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)

Yes, I am currently using the Jio4GVoice app, but still it's not stable to work flawlessly... also the device is supported but.. without proper software it's not working. So, I hope someone has a solution or any developer could help us with this. What to do?... How to modify the CSC to work with this U device.

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.

@kiranhdg - I flashed my phone with 935U and I am able to use the Jio App, cannot make calls or Text via the regular dialer. Now, If i wanna get back on the 935T which did have the VoLTE, do i just flash the it with that firmware, or I can never revert the phone?? Thanks for your help though!!
download the tmobile firmware and flash it back. No big deal.

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.

Do you still have device? Please let me know. I have one work around to get VOLTE on my device
We can try same on S7.
Are there any custom ROMs (and CSC files) that allow the S8 to successfully have WiFi Calling and VoLTE on the AT&T network??
I am running RENOVATE ICE 3.0 but you need the Notorious Kernel 1.9 for Volte to work on T. Some kernels do not support Volte, but Notorious does. You also need to flash ATT from the Flashable CSC Selection V1.0.0, and create/edit the /efs/imei/mps_code.dat and put ATT in there. You can also delete the /system/omc/ATT/res directory to get rid of the annoying T jingle and boot screen. You then need to call ATT and ask the friendly customer service person to update your IMEI. But when you give them your current IMEI, they will not be able to find it since it is not a ATT phone. So they will use the IMEI of a similar phone. That will get Volte to work. But WiFi will not as I think the IMEI must match exactly in their system for WiFi to work.
Hello. I'm also trying to figure out the same. How can I unlock the G955U? is that even possible?
Ideally I'd like to get the CSC Patch installed so I can get WiFi Calling on ATT, as I do not have any reception in my area. Any Help here would be appreciated.
Can anyone help here? Thanks.

You can flash csc seletcion after the rom.
That package contains the csc of att and the US generic. That generic is the one that I use and it works volte, wifi calling in tmobile ...
Hi Eddie, would you happen to know how to Root the G955U? its the Unlocked version of the phone. I've followed every step for CF-Auto-Root through Odin, but it fails every time. It seems like the Bootloader is locked? Any help would be appreciated here.

If you mean network unlock, then follow the ToS on AT&T mobile and eventually you will be allowed to unlock your phone. And for you to switch from the firmware of SM-G955U to SM-G955U1, you gotta go to this forum: https://forum.xda-developers.com/galaxy-s8/how-to/rd-carrier-switch-root-snapdragon-t3597473
You will not get wifi calling unless u can provide to att an imei from a device that has wifi calling. Only feature u will get working is volte. It's different them tmobile.

Thank you for the answer
I am familiar with the need for an IMEI from a branded device ..... But I'm not even completely sure that's working for the S8+ like it did for my S7
I just haven't gotten anyone to 100% confirm WiFi calling on AT&T even with proper IMEI

Well i don't know from experience with at&t firmware but at&t should have wifi calling by default. If not and if wifi calling is an important feature towards you, then the last resort answer you have is to flash unlock firmware onto your device since that's the firmware everyone can use while it supports wifi calling and VoLTE (Voice Over LTE)

Once again, per other threads and myself, simply flashing the att firmware will only give you VOLte. You can toggle the wifi calling but it will say your account doesn't have this feature after about 5 seconds. If u call them and give them an imei number that is to a device that is an att device with the feature it will work. This is different then tmobile which will allow u both without doing anything except flashing their firmware.

Hello all ..... ( and @Tkkg1994 )
I'm still trying to get a definitive answer --- Has anyone personally been able to get an unbranded S8 or S8+ to activate WiFi Calling on the AT&T network (not TMo or others) ??
I'm trying to facilitate an issue with using S8 Ports on my unbranded S7 Edge where we can get VoLTE to work nicely but WiFi Calling will not activate (on the S8 port based ROMs).
I am aware (and have been for quite a while) that you must have an AT&T branded IMEI to get this to work on AT&T. I am also aware that this step is not needed on TMobile or really any other network.
I have tried the branded S7 IMEI that works great on my S7 to activate WiFi Calling while using many (most) S7 based ROMs. I have even tried branded IMEI's from ATT branded S8's and S8+'s .... but I can't get WiFi calling to activate while on any of the S8 port based ROMS (I get VoLTE nicely with many ROMS esp the latest BatMan S8 port ROM)
So to troubleshoot I am trying to confirm that even with the S8 or S8+ that WIFi Calling is or is not a possibilty ??
Thanks

I am no developer, but I believe there are two possible causes in the case of T WiFi failure on Exynos:
Perhaps T requires the IMEI to exactly match as a security measure, and since they cannot use an International model IMEI it will never work.
Or there is something specifically compiled for the Snapdragon process and so when it is extract it will not run on the Exynos.
Either way, it won't work. I posted a LOGCAT when enabling it failed, but it is beyond my capability to debug and no one seemed to be able to figure it out.
