Method 2

Few users had asked me how to change their IMEI number. Below is one such question from the users.

Hi. I searched all the websites for changing my IMEI to a correct imei ,because my IMEI was changed to fake 0049 and I can’t make calls and not registered on the network was showing. Is there any software that can change it? I need that software without IMEI BOX. My cellphone is galaxy NOTE 8 n5100

To Change your IMEI number is to back up the IMEI number.

Here is how to backup EFS or IMEI on your Galaxy device:

  • This process requires you to first download an app named as ‘EFS Pro’. But before that ensure your phone is rooted otherwise this tool will not work on the device.
  • Next download Microsoft.NET Framework 4.0 in your PC to make the EFS Pro app work on the PC. Once downloaded, unzip the file and install it on the PC.
  • Connect your device with the PC using a USB cable. Run EFS Pro and follow the onscreen instruction to backup and restore the EFS folder. That’s it and the process is completed.

Can’t afford another right now. Currently using a Lumia 900, which I despise. Also, the*#197328640# And the other only brings up service mode with no other options except under menu button. “End, Back, Key input, Select, Help”

Hope this helps all my fellow Samsung peeps
