It is not EFS issue...
It is all because of different Modem issue.. all you need to do is just install a clean Stock ROM from Sammobies firmwares and Install the patched modem... you are done..

So here is the solution:
1. Download your desired Stock ROM for your Country from Sammobile...
Link sammobiles firmwares
2. Install the ROM via Odin
3. Root it and Install your favorite recovery.
4. Install the Patched MG4 Modem Zip in Recovery Mode.

You are done....
This problem is all about MODEM version, so I don't think if EFS tricks are involved here.....
