Introduction

Use this guide to replace a malfunctioning power and volume button cable—this includes the switches responsible for volume up and down, the ring/silent control and the power switch, as well as a microphone and the dual-LED flash. Follow this guide if you are looking to replace the exterior power button cover and this guide for the exterior volume control button cover.

  1. iPhone 7 Power and Volume Control Cable Replacement, Pentalobe Screws: step 1, image 1 of 1
    • 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. iPhone 7 Power and Volume Control Cable Replacement, iPhone 7 Opening Procedure: step 2, image 1 of 1
    • 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. iPhone 7 Power and Volume Control Cable Replacement: step 3, image 1 of 2 iPhone 7 Power and Volume Control Cable Replacement: step 3, image 2 of 2
    • 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.

    • 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.

    • Twist the spudger to widen the gap between the display assembly and the rear case.

    • Slide the flat end of the spudger up the right side of the phone to break up the adhesive holding the display in place.

    • Do not insert the spudger further than the adhesive to avoid damaging delicate ribbon cables along the right edge.

  8. iPhone 7 Power and Volume Control Cable Replacement: step 8, image 1 of 2 iPhone 7 Power and Volume Control Cable Replacement: step 8, image 2 of 2
    • Pull up on the suction cup to lift up the display and open the iPhone.

    • Do not raise the display more than 10º as there are ribbon cables along the right edge of the device connecting the display to the logic board.

  9. iPhone 7 Power and Volume Control Cable Replacement: step 9, image 1 of 1
    • Pull up on the small nub on the suction cup to remove it from the front panel.

    • 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.

    • Remove four tri-point Y000 screws securing the lower connector bracket, of the following lengths:

    • Three 1.2 mm screws

    • One 2.4 mm screw

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your iPhone.

  12. iPhone 7 Power and Volume Control Cable Replacement: step 13, image 1 of 1
    • Remove the lower connector bracket.

    • Make sure the battery is disconnected before you disconnect or reconnect the cables in this step.

    • Use 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.

    • If you have a blank screen, white lines on the display, or partial or complete lack of touch response after reassembling your phone, try disconnecting and carefully reconnecting both of these cables and make sure they are fully seated.

Hello,

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

thanks

Martin - Reply

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

reymito sanchez -

Well theres 2 hours of my life I’m not getting back, worked a treat though…
