Hi everyone, welcome to How-Fixit.
In this video I'll show you how to replace the cracked display on the iPhone XS Max and
save True Tone on new screen.
For repair You will need a new display module for the iPhone XS Max
Screwdriver set Plastic mediator
Plastic opening tool Tweezers
Suction cup for removing display Adhesive tape for restore water protection
And one more very important auxiliary tool, without which I do not begin any repair, is
a magnetic mat.
In the iPhone XS Max a lot of screws and they are different sizes and it is very important
not to confuse them in reassembling process.
In the description under the video, you will find links where to buy new display and all
these tools for repair the iPhone XS Max.
Disassembling Turn off the iPhone and remove the 2 screws
near the lightning port.
In my case, the screen is so broken and because of this, the suction cup cannot fix fine on
the surface of the screen.
To solve this problem, you need just tape.
So, this should be enough to secure the suction cup.
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.
Take a plastic mediator and begin to disconnect the display from the case.
At the top of the phone case, do not push plastic mediator into the case too much, so
as not to damage the Face ID module.
First you need to disconnect the battery cable and then disconnect the 3 cables of the display.
Next step is reinstalling the speaker with sensors.
This process is not complicated, but it requires attention.
Now a very important step, you need carefully detach the sensors from the display.
Before removing, I recommend warming up the cable surface with a hair dryer.
Take a thin, but not sharp tool, it is the best a plastic one, and begin peeling off
the cable from the bottom.
The light sensor is the part of Face ID system, so you need to very carefully remove it.
If this sensor damage, the Face ID system will not work.
That's it, the cable is removed and now it can be reinstalled on a new display.
In the description under the video you will find a link where to buy a new display for
the iPhone XS Max.
The display module is assembled, now I will connect the display and test it.
To test the iPhone, just connect three display cables and then the battery cable.
Turn the display over and turn on the iPhone.
Test the Face ID module, speaker, and the new screen.
As you can see, there is no True Tone toggle below the lighting slider.
This is because the new display does not have the native factory firmware from this iPhone.
Now I will fix this, turn off the display again.
To restore True Tone function, you need a programmer to transfer the firmware from the
old display to the new one.
The process of transferring the firmware is very simple, connect the broken display, read
the firmware from it and transfer this data to the new display.
That's all, the firmware has been transferred and now we can check.
I will leave a link to this programmer in the description under the video.
As you can see, now True Tone is available on the new display.
For example, If do not transfer the firmware, you will lose the True Tone function, which
gives a softer yellowish tone.
As you can see, if True Tone function turned off, the display shines in a bluer-colder
tone.
If this function is not important to you, you may not transfer the firmware.
If everything works fine, you can begin to the final stage of assembly iPhone with restoration
of water protection.
Remove the old silicone tape from the case.
Wipe the case using isopropyl alcohol and cotton swab.
Now take a waterproof adhesive tape.
That tape restore protection of water and dust on your iPhone XS Max.
Before applying adhesive tape, make sure that you stick it on the right position.
Press on the tape around the edges for better 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.
Fasten the last 2 screws near the charging port and you can turn on your iPhone
OK, the iPhone XS Max is assembled and working correctly.
So, I hope this video was useful for you, and I helped restore your iPhone.
See you on HowFixit.
