Finally working method for enabling VoLTE on S7 Edge on latest BTU firmware (no root)

Hello Guys. I've been playing around with all available nougat firmwares to get volte working. I succeded using latest BTU firmware and beta 1 files.
I'm not responsible for any issues with phone after using this tutorial. Use at your own risk.
With this configuration Shealth doesn't work. It says device has been compromised. Knox is not tripped but probably the cause is a mix of firmware files from different builds. I am looking for a fix but for now you have to sacrifice Shealth if you want VoLTE working on BTU firmware. Flashing full BTU firmware back is restoring Shealth functionality.
UPDATE - After flashing back DQB3 bootloader VoLTE stays and Shealth start working So flash DQB3 bootloader and DQB1 cp file at the very end to get everything working!!
This tutorial is temporary solution until branded operator firmwares will be released.
So what we need:
Official latest nougat full firmware - DQB3 at the moment
Beta 1 BL, CP, CSC files
Odin
Samfirm
To get VoLTE working follow these steps:
Enable oem unlock so you can use odin to flash firmwares (oem unlock is in developer options - enable them tapping About device/software info/Build number few times).
Flash full latest Nougat BTU firmware - (available on samfirm)

}
After flashing completed, skip all configuration because phone will be factory resetted again when you flash beta files. Now flash Nougat beta BL, CP, CSC which are available here: Beta files
After flashing configure phone as normal (i skipped restore settings in samsung cloud just in case of something overwritten).
Flash back Stock Nougat DQB3 bootloader.
Enjoy working VoLTE on latest BTU firmware

Thanks I'm doing this later.
If I'm already running on DBQ3 do I need to do the first bit?

thanks bro.... turkey s7 edge developers

VoLTE being enabled is in the CSC file only
There is no need to do this double flashing technique.
Stock Nougat BL
Stock Nougat AP
Stock Nougat CP
BETA 1 CSC
One time flash, finished

nope, i tried many times. Only flashing csc doesn't bring me volte. Only when i did what i stated in tutorial volte started working. So looks like if it working in your case doesn't mean it will work for all people. My method will i believe

No need, flash bl cp csc only. It will reset your phone.

Strange, flashing Nougat files + BETA 1 CSC once has worked for other people in the EE thread. It is well known that all the code needed to enable VoLTE and WiFi calling sits in the CSC file, hence why most guides suggest you flash all 4 files in ODIN but use the CSC file of your choice for carrier settings. If the user is rooted, simply extracting the CSC folders from the CSC image and dropping it into /system is enough and doesn't require any specific ODIN flashed bootloader or modem file.
Mixing different system image and bootloader files isn't really recommended

Like I said before, of course it would. VoLTE does not depend on the modem or the bootloader.
ALL of the code enabling VoLTE is in the CSC file

I have followed instructions on post 1 on my s7 edge dual sim on 3UK but still not getting Volte - can anyone help?

It is hard to say why you not getting it. Solution worked in my case but im on EE uk. I tried hard and no other solution worked for me.
Did you flash full dqb3 rom first? And then those 3 files?

Flashed from MM to Nougat, with original BTU file from sammobile and VoLTE worked in an instant.
so i think it the depends on where you live

Changing CSC without root

Is it possible to change CSC with the end result being unrooted? By this I mean if it requires me to root in order to change CSC that is okay, but then can I unroot while keeping the CSC I changed to? The reason I ask is because I want to be able to use banking and other apps (I've read that root prevents these apps from working) but at the same time I want to have wifi calling and voLTE for my carrier.

Right, without root, all you need to do, visit sammobile and download then flash the compatible image from the carrier you want to switch to. However, be aware, of hardware limitations i.e.) you cannot flash a snapdgragon fw on a exynos phone for example.
Now if you had root on the other hand, you can do this in a matter of mins and not loose any files.

I wanted to use a CSC that allows AT&T wifi calling and voLTE. This thread https://forum.xda-developers.com/ga...ility-flashable-csc-selection-v1-0-0-t3605264 shows that it is possible to flash USA Multi-CSC using TWRP and root, which includes AT&T. So is it possible to have this CSC on the G955F while being unrooted? If it requires me to root and then unroot in order to change the CSC, I would be okay with that too as long as the CSC stays.
Based on what you said, I'm assuming the answer is no because the AT&T variant is the snapdragon variant, so I'm guessing that means the CSC wouldn't be supported in exynos unless flashed via root and then remaining rooted. Correct?

if you have Exynos phone you got root as an option

Right, but the problem is that with root I won't have access to banking and other apps. So I was hoping maybe I'd be able to root, flash the CSC, then unroot and find a way to keep the CSC. Basically, on exynos, I want to be able to have the AT&T CSC and banking apps at the same time.

i have the 955FD with an ATT CSC and Wifi calling isn't working and i can't visually tell if VoLTE is working. next step is to get an ATT imei assigned to my number to see if that fixes it. bottom line, changing to ATT CSC is not guaranteed to get the aforementioned services working on your 955F.

Root it , fix it and get voLTE then use hideroot to hide root on that banking apps .

What do you mean with "Factory Imei"? It's a menu or something? In phone dialer that code doesn't work...

Same question here what does "Factory Imei"? It's a menu or something?
Also in step 3 assuming you have to put the CSC of the new CSC area you want. Also usually you flash CSC and not HOME_CSC. In this case it is reverse, any reason why ?

i have same objective as yours, i have SM-G9550 which is hongkong variant (non-root) and it is snap with 6gb pf ram and 128gb of rom. I want to change CSC to Thailand (THL) to use VOLTE and VOWIFI. But problem is Thai variant is EXYNOS paired with 4gb of ram and 64gb of rom. So is there anyway to work this without root as i need to use Knox and samsung pay so root will deatroy it correct?

You could try from the phone dialer: *#243203855# that's to change CSC, keep in mind it will reset your phone so make a backup first. The screenshot shows CSC for Canada since I'm in Canada.

You can change the CSC region successfully using @ngominh's method.
But you have to find "The Combination" file for your phone to do it and that
is usually a "Paid" firmware which is different than your normal stock firmware!
You find that and you can change the CSC successfully!

[Help] Changing Service Provider SW

Hey guys, I bought my s8+ 955FD in Thailand, and no matter what I flash the initial language is always Thai, the Google Playstore is always set to Thailand, what I realised is that the Service provider SW ver in software information is always set TH/TH/TH, is there any way to change this?

Yes there is. Find a CSC package which contains the country language you wish. Make sure the CSC package is for the same version of your overall phone, which if stock may be a 950F, or what ever. flash the CSC with Odin. Do not use the Home CSC from the package, as what will leave your CSC as TH. Some folks have talked about with new phones you need to get a SIM card from the local where the phone was 'meant' to be used, and use if for 5 minutes, so that will effect the 'unlock' ability to be used for other regions. Check into that, as well.
If you decide to change the overall software on the phone, 'F' packages seem to work pretty well. If you do decide to flash an F ROM, you also need to flash an 'F' CSC (multi) package, where you can select the country you wish and the carrier from the install dialogue.
Often the preferred installer for custom ROMS seems to be Aroma, as it is a very flexible installer for ROMs and about anything you can think of to add onto or into a ROM can be incorporated into the Aroma installer.
If you are not going to use a custom ROM, then you will flash a CSC package from Odin, but again, first check to see if you must use your phone for 5 minutes from the SIM local.

I have flashed multiple stock roms with their respective CSC and it does not work that was my question

Have you used the phone for 5 minutes within the originating region?
"Some folks have talked about with new phones you need to get a SIM card from the local where the phone was 'meant' to be used, and use if for 5 minutes" . . . in order to functionally unlock it for out of the region use. Is your software that version?
When you flash the phone, what SIM is inside the phone before the reboot?
Are you rooted? If so flash via TWRP and a CSC which has an Aroma installer.
What else can you tell us about the specifics of your phone?
If you re-flash the OEM firmware, or when your first setup new, do you get any language options on the start setup page, besides Thai?

Dear Jeff, thank you for the help and the follow-up. I have managed to change it partially by inserting a new SIM from the new country(Brazil) and when I did so, it asked me for a reset and I went through with it, now it's ZTO/ZTO/THL ---- so the first two changed to Brazilian CSC but the third one is still THL, any thoughts? what's the difference between the 3? And yes I had used it for a lot longer than 5 minutes when I was in Thailand. I just want to get a clean install without any remnants from THL - I am currently on CRAP/CRB7 - Waiting the 7 needed days to get OEM unlock and be able to flash TWRP(from what I understood), please tell me what to do to get rid of the THL from my phone completely. Thank you So much

Once rooted, find a multi-CSC package with your country and flash it (again). You might need to flash the baseband, so I'd look into that, as well.
On an S7 from with a Chinese CSC, once I found a custom ROM, , I flashed TWRP in Odin, booted into TWRP/recovery, flashed the custom ROM, verity and SU, and then flashed a multi-CSC package Aroma package, mine lost all the Chinese info.
Sure would be great if these phone companies would just give us unlocked phones, with straight forward methods to make these simple changes. I think most folks would pay a little extra for the ability.

Hi Louayd. Did you fix this issue?
I'm passing the same problem with S9+. I bought in Portugal and trying to use in Brazil. I can't root phone because my intention is use the Samsung Pay and it with rooted phone it doesn't work.

I am facing the same issue. I bought Note9 from Singapore from M1 Operator. I have flashed different countries ROMs but my phone always keep some bloatware from M1 Singapore and the "Service Provider SW Ver" always show MM1/MM1,MM1/XSP despite whatever country/region Stock ROM I flashed. My phone is already OEM Unlocked.
Need support if anyone has managed to change it.
I do not have Original Country SIM to test as mentioned above. I bought it from Singapore and wanted to use it in Cambodia. Right now VoLTE functionality is not working.
I tried to use ShortcutMaster app also but it is also not able to show anything under IMS Service and Settings.
Regards,

150 fw was released for 636 for more than a week already.
152 was just released for 432 recently.

Hey, thanks for quick reply, can you hep me with something, don't want to brick my device.
i'm on huawei P20 PRO, bought it unbranded, i'm in France, i unlocked the bootloader and rooted the stock ROM ( magisk ) with custom TWRP , did not do anything else at this day. ( pic attched )
i'm on 131C432, i want to manually update the update to "152"C432 with GPU turbo ( pic attached from app Huawei Firmware Finder ), i saw full firmaware was available ( see pic attached )
My question is, can update with HuRUpdater method following the steps from the HuRUpdater Thread, without debranding, rebranding etc......... it won't relock my bootloader right , i'll just place his recovery into .zip to keep custom TWRP, flash full 152C432, then root.
thanks for lighting me the situation i'm into

Yes you can flash it via hurupdater no need to relock BL or rebrand or rebrand. If you want to keep twrp put the twrp.img (renamed to recovery.img) in the same folder with the fw and hurupdater.zip

hi there, can you elaborate on this?

5. Using Settings Editor app enabled 4G only mode.
will this work on other networks outside India? I´m in Vodafone Portugal, and all set with my sim but there is no way to get volte to work.

If you have rooted your phone successfully, Install ES explorer, In the menu allow root explorer.
THEN
GO TO DEVICE, SELECT SYSTEM-> VENDOR-> BUILD.PROP
IN BULID.PROP YOU FIND THE LINE COMMAND
ro.config.hw_volte_on=true
ADD THIS COMMAND LINE AFTER THE LINE
ro.config.hw_volte_dyn=false
it should be like this ro.config.hw_volte_on=true
ro.config.hw_volte_dyn=false
AFTER ADDING SAVE AND REBOOT YOUR PHONE.

I´ve done that on an previous firmware version and it didn´t work. No VoLTE, not even the option to change on the call settings. Are you sure it´s working on all suported carriers?
Anyone else outside India tested this?

Technically If your bands are built into the modem and restricted by region model it can be enables. For me, I have bought a Singapore Model and in India the device is not showing enabling VoLTE for carrier Airtel although it shows for a 4G only carrier JIO. I used this mod to get VoLTE on Airtel too.
So your issue might be the LTE band used for VoLTE itself not supported by the modem.

Use current version to search in the website.. You can find yours at about screen. Mine is Clt-l29c636. you can use your model to find your firmware

thing is,
my carrier band is exactly the same as JIO
so it definitely not about the band
do you set manual APN for your VoLTE btw ?
i tried setting up IMS apn, but everytime i save it, it disappear from APN list

I havent set Manual APN I left whatever carrier set. Giving false to the volte_dyn setting will give you an option to enable volte in network settings. Thats what I did.
Above that I am unsure what is happening in your part of the region.

Please confirm the correct FIRMWARE before Flashing or Using Odin. I will not be Responsible for any Errors or S22 Atomic explosions or soft and Hard BRICKS.
Before posting, Please go through thread and check forums, am sure most Questions have been asked and answered.
PLEASE note: I stand to be corrected. Still working this Letters out.
Thanks.

Good, do it.
Thanks

Thanks for the topic.
CheckFirm states AVC9 is the latest test build (XSG)
eagerly waiting.

Welcome....
Currently on AVBF and it's all smooth and battery is good.

welcome

Looking forward to an update channel for the Sm-s908e thanks

Hey all, SD owner of S22U.
Just to let you know, I blindly flashed AVBF with Odin with the old mentality that 'OXM' firmware is multi-CSC with another region's AVBF firmware - where my region (XSA or OPS) was still on the AVA (January) firmware. Using HOME_CSC (didn't wipe) all flashed 100% and phone working 100%. So OXM from any region appears to be multi csc and you don't have to wait till your Telco releases the update (in my case could be months before my Telco releases updates/security patches). Correct me if I'm wrong please - but again - all went well and my phone has all functionality as it did before. Now waiting for the new update AVC6 to release for the SD S22 so I can update manually again. Also, thanks to @AwesomeARC for starting this thread - was waiting for this and will be very handy

Hey
Thanks for the heads up. I was thinking of doing the same but was not sure. Thi is my first Snapdragon device and was not sure about the OXM. Reason I created this thread.
So if I take the latest Firmware from Exynos 908B OXM region, and flash it will work just fine?

Y don't u just use the avbf firmware for the 908e and save the risk. If u look on sammobile there is quite a few to choose from. I personally use xsg which is uae. Use frija to download that. Works great

Flashing S908B on S908E will not work. Odin will fail during bootloader and if other components gets flashed before this, you will have non booted device(Soft bricked). Also no needs to mix up S908B link in OP, just stick this thread to S908E subject.

Also some suggestion for OP
You should organise OP for some Tool like Frija, Odin
How to get stock firmware
How to Flash
Latest available firmware for region
CSC included in multi CSC
OTA links
and much more, which helps a lot for other usesr,
Look this thread for example @henklbr was amazing person and mainainer for most Samsung flagship device, unfortunately he is no more. RIP henkblr

No, I think you guys must have misunderstood. I would still/only flash S908e firmware, but for example: I'm in Aus and there's no 'new' update for XSA (or OPS - my carrier).
I searched Samsung firmware at the time and found another region had AVBF (S908e) with March sec patch whereas mine was still showing 'no update' for my region.
This other region (can't remember which csc it was) had same lettering on the file 'XXU1OXM'. Downloaded that file and on unzip ensured CSC/Home_CSC was 'OXM'.
This suggested to me that, like the Exynos S21 I had, that the ROMs would be multi-csc for the SD version of the S22 (probably for all variants of the new range).
Flashed away with Odin and all successful. Phone updated to new software and sec patch and I don't have to wait for months before my carrier decides to push the update through.
Therefore, like the Exynos versions, you can flash SD with another S908e region's firmware so long as the files are XXU1OXM and not anything else.... Again, happy to be corrected....

Just to support this, my experiences are as follows:
Flashing other regions' firmwares for the same model (ie. S908E as per the thread title), that are within the same multi-CSC (eg. OXM), should not cause any issues. You will also retain your local CSC unless you take specific actions to alter this (don't bother). You can indeed get the update sooner through this method without issue.
My experience is that this also retains KNOX and factory status. No concerns at all. You should continue to receive OTAs as they are released to your local CSC.
If you flash HOME_CSC_OXM, your data should also remain intact.
Attempting to flash a differing model firmware will fail and cause a bootloop. Don't do this. If you do, flash the correct model firmware to rectify.
Just my prior experiences, mostly from previous devices. Presumably this remains true to date.
