I am looking to buy one of the international models with the Samsung CPU, but plan on using the phone on T-mobile's network and would really like to use wi-fi calling. Is it possible to use a rooted t-mobile ROM on this phone?

The issue with that is, the international variant is Exynos (which is better, may I add ) and I think the T-Mobile (USA) variant is Snapdragon.
Because of the architecture you probably can't use just use a T-Mobile stock ROM but there might be some sort of tweaking you can do to get it working. I am from the UK and my carrier is EE which supports WiFi calling, so you might be able to start with something like that.
If you root the phone, you can flash the tmobile csc from the universal csc file (get the note 7 csc if you use a n7 port). With it, I have WiFi calling, volte including video call.

CAN u provide link to the flashing of csc. Funny thing is that someone posted a sm935f on ebay and they mentioned that they messed up the csc flash. Is there a way to fix a messed up csc flash?

No guarantees this will work.
OK, I flashed my G935FD dual sim with G935FXXU1BPH6_G935FVFG1BPH1_VOD ( I did AP BL CP CSC), it rebooted did a couple of OTA updates, has wifi calling enable, but still wont wifi call, or go into wifi calling mode.
After the flash and OTA's I checked the versions and have :
AP G935FXXS1BPJ1
CP G935FXXU1BPHJ
CSC G935FVFG1BPH1
this is exactly the same as my UK Vod shop purchased G935 single sim, which obviously does go into wifi calling mode
One minor point, my G935FD dual sim phone receives messages dfrom VOD after a sim change stating auto configuration of APN is not possible, is VOD UK still detecting my dual sim device and disabling wifi calling
any ideas anyone pls, has anyone got WiFi Calling to work on 935FD for Vodafone?
cheers
(oh, also tried G935FXXS1BPJ1_G935FDBT1BPH2_DBT.zip and didnt even have the wifi calling check box )
I have mine working on the att version

cool, I have heard from other ATT or UK EE users who have made this work easily, just no vodafone users
update here from me :
Having tried many roms, with no success, I reverted back to a UK VOD ROM, as this was a multi CSC ROM, which defaulted to VOD2 CSC (Germany I think), I rooted the device and changed the CSC to VFG (VOD UK I believe)
Still no wifi calling, though it is enabled in the CSC and onmy account I dont have the check box under phone settings -and have no idea how to force it to appear.
Any ideas pls, has anyone successfully got WiFi Calling to work for Vodafone (UK ??) on a 935FD ?

I am interested in getting a dual sim version of the s7 edge to use with EE in the UK. Could you please elaborate on compatibility with EE's wifi calling? Did you read about it in some forum? Do you know people who have tried it? Do you know exactly which versions are compatible (935FD, 930 , etc)? Thanks!

So you flashed a single-sim firmware (for G935F) onto a dual sim phone (G935FD) and it worked? Did you retain dual sim functionality?

Yes flashing firmware for the G935F retains Dual SIM functionality, mine is flashed with the BTU firmware as UK s7 version
@copex , thanks! Are you on EE? Have you had a chance to verify if wifi calling works?
Also, is there any particular way to flash the firmware with Odin? Or shall I just follow one of the many guides on the web?
I don't need to be rooted, right? I don't want to root because otherwise I won't have access to my work email.

I am on EE but via Plusnet mobile and they do not support wifi calling, i used Odin to flash the device as i changed the CSC to BTU i done a full wipe so i could get OTA updates, i followed the info here.
https://forum.xda-developers.com/s7-edge/how-to/official-stock-firmware-update-odin-t3335065
i used SamFirm_v0.3.6 to download the uk firmware

What do you mean exactly when you say you changed the CSC? When you ran Odin, did you load all 4 files: BL, AP, CP, CSC ? Specifically, did you load the CSC file or the Home_CSC file in the CSC box?
Thanks a lot!
On a different note, where were you able to buy a dual sim s8?... all the ones on Amazon come with a clear "no Warranty" disclaimer.
I am not sure dual sim S8s are out yet - we were talking about the s7 edge. These dual sim phones can typically be bought in countries like the United Arab Emirates or Hong Kong, or on ebay, but if you buy from there and bring the phone to Europe or the US it basically means no warranty. There are also lots of small websites that sell them, but I wouldn't even consider them unless they support the paypal guarantee - who are you going to sue if they don't send you your phone?

when you download the BTU firmware there are two CSC files one will allow the phone to update and keep the data and the other will wipe the phone and you will lose all of your data, when you change the CSC region you have to do a full wipe to get OTA updates, if you upgrade the OTA updates will stop if the CSC region is changed
you have to flash all 4 files.
the csc file i flashed was CSC_BTU_G935FBTU..................................... if i remember correctly the CSC_HOME............... is the one that updates the phone
Hello, I would like to know if I can flash my verizon galaxy s8 with tmobile software, or any other model, since I can see that this year all the carriers are using the same model G950U. That is, a single model with different carriers, very similar to how the international version G950F works which is the same model for all carriers in Europe and allows you to change the software through ODIN. I hope someone can help me. Thank you very much.

From what I've gathered is that there's a user data partition that dictates the carrier and Odin currently doesn't allow flashing of this.
Saw this as a comment somewhere here and best I've seen so far.
Personally I think it is just a matter of time before we figure this phone out and will be able to do whatever we want. They already have root for Exynos model and I think now the search is on for modified Odin, as Tehpirate said. I believe they had modified Odin for S7, to do similar stuff, so it's not like starting from scratch.
I hope is the same like the s7 U firmware... That's nice cause I can flash U firmware and get rid of the carrier bloatware.
Hello is there a way to flash the T-Mobile (G950U) firmware onto a G950F model phone or change the CSC without root? While the phone is working, I do not believe it is able to take advantage of carrier aggregation and VoLTE without the proper region code for my area. Wondering if there is any way to achieve this? Thank you.
You want to flash snapdragon firmware on an exynos phone? You sure?
I'd like to know this too...
so is this not possible??
Guess I went the wrong route by purchasing an unlocked phone to use on the Tmobile network. the internet is sooooo slow...
I recently got a SM-G950W (galaxy S8 Canada) it was locked to rogers previously now the phone in factory unlocked with a code and I now have a Freedom mobile sim card inside
The phone works fine, but there is some bloatware from Fido that will not go away even after a factory reboot, and I want to ensure that I will be able to get Wi-Fi calling enabled for Freedom mobile.
I would prefer to have an unlocked firmware with no bloatware, but if that would prevent me from getting Wi-Fi calling I would rather just install Freedom mobiles firmware and take the bloat that comes with it.
I'm really a Noob at this and don't fully understand the difference between a AP, CSC or firmware. is firmware the same as CSC?
I just want the least bloated version that will get me the quickest updates and will receive all the features and frequency bands that my new carrier (freedom mobile - previously known as Wind Mobile) provides. How would I go about doing that?
When I run *#1234# I get these values
AP: G950LOU1AQEJ
CP: G950LOU1AQEJ
CSC: 950W0YA1AQEJ
Can someone help me out

Yes I saw that thread. Unfortunately its entirely about switching the US variants. I am looking for advice about switching the Canadian variant from a Canadian network to another Canadian network.
