CSC Selection for SM-G955F/FD/N and SM-G935F/FD/K/L/S/W8 devices (all others untested!)

What is this for?
CSC stands for Country Specific Code, so every single country (and even different providers in one country) have different codes, for csc features, wallpapers, wifi calling, VoLTE, sounds etc. So it is quite important to have the right csc file on your phone for your provider (so you can have all features which comes with your provider (like wifi calling)).
You may ask yourself now, where can this be flashed on? Basically on every stock based rom, as well as on stock roms (who are rooted of course). So: root and a recovery (custom) are required!
Your current country is not listed below? Send me your stock csc file from sammobile.com (SM-G955F variant) and I will add it!

NOTE TO ALL DEVS: You are free to grab any csc you want from this zip, as long as proper credits are given and a link to this thread exist in your OP.

3. Open terminal under advanced tab
4.
Code:
dd if=/data/media/0/EFSBackup/efs.img of=/dev/block/sda3 bs=4096
5. Wait until it's finished
6. Your previous EFS has been restored successfully

Thanks for sharing..
everything works with Tmobile CSC..
only Wifi calling is not working.. it's showing connected, but when calls started it went off..

one quick question, if i remove the EFS partition files, it will automatically generate or end up in NO IMEI/MAC Address..
reason being i flashed mutiple CSC (the files from S7 Edge with little modifications) and got 2 times network locked Sim card detected error. Would like to clean up the EFS partition clean and try the S8 CSC files to check it's Wifi Calling works or not?

Thank you for this.

I had manually copied the ATT CSC over to the phone before I dirty flashed this. WiFi calling would not work at all, but the Enhanced LTE Services was enabled.

I tried to install the US ATT one on an international F model. It seemed to have problems. Not sure if this is normal or not so I thought I would post here.

Code:
Mounting Partitions

mount: failed to mount
/dev/block/platform/111200000.ufs/by-name/HIDDEN-at/preload: Invalid argument
Backing Up EFS...


Installing XAA CSC...
Changing model

unmount of /preload failed: no such volume

Your CSC is successfully installed

Please Reboot now
script suceeded: result was [Please Reboot now]

When I rebooted I got "Upgrading Android..."

After reboot I don't have the AT&T on the right of the Status Bar.

Looking at /efs/imie/mps_code.dat, I have ZTO in there? I expected ATT?

So under settings, I see WiFi calling greyed out. I select it and it comes up and says "Wi-Fi Calling - please try to setup Wi-Fi calling again later." Previously, WiFi Calling in Setup was greyed out. So this is a nice change!

I see Enhanced LTE Services checked! :good:

So I manually edited /efs/imie/mps_code.dat, and changed it to ATT and rebooted. Now I got the death star boot screen. and AT&T on the right of the status bar - at least after initial reboot, but then it disappears :).

But WiFi calling still does not work.

Thank you for this!

Edit:
One other strange thing I noticed is that I replaced the /system/media/shutdown.qmg, bootsamsung.qmg and bootsamsungloop.qmg files with my own boot animation but it keeps using the death start ATT one. So I delete /system/omc/ATT/res and got rid of the death star boot screens!

So, I was in XSA stock ROM and both VoLTE and Wifi Calling was working. Now that I'm on your Rom(BatStock) and after flashing the XSA CSC, I still dont see any options to enable them?
Am I missing something here?
What does it show in the menu?
Does it show XAS active?

That error from script is normal. I found out that the preload partition does only exist on S8+ models so all s8 users will get that mount log, but it's not important since it's not used after all.

For ATT, I need you guys to help me out here, I don't live in the US, I don't have a ATT sim or whatever so I just started where we ended on the s7.
That was:
Original CSC needs to be ZTO, otherwise imsservice would constantly crash (this is maybe obsolent now?)
Anyway I'm open for all your suggestions as you are a proper ATT user!

Thank you for your work and for the quick reply. I would be happy to help. I am not seeing any crashes at all, and none for the imsservice. I see ims service 1.0 installed but I don't know if I am using it. Changing /efs/imie/mps_code.dat to ATT did not seem to cause any crashes - at least for me on the S8+ model F.

One other question to ask. Is there a recommended way to remove the carrier label on the left side of the status bar?

Not sure the 1.8 files will write mps_code.dat as TMB, the latest ZIP will flash mps_code.dat as ZTO only for all US variants..

if i go and overwrite the mps_code.dat as TMB and reboot, i can see the Tmobile Boot logo.. but Wifi calling is still wonky.. need do a clean flash and test it.. will wait for BATSTOCK next update to proceed further.


What about Video Calling & VoLTE? I only use Video Calling & VoLTE (rarely use WiFi Calling)

Thank You!

VoLTE works.. will give information about VideoCall when you open the dialer.. but i haven't used it.

Regarding ATT in the US. I had to call customer service and the nice lady said that their system would not accept the IMEI of my new S8 + since it was not a phone from ATT. I gave her the new IMEI and their system would not accept it. She ended up using the IMEI of an ATT S7 we had on the account and then Volte seemed to start working. I see Video calling is now also working :).

I still cannot get WiFi calling to work - meaning when I try to enable it in settings, it sits for a minute and then says try again later. It will not enable wifi calling.

We can help to our extent..
I overrides the mps code with TMB but no crashes and I got the Tmobile boot logo...

Volte works (even if i modify the Csc of other region also it works).. WiFi calling says connected.. But not works.
If i select use only WiFi for calling, signal is cut off.. But calling not going through.. Says out of service area.. In the dialing screen..

Okay great so this workaround from the S7 is not needed anymore. I will delete my additional code concerning this than, thanks for the report!
For wifi calling, I'm pretty sure we will find the cause for this problem and error it out as well!

And about the carrier on statusbar:
Can be edited in: system/omc/ATT/cscfeature.xml

Can you get a log during the time you tried to connect to wifi calling?
Would be great to see!

    So, I was in XSA stock ROM and both VoLTE and Wifi Calling was working. Now that I'm on your Rom(BatStock) and after flashing the XSA CSC, I still dont see any options to enable them?
    Am I missing something here?
    What does it show in the menu?
    Does it show XAS active?
    Thank you for this.

    I had manually copied the ATT CSC over to the phone before I dirty flashed this. WiFi calling would not work at all, but the Enhanced LTE Services was enabled.

    I tried to install the US ATT one on an international F model. It seemed to have problems. Not sure if this is normal or not so I thought I would post here.

    When I rebooted I got "Upgrading Android..."

    After reboot I don't have the AT&T on the right of the Status Bar.

    Looking at /efs/imie/mps_code.dat, I have ZTO in there? I expected ATT?

    So under settings, I see WiFi calling greyed out. I select it and it comes up and says "Wi-Fi Calling - please try to setup Wi-Fi calling again later." Previously, WiFi Calling in Setup was greyed out. So this is a nice change!

    I see Enhanced LTE Services checked! :good:

    So I manually edited /efs/imie/mps_code.dat, and changed it to ATT and rebooted. Now I got the death star boot screen. and AT&T on the right of the status bar - at least after initial reboot, but then it disappears :).

    But WiFi calling still does not work.

    Thank you for this!

    Edit:
    One other strange thing I noticed is that I replaced the /system/media/shutdown.qmg, bootsamsung.qmg and bootsamsungloop.qmg files with my own boot animation but it keeps using the death start ATT one. So I delete /system/omc/ATT/res and got rid of the death star boot screens!
    That error from script is normal. I found out that the preload partition does only exist on S8+ models so all s8 users will get that mount log, but it's not important since it's not used after all.

    For ATT, I need you guys to help me out here, I don't live in the US, I don't have a ATT sim or whatever so I just started where we ended on the s7.
    That was:
    Original CSC needs to be ZTO, otherwise imsservice would constantly crash (this is maybe obsolent now?)
    Anyway I'm open for all your suggestions as you are a proper ATT user!
