Use this guide to replace the large antenna component located in the top left corner of your iPhone 8 Plus, opposite the rear-facing camera.

This guide instructs you to fully detach the display assembly; this is intended to prevent accidental damage to the display cables while you work. If you feel comfortable replacing the antenna without putting undue strain on the display cables, you can skip the steps for detaching the display.

  1. iPhone 8 Plus Top Left Antenna Replacement, Pentalobe Screws: 手順 1、 1の画像 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 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.

  2. iPhone 8 Plus Top Left Antenna Replacement, Opening Procedure: 手順 2、 1の画像 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 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.

    • 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.

    • 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.

    • Slide your pick around the corner and up the left edge of the phone, 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.

    • 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.

  7. iPhone 8 Plus Top Left Antenna Replacement: 手順 7、 1の画像 1
    • 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.

    • Slide an opening pick underneath the display along the top edge of the phone to loosen the last of the adhesive.

  10. iPhone 8 Plus Top Left Antenna Replacement: 手順 10、 2の画像 1 iPhone 8 Plus Top Left Antenna Replacement: 手順 10、 2の画像 2
    • Slide the display assembly slightly down (away from the top edge of the phone) to disengage the clips holding it to the rear case.

    • 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 (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.

  12. iPhone 8 Plus Top Left Antenna Replacement: 手順 13、 1の画像 1
    • Remove the lower display cable bracket.

  13. iPhone 8 Plus Top Left Antenna Replacement: 手順 14、 2の画像 1 iPhone 8 Plus Top Left Antenna Replacement: 手順 14、 2の画像 2
    • Use the point of a spudger to pry the battery connector up from its socket on the logic board.

    • Bend the connector cable up slightly to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.

  14. iPhone 8 Plus Top Left Antenna Replacement, Display Assembly: 手順 15、 2の画像 1 iPhone 8 Plus Top Left Antenna Replacement, Display Assembly: 手順 15、 2の画像 2
    • Use the tip of a spudger or a fingernail to disconnect the large lower display connector by prying it straight up from its socket.

    • To re-attach press connectors like this one, 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.

    • Disconnect the second lower display cable connector, directly behind the one you disconnected in the previous step.

  16. iPhone 8 Plus Top Left Antenna Replacement: 手順 17、 2の画像 1 iPhone 8 Plus Top Left Antenna Replacement: 手順 17、 2の画像 2
    • Remove the two tri-point Y000 screws securing the bracket over the front panel sensor assembly connector:

    • One 1.0 mm screw

    • One 1.2 mm screw

  17. iPhone 8 Plus Top Left Antenna Replacement: 手順 18、 1の画像 1
    • Remove the bracket covering the front panel sensor assembly connector.

    • Remove three Phillips screws securing the upper left antenna component:

    • One 3.1 mm screw

    • The screw boss at the top of the antenna component is tucked into a small recess in the top edge of the iPhone.

    • Tilt the antenna component up towards the top of the phone.

    • Slide the screw boss down and out of its recess.

終わりに

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.
