Hello everyone, today I show you how to disassemble iPhone 8 Plus and replace home button / Touch ID
To disassemble the iPhone 8 Plus you need
the following tools: • Screwdriver set
• Plastic mediator • Suction cup for removing display
• Tweezers and opening plastic tool • Hairdryer
In the description under this video, I left links to the necessary tools and parts for
replacement.
I also recommend using a magnetic mat when disassembling the iPhone 8 plus and lay out
screws in the order of the disassembly process, because all screws are of different sizes
and it is enough just to get confused during assembly
Before disassembly, turn off the iPhone and remove the tray with the sim card.
Take a screwdriver Pentalobe 0.8mm and unscrew the two screws near charging port.
Take a hair dryer and heat display surface for 1-2 minutes.
Next, fix the suction cup near home button and pull up on the ring.
Take a plastic mediator and try to separate the display from the iPhone.
If you cannot separate using a mediator, you can take a plastic card.
Open the display to the right side like a book.
Unscrew 4 screws and remove the metal panel.
Disconnect the battery cable from the iPhone mainboard.
Unscrew 2 more screws and remove the metal panel.
Now you can disconnect 3 cables of display from mainboard.
To replace the home button (touch id) you need to unscrew the 4 screws on the metal
panel.
Turn over the display and heat the surface of the home button.
Carefully disconnect the home button cable from the display module.
Now gently peel off the cable from the display.
Press down on the button and remove it.
Now I gonna explain why just replacing the "home" button with any other button will not
work as a result.
This is because your original home button connected to the motherboard at the factory
where your iPhone was assembling.
This done for security reasons, and no one else could hack your smartphone by replacing
the button.
If just replace your original home button with any other buttons, the Touch-ID function
will not work.
What to do if your button does not work.
Your broken button can be fixed even in the most difficult cases, but this requires a
high-level repair experience.
If the cable of your button is broken, you can replace it by taking a cable from a similar
button.
These microchips on the cable you can replace and everything will work.
The microchip that is under the metal plate of the backside home button cannot be replaced
or repaired, as I said earlier; it is this chip inside the button that is tied to your
iPhone 8 plus motherboard.
But there is one way how to get the working home button, that is, a button that responds
to a press and returns to the main screen, without having to solder anything.
This home button identical to the original button.
The only drawback of this button is that Touch-ID will not work.
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.
Install the button in the display module and connect the button cable to the display module.
Install the metal bracket and fasten the four screws.
Now let’s check how the new button works before final assembly with gluing of the case.
Connect three display cables to the motherboard and then the battery cable.
Turn the display over and turn on the iPhone Remove the old adhesive tape from the iPhone
case.
Take the medical alcohol and wipe the case.
Also, wipe the display case.
Now begin to restore the water resistance of the iPhone 8 plus.
For this, take a waterproof adhesive tape.
A link to this adhesive tape you can find in the description under
the video.
First, connect 3 cables of the display module to the iPhone 8 plus mainboard and only then
connect the cable from the battery.
Install the metal panel and fasten all the screws.
Turn over the display and press it all the way around the perimeter of the iPhone.
Fasten the last two screws near the charging port and install the sim card tray.
Turn on the iPhone 8 plus and use the smartphone.
