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?

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.

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
I would like to know if it's possible to flash the firmware for
T-mobile I'm looking to leave verizon I know that the Verizon variant does not have 2 of the lte bands that T-mobile uses can I use Odin to Flash the 935t firmware to get the band's or am I asking something that is not possible. Thanks in advance

The answer is NO you're asking firmware to replace/add hardware and that's not possible
I have a Verizon branded s7 edge and used Odin to load the 935U PI3 firmware. I am on T-Mo now and do have LTE band 12 working (validated with LTE Discovery). The research that I did found that the US variants have all the radios in them, but some carrier variants of firmware disable certain bands. By doing the 935U firmware, I also got rid of the notice on every reboot that I was using a non-Verizon SIM. So I now have all T-mo bands and no stupid SIM message.

I can vouch for same experience as SF-IT guy. I bought a G935V and flashed with G935U firmware via odin. Works on T-mobile, even wifi calling works. Currently on the latest PI3 version of G935U firmware. I would that you search the forum to see if you can flash the G935T firmware directly. The only downside of using G935U firmware is that the FM radio chip is not enabled in the firmware. I read that the all the carrier versions (September security patch and newer) of the G935 firmware have the FM radio chip enabled. I prefer the 935U version because it there is not carrier bloatware. Samsung bloatware is still there.

So what would the FM radio chip do? Just enable FM radios is all? Because if that's the downside then it's not a major setback as not too many people use the FM radio.

You definitely can. All US versions of the S7 & S7 Edge are the same hardware and can be flashed to any other US firmware. (including the U firmware that automatically works on all 4 carriers)

So what you're saying is that flashing the U version firmware will unlock by default all 930"X" and 935"X" phones? As in it just unlocks the mofo and debloats some while you're at it?
What's the catch? It seems too easy

Bloat is definitely gone on the U firmware, which is great. My phone runs faster and has more free space too.
I think some carrier features aren't supported on the U firmware. On T-mobile everything works (VoLTE and Wi-Fi Calling), but I think AT&T might have some issues with those.
If the phone is SIM locked to a particular carrier, I'm not sure that automatically gets turned off or not when you switch to the U firmware. You might need to contact your carrier first to get an unlock code?

What if I got a temporary unlock from t-mobile unlock app and then flashed this firmware? Would it make it permanent? Seems quite possible, but I don't know if the temporary unlock actually unlocks the phone or just inserts a bypass that would disappear if flashed.

I unlocked my US TMo phone when stock, rooted, and am running Echoe - which has a glitch where WiFi calling sort of works (can receive calls but not make them). In the TMo forum, there are threads on U - your comments here are more specific to what I am interested.
Which U firmware are you on and are you rooted (is is updated to latest v4 bootloader version), and did you have to ODIN and full wipe with CSC or did you get by with CSC Home to preserve data?
Also, are you on U CP or did you flash TMo CP to get all the bands?.

I need to use VoLTE servie on my s7 edge G35U , but its not the option I am getting easily. I need to use the Jio4G service, but I dont have that option on my G935U (single sim) Global variant. I could have flashed the Indian INS firmware, but the issue is, indian version is Exyons veriant and the U one is running with the snapdragon, also the indian one is a G935FD (dusl sim). So, I cant flah the Indian firmware. So, what are all the avilable options for me to get the VoLTE working on my G935U ?
I have tried the T-Mobile (G935T), Version (G935V) frimware which support VoLTE for US carriers, but it wont work for Jio4G network.
So, the doubt is can I flash the U frimware with the Indian Firmwares CSC and check for the VoLTE support? will the exynos vartiants CSC (G935FD) works on snapdragon (G935U) ones?
Or is there any particular solution for getting VoLTE? Eagerly waiting for a resolution, please help me!.

Hey, I am also struck with the same.. I am using Jio4G service. Why could not you use that? I can help. Coming to the CSC, someone has to modify the 935U firmware CSC with INS/INU, until then we can not use it. I have tried to flash 935FD CSC along with other AP,PD etc of 935U through ODIN but it failed. ( T-Mobile and verizon firmware does not work as they had their respective CSC codes and also 935U has all US CSC codes)

Okay. While we awaiting someone's attention - let me run this thought by you.
Firstly, Im new to the android world, firmware, rooting, etc... However with the limited googling done, I wanted to check if this will work.
What if we root our phone and disable/uninstall the RCS application (in my case it would be TMobile) and then that will allow Jio to act as RCS App??

If you are having issues in using the Jio4GVoice Applicatiom. Just install the G935U Firmware so that both data and calls work. Though VoLTE is not there, the Jio4GVoice Application will work and also all bands are unlocked in G935U , you can also select specific bands of Jio. Only thing is VoLTE is missing in G935U , maybe someone can get that feature... hoping for best
I'm pretty sure you need to change CSC to your region. Give that a shot and post back your results. I know the SM-G935U can't flash kernels because it is boot-loader locked, but I'm sure you can flash system and csc via flashfire and odin. So tinker with it see what you come up with.

If you want 935T back again, flash the latest version of the 935T firmware. That's it, but even having the VoLTE on T doesn't help with Jio.
No solutions yet.. I am using jiovoice app for the time being..
You need hyour own carrier CSC file for VoLTE etc. But using your own CSC with the BTU nougat ROM breaks things, and cannot be used. You need to wait for your carrier to update.

It's not possible bro. U can only do this if u have exynos version bought in any country. U,T,A,P,V models have Snapdragon version.
When it is come to Samsung, They maintain regional settings in CSC file which has all these regional settings like volte, APN etc . These CSC file made for exynos won't work on Snapdragon.
I have tried many combinations earlier, flashing snapdragon firmware and Exynos CSC but doesn't workout. I have 935U earlier and tried all these and sold my phone.
We also can't Unlock bootloader for Snapdragon Version and Can't even achieved proper root. SO Volte is not possible.

You cannot update via OTA when changing to a different firmware unless it is EVR firmware. If you flash CSC then you can get OTA updates.
The only way to retain the EE Wifi calling is to remain on EVR firmware.

I have recently flashed the BTU Nougat firmware and can confirm that I am able to use WiFi calling on EE
Flash AP, CP, BL & CSC (or CSC_HOME if you want to retain data but may cause some issues)
Wonderful, thanks for confirming. I've downloaded BTU 7.0 and EVR 6.0.1 from sammobile so I guess my steps are:
1. Full backup of my S7 Edge (EVR 6.0.1) with Smart Switch
2. Remove SD card
3. Flash BTU with BL, AP, CP and CSC
4. Full reset/erase
5. Test WiFi calling, presume it's in the dialler settings still
6. Restore data/apps with Smart Switch
7. Check for any OS/App updates
8. Have a cider
Sound good?
BTW, when I last had a go at flashing BTU 7, there was no WiFi calling in the dialler settings Hopefully it'll work this time and at some point, EE will allow VoLTE (if IMS doesn't keep falling over).
Cheers
I can't find any WiFi calling options in settings on BTU 7 which I flashed over my EVR.
Interesting, that is why I'm reluctant to do it again. I've heard it work for some and others say flash with BTU 6.0.1 and then OTA to 7.0
Not that WiFi calling matters again now as EE have yet another IMS issue, no WiFi calling or VoLTE ....... AGAIN!

What is this IMS issue you're talking about?
Anyways, I've had VoLTE working since the Nougat ODIN files became available.
Flash official Nougat files + BETA 1 CSC (Nougat OXA) and Wi-Fi Calling and VoLTE works fine.
The IMS (IP Multimedia Subsystem) is the tech stack that allows for VoLTE and WiFi calling over 4G.
Regarding your method of retaining VoLTE/WiFi calling, I like it. Where can I download the beta firmware from in terms of a reputable site?
Incidentally, do you know which beta version stopped VoLTE on EE?

Wonderful, thanks for confirming. I've downloaded BTU 7.0 and EVR 6.0.1 from sammobile so I guess my steps are:
1. Full backup of my S7 Edge (EVR 6.0.1) with Smart Switch
2. Remove SD card
3. Flash BTU with BL, AP, CP and CSC
4. Full reset/erase
5. Test WiFi calling, presume it's in the dialler settings still
6. Restore data/apps with Smart Switch
7. Check for any OS/App updates
8. Have a cider

Sounds good, but I'd change step 8 to a lager!

I flashed the latest official BTU firmware with Odin and have been using WiFi calling for 24 hours without a hitch.
The firmware can be downloaded HERE
