* This tutorial applies to only original Samsung phones.

An unknown Baseband is as a result of a corrupted EFS partition. The EFS holds the phone's IMEI and other radio information. To check the phone's Baseband, navigate to Settings > About > Baseband. Check the IMEI by dialing *#06#

You'll usually know you've been hit by the NULL IMEI / Unknown Baseband when you observe:

* Bluetooth address is unavailable
* WIFI connection will work inconsistent
* Constantly rebooting
* Fake IMEI  or Null IMEI # (normally - 004999010640000)
* Null Serial number -(0000000)
* Unable to register to network

When you encounter an unknown Baseband and NULL IMEI, the first thing you need to fix is the unknown Baseband by flashing the Stock ROM / firmware for the exact phone model using Odin @ https://forum.hovatek.com/thread-519.html
Once that is done, you can then write an IMEI to the phone

Method 2: Xposed IMEI changer

* Download Xposed installer @ http://repo.xposed.info/module/de.robv.a....installer and install it
* Launch the installer

* If you get "The latest version of Xposed is currently not active. Did you install the framework and Reboot" then follow the guide @ https://forum.hovatek.com/thread-7229.html to fix it
* Download Xposed IMEI Changer @ https://play.google.com/store/apps/detai...nger&hl=en and install it
* Launch the app

* Input your preferred IMEI and select Apply

* Reboot the phone

I can't enter service mode by inputting that code into the dialer! I have a Samsung galaxy s4 m919 running CyanogenMod 11. Could that be the reason why? If so any suggestions?

I don't have another working model of the device and I don't have access to a computer at the moment. But I will try the odin method as soon as I do.

The download for the fixed IMEI number for the odin method says for S4 GT i9500. Will it also work for an S4 M919?

What would happen if it doesn't work? Would my phone be bricked?

There's always that risk when flashing files to your phone
