My phone came with carrier bloat (splash screen and all)
The only method that I found that would work was Samkey so I paid up and changed my CSC to BTU.
My service provider details are now
SAOMC_SM-N986B_OXM_BTU_RR_0007
BTU/BTU,BTU/EUX/H3G
Do I need to do anything else to start getting my updates straight from Samsung?
Thank you

A little history on how I get to no VoLTE and my question: I'm trying to figure out if there is a way to copy 'some' CSC directory files, or modify a CSC file to enable the VoLTE tab to show and work?
So I have a G930S phone with 8+ Infinity v8 ROM. Phone INFO and CSC Features apps shows phone as G955F, with a CSC code of XAA, USA/US. The phone works just fine on the AT&T service, even without doing a scan of "Service Providers". Interestingly, there is no CSC directory in root/System. There is no VoLTE, as I'd think is consistent with the original phone being G930S (Korean)
I can go into Settings/Connection/Mobile Networks/Network Operators and do a scan of providers and it pulls up AT&T, T-Mobile, etc just fine. That's great.
I think because the base phone is for the China area, when I go into the Settings/Connection/Data Usage area, going into the "Service provider settings", I get three Chinese possible servers, and when I go into "Region", there is a list of Chinese cities. I do lose these Chinese setting tabs when I flash a US based CSC.
I have flashed CSC TMB, ATT and XAA, and the phone works fine on the AT&T service (Cricket) , and a specific System/CSC directory is installed, though I can no longer input any phone 'codes', eg *# whatever. I've tried about 5 methods to get the phone to get working *# codes, nothing so far solves it.
I have tried copying into System a CSC directory for ATT and later TMB or XAA, and my setup will work fine on the AT&T service, and I lose the Chinese regions/cities, as should be appropriate, but I can not input any phone codes, *#...
So I've gone back to the 8+ ROM, where there is no System/CSC directory and I get AT&T service with or without doing a Service provider search, but no VoLTE.
I'm trying to figure out if there is a way to copy 'some' CSC directory files, or modify a CSC file to enable the VoLTE tab to show and work?
I found out this week during the fire storms in southern California my unlocked SM-G930F doesn't receive any of these emergency messages. In fact, all references on how to turn them on/off lead you to either the Messages App or Settings of which the option to turn/off isn't there. Of course, the phone only a year old and bought through Amazon so that I can have an unlocked phone is not supported by Samsung. Oh what a surprise?
I didn't want to upload all new firmware, just an app that wil allow the option to turn them on/off or gate me to the feature. The assumption here is that Samsung makes bricks in the S7 variety that are designated by either the modulation hardware(cdma/gsm/tdma) and the firmware to support it. The rest would be just application??? Hence a GSM phone is a brick and the OS is specifically written for large carriers and or specific regions are transferred on pushes.
Is there anything out here that will enable the WEA on the phone?
I would assume WEA comes through the carrier, which means you'd need to flash the CSC for your carrier (assuming you haven't already). Since the G930F is an international model, if you bought it directly from Samsung and never added your own carrier settings to it, I don't think it would know to relay emergency messages.
There's a flashable zip with CSC's in the development section
I have the US Unlocked S7 and the option to identify spam callers is grayed out
Anyone know why/how to enable it
Some carriers run their own spam caller service you have to pay extra for, and disable the functionality in their phones to make you pay. Is yours running the G930U firmware and CSC?
Even if it has been unlocked, it could still be running the carrier specific firmware
Yes I am running G930U firware and CSC and I doubt it would be due to my carrier as I am in Trinidad on Digicel

CSC Value cant be just XAA. It should be something like ***/***/XAA so give the correct CSC and also check the bands on which your Carrier is broadcasting 5G. Who is your carrier / servce provider, Sunrise?
You have to reset your CSC to your home provider in order to get 5G.
Try this: Goto Settings, then About Phone. Write down your IMEI number. Open the dialer and enter *#272*IMEInumber# then press Dial, you should see a screen with the list of available CSC codes for your device. Select the CSC for your carrier (hopefully it is listed) and then tap install. It should not do a factory reset but if you have important data, you might want to back up your phone first. Post if this works for you. This works in Canada if you buy a phone from one carrier and switch to another.

Are you sure your bands are effective for your country?
I believe the usa device's are Snapdragon based and the eu versions are Exynos.
Somewhere I've seen a message with this 'same' band problems due to this difference. I'm not sure if this is still a difference. Please compare band channels.
Forgive me if this has been covered but I havn't found the answer. I've flashed just about every phone I've ever had but my question here is can I / how do I flash to where the phone reads as XAA in download Mode?
The situation is my phone was originally on at&t. They unlocked it and I'm on Verizon. It all works great (it still says at&t on download Mode screen)
My problem is that if I log into the my Verizon app it disables my visual voicemail. I finally got a Verizon tech on the phone that explained that it is unsupported due to originally being on a different carrier and their system identifies that and disables the VVM. The only fix I can find is to put my sim in my backup S9+ that came from Samsung unlocked (or any Verizon phone) and I can then reactivate my VVM by resubscribing.
I currently have 3 Note 20 Ultras. One Each originally from Samsung, ATT and Verizon but the AT&T is the only one that is 512GB or I would just switch phones. I have flashed them all to U1 firmware but notice they all still reflect the original carrier in Download Mode so again my question is can I change this by flashing it / or is it just a matter of what sim card is in it when it's flashed? I need it to be seen as XAA by Verizon system so not to loose VVM... Pics attached.
Any advice here is greatly appreciated in advance.
Just a try... You can try the *#272*imei# method... But thats If it works. Not sure if the sims has to be in the phone for that to work.

Yes it brings up this menu... So I just select the XAA and that's it? I've been reading forums and this method is reversible it seems ... I'm familiar with Odin and all that but these hidden menus are new to me...
Thanks for the reply btw
You may have to activate the bottom most option to stay.
Don't worry if you can't access the menu after the change. You can download samsung band selection and change to automatic or one of the lte options then back to automatic to get to the menu.
CSC Guide
CSC (which I think means Carrier Service Code) helps to set what options for settings show in the device for things like voicemail and wifi calling, as well as sets network code information for things like carrier aggregation combos.
When you go to your phone settings->about phone->software information and look in the Service Provider SW ver. section, you will see as the last line a combo like XXX/YYY/ZZZ. This indicates what carrier sales and network code is set and what brand the phone was manufactured as.
I think of the XXX/YYY/ZZZ configuration as follows
XXX=Sales Code-What kind of features are setup in the firmware like wifi calling, video calling and settings menus
YYY=Network Code-What kind of network features are set for things like carrier aggregation and LTE/5G bands
ZZZ=Manufactured as Code- What model the phone was originally manufactured as. Ot has no affect on the system settings or options. THIS CAN NOT CHANGE. IT SHOULD ALWAYS BE THE SAME. ONLY A ROOTED PHONE WOULD BE ABLE TO ACCESS THE FILES NECESSARY TO CHANGE THIS.
