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.

Opening the iPhone 7 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.

  • 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 3.4 mm pentalobe screws on the bottom edge of the iPhone.

Can anyone confirm 7/7P's pentalobe screws have a ring of seal near the screw head?

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.

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.

The glass is completely cracked and the suction cup doesn't work because it gets air in between. any tip?

Display is glued and doesn't come off.

A wide, single strip of packing tape, well placed, will solve this for you. :)

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.

Pull the display assembly slightly 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.

Just FYI, if you have an iFixit set with the PH000 you can use that bit to remove the Y000 if you're in a bind.

These screws just spin for me. They don't back out, but the heads aren't stripped either. I've tried applying backpressure to help lift the screws, but no luck

Use the flat end of a spudger or a fingernail to disconnect the two lower display connectors by prying them straight up from their sockets on the logic board. 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.
