S7 Edge binary 8 INS firmware

[Samsung_itFaxMy]

Hi, I have an SM-G35FD, and flashed the UAE firmware (XSG), which is binary 8. 

After that VoLTE stopped working, and I can't roll back because Indian firmware (INS) is only available in binary 7. This has made Jio unusable.

Odin wont let you flash to a lower binary, so I'm stuck. Any idea if someone can help me find INS binary 8 or higher so I can get VoLTE and VoWIFI back?

Thanks guys

try changing your CSC

*#272*IMEINUMBER#-
input your IMEINUMBER.

once this is done if you see CSC list of Countries select INS and reboot your device.

you need to do this steps with indian sim inserted in the device.
Hopefully your 4G may start working.

The menu looks like below
