Introdução

Follow this guide to replace the Wi-Fi diversity antenna and flex cable for your iPhone 8. This may help resolve connectivity issues.

Opening the iPhone 8 will damage the waterproof seals on the display. If you do not replace the adhesive seals, your phone will function normally, but will no longer be water-resistant.

Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

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 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.

The screen on my phone was so broken, a suction cup did not work, so I softened the adhesive with a blow dryer and used a Jimmy to carefully pry open the phone from the bottom just enough to slip a pick in.

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.

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.

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.

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.

Not Y000 this time haha

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.

Use the point of a spudger to pry the lower display connector out of 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.

Slide an opening pick under the antenna flex cable to hold the socket down. Use the point of your spudger to pry up and disconnect the antenna flex cable from its socket, using the opening pick to hold the socket down. 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 straight down on the connector with the flat of your spudger until it clicks into place.
