How to restore your IMEI in android phone

This one of the problem encounter after flashing any rom , modding and etc. Invalid IMEI or lost IMEI? I have four methods on how to restore it when you lost your IMEI. What is IMEI? What is the reason why we need to restore it? Simply, IMEI have a big rule in your android device you can't even text or call without it. Phone IMEI have unique 16 numbers made by manufacturer usually this numbers found in the back of the battery of your phone.
I also have tutorial on how to back up your IMEI you can proceed here.

Note: I'm not liable for any damage of your device. Do it at your own risk!

1. Using Manual. This are the simplest and easiest method. Using your phone only but not much more effective due to phone has different manufacturer and this method doesn't work in any other phone esp. updated SOC's. If not work just proceed in other method.

Note: Some phone doesn't  work this code *#*#84666364#*#* to go in engineering mode.
If nothing happens in code download MTK Engineering Mode in playstore then go Connectivity>Cds Information>Radio Information. Then proceed to step 3.
