Turn off your iPhone before starting disassembly.
Remove the 2 screws near the lightning port with a 0.8mm Pentalobe screwdriver.
Take a hair dryer and heat the display surface for 1-2 minutes at a temperature of 60-70
degrees Celsius.
Fix the suction cup on the bottom of the display and pull the ring up until there is a gap
between the display and the housing.
Insert mediator and disconnect the display from the iPhone case on all sides.
At the top of the iPhone, do not push the mediator much into the case, so as
not to damage the elements from the face id module.
The case opens like a book - the display to the right.
Remove the 2 screws on the small panel and 6 screws on the large panel.
First, disconnect the battery cable and after 3 cables of the display.
Replacing the
motherboard in the iPhone 11 Pro Max takes about 15 minutes and this repair doesn't require
any technical experience, but there is a certain condition when replacing the motherboard,
so I recommend to watch the disassembly process.
Remove the metal panel and disconnect all the cables from the motherboard.
Remove the 3 screws on the motherboard with a 1.5mm Standoff screwdriver.
Remove the SIM card tray and slide the SIM card eject piston back into the housing.
Now, gently remove the iPhone 11 Pro Max motherboard out of the housing.
What you need to know when replacing the motherboard on the iPhone 11 Pro Max.
If you need the Face ID function on your iPhone, then with the motherboard you also need to
replace the Face ID module and the light sensor, which located on the display module, because
all these parts connected.
But, if you do not need to unlock the iPhone using the face recognition, then you can replace
only the motherboard and leave the old module and sensor.
In the description I left a link where you can buy a kit: a motherboard with a face id
module and a sensor, or only one motherboard.
You can install a new motherboard of any amount of memory, for example, you had an iPhone
11 Pro Max with a memory capacity of 64gb, you can replace it on new motherboard with
a capacity of 256gb or 512gb.
If iCloud is locked on your iPhone 11 Pro Max, for example, you forgot your password
and cannot recover it, in this case replacing the motherboard it give you like
a new iPhone 11 Pro Max.
The iPhone assembled and now you can check how the motherboard works before final assembly.
To check the iPhone, just connect 3 display cables and a battery cable, but only in that
order, first the display cables.
Check how iPhone works and if all the functions work fine, you can begin to the final assembly
of the iPhone with the restoration protect against water and dust.
Remove the silicone adhesive tape from the iPhone back housing.
Using isopropyl alcohol and a cotton swab, you can wipe the back housing, this is not
necessary, but it will not be superfluous.
Before attaching a new adhesive tape, make sure that you glue the right side on the back
housing.
This silicone tape restore resistance to water and dust.
This doesn't provide 100% waterproof for your iPhone but without this sticker, the display
will not hold well and dust will get inside the iPhone.
In the description you will find a link where to buy such
a sticker.
Press the sticker on top, so it sticks better to the case.
Let's begin to connect the display.
First, connect 3 cables of the display, then the battery cable, and only in this order.
Install the panels and fasten the screws.
Turn the display over and push it to the case.
Fasten the 2 screws near the lightning port and you can turn on iPhone 11 Pro Max.
That's all, I hope this video was useful for you and I helped restore your iPhone 11 Pro Max
