Introdução

Use this guide to replace the small flex cable running from the Lightning connector flex to the logic board in the iPhone 8 Plus. Replacing it may resolve a number of connectivity issues.

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.

  • Opening the iPhone's display will damage its waterproof seals. If you do not replace the seals, your phone will no longer be water resistant.

  • Remove the two 3.5 mm pentalobe screws from the bottom edge of the iPhone.

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.

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.

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.

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.

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.

Use an opening pick to gently separate the adhered portion of the antenna flex cable from the top surface of the speaker. This portion of the flex cable is lightly adhered in place. If necessary, apply a little heat from an iOpener or hair dryer to soften the adhesive. This makes it easier to separate (and re-adhere) the flex cable safely.

Use the point of your spudger to pry up and disconnect the other end of the antenna flex cable from its socket, next to the Lightning Port. Reconnecting this cable can be tricky. Make it easier by using your tweezers to hold the flex cable so the connector aligns with its socket. Then, gently press down on the connector with the flat of your spudger until it clicks into place. Reconnecting this cable can be tricky.

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.
