Introduction

The iPhone 8 Plus home “button” is actually a solid-state sensor, which also includes Touch ID (fingerprint recognition) capability.

Most replacement home buttons won’t work, so check carefully before starting your repair. Your iPhone’s original home button is uniquely paired to the logic board at the factory—and without Apple’s proprietary calibration process, even a genuine replacement home button from another iPhone won’t work. To fix a broken home button, you should install a specially-made, universal-style home button. Note that these replacements only work as a button; Touch ID will not function.

If you are only replacing a broken screen, you can use this guide to carefully remove and transfer your working original home button to a new screen, preserving all functions, including Touch ID.

During this procedure, to avoid accidentally straining or tearing the display cables, it's best to completely detach the display assembly before beginning repairs on the home/Touch ID sensor. But if you are comfortable doing so, you may skip the display assembly section of this guide and go straight to the home/Touch ID sensor section.

  1. Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
    • 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 3.5 mm pentalobe screws from the bottom edge of the iPhone.

    • 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.

    what do I do about super stripped screws?

    I’m sorry, your comment slipped past my radar earlier. For future fixers that might see this and ask the same question, you can check out our stripped screw guide for some detailed advice.

    Do you need a toolkit like the essential toolkit

    Adam Palmer - Réponse

    Hi Adam. Having a tool kit with all of the listed parts above is best. The screw heads are very small and each set of screws needs a very specific type of driver to remove them without stripping any of them.

  2. Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.
    • Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.

    • Use a hairdryer or prepare an iOpener and apply it to the lower edge of the iPhone for about 90 seconds in order to soften up the adhesive underneath.

  3. Apply a suction cup to the lower half  of the front panel, just above the home button. Be sure the suction cup does not overlap with the home button, as this will prevent a seal from forming between the suction cup and front glass.
    • Apply a suction cup to the lower half of the front panel, just above the home button.

    • Be sure the suction cup does not overlap with the home button, as this will prevent a seal from forming between the suction cup and front 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.

    Warning ! If you pull too hard (reheat the underside of the display again), you create an gap of air between the glass and the lcd display !

    When you replace the display assembly you end up with gray stains on the display.

    Result: you have to buy a new display (assembly).

    Arnoud - Réponse

    Using just the single suction cup that is included in the battery replacement kit probably wouldn’t open the device. An iOpener and an iSlack should be the recommended method. However, you can get it open with just the single suction cup and iOpener, but does take a lot of time.

    Get an iOpener and iSlack with the battery replacement kit.

    I used a flat x-acto (#18) blade knife tool to gently pry back the screen enough to allow me to insert the pick near the bottom corner. I then worked the pick under the screen as mentioned in steps 5 & 6 below then. This worked really well for me.

    Kyle Luksa - Réponse

    I used the suction cup without heating the phone - the adhesive came away quite easily without applying any heat. Maybe due to age of phone (nearly 4 years old). Worth trying.

  4. 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 or other thin pry tool a few millimeters 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.

    After multiple tries and using a very hot iOpener, it will not open.

    • Remove four Phillips (JIS) screws securing the lower display cable bracket to the logic board, of the following lengths:

    • Two 1.3 mm screws

    • One 1.4 mm screw

    • One 2.7 mm screw

    • 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.

    I got hold of a iPhone 8 Plus with cracked screen that I am planning to fix.

    Here is my problem:

    When I tried to take out the screen from my phone, (step 15-18) I was curious about the new screen, so I tried to connect it. It was completely dead! Then I tried the old cracked one, and suddenly that was dead to! This is a phone that some fool has been inside earlier and changed battery, but I suspect he has done some more really stupid things. The Taptic Engine is living its own life and vibrating every time I slightly touch the home button. (I have a new Taptic Engine) The phone is also full of dust and small particles that does not belong there. One tri-point Y000 screw (step 18) is even missing! Now the biggest problem is that both screens are black! I know the phone is on, because I hear voice command speak when I turn on the power. The screen worked before I tried to change it? And one last thing: My new LCD screen came with new flex cables. Is it possible to switch over, so I can use the old ones?

    Pretty easy to follow instructions if you have patience and careful hands. If you have clumsy hands you will not succeed in fixing any small electronics. There are some small things you should use to help you succeed at fixing small electronics, like some scotch tape or other clear tape to hold some of the cables in place while you work on small electronics items, also a small heavy bottle or object to propped the iPhones cases against to hold them from falling over so that your hands can be free to perform your tasks. Great job you are doing iFixit personel and I am with you all the way with fighting for our rights to fix our electronics equipment.

    • Remove the home/Touch ID sensor assembly by lifting it through the front side of the display.

    • Your replacement part may come with extra Y000 screws already installed near the Home Button. Remove the unnecessary screws so that you can reinstall the home button bracket.

Conclusion

If your replacement screen did not come with a front camera and sensor cable, follow these steps to transfer them over.

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 the above steps in reverse order.

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

ATTENTION: Don’t screw in that one screw over the home button too much, or the button breaks! I just found one proper explanation for it in this YouTube video (https://www.youtube.com/watch?v=rDVnp90a...). Basically, that one screw that goes over the Home button should not be tightened too much, so that the metal plate doesn't bend (which it did for me).
