Introduction

What you need

Step 1

              Pentalobe Screws

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.

              iPhone 7 Opening Procedure

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.

Step 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.
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 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.

Hello,

how can I disassemble and assemble the mute button from the flex cable. because most spare part cables are without mute button…

thanks

reymito sanchez - Oct 12, 2018

the mute button can slide out. there is space on the side that is not marked red. it looks like three clips hold it in but simply grab hold of the button nob thing with tweezers and slide or wedge it out from underneath that bar that goes around the side with the red line and then once it’s out you can slip that button into the new flex
