1. Your phone should be rooted
2. Open that app you installed and look for "backup imei"
App backup your phone's imei.And after that, when your imei nulled, root your phone if it isn't, install that app again and look for "restore imei"
And don't delete any folder named "5irom" or similar.It contains 3 img files.They are important.
