Hi,
I'm looking at changing the firmware on my S7 EDGE from EVR to BTU.
How do I ensure I keep the data on my phone? Will OTA work properly on it when I flash the firmware?

So if I use home csc I can't use OTA?
How do I retain the EE WiFi calling option?

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 thought the WiFi calling option worked on BTU but Volte did not?

I'm from xsg CSC, I flashed mm via Odin with BTU firmware and home_csc also from BTU firmware. I registered to beta programme and got update, now I'm on stable nougat.

Was the update using OTA?

I have BTU factory unlocked and unbranded device and I can confirm wifi calling works on EE. Just enable it in the settings.
I debranded mine from Virgin UK to BTU, I have no wifi calling options although it doesn't bother me as I don't use it anyway.

Which firmware are you running G935FXXU1BPLB??
When flashing from EVR to BTU, what items should be selected?
BL, AP, CP, CSC (or CSC home)? I'm not fussed about VoLTE as EE keep having outages, however I do need WiFi calling. I tried flashing Nougat last night and selected BL, AP, CP and CSC but WiFi calling option was gone from settings
Thank you

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?

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

Hello
T-Mobile USA released nougat and I want to use volte and wifi calling. I've tried extracting the csc and flashing it along with my rom which uses aroma installer but it causes constant com.android.phone has closed errors. I'm trying to use renovate rom.
I have the 935F model.

Here is a custom Rom which has t-mobile Wi-Fi calling and volte built-in.
https://forum.xda-developers.com/s7-edge/development/rom-nougat-7-dplt-wifi-calling-volte-t3540723
You must be on the mobile network in USA or tmobile network in Europe and you must be using a T-Mobile sim card for Wi-Fi calling and volte to work.
Good luck, have a great day.
Hi,
Aim:
The aim is to get VoLTE working so that the phone can work in India on the Reliance Jio network. "Work" as in makes and receives calls through the native phone and messaging apps.
A bit of context:
I have a Samsung S7 Edge SM-G935F.
I am want to use the phone on a network that is 4G only meaning I need VoLTE enabled for the calls and texts.
Currently I am running the XEU firmware, but VoLTE is not working when I use the Reliance Jio sim.
PDA: G935FXXU8ETI2
CSC: G935FXEU8ETI3
If you need more context info let me know.
Questions:
So, basically, I am trying to figure out the easiest, non-intrusive way to enable VoLTE without having to unlock bootloader, root the device, etc...etc. (don't even know if it is possible this way). Anway...
The first question is, can I flash a VoLTE firmware from region/network A and use the phone in any other region/network B? Will VoLTE work? Or is the VoLTE firmware specifically programmed to work networks in a particular region or a single network in a region? For example, can I flash EVR (EE UK) firmware (I think it has VoLTE feature enabled), and use the phone in India on the Reliance Jio network.
( If the suggestion in the first question is not possible )
The second question is, can I flash a SM-G935FD INS (Indian) firmware on the SM-G935F to get VoLTE working? Is it safe to flash an FD firmware to the F variant?
Thank you,
Ray
Hello, you can run Volte and Vowifi having root, you only need to know the operator's data settings for these functions
"Currently I am running the XEU firmware, but VoLTE is not working when I use the Reliance Jio sim." Does it work with another sim? Thats the impression I am getting. If it works with another sim and not your current one then it may be as simple as the phone provider not supporting the device for VoLTE. If it is a problem for all providers then you will need to change to a firmware with a CSC that supports VoLTE.
I'm facing the same Jio VoLTE problem on Moto G7 XT1962-1
