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

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?

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?

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?

Hi everyone,
I installed following U firmware on my G935P with T mobile CP from latest G935T firmware. Everything works great (including WiFi calling) but VoLTE is not working. There is option in settings > networks to enable HD voice calling but enabling it doesn't help. I dont have any option for VoLTE prefereed in Phone Menu. I even tried enabling with QuickShortcutMaker to enable VoLTE. but doesn't do anything, I cant see HD logo while making calls or VoLTE symbol.

You have to flash the T-mobile csc to get volte working I believe.
Is that confirmed? I didn't realize we could mix and match CSCs.
Thanks
VoLTE does not work with the U firmware.
No you cannot use the Tmobile CsC, if you want your phone to boot. You can use the Tmobile radio aka the CP file

As @justda mentioned, No you can not mix and match CSS with different ROM. Only CP files are interchangeable between Snapdragon Models. You should use CP file from your carrier latest firmware to get better signal and more band support.

Just out of curiosity. Did anyone use 935U firmware, but XAA instead of TMB? For me, with XAA, VoLTE and wifi calling worked out of the box as soon as I inserted my T-Mobile SIM.

Flashing latest U firmware with T mobile CP fixed issue for me. I can confirm VoLTE for t mobile works on U firmware out-of-box with or without T mobile CP(radio). @walrusmonarch thanks until now my phone was on U firmware with July security patch. Not sure why it was not working, it's a used phone and the previous owner also made some rom related changes .
Btw, As per my knowledge, both firmware contains the same MULTI-CSC
(i.e. "CSC_OYM_G935UOYM4BQH3_CL12006533_QB14665430_REV02_user_low_ship_MULTI_CERT"). As per sim card inserted during first boot the phone will reset CSC code to match carrier. In my case, it will automatically switch to TMB, even if I use U firm with XAA default code as it contains the same AP, CP, BL and multi-csc file. correct me if I am wrong.
As the title says, I live in the US but bought a sm-g950fd from Pakistan while I was there. Software information tab is attached below.
How do I get to run spay in the US?
I have read a few threads about this but haven't found a definite answer. From my understanding I need to:
Backup and factory reset
Install UAE (XSG) firmware through Odin
Uninstall stock spay app and install the US one from apkmirror
Is this the correct way to enable Spay? How risky is it to flash the firmware? Will I lose OTA updates? My phone isn't rooted yet.
And in Odin, which file do i select in CSC. The one starting with Home_csc, or just csc ?
Here's what I did and got it working for me

I live in the US. The only way I was able to change the region is by using the method I linked. I literally everything before that, flashing different versions etc, but only by changing the Sim card did it work. Paid about 10 USD to have the Sim shipped to me. It's been a while since I did it so I don't remember the specifics, but my link is pretty detailed

Yeah, your method is very good. Any specific network to look for? And should I flash the latest firmware or a little older one?
So I managed to get an indian sim from a friend and installed the indian firmware. What happened is that my phone's CSC has changed, but it has changed to Italy (ITV). And apparently, Italy only has the single sim variant so I didnt get update to oreo as well :/
What should i do? get a sim card from another country and do the process over again? or just manually install the indian 8.0 firmware?
Samsung pay seems to work fine though

Other firmwares will work you might just be missing features like WiFi calling. I don't know the exact dialer code but they is a preconfig dialer code to select csc so once you got the latest you could try that. All the firnwares are identical for each us model you wont brick from flashing another carriers
So thats yes right? I can use other carrier rom without any problem?

My main concern is OTA is currently failing completely, I am hoping to restore by moving away from the TGY code, does that need carrier switching process or just flash 950U1 on top including user data ?

Im pretty sure u1 model pretty much is csc-less i would try to flash the u1 firmware directly and flash the home csc in u1 firmware which should leave it open. BL" "AP" "CP" "CSC" is all you should flash. User data would add a carrier. If you dont it will leave it open.....
If updates are all your lookong for. Just use odin to manually update

You are either using the wrong odin or a older firmware.
Or. To flash unlocked firmware you must first flash the combination file then unlocked firmware.
hope this is the right category. i have a problem:
- started off with a 930f original factory unlocked (purchased in europe new from an independent hw vendor), eventually updated (itself) to 8.0.0
- used it with many carriers all over the world, no problems ever (love this phone).
- last year, i needed volte on t-mobile in the u.s., so i rooted (super su) and installed csc from cscselection_v2.4.5.zip (the one based on the s8 csc i guess)
- works great
BUT: to my surprise the phone now seems to be locked to t-mobile: tried to insert my european sim, one i've actually used it with before doing the root/csc, and got the locked prompt... (side note: the sim is ok, works in other phone.)
- it does not have the t-mobile unlock app.
- (i grabbed a version of the app from an apk archive), but it says my phone is not supported),
- t-mobile support says there's nothing they can do: the phone never was a t-mobile phone, and was original factory unlocked for most of its life
- how can i network unlock the thing? (i'm not willing to pay for a service until i'm certain it would "work")
any suggestions? thanks
Flash stock ROM and root with magisk.

It would but it would also unlock your device, after unlocking your device you can try again with a different CSC.
Alternatvely you can use the codes available on the internet. Here is a full list of the codes.
hmm... i see... thanks. i'll try
