Need CSC files from US T-Mobile Galaxy S7

[vzaliva]

Hi! I am investigating how to enable Wi-Fi calling with T-mobile SIM on non-T-mobile branded (generic) Galaxy S7. I narrowed it down to settings in a few system files. I need a copy of these files from Somebody who has US T-mobile Galaxy S7. Basically I am looking for all xml files located under /features/csc/. On my phone they are are others.xml and customer.xml.

I will appreciate if somebody could fetch these files and post/send it to me. If I manage to make this work the results will be of benefit to the whole community.

1. Enable USB debugging ( no need to root or modify your phone in any way)
2. Install adb (instructions)
3. Execute the following commands:

  adb pull /system/csc/customer.xml
  adb pull /system/csc/others.xml

4. Post here or send me directly these files.

Thanks!

Thanks! Also please confirm that you see the option in Settings to enable Wi-Fi calling.
Like shown in attached image.

I am more interested in WiFi calling but VoLTE options seems to be managed in the same way. If we find solution to enable one, other will follow for sure.

The first glance at XML files is little discouraging. They look very different from ones I have on generic model. On generic model I have WiFi calling options seems to be limited to certain operators, and I thought all I need is to add T-mobile US to this list. Apparently G930T firmware is different. I will be experimenting with it more and will post updates.

Wow, if you can get this to work, this would be a satisfactory solution to me. I will not buy a phone that's not rootable, but if an Exynos version can get all the T-Mobile goodies, I'm sold. Good luck!

Not sure if it sways anyone's decision but T-Mobile announced more enhanced calling stuff this week which would be more features not available on the intl

I wanted to report back my results. It looks like T-mobile firmware substantially different from others and config files do not match.
One thing I tried is to add US T-mobile networks from T-mobile CSC files to list of network which allow Wi-Fi calling in EE firmware CSC files. This did not help.

Do you think a T-mobile S6 Marshmallow will help? the S6 having an exynos processor may make it's CSC more in line with the S7 International

I tried German T-Mobile firmware, and it did not help either.

How will you push the new CSC files without root?

 

[GbizzleMcGrizzle]

Are those csc could from an exnyos phone?

Any progress? Vzaliva?

It wont work im almost 100% the kernel needs to be modded or a tmobile kernel used.

I'm new to this, but is it possible to get T-Mobile WiFi-Calling & VoLTE on Hong Kong variant S7/ edge? They both have snapdragon processors, but the hong kong one is bootloader unlockable.

Here a t-mobile flashable csc throught recovery, for s7. I tested on my sm-g930f. No volte, no wifi callings, hd voice etc.
