Anyone who owns G930F and didn't have VoLTE or WiFi calling enabled on Nougat firmware BUT managed to get it working afterdoing "x" please share how to do it.
I'm tired of waiting for my Network to release the firmware...

My service provider supports both techs.

Of course they do! :good:
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.
Thanks, you basically confirmed what I suspected. Just needed a Jedi to point that out so I have peace of mind. I shall report back... :highfive: :good:

No problem mate.
Let us know how it goes
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.

And for S7 UFirm_INS_Hybrid_NoNaMe_PS_BS_Free_G930U_QE2_V2 zip
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.

Thanks for letting me know.
I will also try with a clean install of the system without removing any bloats and check.
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.

1.Edge closing might happen on first boot. did it FC even after a restart?
2.India file had S8 apps and Google play apps and your file did not.
3.Olympic theme could be a default for your CSC and please flash Your region CP file or U version CP file and see about that IMEI issue. if all fails, do a total clean flash of U firm with CSC and tick repartition in Odin. (not home csc)

Sigh, no luck
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!
Cheers!

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.
May be am just lucky.
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

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).

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)

I have official Israel Stock rom android 8.0, SM-G930F

CSC: G930FOJK3ERL2
So the problem is that i don't have any option to turn on Wifi calling or VoLTE from any phone setting/dial settings.
I checked with my sim card company if they provide this services and they do provide.
I re flashed my phone using Odin but its still did not changed anything.

You are using 012 mobile? Yes?
That is a virtual network which uses Orange/Partner (PTR)Network, flash PTR firmware for wifi calling to work.
The CSC part of the firmware tells your phone what services are supported on the network you are connecting to and will install those option when flashed.
You can also stay on the current firmware but flash a CSC zip file where you can change the CSC code on the phone for the network you want in your case PTR.

Yes because 012 mobile is using PTR network, an unbranded firmware will contain lots of CSC codes for your region/country and automatically choose the right one when it connects to a network. If the network supports wifi calling it will then have the option on your phone to enable it.
Like i said, the other option is to keep the firmware you have but manually flash a CSC zip file to change the region/country code manually.

Yes you can, or there is a CSC Version 3 for Oreo. file on the forum which contains lots of country codes you can flash with TWRP.

Thanks for helping me out, i am noob at this stuff
How can i change my phone region in a way to fool Samsung keyboard?
I need thst to make Keys Cafe app to work properly in the chinese rom. Must change grom CHC to anywhere else.
I tried flashing a Home_CSC from another region, but the phone gets locked as soon as it boots.
I did flashed CSC from another region with no problems. try to follow the instructions here: https://forum.xda-developers.com/t/...fficial-firmware-noob-friendly.4404283/unread
Tgy, Bri and CHC are your only options.

Do you mean this part?
Optional: If you just want to change CSC, /efi/imei/mps_code.dat is where you can edit after rooting the phone
Replace the CSC you would like to be in the file

So, changing mps_code.dat from another firmware would change the region entirely?
I tried messing with optics/configs/carriers/CHC/conf/customer.xml to change region, but phone got locked, just as it was when flashing the entire Taiwan CSC.
The main reasons I want that is to remove chinese stuff from samsung system apps (keyboard,browser). have you tested this? Would chaning China for Hong Kong or Taiwan solve the problem?
Also, it's possible to make keys cafe work by changing country_code and sales_code and disabling/enabling samsung keyboard.
I just downloaded different region firmware and installed it with odin without any problem.

Yes, this works if you want to change the entire firmware. But did you flash only the CSC to keep rom and change region? When I tried, phone got locked.
I think i wasn't clear in OP. I wanted to change CSC onçy, keeping rom.

This link says that the "make your own keyboard" doesn't work.
It worked by changing country_code and sales_code to USA and XAA
