficult to repair, as they consist of two boards stacked on top of one another and soldered together to form a single unit. Repairing any component sandwiched between the two boards requires them to be disassembled, an additional and difficult step in board repair that is already hard enough and requires microsoldering expertise.

This guide will show you how to replace the logic board.

However, in order to keep the Face ID function working, the Earphone / Proximity Sensor assembly and the front camera assembly, both of which must be paired to the logic board, must also be replaced.

If the loss of Face ID is acceptable, then you can use this guide to to replace the logic board by itself.

  1. iPhone X Logic Board (Motherboard) Replacement, SIM Card: step 1, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement, SIM Card: step 1, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement, SIM Card: step 1, image 3 of 3
    • Insert a SIM card eject tool or a paperclip into the small hole in the SIM card tray, located near the side button on the edge of the iPhone.

    • Press firmly to eject the tray.

  2. iPhone X Logic Board (Motherboard) Replacement: step 2, image 1 of 2 iPhone X Logic Board (Motherboard) Replacement: step 2, image 2 of 2
    • Remove the SIM card tray from the iPhone.

    • The SIM card will fall out of the tray easily.

    • When reinserting the SIM card, ensure that it is in the proper orientation relative to the tray.

    • A thin rubber gasket around the SIM tray provides water and dust protection. If this gasket is damaged or missing, replace the gasket or the entire SIM tray to protect your iPhone's internal components.

  3. iPhone X Logic Board (Motherboard) Replacement, Pentalobe Screws: step 3, image 1 of 1
    • Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Remove the two 6.9 mm-long pentalobe screws at the bottom edge of the iPhone.

    • If the screws are stripped or damaged, replace the screws.

    • Opening the iPhone's display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.

  4. iPhone X Logic Board (Motherboard) Replacement, Opening Procedure: step 4, image 1 of 1
    • Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.

    • Use a hairdryer or heat gun or prepare an iOpener and apply it to the lower edge of the iPhone for about a minute in order to soften up the adhesive underneath.

  5. iPhone X Logic Board (Motherboard) Replacement: step 5, image 1 of 2 iPhone X Logic Board (Motherboard) Replacement: step 5, image 2 of 2
    • The next two steps demonstrate the iSclack, a handy tool that we recommend for anyone doing frequent repairs. If you aren't using the iSclack, skip down two steps for an alternate method.

    • If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger phones like the iPhone X.

    • Position the suction cups near the bottom edge of the iPhone—one on the front, and one on the back.

    • Press both suction cups firmly into place.

    • If your display or back glass is badly cracked, covering it with a layer of clear packing tape may allow the suction cups to adhere. The iSclack also includes two pieces of tape for this purpose.

  6. iPhone X Logic Board (Motherboard) Replacement: step 6, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 6, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 6, image 3 of 3
    • Hold onto your iPhone securely and close the handle of the iSclack to slightly separate the screen from the rear case of the phone.

    • Don't try to completely separate the screen; a small opening along the bottom edge is all you need.

    • Insert an opening pick into the gap.

    • Skip the next two steps.

  7. iPhone X Logic Board (Motherboard) Replacement: step 7, image 1 of 2 iPhone X Logic Board (Motherboard) Replacement: step 7, image 2 of 2
    • If using a single suction handle, apply it to the bottom edge of the phone, while avoiding the curved portion of the glass.

    • If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

  8. iPhone X Logic Board (Motherboard) Replacement: step 8, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 8, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 8, image 3 of 3
    • Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.

    • Insert an opening pick into the gap.

    • The watertight adhesive holding the display 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 tool.

  9. iPhone X Logic Board (Motherboard) Replacement: step 9, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 9, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 9, image 3 of 3
    • Slide the opening pick around the lower left corner and up the left edge of the iPhone, slicing through the adhesive holding the display in place.

    • Don't insert the opening pick too far into the iPhone, or you may cause damage to internal components.

  10. iPhone X Logic Board (Motherboard) Replacement: step 10, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 10, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 10, image 3 of 3
    • 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 pick very far, or you may damage the display cables along this side of the iPhone. Insert it only a few millimeters, or about the width of the display bezel.

  11. iPhone X Logic Board (Motherboard) Replacement: step 11, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 11, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 11, image 3 of 3
    • The top edge of the display is secured with both glue and clips.

    • Slide the opening pick around the top corner of the display, while gently pulling or wiggling the display down in the direction of the Lightning port.

    • The clips will break if you use too much force. Work carefully and be patient.

    • Again, don't insert the pick more than a few millimeters—about the width of the display bezel—or you may damage the front panel sensor array.

    • Slide the pick to the opposite corner and cut any remaining adhesive securing the display.

  12. iPhone X Logic Board (Motherboard) Replacement: step 12, image 1 of 1
    • Pull on the small nub on the suction cup to remove it from the front panel.

    • If you used an iSclack and it's still affixed to the iPhone, remove it now.

  13. iPhone X Logic Board (Motherboard) Replacement: step 13, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 13, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 13, image 3 of 3
    • Open the iPhone by swinging the display up from the left side, like the back cover of a book.

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

    • As pictured, make sure the frame comes off with display and doesn't get stuck in the device.

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

    • During reassembly, lay the display in position, align the clips along the top edge, and carefully press the top edge into place before snapping the rest of the display down. If it doesn't click easily into place, check the condition of the clips around the perimeter of the display and make sure they aren't bent.

    • Remove five Y000 screws securing the logic board connector bracket, of the following lengths:

    • Three 1.1 mm screws

    • One 3.1 mm screw

    • One 3.7 mm 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.

  14. iPhone X Logic Board (Motherboard) Replacement: step 15, image 1 of 1
    • Remove the bracket.

    • The bracket may be lightly adhered in place. Lift gently but firmly to separate it.

    • During reassembly, this is a good point to power on your iPhone and test all functions before you seal the display in place. Be sure to power your iPhone back down completely before you continue working.

  15. iPhone X Logic Board (Motherboard) Replacement: step 16, image 1 of 2 iPhone X Logic Board (Motherboard) Replacement: step 16, image 2 of 2
    • Use the point of a spudger or a clean fingernail to pry the battery connector up from its socket on the logic board.

    • 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.

  16. iPhone X Logic Board (Motherboard) Replacement: step 17, image 1 of 2 iPhone X Logic Board (Motherboard) Replacement: step 17, image 2 of 2

  17. iPhone X Logic Board (Motherboard) Replacement: step 18, image 1 of 2 iPhone X Logic Board (Motherboard) Replacement: step 18, image 2 of 2
    • Use the point of a spudger or a fingernail to disconnect the OLED panel cable connector.

    • 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.

  18. iPhone X Logic Board (Motherboard) Replacement: step 19, image 1 of 2 iPhone X Logic Board (Motherboard) Replacement: step 19, image 2 of 2
    • Use the point of a spudger to pry the digitizer cable connector up from its socket.

    • This connector's recessed location makes it tricky to reconnect. Take your time and align it carefully, then gently press it into place with your fingertip—first one side, then the other. You should feel it click into place.

    • If any part of your screen doesn't respond to touch after your repair, disconnect the battery and then re-seat this connector, making sure it clicks fully into place and that there's no dust or other obstruction in the socket.

  19. iPhone X Logic Board (Motherboard) Replacement: step 20, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 20, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 20, image 3 of 3
    • The front panel sensor assembly flex cable is lightly adhered in place.

  28. iPhone X Logic Board (Motherboard) Replacement: step 29, image 1 of 2 iPhone X Logic Board (Motherboard) Replacement: step 29, image 2 of 2
    • When prying up the speaker, take care not to damage the flex cable you just disconnected. If necessary, hold it to one side so the speaker has room to come out.

    • Insert a spudger under the top edge of the speaker near the edge of the iPhone's case.

    • Gently pry up and lift the top edge of the speaker.

    • When reinstalling the speaker, check the position of the flex cable and make sure it doesn't get trapped underneath the speaker.

  29. iPhone X Logic Board (Motherboard) Replacement: step 30, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 30, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 30, image 3 of 3
    • Hold the speaker by its side edges and rock it side-to-side, separating the adhesive securing it to the bottom edge of the iPhone.

    • Pull the speaker away from the bottom edge of the iPhone until the adhesive gasket separates.

  30. iPhone X Logic Board (Motherboard) Replacement: step 31, image 1 of 2 iPhone X Logic Board (Motherboard) Replacement: step 31, image 2 of 2
    • Remove the speaker.

    • The speaker's adhesive gasket is not reusable. Peel away any remaining adhesive residue with tweezers.

    • To help protect against water and dust intrusion, replace the adhesive gasket during reassembly. Prep the area by cleaning it with a bit of isopropyl alcohol and a lint-free cloth or coffee filter so that the gasket adheres properly. Install a new gasket onto the speaker, and then install the speaker.

  31. iPhone X Logic Board (Motherboard) Replacement, Taptic Engine: step 32, image 1 of 2 iPhone X Logic Board (Motherboard) Replacement, Taptic Engine: step 32, image 2 of 2
    • Remove the 2.3 mm Phillips screw securing the Taptic Engine.

  32. iPhone X Logic Board (Motherboard) Replacement: step 33, image 1 of 2 iPhone X Logic Board (Motherboard) Replacement: step 33, image 2 of 2
    • Use a spudger to disconnect the Taptic Engine flex cable by prying it straight up from its socket.

  33. iPhone X Logic Board (Motherboard) Replacement: step 34, image 1 of 1
    • Remove the Taptic Engine.

  34. iPhone X Logic Board (Motherboard) Replacement, Battery: step 35, image 1 of 1
    • The iPhone X's battery is secured to the rear case by four pieces of stretch-release adhesive—one on the top cell, and three on the bottom.

    • Each piece of adhesive has a black pull-tab at the end, which is lightly adhered to the side edge of the battery.

  35. iPhone X Logic Board (Motherboard) Replacement: step 36, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 36, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 36, image 3 of 3
    • Separate the first battery adhesive tab from the bottom edge of the battery.

    • Each tab has a small loop in the center; insert a tool through the loop if you're having trouble grabbing hold of the tab.

    • Don't jab the battery with any sharp tools. A punctured battery may leak dangerous chemicals or catch fire.

  36. iPhone X Logic Board (Motherboard) Replacement: step 37, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 37, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 37, image 3 of 3
    • Repeat the above step to separate the remaining two adhesive tabs from the bottom edge of the battery.

    • Take care not to damage the speaker cable connector just below the center adhesive tab.

  37. iPhone X Logic Board (Motherboard) Replacement: step 38, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 38, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 38, image 3 of 3
    • In the following steps, you'll pull each tab to slowly stretch out the adhesive underneath the battery. This special stretch-release adhesive loses its tack when stretched and then comes out in your hand, allowing you to lift out the battery with ease.

    • If the strips break, don't panic! They don't always work as intended. Keep reading for some additional steps for removing broken strips.

    • To increase your odds of success:

    • Don't press down on the battery. Hold the iPhone firmly by its sides.

    • Keep the strips flat and unwrinkled as you pull.

    • Pull very slowly, giving the strip time to stretch and separate. It takes around 15-30 seconds of stretching to remove each strip.

    • Pull at a low angle so the strip doesn't snag along the bottom edge of the battery.

    • If a strip does break off underneath the battery and cannot be retrieved, move on to the other strips and then continue with the additional steps below.

  38. iPhone X Logic Board (Motherboard) Replacement: step 39, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 39, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 39, image 3 of 3
    • Grab one of the outer battery adhesive tabs and slowly pull it away from the battery, toward the bottom of the iPhone.

    • Pull steadily, maintaining constant tension on the strip until it slips out from between the battery and the rear case.

    • The strip will stretch to many times its original length. Continue pulling and re-grab the strip near the battery if necessary.

    • If the battery adhesive tabs break during the removal process, use your fingers or blunt tweezers to retrieve the remaining length of adhesive, and continue pulling.

    • If any of the adhesive strips break underneath the battery and cannot be retrieved, try to remove the remaining strips, and then proceed as instructed below.

  39. iPhone X Logic Board (Motherboard) Replacement: step 40, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 40, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 40, image 3 of 3
    • Repeat the previous step to remove the strip on the opposite side, leaving the center strip for last.

  40. iPhone X Logic Board (Motherboard) Replacement: step 41, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 41, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 41, image 3 of 3
    • Remove the center strip, being careful not to snag it on the speaker flex cable.

  41. iPhone X Logic Board (Motherboard) Replacement: step 42, image 1 of 2 iPhone X Logic Board (Motherboard) Replacement: step 42, image 2 of 2
    • The final pull tab lies very close to the Face ID hardware. If damaged, Face ID can only be repaired by Apple, so work with care.

    • Peel and separate the pull tab on the final adhesive strip, on the top edge of the upper battery cell.

  42. iPhone X Logic Board (Motherboard) Replacement: step 43, image 1 of 3 iPhone X Logic Board (Motherboard) Replacement: step 43, image 2 of 3 iPhone X Logic Board (Motherboard) Replacement: step 43, image 3 of 3
    • Pull and remove the final adhesive strip.

    • The strip may fling the battery when it separates from the iPhone, so hold your hand over the battery to secure it—but don't press down on the battery itself, or the added pressure may cause the adhesive strip to break off underneath the battery.

    • If you removed all four adhesive strips successfully, skip the next step.

    • If the adhesive breaks off underneath the battery and can't be retrieved, apply a few drops of high concentration (over 90%) isopropyl alcohol under the edge of the battery in the area of the broken adhesive strip(s).

    • Wait about one minute for the alcohol solution to weaken the adhesive. Use the flat end of a spudger to gently lift the battery.

    • Don't try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.

    • Be careful not to damage the ribbon cables or the wireless charging coil directly underneath the battery.

    • For alternative methods to unstick the battery from the case, continue to the next step below.

  43. iPhone X Logic Board (Motherboard) Replacement, Alternative method to unstick the battery from the case: step 44, image 1 of 2 iPhone X Logic Board (Motherboard) Replacement, Alternative method to unstick the battery from the case: step 44, image 2 of 2
    • If any of the adhesive strips broke off and the battery remains stuck to the rear case, prepare an iOpener or use a hair dryer to heat the rear case directly behind the battery.

    • Heat the iPhone until the rear case is slightly too hot to comfortably touch. Don't overheat the iPhone, or you may accidentally ignite the battery.

    • Flip the iPhone back over and thread a strong piece of string (such as dental floss or a length of thin guitar string) underneath the battery.

    • Wrap the ends of the string around a cloth (or wear gloves) to protect your fingers.

    • Pull the string from side to side in a sawing motion all along the length of the battery to separate the adhesive. This can take some time since the adhesive is slow to deform, but with patience it will come free. Do not deform or damage the battery.

    • If you choose to use pry tools to lift the battery out of the iPhone, use extreme caution or you may damage the ribbon cables or the wireless charging coil directly underneath the battery.

  44. iPhone X Logic Board (Motherboard) Replacement: step 45, image 1 of 1
    • Grasp the battery from the bottom edge and remove it from the iPhone.

    • If there's any alcohol solution remaining in the phone, carefully wipe it off or allow it to air dry before installing your new battery.

    • Reinstall the Taptic Engine and speaker before installing a new battery. This helps keep the battery aligned correctly during installation.

    • Before you adhere the replacement battery, temporarily reconnect the battery connector to the logic board socket. This ensures that the battery is properly aligned in its recess.

    • Adhere the battery, disconnect it, and continue reassembling your device.

    • If your new battery does not come with adhesive preinstalled, refer to this guide for help replacing the adhesive strips.

    • Perform a force restart after reassembly. This can prevent several issues and simplify troubleshooting.

Hi Omar,

In general the answer to that is pretty much always no. Each phone is designed with a customized motherboard made specifically for that phone, along with all of the components inside it. Unfortunately for us, that means there is virtually no possibility of interchange between different models and that holds true for the iPhone X and XS. Each model tends to change the type of parts that are plugged into it, the position of those connections and even the type of connector. Those changes also result in different shapes and mounting points of the logic boards, meaning they won't even physically fit into a different housing.

Hello Jerry,

Hi Ray,

Although it's entirely possible for companies (Chinese ones in particular) to reverse engineer iPhone motherboards and components and make a decent copy, the catch is that Apple controls the firmware that goes on them and there are parts of the software that cannot be duplicated. As a result no one but Apple can make a fully functioning iPhone X motherboard, especially not one that is paired to the Face ID components.

However, there is a large market for phones that have been scrapped and scavenged for parts, so there are a lot of places that sell those. Most of the sellers ensure that the motherboards they sell do not have iCloud or SIM locks in place, but you'll want to verify that the seller states that explicitly. And if you want Face ID to work, you have to buy the paired components that go with the motherboard; specifically the front camera assembly and the earpiece speaker assembly on the display.

Since all the motherboards on the market are used, obviously you can't be 100% sure that every function is going to work correctly, but the reputable sellers will have tested the boards they sell to weed out the ones with issues. The ones sold on AliExpress, for example are generally tested and should have a guarantee of functionality. There are also reputable online stores that sell the parts as well; go through some of the answers forums to get an idea of which companies get recommendations.

eBay can be a good source to save money, but it's definitely a buyer beware situation, depending on the seller. You'll want to verify the IMEI number on an IMEI checking website to make sure the Find My iPhone function is turned off, that it's not iCloud locked and that it's not SIM locked. In general, the boards are pretty reliable so in most cases if it powers up at all, it will usually work.

So it's like buying anything used; you want to find a reputable seller who will guarantee their product.
