To disassemble the iPhone 8 Plus you need the following tools:
• Screwdriver set • Plastic mediator

Before disassembly, turn off the iPhone and remove the tray with the sim card.

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.
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.
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.
Let's begin to replacement of the motherboard iPhone 8 plus, first unscrew the 2 screws

Next, unscrew 2 more screws and remove a similar metal panel.
Now unscrew the 4 screws on the upper left antenna and one screw on the inner end of
the iPhone case.
Remove 2 more screws.
Unscrew the 3 screws and disconnect the two camera cables from the motherboard.
Now you need to unscrew the 3 screws with a special screwdriver, which has in our How-Fixit
ONE screwdriver set.
If you don't have such a screwdriver, you can try to unscrew this screw with a flat
screwdriver.
Unscrew the last screw on the motherboard and unplug any remaining cables.
Now you can remove the motherboard from the iPhone case.
What needs to know when you replacing the motherboard on an iPhone 8 plus.
If you decide to replace the motherboard and you want a fully functional smartphone with
fingerprint function (Touch ID) you need to replace the home button.
The problem of replacing is that the motherboard tied to the home button from the factory where
your iPhone was assembled, and when installing a new motherboard, your old button will not
work with the new motherboard.
You need to buy a new motherboard together with a native button.
In the description under the video, I left the links where you can buy a new motherboard
for iPhone 8 plus.
When you buying a motherboard, pay attention to this sticker.
If the sticker is red, it means the motherboard was damaged by water then restored during
the repair process, and this is not the best option to buy.
Beginning to the assembly, do all the steps as shown in the video.
The motherboard installed and now you can connect the display and test the iPhone before
final assembly.
To check the functionality of all smartphone functions, it is enough to connect three cables
from the display module and then the battery cable.
Turn over the display, turn on the phone and check how the iPhone works.
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.
