[FIX] No mobile network in Redmi note 3. IMEI Erased. How to fix IMEI on Redmi Note 3 Snapdragon variant. [RN3][KENZO][Snapdragon]

Some Wrong methods of flashing ROMs or sometimes theROMs itself, can lead to erasing of your device's IMEI number which can lead to Network connection problem. Even if you have your sim card inserted, you cant use mobile networks. In Redmi Note 3, It's not a big issue unless you have your IMEI number with you. There's this tool with which you can easily restore your IMEI back.

Credits to this tool entirely goes to 'this xda thread' where I found this information. I'm just trying to explain the steps in my own way.

What you'll need?

A Redmi Note 3. (Snapdragon variant only! If You are owning a mediatek device, this post isnt for you).
FastbootPackage - Download it here.
IMEI writing tool - Download it here.
A USB cable for connecting the device.
Make sure all the device related drivers are installed properly (read 'this article' to setup Fastboot/ADB drivers if you face any problem).

Compulsory:

To perform this step, you compulsorily need to be on any ROM, If you dont have any ROM installed because of any problem with MiFlash or something, This ROM which can be fasted directly while in fastboot, is for help.

Read this article on 'AOSP MM Factory fastboot ROM for Redmi Note 3 Kenzo'

If you are already on any ROM already, continue below.

Procedure to Restore IMEI:

Step 1: Connect your device through USB cable. Make sure your computer detected your device.

Step 2: Extract the 'FastbootPackage' archive which you downloaded. You will find a file 'cmd.exe'. Run it with administrative rights.

Step 3: Make sure you have enabled USB debugging in your phone.

Enable USB debugging in phone:

Step 3.1: If you have already enabled Developer option before, go to step 3.

Step 3.2: Go to Settings > About Phone > Tap 'Build version/MIUI version' 7 times simultaneously until you have Enabled developer options.

Step 3.3: Go to Settings > Developer option > 'Enable USB debugging' . (in MIUI roms, Settings > Advanced settings > Developer option > 'Enable USB debugging')

Step 4: Now type the following command in the cmd.exe you just opened. This will establish a connection to your device's terminal.

adb shell

Step 5: Next, Enter this command to enter diagnostic mode.

setprop sys.usb.config diag,adb

Step 6: You are now in Diagnostic mode. Now open the IMEI fix tool which can be found in 'IMEIfixKenzo' package.

Step 7: You must see something like 'COM' in the toolkit. (If you cant find it, your device wasn't properly connected. Try retrying the above steps again).

Step 8: Now Type the IMEI numbers (both slot 1 and 2) of your Device. Which can be found in the Device's factory package box. See image below.

Step 9: Make sure you have entered your correct IMEI numbers.

Step 10: Click on 'Start'. It will take a millisecond to write IMEI. If successful, it will show 'PASS'.

Step 11: That's it. Now you need to reboot to see the effect taken place.
