Is your APN settings set up for Jio? If not, try to change them manually.

Ok, too bad it didn't work.
Sorry ,I don't own the device myself so I'm afraid I can't be of any help in questions about downgrade. I don't know.
Hopefully someone else can answer.

Do you mean stock rom? I don't know about Q variant but i think it has kitkat 4.4.2. Go to sammobile and there you can find firmwares for your mobile.
Or you want to check another custom rom?

If the local carriers don't support VoLTE, nothing you do can allow you to use it.

Hi Chanchan,
The local carrier supports ONLY VoLTE hence making it imperative for me to enable VoLTE!! Any solutions??

Will that not brick the phone as Indian firmware is dual sim and on a different chipset...
Yes it will brick. Basically your only option is a new phone.

Don't flash BTU. Your phone will be bricked. As all International models are in exynos you can't flash an exynos Rom over snapdragon
Sent from my SM-G935F using Tapatalk
For VoLTE you need an Indian localized rom (for Samsung usually the local unbranded one works, too). Since in India the Exynos variant is distributed you will have a hard time to find a suitable rom for your Snapdragon one. If your provider does not have any app based solution you may be out of luck.
Volte mobile is good i love all features and speed of this phone. I like its work fast and did not hung.

I was in the same boat... Just flashed a U firmware over USA model and rooted it.
Then via flashfire, Flash this CSC Which was basically pulled out from S8 CSC selector file by @Tkkg1994
VoLTE should pop-up after reboot.
Even wifi calling toggle comes up but Jio is yet to implement the feature (Don't turn it on... you'll miss calls when on wifi)
Thank the original developers.

Why can't you root? You can't use this CSC via Odin.. it's a flashable zip.
I have an unlocked S8(GM-950u1) and I don't have VOLTE option. So if I want to have volte as an option, can I flash my phone to (GM-950FD)? If no, which firmware should I flash such that I get VOLTE as an option?

You might be able to flash your carriers csc and it may be enabled then. Thus turning the device into a 950u. But any f is a exynos edition and cannot be in anyway flashed to a u device

Does TMobile support VoLTE? If it does You can try TMobile firmware which would have VoLTE enabled in the csc files

You can't trip know on a US snap dragon device. All the csc is. Is carrier information and settings....
I can't say you can't trip Knox but in our everyday flashing. Even being rooted we cannot trip Knox.
