Qualcomm Based Devices IMEI Repair by QCN File Value Edited.

[MiRoOo]

Ok, Here's another way for IMEI repair that works when your Baseband is good, but you still have IMEI:null or IMEI:0,
we're going to write a QCN file which contains an IMEI that's different from yours for sure,
So, as long as this process is a little hard for some ppl, if you decide to just write the file and forget about your original IMEI, then skip to the write part of guide,
Otherwise, follow the whole guide, and i promise to make it easy as i can,

Let's begin,

All the tools and files you need for this process included in this zip


<\GUIDE/>
----------------

#1 Edit QCN
------------------------
In this part we will edit the QCN file and replace it's IMEIs with ours,

1. Install HEX Editor which is included in the zip,
2. Open "y625.qcn" file with HEX Editor,
3. Find these addresses:
IMEI_1: 00001790


IMEI_2: 0000e490 + 0000e4a0

Now we know where IMEIs live in our QCN,
It's time to replace it with our IMEIs.

3. Run "IMEI_Converter.exe"
4. Write your IMEI_1 in the "ENTER IMEI" area then Hit "< CONVERT IMEI >",

5. Do the same for IMEI_2 ,

Copy the converted values and keep it in a txt file.

6. Now just go back to HEX Editor and replace the values with the new ones,
IMEI_1


IMEI_2


7. Now we need to save the file with the new changes,


Now we have a QCN file which contains our original IMEIs,
Great, let's move to the next part.


#2 Enable DIAG Mode
---------------------------------------
In order to Backup or Restore QCN, phone needs to enter a special mode called "DIAG",
Huawei like many other manufacturers disabled that mode by default,
But that's not a problem at all since we can simply activate it by adb shell commands,
Let's see how,

1. ROOT the phone using iRoot or any other root tool,
2. Connect phone to PC then run these commands one by one,

adb shell
su
setprop sys.usb.config diag,adb

3. Now check your "Device Manager", under "Ports" you should see this



Now you've successfully activated "DIAG" mode, and your phone is ready for QCN Restore part.


#3 Restore QCN
-----------------------------
This is where we write the QCN file to the phone using QPST,
QPST is an official tool made by Qualcomm itself and they are using it to deal with their phones and modems as it has a lot of functions,
One of it's functions the QCN Backup and Restore, which we're going to use here,

1. Install QPST which is included in the zip,
2. Run "QPST Configuration",
You'd see something like this,


This means that QPST has successfully see your "DIAG" port and can communicate with your phone.

3. From the menu, go to "Start Client" and select "Software Download",



4. From the tabs choose "Restore", click "Browse" and choose your QCN file,
Hit "Start",



5. When "Restore" process finish, Just reboot your phone,
6. Check your IMEI, it should be there,


<\DONE/>
----------

This guide is not about Y625 only, this is how to deal with QCN for most Qualcomm based devices not only phones,
I hope that i made myself useful to some of you by this guide,

<\BEST REGARDS/>
