show how to replace motherboard on the iPhone 11
What tools you will needed to disassemble
the iPhone 11:
• Screwdriver set
• Plastic mediator
• Suction cup for removing display
• Tweezers
• Plastic opening tool
• Adhesive tape for restore water protection
• Hairdryer
In the description under the video, you will

replacement parts for iPhone 11
Turn off the iPhone, then take a 0.8 mm Pentalobe
screwdriver and remove the 2 screws near the
charging port.
Take any hair dryer and heat the surface of
the display for 1-2 minutes.
The required temperature for heating is 60-70
degrees Celsius; almost any hair dryer will
be enough to detach the display from the case.
Set the suction cup on the bottom of display.
Take a thin plastic mediator and begin to
disconnect the display from the case.
If you have warmed the surface of the display
well enough, opening process will not be difficult,
in any case, you can additionally warm the
surface of the display.
You can fix the suction cup in the middle
of the display and use it as a support for
the display module.
The case of the iPhone 11 opens like a book,
opening the display to the right.
First you need to disconnect the battery cable,
but in the iPhone 11 it is located under the
metal panel, which holds 3 screws and one
of screw is hard to reach, it's under the
cable of the display module.
So, in order not to break the display cable,
first remove the 5 screws on the large panel,
then disconnect the 3 cables of the display.
After removing the display, remove the 3 screws
on second metal panel and disconnect the battery
cable.
When the battery connected to the main board,
it is not critical to disconnect the display
module, because the most important is to disconnect
the battery when you connecting any module.
Now I’ll show you how to replace the motherboard,
but first I recommend removing the camera
module and Face ID.
Take a Phillips 1 screwdriver, remove the
2 screws and remove the metal bracket.
Disconnect 2 cables from the motherboard and
the camera module can be removed
from the iPhone 11
Next, disconnect 2 more cables and remove
the Face-ID module.
Disconnect the cable from the motherboard
and remove one screw using a Phillips screwdriver.
Take a Standoff 1.5mm screwdriver and remove
3 screws on the motherboard.
Remove the metal panel and disconnect all
the cables from the iPhone 11 motherboard.
Now you can remove the motherboard from the
iPhone case.

What you need to know when replacing the motherboard
on iPhone 11.
If you need the iPhone with all working functions,
then you need to replace the Face-ID module
and the light sensor on display module together
with the motherboard, because all these parts
connected with each other from factory where
iPhone 11 was assembling.
But, if you do not need a Face-ID, you can
only change the motherboard.
In the description under the video, you will
find links where to buy the kit: a motherboard
with face-id module and sensor, or only a
motherboard.
Let's begin to installation motherboard in
iPhone 11.
Install the metal panel and place the board
in the iPhone case.
During assembly, I will answer your most frequently
asked questions.
The most popular question: if I replace the
motherboard on a locked iPhone, iCloud will
disappear or not.
Answer: Yes, when replacing the motherboard,
you get like a new iPhone 11 with a new serial
number and IMEI.
The next no less popular question: the new
motherboard will work with SIM card of my
country.
Answer: If you install an unlocked motherboard,
you can use the SIM card in the iPhone 11
of any operator, any country.
Next question about the quality of motherboards
that sold on Aliexpress.
Answer: The motherboards that sold on Aliexpress
can be restored after some kind of breakdown,
or unlocked if the iPhone 11 was previously
tied by contract to some mobile operator.
Personally, I bought motherboards on Aliexpress
4 times for different iPhone models and all
the motherboards were working, but this is
my personal experience, and I do not urge
anyone to buy motherboards on Aliexpress,
I just share information where you can buy
spare parts.
Last question: Are motherboards on Aliexpress
original?
Answer: Yes, the original, but restored or
it's unlocked.
Well, the iPhone 11 assembled and now you
can connect the display and check how the
smartphone works.
To test the iPhone, just connect three display
cables and then the battery cable.
Turn the display over and turn on the iPhone.
Check how the display works, and also check
the Face ID and the ear speaker.
After replacing the display, True Tone will
not work.
How to restore the True Tone function; watch
in another video, link in the description
or at the end of the video.
Check how the camera works.
Check all function of the iPhone and
If everything works fine, you can begin to
the final stage of the iPhone 11 assembly
with restoration of water protection.
Remove the old silicone tape from the case.
Using isopropyl alcohol and a cotton swab,
you can wipe the case.
This is not necessary, but definitely will
not be superfluous.
Now take a waterproof adhesive tape.
That tape restore protection of water and
dust on your iPhone 11.
Before applying adhesive tape, make sure that
you stick it on the right position.
Press on the tape around the edges.
That need for sticking to 
the back housing.
Now begin to the installation of the display.
Connect 3 cables of the display module to
the main board and only after that, connect
the battery cable.
Install small metal panel and fasten the 3
screws.
One of the screws is located very close to
the display cable, so fasten it carefully.
Now install the second panel and fasten the
5 screws.
Turn the display over and press it around.
Fasten the last 2 screws near the charging
port and you can turn on your iPhone 11
So, I hope this video was useful for you,
and I helped restore your iPhone 11
