Introduction

It’s important to note that each iPhone’s logic board and Touch ID fingerprint sensor are paired at the factory, so replacing the logic board will disable Touch ID unless you also install a replacement home button that has been properly paired to your new logic board.

You can also use this guide to replace the following parts:

  • Audio Control Cable BracketTop Center Cell Antenna BracketNFC Bracket

What you need

Step 1

              Pentalobe Screws
  • Before disassembling your iPhone, discharge the 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 either side of the Lightning port.

Step 2

              Opening Procedure
  • Optionally, apply mild heat to the lower edge of the iPhone using an iOpener or hair dryer for about a minute.
  • Heat softens the adhesive securing the display, making it easier to open.

Optionally, apply mild heat to the lower edge of the iPhone using an iOpener or hair dryer for about a minute.

Heat softens the adhesive securing the display, making it easier to open.

Step 3

  • Opening the display on the 6s Plus separates a thin strip of adhesive around the perimeter of the display. If you prefer to replace the adhesive, have a set of new adhesive strips ready before you continue. It’s possible to complete the repair without replacing the adhesive, and you probably won’t notice any difference in functionality.
  • Apply a suction cup to the lower left corner of the display assembly.
  • If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

Step 4

  • Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.
  • Pulling too hard may damage the display assembly. Apply just enough pressure to create a small gap between the display assembly and the rear case.

Step 5

  • The safest place to pry from is the notch in the front panel above the headphone jack.
  • While still maintaining pressure on the suction cup, insert the flat tip of a spudger into the gap, directly above the headphone jack.

Step 12

  • Gently grasp the display assembly and lift it up to open the phone, using the clips at the top of the front panel as a hinge.
  • Open the display to about a 90º angle, and lean it against something to keep it propped up while you’re working on the phone.
  • Don’t open the display more than 90º—it is still connected to the top of the phone by the display, digitizer, and front camera cables which can tear easily.
  • Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.
  • In a pinch, you can use an unopened canned beverage to support the display.

Great guide thanks. I just want to ask: Does screw length include the head or not? If not, what’s the best way to measure those tiny screws? I have digital calipers but measuring them is quite awkward.

Jeff Suovanen - May 22, 2017

Measurements are for the entire length of the screw, including the head. Putting the whole screw into a digital caliper should give you a reading very close to what you see here.

Hi there! Great guide. Thank you. I was wondering if you ever removed the metal shields? If yes, how? I want to try to fix a water damaged phone.

Thanks!

Hey so I’m having a Problem with my iPhone 6s plus it won’t respond to my Finger touch> i cleaned it , i Hold Lock and Home Button and nothing still same thing, i also Restored cause that what apple Suggested to do if none of those steps worked. Please Guys i need help on this one i really don’t wanna pay a whole 500$ for a new iPhone.

Scott C - Nov 9, 2018

i would replace the main logic board, make sure the board comes with the touch ID, as they are programed to work with the board. You will see main logic boards cheaper without the Touch ID. don’t buy that. I had to replace mine, and all is good now. If you are not good with working with installing the main logic board, buy one and have someone help you that knows how to do that.
