Hello everybody! Welcome once again to a new video
We're actually making a basic course where we're
introducing concepts and the measurements to everyone who's starting in the world of microsoldering
Remember, we're going step by step
in this moment we're seeing a bit of some of the tools that we're going to use
but eventually we'll be starting to measure components, what kind of components we're going to use and that stuff
Today, I want to talk about the NAND programmers
What is a NAND programmer?
if you already know what it is, this is not a lesson to learn how to use it
It's a lesson to know what it is and what uses we can give to it
much more than just know how to use it, because we're going to see more about it on the future NAND lesson, ok?
Once we get to the NAND lesson we'll be using it
For now, I want for everybody who's new in this
the NAND programmer
will be used to program the storage memory of the iPhone
what does it means by "storage memory"?
every iPhone has a memory
where it is the software, the client's data and encrypted information
sometimes, those memories, cause they're hard disk drives
could get corrupted
therefore, when a new software is installed or the phone updates
it launches an error message on iTunes like error 413, error 4000, error 9
and some other errors related to the hard disk drive
in those cases, here enters the programmers
in my personal choice, I do use the JC programmers
there are a lot of programmers from different trademarks, some of them are cheaper
it's just, when I started to work on this, there were just a few of programmers
so I had to buy JC
JC it's a bit expensive
the problem with JC is, for example
if you need a programmer for iPhone 6 - 6 Plus
you'll need this
if you need it for iPhone 6S or 7, you'll have to buy this other one
if you need it for iPhone 8 - X, you'll need another one
and another one for iPhone XS onwards
you'll need to buy another programmer, so
how do they work this programmers?
What they do is, format hard disk drive
and overwrite once again the phone's data
"What data are you talking about, Edgar?"
On the memory, the hard disk
there's a very important data, the Serial number, phone's model
the Wi-Fi version
the Wi-Fi address and the Bluetooth address
that means, the new phones from iPhone 6S onwards, it doesn't matter which one
just 6S onwards
we have to remove the NAND, the hard disk drive of the phone
unlock the Wi-Fi
how "unlock"?
For example, on the iPhone 6S, the Wi-Fi is encripted with the NAND
from 6S onwards, these two are linked
so what do we do with the programmers is, remove the NAND
decrypt the hard disk
in this case we unlock the NAND, it's also called Wi-Fi unlock
and now we can install any Wi-Fi
without these two being linked, so
we can use it for that, it can also be use to overwrite Serial Numbers
to change Serial Numbers or
change the Wi-Fi address
this is what people who unlocks iPad does
we don't use to do it
but it can be used it for that
or it can be used it to format the hard disk
so I can get it installed again
on the phone so I can install the software again without a problem
these devices over here, I'm going to change the camera
Like I told you, I do use the JC devices
this is the first one
this space here it's for the NAND
the NAND memory is this over here
like this one here, we need to desolder it
once desoldered, we put it in here
so, this one is for iPhone 6
then we have this one for iPhone 6S and iPhone 7
then we have this one for iPhone 8 and iPhone X
and lastly we have this one for iPhone XS onwards
there are many devices
I can remove this module here
and put them, here for example
like this
or I can use it via USB, connected to the computer like a software
here goes the NAND
and help us to format it or overwrite
Serial Numbers, Wi-Fi addresses
unlock the NAND when we need to fix the Wi-Fi of the phone
"Edgar, do we have to buy these programmers?" the answer is "Yes, you have"
probably not at the beginning, but if you make more
money, you'll need them, because
without them you can't fix the "Error 4013", "Error 9" or "Error 4005",
you can't fix any error related to the NAND
it's an advice
I'm only showing you some tools that you might need on this work
I didn't start with all of them
First I bought one and worked with it, later I bought another one
and like a year later I bought another one, I bought them eventually, bit by bit
This is like a race, a marathon, not a sprint
first of all, you need to
acquire the basic tools, like I said on the previous video of the Thermal Camera
Which are the basic tools?
The microscope, the hot air gun and the soldering station
These 3 tools are the basics, so
if you make more money and want to invest it on your business
you should invest it on getting a better microscope, a better hot air gun and a better soldering station
until you feel comfortable
once you feel comfortable, you can start investing on these kind of tools
as I told you, this lesson
it's just to introduce you everything that
is related to the tools that we're going to use
because, when I explain the measures, I'll be using these tools and you won't know what are they for, so
this is everything for today's video, I hope you liked it and found it useful, leave a like and I'll see your comments below
Hugs, bye!
