An iPhone 11 Pro Max without IMEI
but they also wanted to increase the memory to 256GB
and that's what we're going to learn in this video
Hey guys! How are you? Edgar here welcoming you all, very happy, once again
with another video, this week will be full of videos
learning about everything
we must take advantage of everything we can
this repair as in other occasions, we're going to put it in fast motion, not so fast so we can
YOU'RE NOT SUBSCRIBED YET?
so that we can appreciate some details of the repair
this was an iPhone 11 Pro Max, it was pretty beat up
the problem it had was that it didn't show IMEI due to a crack inside
so we made a motherboard union, that's why it's very important to have
a CH5
to make work easier
motherboard union was regarding IMEI issue, now
something very important here is to increase memory, I talked about this with my students and told them
memory expansion is something we should not think about
literally we don't have to think about it, we just have to
remove the memory, reprogram it, take the other one, overwrite the data and put it back
it's something we don't have to think too much about
I've always said it, what makes a technician a good technician in this job is
is their reballing technique
and it's something I've always said, and it's a piece of advice that I give you
yes, you who are watching this video
the more hours you spend in front of your microscope
with your hot station, soldering, you'll improve
The more time you spend practicing reballing, the better your technique will be
So, this type of work is time-consuming
but
I didn't kill the phone because we have a good technique
because we have spent hours practicing
this is what I want to motivate you
this job is very well paid
this work that I did is very well paid
but if you don't have 2 things...
First, remember that we have to invest in tools
I need a programmer to do this job
there's the programmer
Second, have a good technique to do it
so
I didn't have to open a schematic
to check there, do a lot of things, no, you just need a good technique
"Edgar, what temperatures you used?"
Never use other people's temperatures
for example, I have air conditioning, I have to use more heat
you probably live in a hot area, you can't apply 380 ° to a NAND because the CPU could desolder
and things like that
always find your station calibration
in your area of ​​work, we will probably bring some interesting lessons later
that will help you to calibrate your hot station
so, let's make this repair in fast motion
so you can see the whole process, it wasn't that difficult
as I said, it's just the technique, a good reballing techinque to remove and place components
so, let's start with the video, let's play some music while I drink my coffee
Ok, as you could see
it was something very simple
I separed it and test it with iSocket
and saw it showed IMEI, with that I knew the IMEI failure was because the motherboard union
DONE, problem solved
Now I remove the NAND, it was a memory of 64GB
removed it
we removed one from an iPhone XS Max, because they're compatible with iPhone 11
we format it and then read the one from 11 Pro Max
copied that data and overwritten it in XS Max NAND
which was 256GB
then we installed that memory, restored the device
assembled the device, tested Wi-Fi, Bluetooth,
check that it recognizes Baseband version and IMEI
and everything worked just fine, as I said it was
easy to say how to do it, but difficult to put into practice
because we need to have a good reballing technique, but the most beautiful thing about this is
that you can improve your reballing technique as you like
You want to be good? Practice everyday
You want to be very very good?
Practice even more everyday
that's the only advice I can give you
So guys, it's a pleasure to always contribute to this community
we are growing a lot, and that makes me happy
don't forget to subscribe to the channel and leave your comments
"How's my reballing technique? How do I do my reballing?"
I'll be reading it, that gives me ideas for new videos
it was a pleasure to greet you all, take care, and we'll see you
in the next video
Cheers!
