Fix for VOLTE Marshmallow MIUI

Last night one of my friend told me about this. So i tried and found it working. All credits to him to discover this, i am just sharing.

Things required:
1. Redmi note 3 with bootloader unlock and TWRP recovery
2. Any Marshmallow MIUI rom
3. Firmware zip

Steps:
1. Unlock bootloader officially/unofficially and flash twrp by fastboot.
2. Download the firmware zip and rom and place them in internal/external sd.
3. Flash the firmware zip first and then the rom.
4. Reboot.
