In this video tutorial, I’ll be explaining how to backup and write QCN to a Qualcomm Android device

00:15
using infinity box CM 2 QLM module. You
need to have setup this dongle, we have a

00:20
guide on how to do that. You need to have
rooted the device. We have a guide for that

00:24
too. You need to have installed your Qualcomm drivers, we have a
guide for that. You also need to have boot

00:29
the device into Diagnostic mode, we have a guide on how to do that.

00:33
Now, once you’ve put all these in place,
what you’ll want to do is to install and

00:37
launch the Infinity box CM 2 Qualcomm
module. I’ll do that quickly. Then You’ll want

00:44
to (while the phone is on) connect the device to PC via the USB cord (while it is on)

00:50
don’t forget to enable USB debugging and
the phone should be in diagnostic mode

00:54
ok? Now, once the phone is in diagnostic mode, its going to look something like this in

00:58
your device manager, it’s going to have an entry like this. The phone should be powered on

01:04
and connected to the PC. It should look
something like this under device

01:07
manager. This is diagnostic mode ok? Good we have cm2 up. Now, what you’ll want to do is to click

01:14
on Read QCN. Just click this button. Don’t forget the phone should be

01:18
connected and powered on and then you
should have detection and this should

01:23
start backing up your QCN. Now, just in case you don’t know what the QCN does,

01:29
it’s your NV items. It contains your IMEI, Baseband, Wi-Fi & Bluetooth address

01:34
and all those things that involve the NV.
So if your QCN gets corrupted,

01:40
your phone won’t be able to detect your sim

01:44
network. So you might have issues like no signal on your phone, your

01:52
Bluetooth and Wi-Fi not working and all
those other NV related issues

01:56
ok? So that’s what the QCN is for. So this is ready backing up the phone’s QCN its very

02:02
important you do not interrupt the process and don’t forget that the reason why

02:08
your phone needs to be rooted is because
your phone needs to be rooted in order

02:12
to get it into diagnostic mode. That is the very reason why you need to

02:17
root the phone okay? Just to get it
into diagnostic

02:20
mode okay? Its only in diagnostic mode you can have this tool

02:27
being able to read or write QCN to the phone. Alright! Great! So QCN read

02:33
is complete. I have a done message in
this directory so what you’d want to do

02:39
is to check the directory, that’s my QCN file here. So QCN backup is

02:46
done. Now, if you want to write QCN, you’ll need to have the QCN backup of course

02:50
like I already did. All you need to do here is the same requirements, just click on Write

02:56
QCN this time around. Its the same requirement for reading just click on

03:01
Write QCN this time around. Make sure you have the QCN file. For this prompt, you can

03:05
click on yes, I don’t have any security
file or setting which I need

03:11
to supply for my QCN write. You just click
on yes to proceed. Now, a window will pop up

03:16
very soon. Good! in this Window, what you’ll want to do is to navigate to the location where your QCN

03:23
file is located. You highlight the file
and click on Open

03:26
and then that is going to load it as you
can see in the Chinese miracle II

03:31
Qualcomm module and QCN is being written to the device. Alright! Great! So that

03:37
is done. That’s how to read and write
QCN to a Qualcomm Android device using

03:44
infinity Chinese Miracle 2 Qualcomm module
