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.
I need some help with the s7 edge, I had brought the US version Snapdragon variant G935P device, but now I have flashed the Carrier unlocked G935U firmware to it and now it supports all carriers, (I use it in India now). But here in India the we have VoLTE calling, (though some US carriers have it, they have specific app for their VoLTE) . but I want VoLTE on this s7 edge. How to get it?
Can I change the CSC of the device to INS (Indian s7 edge firmwares) and get the VoLTE support or any way?
I am very much worried on this. Please help me to get VoLTE on this device.....
I know for some US carriers, people have created a patch file, when patching it to the G935U firmware, makes them enable to get the VoLTE for some T-Mobile, Version s7 edge devices... can it be done for my device also??
I am ready to help anything for getting this done..
Same problem from Hong Kong.
I am using a AT&T variant with G935U firmware in Hong Kong, with carrier "3-HK"
Without the VoLTE ability, whenever I dial/receive a call, it takes time to switch back to 3G before the call got connected.
Hope this can be eventually solved out.

you can get it to work,you download the tmobile nougat firmware form the T-mobile Galaxy S7 edge xda forum.Then unzip it after it downloads. Also download princecosmy's odin to bypass the SHA256 error.(You can find that there too). In odin,put the AP,BL,CP,and CSC into their cooresponding slots.AP can take a while to put into tis slot but will do so eventually. As far as the wificalling,it gives an ER06-Invalid SIM,and VoLTE wont work,although Ive heard of some SM-G935F users being able to get both features working

The link which princecosmy has for Odin isn't working. Can you share a working link?
I can't for some reason my account isn't letting post links for some reason,if check in the SM-G935A to SM-G935U guide to download the ODIN
Hi, I have bought an unlocked Samsung galaxy s7 edge (AT&T branded G935A). I'm using a UK sim and it's working fine. Only issue is I'm still stuck on Android 6 and each time I go to search for update it says my phone has the latest update. I want to know if I can safely flash the firmware to a UK unlocked firmware or even the US unlocked firmware?.. I don't care if I lose the AT&T items from the phone. Actually if I can lose those things the better. Thanks in advance for any suggestions.
You should be able to do this, as I've an AT&T S7 Edge phone unlocked for international use, and I've flashed things over and over without losing the unlocking
That's great, would it be possible to tell me which firmware you flashed it and a link if you have it. Much appreciated and thanks in advance. Did you flash it with the us unlocked firmware or international one. I want to flash it with UK unlocked firmware..

I flashed with the unlocked US firmware (U firmware) and it worked fine, flashing international won't work sadly. But using the U firmware should work fine, I have no link at the moment, but I'll search the threads and see if I get you one

so, did you update to the u firmware as mentioned above and how did it worked.
Please explain as I have the same issue but I am using the phone in India and I have the same at&t s7 edge.
please help me
please don't get irritated this is about an S7 Active and i have had no response on the S7 active forum
i have an s7 active that was frp and network unlocked. i am trying to use this on tmobile.
my s7 active is running android 7.0 G891AUCS2BQC2
sms, mms and emails seem to work but not the wifi calling option. the wifi calling option is greyed out under settings.
i need the wifi calling option and like the S7A.
in posts regarding the S7 (not active forum) and S8 active i saw thoughts of needing to flash tmobile software to get this to work
any ideas?
thanks
You need to install the T-Mobile firmware.
even if your phone is unlocked, it is still an AT&T model
