Introduction

Use this guide to replace a nonfunctioning Lightning connector assembly, including headphone jack, cellular antenna, and microphone.

You can also use this guide for reference when replacing the following parts:

  • Headphone Jack Interconnect Cable
  • Microphone Gasket

The video below includes a few extra steps, including removal of the logic board. Follow the guide steps below it for the updated, shorter procedure.

Video Overview

  1. Before you proceed, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
    • Before you proceed, 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 3.9 mm Pentalobe screws from either side of Lightning connector.

  2. If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass. Lay overlapping strips of clear packing tape over the iPhone's display until the whole face is covered. This will keep glass shards contained and provide structural integrity when prying and lifting the display.

    • This will keep glass shards contained and provide structural integrity when prying and lifting the display.

    • Wear safety glasses to protect your eyes from any glass shaken free during the repair.

  3. In the following steps you will be pulling the display up out of the phone body. The display is composed of a glass screen and a plastic bezel with metal clips. Regardless of the tool you use, you need to be sure you pull up the entire display. If the glass begins to separate from the plastic, as shown in the first image, slide a plastic opening tool between the plastic frame and the metal phone body to pry the metal clips out of the case.

    • If you are reassembling a phone with a separated display bezel, you may want to place a thin strip of adhesive between the plastic bezel and the glass to keep the phone closed.

    • The next two steps demonstrate using the iSclack, a great tool for safely opening the iPhone that we recommend for anyone doing more than one repair. If you aren't using the iSclack, skip the next two steps.

    • Close the handle on the iSclack, opening the suction-cup jaws.

    • Place the bottom of your iPhone in between the suction cups, against the plastic depth gauge.

    • The top suction cup should rest just above the home button.

    • Open the handles to close the jaws of the iSclack. Center the suction cups and press them firmly onto the top and bottom of the iPhone.

  4. Hold onto your iPhone securely and close the handle of the iSclack to separate the suction cups, pulling the front panel up from the rear case. The iSclack is designed to safely open your iPhone just enough to separate the pieces, but not enough to damage the home button cable.

  5. If you don't have an iSclack, use a single suction cup to lift the front panel:
    • If you don't have an iSclack, use a single suction cup to lift the front panel:

    • Press a suction cup onto the screen, just above the home button.

    • Be sure the cup is completely on the screen to get a tight seal.

  6. The front panel is attached with clips, and there are several ribbon cables connecting it to the rest of the phone. Your goal here is to release the clips and open the phone only enough to disconnect the cables. Go slowly and carefully to avoid damage.

    • Make sure the suction cup is firmly attached to the front panel assembly near the home button.

    • While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the home button end of the front panel from the rear case.

    • With a plastic opening tool, gently pry the edges of the rear case down, away from the front panel assembly, while you pull up with the suction cup.

    • Take your time and apply firm, constant force. The front panel assembly is a much tighter fit than on most other devices.

  7. Do not try to completely remove the front panel assembly from the rear case, as there are several delicate ribbon cables connecting them. Pull the plastic nub to release the vacuum seal on the suction cup.

  8. Open the phone just enough to reveal the metal bracket covering the home button cable. Do not open the phone too far or you risk damaging the home button cable, or the socket it plugs into. Keep the cable loose—if it is stretched taut, that's too far. Only the phone's original home button assembly will be capable of using the Touch ID functionality. If you rip the cable, installing a new home button will only restore ordinary home button functions, not the Touch ID features.

    • Use the tip of a spudger to push the bracket free and remove it with tweezers.

    • The next two steps apply to reassembly. Skip them and continue to Step 12 until reassembly.

  9. During reassembly, you will need to reinstall the Touch ID cable bracket. The top of the bracket needs to slide between the battery and Touch ID cable connector, in front of the metal tab. The bottom must latch down over the connector. Slide the top of the bracket over the Touch ID cable connector from left to right.

Can't you replace just the lightning port itself by soldering on a new one?

Josh Bacon - Reply

It's not even worth soldering another one on when it's pretty cheap to buy another charging port flex assembly.

I got through this successfully and it solved my problem (phone wouldn't charge/iTunes wouldn't recognize it when plugged in). With the new part it works perfectly.

Two cautions: I bought a new lightning connector assembly and I had to transfer two items from the old assembly that were not mentioned in the steps.

(1) There is a small black rubber "boot" which you can see in the step 38 photo. (on the very bottom between the lightning port and the headphone jack) Pull this off and put it in the same place on your new lightning connector assembly. It attaches to a fitting on the bottom wall of the aluminum case.

(2) There is a bracket that holds the home button connector socket in place. This is the socket that is exposed when you disconnect the home button cable in step 9. When you remove the old lightning connector assembly, this bracket needs to be transferred to the new assembly. It's attached by a small piece of double sided tape that you can salvage/reuse if you're careful!

Right well that wasn't too much fun. In my case the adhesive connecting the lcd/digitiser and the lcd shield/bracket had gone making opening the device quite difficult. The screen and digitizer were coming up with the suction cup but the lcd shield and the metal bracket with all the clips stayed firmly secured to the main case. My solution was to drive a flat metal prying tool on the battery side between the metal bracket and the inside wall of the main casing. Not for the faint of heart but I got there in the end.

No complaints with the rest of the repair and the iFixit replacement lightning assembly works flawlessly (my lighting port and headphone jack had become loose fitting causing headphones to easily pop out and making charging very difficult).

When all is re-assembled remember to do a hard reset to get touch ID working again as only the home button function works immediately after reassembly (security feature?). Thanks a million iFixit, this brick will live to see another year hopefully :)

Hi Barry,

Can you clarify what type of reset you had to do to get your TouchID working again as like you, only my home button is working after reassembly.

Thanks
