Introdução

Follow this guide to replace the Lightning connector assembly, which includes the lower microphones, antenna converter cable, and Lightning connector.

  1. iPhone 8 Lightning Connector Assembly Replacement, Remove the SIM card: passo 1, imagem 1 %32 iPhone 8 Lightning Connector Assembly Replacement, Remove the SIM card: passo 1, imagem 2 %32
    • Insert a SIM card eject tool, bit, or a straightened paperclip into the small hole in the SIM card tray.

    • Press to eject the tray.

    • This may require a significant amount of force. However, ensure the eject tool is properly aligned beforehand as to not damage the eject mechanism inside the phone.

  2. iPhone 8 Lightning Connector Assembly Replacement: passo 2, imagem 1 %32 iPhone 8 Lightning Connector Assembly Replacement: passo 2, imagem 2 %32
    • 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 card tray provides water and dust protection. If this gasket is damaged or missing, replace the gasket or the entire SIM card tray to protect your iPhone's internal components.

  3. iPhone 8 Lightning Connector Assembly Replacement, Remove the pentalobe screws: passo 3, imagem 1 %32
    • 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 on 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.

  4. iPhone 8 Lightning Connector Assembly Replacement, Heat the display: passo 4, imagem 1 %32
    • 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 phone for about 90 seconds in order to soften up the adhesive underneath.

  5. iPhone 8 Lightning Connector Assembly Replacement, Separate the display: passo 5, imagem 1 %32 iPhone 8 Lightning Connector Assembly Replacement, Separate the display: passo 5, imagem 2 %32
    • 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.

  6. iPhone 8 Lightning Connector Assembly Replacement: passo 6, imagem 1 %32 iPhone 8 Lightning Connector Assembly Replacement: passo 6, imagem 2 %32 iPhone 8 Lightning Connector Assembly Replacement: passo 6, imagem 3 %32
    • 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.

  7. iPhone 8 Lightning Connector Assembly Replacement: passo 7, imagem 1 %32 iPhone 8 Lightning Connector Assembly Replacement: passo 7, imagem 2 %32 iPhone 8 Lightning Connector Assembly Replacement: passo 7, imagem 3 %32
    • Slide the opening pick up the left edge of the phone starting at the lower edge and moving towards the volume control buttons and silent switch, breaking up the adhesive holding the display in place.

    • 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.

  8. iPhone 8 Lightning Connector Assembly Replacement: passo 8, imagem 1 %32 iPhone 8 Lightning Connector Assembly Replacement: passo 8, imagem 2 %32 iPhone 8 Lightning Connector Assembly Replacement: passo 8, imagem 3 %32
    • Re-insert your tool at the lower right corner of the iPhone, and slide it around the corner and up the right side of the phone to separate 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.

  9. iPhone 8 Lightning Connector Assembly Replacement: passo 9, imagem 1 %32 iPhone 8 Lightning Connector Assembly Replacement: passo 9, imagem 2 %32
    • Gently pull up on the suction cup 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.

    • Pull on the small nub on the suction cup to remove it from the front panel.

    • 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.

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

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

    • Two 1.3 mm screws

    • Two 2.8 mm 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.

    • Remove the bracket.

  13. iPhone 8 Lightning Connector Assembly Replacement: passo 14, imagem 1 %32 iPhone 8 Lightning Connector Assembly Replacement: passo 14, imagem 2 %32
    • Use the point of a spudger to pry the battery connector out of its socket in the logic board.

    • Bend the battery connector cable 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 8 Lightning Connector Assembly Replacement, Disconnect the display and digitizer: passo 15, imagem 1 %32 iPhone 8 Lightning Connector Assembly Replacement, Disconnect the display and digitizer: passo 15, imagem 2 %32

    • A rubber gasket on the bottom of the Lightning connector protects your iPhone from liquid and dust intrusion. If you are installing a new Lightning connector assembly, you may need to carefully remove and transfer the gasket to the new part.

    • The small adhesive patch on the bottom of each microphone also protects your iPhone from liquid and dust intrusion. For best results, replace the two adhesive patches before installing your Lightning connector assembly.

    • Check to see if your new part comes with an antenna converter cable. If it doesn't, use the point of your spudger to pry up and transfer the cable from your old Lightning assembly to the new one.

Conclusão

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, and follow these instructions in reverse order.

I love how you mention the “antenna converter cable” twice but never show what the &&^& that part even looks like??

I only hate Humans. - Responder

Sorry about that! It’s actually shown in the 3rd image in the last step. I cropped the photo so that it’s zoomed in more to show it.

Arthur Shi -

I would HIGHLY recommend not attempting this fix. I have done a variety of repairs on iPhones (screens, batteries, etc.) and decided to try this to address a broken microphone. I could make regular phone calls but couldn’t use speakerphone or FaceTime. After replacing the lightening charger using the instructions and the iFixit parts, I still can’t use the speakerphone or FaceTime function. To make matters worse, my phone won’t charge through the lightening connector, won’t wirelessly charge, and people can’t hear me even when I make a regular phone call anymore. In other words, I started with one fairly minor problem and, due to this repair, have a whole bunch of new (much more significant) issues. Don’t make the same mistake I did.

Aaron Nelson - Responder

Don’t know about the charging issues, but the reason replacing the microphone didn’t help is because you replaced the wrong microphone.

iPhone 8 has 3 mics.

- One for regular phone calls - which is the one you replaced

- One for the front-facing camera - which is used for the speakerphone and FaceTime and is located near the earpiece

- One for the back-facing camera
