Welcome to HowFixit and in this video, I will show how to replace motherboard on the iPhone 11 Pro
What tools you will needed to disassemble
the iPhone 11 Pro: Screwdriver set
Plastic mediator Suction cup for removing display
Tweezers Plastic opening tool
Adhesive tape for restore water protection In the description under the video, you will
find links where to buy all these tools and replacement parts for iPhone 11 Pro
Turn off the iPhone, then near the charging port, remove 2 screws with a 0.8 mm Pentalobe
screwdriver
Next, take a hairdryer and heat up the display surface.
The required heating temperature is 60-70 degrees Celsius, the maximum is 80 degrees.
Fix the suction cup on the bottom of the display, then take a thin plastic mediator.
Pull the suction cup ring up and begin to disconnect the display from the iPhone case.
Open the iPhone 11 Pro by turning the display to the right side, like a book.
Hold the display or place something behind the display.
Then remove the 2 screws on the small panel and the 6 screws on the large panel.
First disconnect the battery cable, after 3 cables from the display.
Let's move on to replacing the motherboard on the iPhone 11 Pro.
This is a quick repair process, and first, disconnect all the cables from the motherboard.
Remove the 4 screws and remove the metal panel.
I recommend removing this panel so as not to break the camera cables when removing the
motherboard.
Remove the 3 screws with a 1.5 mm Standoff screwdriver.
Now you can remove the SIM card tray and push the SIM card eject piston back into the housing.
All that remains is to get the motherboard out of the case, but be careful with the cables,
do not bend them much.
What you need to know when replacing the motherboard on the iPhone 11 Pro.
If you need all working functions on iPhone, then you need to replace the Face-ID module
with the motherboard, as well as the light sensor on display module, because all these
three parts are connected to each other from the factory where the iPhone 11 Pro has been
assembled.
But, if you do not need the Face-ID function, then you can only change the motherboard.
In the description under the video, I leave links where you can buy the kit: a motherboard
with a Face-ID module and an light sensor, or just a motherboard.
Now you can move on to assembling.
Install the motherboard into the case and fasten the 3 screws with a 1.5 mm Standoff
screwdriver.
Connect all the cables to the motherboard and install the metal panel on the camera
module.
Fasten all screws on the metal panel.
Insert a SIM card and you can begin to check your iPhone 11 Pro
To test the iPhone 11 Pro, just connect 3 cables from the display and after the battery
cable.
Turn the display over and turn on the iPhone 11 pro
Make sure the smartphone is working correctly, check all the functions, and if everything
works fine, you can begin to the final assembly with restoration of protection against water
and dust.
Remove the silicone tape from the case of iPhone 11 Pro.
Now you can wipe the case with isopropyl alcohol, this is not necessary, but it certainly will
not be superfluous.
Take a adhesive waterproof tape, but before stick it on the iPhone case, make sure to
glue it with the right position on the case.
This silicone adhesive tape restores protection against water and dust, but it doesn't provide
100% protection for your smartphone from water.
Press the sticker down so it sticks better to the case.
If you don’t have such a sticker, in the description under the video you will find
a link where to buy it.
Now let's connect the display module.
First connect 3 display cables to the mainboard and only then connect the battery cable.
Install the panels and fasten all the screws.
Turn the display over and push it to the iPhone case.
It remains to fasten 2 screws near the lightning port, and you can turn on your smartphone.
I hope this video was useful for you, and I helped restore your iPhone 11 Pro
