How to Enable VOLTE on custom ROM? - Samsung Galaxy S7 Questions and Answers

My phone is S7 Singapore version (G930FD, the CSC is XSP/OLB). Before I installed custom ROM, VOLTE is working fine. After I flashed the custom ROM, I found there is no option for VOLTE and the CSC is DBT or INU and cannot use VOLTE.
So, is it possible to add the OLB CSC or XSP CSC back to the custom ROM that allow it to support VOLTE? Or is there any other ways to enable VOLTE? Thanks.

I still would like to thank you for replying. However, it does not work for me as my CSC here required is OLB, that is not listed in that tool.
So, I am trying to work in the other way. Is it possible to extract the CSC from my official ROM first, and then flash it into another custom ROM?

Well depends
If your carrier offers specifics features like VoLte or wifi calling and the CSC you use do not...then you will not have them
Also you will have the installed CSC OTA´s not your country carrier OTA
Other than that the phone will work just fine

BTU is there now..
Does anyone have a mega link? I'm cheap and only have free access to sammobile :fingers-crossed:
Which odin are people using to flash firmwares.
Warning
OFFICIAL STOCK Firmware-update (Odin) thread Samsung GALAXY S8+ SM-G955F
Be advised, that BTU is now part of the Multi-CSC OXM
OXM has a lot of CSC's included! If you want to change i.e. fm Vodafone-firmware to BTU, the possibility is very high you won't get the BTU CSC but the 1st CSC in the package of OXM, which is AFR
I use Odin 3.12.3

Did you download the BTU from sammobile and flash as per the secure pin instructions? Is it luck that you got XEU from the flash or likely to do the same on my Vodafone model also? Thanks.

I didn't follow the secure pin instructions. I used the program SamFirm and downloaded the BTU rom which had the Multi-CSC, my firmware was Vodafone branded and had the Vodafone VOD CSC.
Once I used the correct Odin and flashed the BTU rom I reset the phone in the settings and then I had the XEU CSC which is the correct CSC for Ireland and the UK.

Use Odin 3.12.3 and CSC_OXM (NOT HOME_CSC_OXM)
Your device will be resetted afterwards...

Thank you. I flashed and now have build number NRD90M.G955FXXU1AQDD
Service provider software XEU/XEU/VOD
Is this UK/IRL XEU or still Vodafone UK firmware?
Excuse my ignorance, what is BTU? I am with O2, what benefit do we get from flashing BTU, no bloat apps?
Also I haven't yet accepted any updates, if we do, and realize for example we want to Re-map the Bixby button can we backtrack with this Firmware?

Hi
Are rooted and have a custom recovery?
you have a G935W8 which makes it a little more difficult.. but not imposible
You are already rooted ..you need a custom recovery (TWRP)
then you flash this utility:
https://forum.xda-developers.com/s7-edge/development/utility-flashable-csc-selection-30-t3392957
And select INS Indian multi csc , now you have the correct CSC
But to make work VoLTE with JIO you need another app
https://www.jio.com/en-in/apps/jio-4g-voice
You need both to make it work

Hi
to your questions:
Yes , Indian CSC can be add to your Canadian Stock Firmware
As far as I know the only way to use VoLTE in India is thru that app , anyhow better check locally
Even both firmware are basically the same ( F and W8 ) you can not flash directly in your device the F version , you could flash a Custom rom like SuperStock

Yes , Indian CSC can be add to your Canadian Stock Firmware With the CSC utility , from recovery , as is explained in the thread I point out
Even both firmware are basically the same ( F and W8 ) you can not flash directly in your device the F version , you could flash a Custom rom like SuperStock I made this comment for that purpose, even they are probably the same firmware their "signature" is different therefore it cant be flashed with Odin

Switching Firmware on Galaxy S8+

Today I tried switching my s8+ which is an Italian unlocked model (ITV) to a United Kingdom unlocked firmware (BTU). I followed all the steps as this is not my first time flashing firmwares with Odin. I found a thread online saying that since BTU is a multi CSC , I need to flash a ROM that's is outside the multi CSC , so I decided to flash a O2 ROM , straight after flashing the BTU hoping that it would change the CSC , but it didn't instead it stood on ITV, the country/region is still on Italy too. Can anyone explain what I done wrong pls ?
Why do you even care about csc ? Install rom for your coutry "global", not branded soft and that's all...
BTU is not branded, it's unlocked with no carrier. Updates are also provided directly from Samsung. I would like to change the ROM for faster updates and features

So according to what I read it's impossible to change the CSC to BTU on the Galaxy s8 unless you have a UK Sim. This used to be possible on the s7.

But NOT possible anymore on the S8/S8+
ITV & BTU are both part in OXM. When you flash BTU-ROM, your device will stay ITV because both are in OXM...

Yes, S7 didn't use the multi-CSC, each region had it's own CSC.
But the Euro S8 has Multi-CSC, so it won't change region until you put in a SIM from that new region.
Thanks guys for helping. I just wanted to change the CSC for quicker updates and for region specific features like Bixby Voice when it gets released in the UK.

Help! Need to change the CSC for S7 SM-G930T

Hi,
I have an unlocked Samsung Galaxy S7 from T-Mobile (SM-G930T). I wanted to use this phone in India with Jio as the service provider. Jio is a 4G only provider with VoLTE. Unforturnately with my S7, VoLTE does not work due to CSC of my phone being TMB. Jio supports VoLTE for phones with INS as CSC. The 4G data does work with the phone. I am hoping that it is possible to change the CSC for my phone. Please help.
Thanks in advance.

Hi,
I have a Samsung s7 930T as well. I want to update to Oreo 8.0. Have found the firmware on SAMmobile. Does any one know if my sm-g930T will accept the g930f update? I assume I'll need to flash the bl, ap and all that to change csc. WIll that be included in the firmware down load? Do I just flash all that with ODIN?
Thanks!
