Introduction

Is your phone not detecting your charging cable? Does your charging port feel loose? It might be time to replace your Lightning connector assembly. Use this guide to replace the Lightning connector assembly which includes the lower microphones, antenna cable, and Lightning connector.

Note that this repair does require a fair amount of disassembly, and it will require time and caution.

  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 3.4 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.

  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 a minute in order to soften up the adhesive underneath.

  3. Attach a suction cup to the lower half of the display assembly, 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.
    • Attach a suction cup to the lower half of the display assembly, 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.

  4. Pull up on the suction cup to create a small gap between the display assembly and the rear case. Insert the flat end of a spudger into the gap. The watertight adhesive holding the display in place is very strong, and creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, rock the screen up and down to weaken the adhesive until you can fit a spudger inside.

To reconnect these cables, press down on one end until it clicks into place, then repeat on the opposite end. Do not press down on the middle. If the connector is even slightly misaligned, the connector can bend, causing permanent damage.

Prob to discourage people from replacing it themselves instead of sending to apple

Ho un problema dopo aver installato il nuovo connettore. Quando l’iphone e scarico, inserendo il cavo, appare sul display il simbolo batteria. Una volta acceso il cavo non viene più segnalato e la ricarica non continua. Cosa può essere?

Can I use this one for the Iphone 8 too ? I havent found one for the Iphone 8.

@manulkamul Not sure if you mean the guide or the part, but in both cases the answer is, unfortunately, no—the 8 is a different animal.
