Plus What tools you will needed to disassemble
the iPhone 7 Plus: • Screwdriver set
• Plastic mediator • Tweezers
• Suction cup for removing display • Adhesive tape for restore water protection
• Hairdryer and new home button
In the description under the video, I left links where you can buy all the necessary
tools and replacement parts for the iPhone 7 Plus
If Touch-ID doesn’t work on your iPhone 7 Plus and the home button doesn’t respond,
I’ll show you how to replace it Turn off the iPhone and remove the SIM card
tray.
Remove the two screws near the charging port with a Pentalobe 0.8mm screwdriver
Take a hairdryer and heat the display surface for 1-2 minutes.
Set the suction cup near the home button and pull up the ring.
Next, take the plastic mediator and begin to disconnect the display from the case of iPhone
On the top of display, inside there are two latches that attached to the case, so you
need to pull the display down and unstick the display from top.
The case of iPhone 7 Plus opens like a book, that is, open the display to the right.
Now take a Tri-Wing 0.8mm screwdriver and remove 4 screws on the lower metal panel and
3 screws on the upper metal panel.
First, disconnect the battery cable from the mainboard and after disconnect three display
cables.
Now let's begin to remove the home button, unscrew the 4 screws and remove the metal
bracket.
Next, you need to disconnect the button cable from the cable of the display module.
Take the tweezers and pressing the display cable a little, turn off the cable for the
home button.
Now you need to peel off the cable of the home button from the surface of the display
module.
Take something thin, but not sharp, and start peeling off the cable.
If you can’t pry at all, heat the surface of the cable with a hairdryer and continue
to peel off.
Now I explain why you cannot just replace the Home button with any another original button
This is because your original home button is tied to the motherboard from the factory
where your iPhone 7 Plus was assembling.
That is, when replacing the original “Home” button with any other button, the Touch-ID
function (fingerprint) and pressing it - will not work.
But there are two ways to solve this problem: 1) You can restore the original home button.
For example, in many cases the button stops working due to problems with the cable, and
the button can be restored by replacing the cable, which is taken from other original button
But here you need a high level in repair experience.
If the problem is not in the cable, or the button is lost or cannot be restored, then
let's begin to the second option.
2) There is one way how to get the working home button responsive to pressing and you
do not need to solder anything.
There are home buttons that are identical to the original button.
The only drawback of this button is that the Touch-ID fingerprint will not work.
This button connected directly to the display cable and it works like the original button
to press.
This button is also universal and works on iPhone 7, 7 plus, iPhone 8 and iPhone 8 plus.
I left a link where to buy such a button in the description under the video.
Now I gonna show how it works in practice.
Install the button on the display module and connect to the display cable.
Install a metal bracket and fasten 4 screws.
The display assembled and now connect it to the iPhone and check how the new home button
works.
Please note that first 3 display cables are connected, and lastly a battery cable.
Turn the display over and turn on the iPhone.
As you can see, the iPhone show message that the Touch ID function does not work, but the
button works fine.
This the button doesn't have a physical pressing like on the iPhone 6s.
This home button responds to a touch and has the same slight vibration when pressed as
the original home button.
If you look closer, the button sits perfectly in case like original.
If the smartphone is working fine, you can begin to the final stage of iPhone 7 Plus
assembly with restoring of water resistance.
Remove the
adhesive tape from the back cover of iPhone.
Now take a cotton swab and medical or isopropyl alcohol, and wipe the iPhone back cover from
the remnants of glue.
Now take a waterproof adhesive tape and put it on the iPhone case.
Using this adhesive tape, you restore resistance to dust and water.
First, connect three display cables to the mainboard of the smartphone, and then connect
the battery cable.
Install metal panels and fasten the screws.
Turn the display over and push it to the back cover.
Fasten the last 2 screws near the charging connector.
Install the SIM card and turn on the iPhone.
I hope this video was useful to you and helps repair your iPhone 7 Plus.
