Any way to get VoLTE working with international phone? - Samsung Galaxy S8+ Questions & Answers

Hello
I bought an s8+ from HK which is the dual SIM Snapdragon version (G9550). Using it here in Australia, everything works as expected as it supports all of our bands, however VoLTE does not work. I've read this is because the CSC does not match a local CSC.
Unfortunately there are no Snapdragon versions sold here, hence no firmware with the Aus CSC (XSA) that will support VoLTE (as I read you can't flash the Exynos ROM onto the Snapdragon).
Is there any way I can enable VoLTE? Can I somehow change the CSC without an official ROM? Like go into the G9550 ROM and replace the CSC with the Aus CSC?
The only other region with the Snapdragon is the US from what I can tell, which probably wouldn't enable VoLTE either.
Any advice is appreciated
Thanks.

You may root and then flash your csc zip (or simply replace the CSC files in the custom rom with your CSC files). You should get VoLTE. Download Multi CSC file from here and extract your csc.
I do the same but with India CSC on USA snapdragon models.

Thanks nimms. This is pretty much exactly what I was after, except I cannot root the phone (work required Knox so I can't trip it ). I was hoping I could do somthing like the above, only via Odin, but it sounds like you can't change the CSC without rooting the phone due to making system changes.

Try this code in dialer *#272*imei# and change your csc from there

Hi
As far as I'm concerned, this is not possible without tripping the Knox counter. And if you try flashing the XSA CSC (via Odin), you will definitely soft brick your phone

ims setting. maybe can fix your issue ,just download a hidden app display. then you can open ins setting

Odin won't even flash it, It's pretty hard to soft brick this phone with official tools and firmware.

Yes
Odin won't flash it but if you try to flash it and after that you reboot, you will stuck at download mode. Only by flashing the correct files, will make it boot

Interesting.
Another question...the only difference I've noticed between the 9550 (HK) and 955U (US) is that the US version does not have Band 28 but the HK version does, which we do use here in Aus.
If I flashed a US firmware (which has the same S835 SoC), would I lose Band28, or would the modem still be able to use it?
EDIT: what if I only flashed the CP file (modem), is this interchangeable between the different SoCs? Could I flash the XSA CP (modem) onto another ROM, or will this soft-brick?

My IMS is saying "Not registered" in the about phone. I can't seem to do anything about it, and the hidden menu doesn't give me the option to change it.

IMS setting is located explicitly on "Settings -> Mobile Networks -> Access Point Names"
The best bet you may try is to find a Samsung phone thats currently in VoLTE then copy IMS apn settings onto you phone (you manually input the settings).

Do not enter people astray, ADB Sideload It's not working - error "signature verification failed"
need ROOT
VD2-CSC-S8S8p
MY Galaxy S8+ SM-G9550, SW - G9550ZHU2AQL2

Just download an official ROM (A variant from a country that supports VoLTE) for ur model from sammobile or u might even find it on the xda forum and flash it via odin with Home CSC.
It works well... No need to root n KNOX counter wont be tripped...
PS: Backup data.. They will be lost in the process.

Now we're talking about ADB, not ODIN or TWRP.
Flash via ADB Sideload - not possible. You understand me. Smartphones snapdragon not flash Exynos SW. You can only edit an existing profile CSC or add new CSC.
Example:
my smartphone TGY (snapdragon model SW)
but I live in the region of SER (EXYNOS MODEL SW)

Right, My bad... I missed the international part itself...
But as far as i know, Exynos CSCs also dont go with the Snapdragon CSCs... I could be wrong.

Basically just want to know what would happen if I flashed carrier branded csc only with Odin.
E.g. would my phone refuse to boot, would my phone be carrier branded if it succesfully boots, trip Knox, etc...
Any info welcome - tired of googling the answers or searching XDA forum for answers.

Might have some carrier preinstalled crap but it won't trip KNOX nor prevent the phone from booting

That answered some of my questions, thanks.
Please see screenshot for my mutiCSC firmware. I am running Android 7 but haven't changed CSC since I got the phone in December 2016. I got it with Marshmallow on it. Everytime I upgrade firmware with Odin I select Home CSC so my CSC never changes.
Since the solution is in the CSC (afaik), which CSC do you recommend I flash with Odin? I understand how to flash with Odin if CSC not in my multiCSC firmware (tick re-partition, etc...)
My home network is Vodafone (CSC is XVF which is not part of my CSC).

If i got it right you are not root, right? if you are root there are other ways....
Yes you need the right CSC to make it work , in this case Vodafone XFV.
When you change to a different CSC is recommended to check re partition to adjust to the possible change in partitions
https://www.sammobile.com/firmwares/galaxy-s7/SM-G930F/XFV/download/G930FXXU1DQD2/131635/
Download the firmware and extract the correct CSC from it , if you do not want all the vodafone stuff you could download and unbranded firmware and use the BL ,CP , AP from it and the CSC (XFV) from Vodafone and flash it all together
BACK UP FIRST .......

Yes, no root (for now). Will only root in a year when I get my upgrade on my contract.

[HOW TO] VoLTE on Jio India - USA Snapdragon S7 S7edge

New instructions dated Sept 15th 2018
No root needed.
Should work on all Snapdragon USA/Canada etc models (ATT , verizon, sprint, tmobile tc) S7 or S7edge (though the file is from S7edge India model). Leave a message in this thread if you encounter any issues.
Am not responsible for any damage you might do to your device.. am just trying to help.
Keep your Jio SIM in the phone all along.
1. Back up your data using Samsung smart switch or any other means (save whatsapp chats to google in settings)
2. Flash stock firmware (On unzipping stock FW, you'll get AP, CP,BL and CSC files. Use Odin to flash them) (Don't flash User data file if it's there in extracted files) - Download from Updato site for faster downloads
Use recommended patched Odin is located here
3. Download the Indian CSC file G935F_INSCSC
4. Ignore this step if you have adb working on your PC already.
Install "minimal ADB fastboot" program on PC, Copy the G935F_INSCSC.zip to your minimal ADB folder on computer (under program files on C drive).
Double click cmd-here.exe in that folder.
5. Boot the phone to recovery mode and choose Apply update via ADB sideload
6. Connect your phone to your computer with your USB cable.
7. On ADB window on PC type "adb devices" without quotes. Next line should show a device attached
If seen, type "adb sideload G935F_INSCSC.zip" without qoutes. It'll start transferring the file.. check mobile screen it'll install itself. (you might see some errors)
8. Reboot file and check, you should have Volte.
Possible errors:
1. Phone app/Msg app force closing
Try SMS app from google
Reflash AP BL CP only excluding CSC
Install CSC zip via adb again
2. Sprint OMADM app needs to be removed to avoid annoying notification or change notifications to low priority
To remove via ADB, turn on usb debugging
type in adb shell
you should see a dollar sign.
next type in pm uninstall -k --user 0 com.sec.omadmspr
it should say success.
ADB sideloading is explained in this video in the last https://youtu.be/giD7nP4Oue4
Old instructions have been deleted....
Thank you Proper vlog on youtube for testing my method and reporting.

I see the device security been disabled and when i try to open it , it force closes . does this means Knox is disabled and thats why i am not able to add any cards in samsung pay ?
Can you please help? . I need to have samsung pay working ?
Is the CSC file you included only take care of Jio VoLTE or stuffs with all operators ? . I hear that Airtel is even testing VoLTE.

I've only tested till login. Tried to add card after reading your comment. I too had connection error. I've only changed CSC in that file. US guys didn't have any issues it seems.
I can't open some pages on spay too.. not sure if it's related to Samsung servers or our device. I'll check later.
If it were related to knox issue, it won't even let you login. (Like on a rooted device).
VoLTE is related to CSC and device model. So it should work with airtel too. Lets see.

You also try and keep posted. If you want me to try something on this , let me know.
BTW , do you have the latest csc files for india thats ODIN flash-able ?
Also will it be an issue because of the samsung pay framework. I hrd that it need Indian framework and India spay app for successful adding of our cards.
Do you have any idea as how to bring spay India framework to this rom ?
Thank you for the input man.
I just wonder if the CSC is CPU dependent? Since I want to modify it with a CSC for HongKong, I am not sure if it matters for Exynos / Snapdragon rom.
Or would you mind help me to modify the file with Hong Kong CSC for me? thank you very much!

CSC is not dependent on processor as long as it's flashed via twrp/flashfire as a zip. But odin flashing is different.
So, which is your device? if it's SM-G935F/FD/K/L/S/W8 then use https://forum.xda-developers.com/s7-edge/development/utility-flashable-csc-selection-30-t3392957 TGY is in that zip.
If your's is a snapdragon, i'll help.

Hi, I just did as what was instructed.
After I have gone throught the Auroma screen, having checked No Wiping and Keep SU, ticked what to debloat,
it says finished and restarted.
1. When it was rebooting, it keep popping up com.sec.epdg has stopped, IMS Service stopped.
Is that normal or what else should I do?
2. I also noticed the modified file for India is over 500mbs, but the TGY file for Hong Kong is just 153mb.
Is everything alright about that?
3. When I try to Odin a stock G935U firmware wiping everything, it turns into Olympic Edition Theme, and I lost my IMEI , cannot detect a Sim. There is no way for me to get it working again
thank you again.

I been using various versions of Odin and Various version of Firmware, including MM and Nougat, G935A / T/ U,
Also I tried to tick Re-Partition, Wipe NAND.
I also even tried the INDIA CSC file on the OP and the original NoNaMe Mod file.
Still, it says SIM Card Not Available, IMEI Unknown, Baseband Unknown, No Network. It used to work fine before trying the TGY CSC.

Smartswitch detected my phone but says G935A is not supported.
Finally, I approached a phonedealer in China online.
He fixed my phone remotely via Teamviewer, and he said the Certificate of Modem/Baseband was corrupted. Since the Baseband gone missing which cannot be fixed by ordinary Odin of Firmware.
I saw him used some kind of unofficial software (characters illegible to me) and got it fixed in 2 minutes, and was luckily costed me only 220RMB (around 30USD)
Well, a good lesson to learn from. There are really something not fixable by Odin and we could Eff our phone up even with the bootloader locked.
Again, it was just me requesting the OP to modify the file for me to satisfy my curiousity who happily did me a favour, there is nothing to blame with and I thank you again for all the help!

Sorry about that but the file will touch only CSC part. not basebands/modem. I've re-checked the zip too.
Not sure what happened.. I could even flash Exynos CSC file via flashfire on Snapdragon. No damage at all.

CSC Changing Help

I have the G955FD on the BRI (Taiwan) firmware. I live in Australia, and really want to use Samsung pay. How should I change my CSC from BRI to XSA? I've seen varying information here and on other sites. I want to keep my Google Play as Certified, still have OTAs and without tripping KNOX. Essentially like a standard phone from this region. I don't particularly care about Dual-SIM, but it'd be nice to still have.
Here is my current software information: imgur(dot)com/a/197z5 <-- I can't post links yet, remove this if not allowed.
Thanks for helping

Hi mate
Without root there are not many options ..
First F and FD firmwares are compatibles ( same device!! exynos to exynos) , you can flash an F firmware into an FD or vice versa
you could try to change your CSC to your SIM card CSC first
Check here
On the thread it shows how to add your SIM CSC to your current CSC config , if it work you may end up with a configuration like BRI/BRI/XSA , in my case I got TPA/TPA/PCW , TPA was the software default and PCW sims CSC. I do not have Samsung pay so i do not know if that change will be enough to make it work. Back up you need to factory reset for this.
The other option is to flash a full XSA firmware ( use a G955F firmware) , read here how to do it
BACK UP before you do anything

Thank you very much! I'm now running XSA/XSA/XSA with a flash. Dual-SIM support is still there which surprised me. There were some issues with Odin, but I fixed them up after a while.

Great news mate!!
Firmware is 100% same for F and FD so you should not see any difference at all , I asume also you got Samsung Pay working.
Good job!
I did the same when I had s8+. flashed TEL (Telstra) SM-G955F firmware which I got off Sammobile and worked like a treat. Samsung pay, VoLTE, Wifi Calling, Spam detection in calls worked as well.
I upgraded to S9+ and tried to do the same. The flash process works fine but CSC doesn't change. I am stuck on AFG CSC. Apparently it cant be done on S9 as Samsung is imposing multi CSC format.
Well, you are lucky one to have S8+. Enjoy

That's unfortunate
I'm curious why you flashed TEL instead of XSA, XSA is the unlocked version and it still has WiFi calling, VoLTE etc. I have an ALDImobile SIM (which uses Telstra) but I installed the unlocked version to have minimal bloatware and the stock boot logo.

I tried both. First preference is always XSA but I tried TEL in anticipation that it may work

Question XSG csc

Hi guys i bought a galaxy s22 ultra (S908E/DS) and i saw it now the the csc is for Arab country. i live in Bosnia (Europe) is there any way to change the csc to eux? thansk for infos
I guess you bought device is snapdragon and you needs a CSC which available on;y on exynos. If there is no issue with network then better keep as it is.
Alternatively try flashing HOME_CSC file from stock firmware of EUX, most likely it may get block by odin. In this case only way is to root device and force install EUX CSC, again I don't recommend it if their is no valid reason to change.

yes its a snapdragon model. i have no problems with network yet shoudl i try over odin to flash the whole firmware or just the home csc file? is there any chance to brick the phone because its a snapdragon variant? i ask because of OTA updates?

If you are looking for OTA, you never get Exynos OTA on Snapdragon.
You can not flash full firmware, I'd suggest to flash standalone CSC file in case you have network issue. If you have everything working related to network, I strogly suggest to NOT to mess up. Still you will get OTA when you have new update for arab country.
why i cant flash the full firmware? is it because its a snapdragon or something else? can i mess up my phone when trying to flash the csc via odin and download mode?

It is not possible to change CSC without tripping Knox. You must unlock the bootloader to change the CSC.

Unlock the bootloader and use Odin to flash OXM firmware. OXM is multi-CSC, so you should be able to change region to India.
Don't forget you can use the Search function to look for solutions to questions that have been asked many, many times before.

If you unlock your bootloader, you can install any CSC you want, so you'd just download INS firmware and flash it using Odin.
Or, you can flash the OXM firmware and simply change the region to India, as I stated in my first reply.
Ok i got that now second major issue is that i cannot unlock my bootloader as my developers option is not showing oem unlocking
no need to unlock your bootloader to change the CSC, just use this application to do so

Can you suggest best US based csc with regular ota updates as i am not getting ota update on gcf....stuck on may security patch update....
Can GCF based devices get ota updates i read it in someone's post that they can be only updated via odin or sideloading
GCF gives more LTE and 5G bands support so maybe that's why your phone has it set on that. You can change it to XAA as it's bloatware free and gets regular updates.

Wanted to ask it just out of curiosity....there is no way to change my csc from USA version to Indain version....by any means?
I don't think this is possible... and that's why Samsung has different variants for different countries ...
Okkk....
But by any chance u get to know that it can be changed to Indian csc please do let me know it will be very helpful
Thinking of flashing this firmware update via odin....device model number : SM-S908UZKEVZW
Region:VZW
OP, Are you sure it is an "unlocked" version? Based on he last three charactors of the model# you provided says it is a Verizon branded phone. Yes, technically it was unlocked after 60 days, but since you are not connected to Verizon's network, that may be the reason you are not getting OTA updates.

As for unlocking the bootloader, none of the US variants' bootloaders are unlockable.
I changed my csc code from GCF to USC and now in sim card manager settings it is showing only sim1 option and esim no sim2 option is available
