Hi guys,
just bought a new Samsung Galaxy S7 (SM-G930F).
Of course I got it with the Android 6.0.1 but I want to upgrade it to 7.
As for now, my build has no OTA updates to 7, but I saw that there's a UK build for Android 7.
Question is... if my build number is G930FXXU1BPLB, can I upgrade it to other build number, as for example to: G930FXXU1DPLT ?
And.. if I can do that... Will I get OTA updates of the future releases? It's important to note that I live in Israel, so what happens if I Install an UK build?
Will it block me to get OTA updates because I'm not from the region?
Thanks!
Everything works, except WifiCalling and VoLTE, if you switch to a british firmware.
So OTA's and the like won't be a problem. It's the same experience as if you were using your current german firmware in Israel.
For OTA's be sure to use the correct CSC file, so it get's changed aswell. DBT/BTU mix stuff won't get you OTA's
Given that i had a problem with restoring WhatsApp's chatlog when switching from 6.0 to 7.0 (which according to google and a post here, i'm the only one to have it), it's still advised to read up on app compatibility.
Also it's advised to do a factory reset after flashing, so everything is reset.

Thanks,
So I understand you won't any problems. And I don't really need the WiFi calling.
But about the VoLTE, do you mean that I'll loose the 4G ? Or do you something else?
About the CSC, I have to admit that I don't really know what it is. Is it a file that comes with the files that I should flash?
About the build number, I've just saw that there's a newer build of UK according to sammobile website: G930FXXU1DQB3 (released on the 06/02/2017), and the G930FXXU1DPLT (released on 16/01/2017) that I've stated in the original topic.
Is there a difference between them, should I go with the G930FXXU1DQB3 ?
Thanks again.

VoLTE is the "new" standard for calling.
Normally, when you call someone and don't use VoLTE, you fall back to the local 2G/3G network, which is slower and has lesser quality. Since many providers, atleast in my country, haven't completely switched over (for example prepaid customers still have the outdated 2G/3G calling), you should not notice much of a difference, since it's the same call quality as in 2013 for example. You will still understand people, as they will understand you.
4G / LTE data connectivity is unaffected by it and works without any problems, regardless of country etc. , unless you travel to america and use a local providers sim card there, where you might need the Snapdragon variant of the S7.
That being said, i flashed the newest firmware (DQB3) and it works flawlessly, except afromentioned WhatsApp problem. The only difference is, the update dated to the end of january is included, which fixes some stuff.
A CSC file contains country specific settings, like frequencies used, APN's and even carrier brandings are found in this file, which is why they might differ in size for different regions/carriers.
Because of that, VoLTE and wifi calling might not work, since, in this case, they use the BTU networks standard and you are not in the UK but Israel, aswell as probably not using a british provider.
Anyways back to your question:
There are 2 CSC files, the ROM`s CSC one and a HOME_CSC.
To receive OTA's, you will need to flash the normal CSC and not the HOME one. This will reset and wipe your device (backup all important stuff beforehand) and you get a device "fresh out of the box" bought in the UK.
The HOME CSC does not wipe your memory, but you won't receive OTA updates aswell, since your device hasn't changed it CSC and thus "is not an original BTU device".
So if you go down that route, which is perfectly acceptable and should not make any problems, you will have to flash updates manually via Odin.

Are those the only options I need to check & load in Odin for flashing the new ROM?
Because I have few more files in the folder like BL and CP.

Hi ahi,
I live in Israel too and flashed the UK firmware on my s7.
I install everything that was packed in the rar you download.
Nougat is awesome for our phone.

Select everything. Bootloader is very important for example. Otherwise you most likely will brick your phone
Anyways enjoy Nougat, i'm actually doing the same process again now, to see if i can get my WA Backup to work somehow.

Very nice, good to know that it works for you.
Currently doing a downgrade with full wipe to 6.0.1 and then update via OTA. Let's see if that fixes it. Otherwise i have to start clean
Anyways, again enjoy Nougat. Should run very good out of the box

Guys, what about Samsung Pay and Android Pay? Are they working fine? I am on XSA. Australia has Samsung pay and Android Pay working.

Just a question can some confirm if using stock Samsung browser when keyboard comes up but prodictive text don't work. But when using chrome it works?
I've got a question too. I would like to change my 6.0.1 on 7.0, also British stuff but I'm a little bit concerned about mixing XEO and BTU. Is it possible to mix 6.0.1 HOME_CSC XEO (latest) with 7.0 British BTU + PIT file from the 7.0 BTU Home (I would like to make factory reset and have my native CSC file)? Does it make difference to take PIT file from 6.0.1 or 7.0 Home file either?

For Samsung Pay, i can't confirm, but since Android Pay definitely works, Samsung Pay should work aswell, if you did not trigger Knox etc.

You can mix it, but personally, i advice against it. Might reduce battery life, you will have to flash every update manually, since OTA does not work with a mix of XEO/BTU.
Also, since XEO and BTU share a common CSC file (they are OXA's, multipurpose CSC's) in most nougat roms around, you might need to root anyway to completely switch over, if a repartition + factory / cache reset won't work.
So to summarize, yes it's possible to use the HOME_CSC to avoid switching your CSC and wiping your phone. It's also possible to stay on a 6.0.1 CSC, but! there might be problems later.
If possible always do a fresh install and if your phone runs well currently, why not stay on Marshmallow? Depending on the current OTA release, which you might have to look up for your country, it might be better to wait a bit. Personally for me, it'd be a complete switch over, since i am too lazy to flash every update manually.
That being said, you won't need a PIT file going from 6.0.1 to 7.0, since it is included in the CSC. Pit files might be useful, if you want to downgrade and in some other cases, but not if you just want to upgrade. They include repartition infos, which are important, if you don't have a "4 file flash" (yucks, my english for explaining it better, sorry).

Yeah, but that wouldn't be a problem for me, cuz I've been using custom ROMs manual flashing on my old fellow Galaxy S4, whenever update was avaiable but anyway, who doesn't want to make things easier?

Samsung consultant said to me that they EVEN DON'T KNOW when 7.0 will be relased for our country. That made me angry and I said to myself that I will take the matters into one’s own hands.

Sorry for the late reply, work called.
Usually a BTU won't draw more battery or anything, since frequencies mostly are standard in every country. It's more like saved APN's etc. (which you can change manually via your phone's settings menu anyways). But as previously mentioned to the original poster, you can depending on where you live, loose out on VoLTE and Wifi-Calling, since those a carrier specific and usually not included in an unbranded ROM. If those are important to you, you probably want to stick with your current ROM, even if i do understand that new things are always fun. Even i did not wait for my carrier..
But having OTA updates and stuff like that is convenient, otherwise you'd have to flash every update like this one, which is why i recommend using a full BTU firmware, if you really wanna do it. Well, you don't have to flash it manually.. but it won't change since OTA updates are CSC based. So for example if Android 7.1 or another security patch will come out, you will need to wait until your XEO (Poland, i presume?) firmware get's the corresponding update, which according to you might take ages, since the original Nougat is not even out yet.
If you only have an AP file, i recommend using updato.com / samfirmware to download the current image of the BTU. Since you will need Bootloader and Modem files aswell (BL, CP respectively), aswell as the CSC file. I have checked though, your current CSC is included in the OXA (multipurpose CSC) of the BTU. So you might wanna flash a non BTU image first to change the CSC to something not included in the BTU one. Otherwise you will need root access to change it manually and this triggers Knox as we all know and thus your warranty is gone. And if you flash a non BTU image, be sure to factory reset / clear cache via recovery mode after installing and then let it boot normally, so the CSC change will take effect, afterwards flash the BTU image will all files and do the same. Be sure to backup your data beforehand, since they will get lost and do NOT use the HOME_CSC file. This one is for not changing the CSC at all and will retain your data. Use the ROM's CSC. Also always check the rom for your model, i have seen people who used a 935F (which is the edge) ROM on a flat S7 (which is 930F in europe mostly). But that's why i highlight it.
If you have further questions, i'll answer them to the best of my abilities
Oh and i almost forgot, you don't need a pit file . It's really just for more engineerical purposes as explained in ODIN. Current Marshmallow and Nougat Roms consist of 4 parts, which include the corresponding PIT.
I highly recommend not using the PIT file, if you don't know what it entails (you will need to look on the internet for it, since it will be quite lengthy if i explain). In short, as long as an update does not use a different partition layout and / or you mess up your partitions by yourself, you just don't need it. And doing afromentioned, would require extensive knowledge about Android anyways. As long as you don't root and modify your system yourself, you most likely will always be fine. And since rooting does have it's drawback (like some Apps not working due to security, Samsung warranty void etc), i'd not recommend it anyways, unless you are experienced

I have used the PIT file when I was debranding, that is why I was asking about extended purposes Obviously, I haven't got extensive knowledge about android but I know just the basics (the reason why it looks like that is I am not programming anything, otherwise I would know more, much more).
And, using occasion... Since S7 ownership I was wondering how root would affect function "safe start". Would it be possible to bypass this function COMPLETELY after launch, on the rooted phone (For example: if someone could steal it and unluckily, had extensive android knowledge could bypass launch/start password, and, the worst, security lock, when my phone is fully rooted)?

Hi everyone
What's the best way to change my CSC to BTU (from EVR)?
I've done a little research and found the following:
1. Root using PingPong to prevent KNOX trip
2. change CSC using an app (is this available for S6 in the app store?)
3. flash with BTU firmware and unroot
Is any of this possible, is there a better way?
thank you.
Yes, its possible while your still on 5.0.2.

Thanks roydok, whats the best app in the store to make the change as there are so many to choose from?
Also is there a simpler way, or is the way i described it the only option, esp for KNOX trip?
I've seen some other tutorials use the auto cf root way, is that ok to use or does that trip KNOX?
Lastly, if i move to BTU and update to 5.1.1 will i continue to get OTA updates direct from Samsung rather than my carrier?
thank you.

As far as I am aware.. your csc will change by flashing btu... your root obviously be gone too. If you flash 5
1.1 you loose root but you'll gain ota from samsung rather than your carrier. Hope that helps
Skip the rooting and just flash the btu firmware from Odin. That will change your CSC anyway.
I was on vau firmware but changed to xsa using this method.
Just be sure the btu firmware us for the same variant of fallacy s6 as your device (I.e both 920F or whatever you're rocking)
EDIT
To get btu system updates going forward you WILL need to factory reset after flashing the btu firmware as your device needs to re-register with that CSC. There might be a way to force it to do that without a factory reset but I dunno how. So perhaps use smart switch or Helium (from app store) to backup whatever is important to you first

SSTIWARI's reply in the following post scared me http://forum.xda-developers.com/gal...ock-rom-via-odin-affect-t3138019#post61992036
His Knox tripped when using a standard BTU ROM from sammobile and flashing via Odin 3.10.6, it sounds risky.
So going back to my original post, would that order of doing seem the safest? Would it even work? Still not sure which app to use to change the CSC.

Strange. Everything else I've seen on here and other for UK mobile s suggest that flashing stock roms with Odin is safe and doesn't trip Knox. My own experience confirms that also. But I used the xsa firmware as I've the 925I variant so maybe it's different. Seems odd though. What about other people who have flashed btu firmware? Is his an isolated incident?

The reason you have to wipe/factory reset is so that your device registers with Samsung for updates against the new CSC. It was previously registered against the old CSC so won't get update notifications for the new one unless you do. At least, that's what I had to do to get XSA updates pushed to my (previously VAU CSC) phone. It's been confirmed by a number of other users over on whirlpool forums (Australian tech forum).
If there's another way to register the device then I don't know what it is
How did I restore? Well, I used Helium to do the back up of app data and sms's etc, so just restored via helium. Discovered Smart Switch backups afterwards but I've never used it myself so can't comment.
Hi there XDA,
First of all, I don't claim to be a developer nor I am here to plagiarize/steal/uncredit those developers and providers.
Therefore, this post is to provide you with the latest UNLOCKED SM-G935U Stock Firmware for
users running the T-MOBILE variant (SM-G935T)
There were many comments on threads as to when the firmware would update, and finally is here!
Note: I DO NOT TAKE CREDIT FOR THIS, I DID NOT CREATE THIS OR STOLE FROM ANYBODY. THE INFORMATION PROVIDED LINKS DIRECTLY TO SAMSUNG's OFFICIAL FIRMWARE WEBSITE "SAMMOBILE".
Note to the Community: This latest version is confirmed to have ISSUES with ROOT. After successful root and/or XPOSED, Wi-Fi connection, overall lag, and heating issues are present. So it is up to you if you decide to root or not.
Note to Admin/Moderators: IF YOU FEEL THIS THREAD IS NOT APPROPIATE OR IF YOU WANT TO ELIMINATE THIS THREAD, FEEL FREE TO DO IT. My intention is just to provide the community with this update for the SM-G935U (T-MOBILE) Firmware as quick as possible for those in need and for those pioneering fellas.
As soon as I am done setting up, I will surely provide you with any insight/features added to this update.
Happy developing...
RECENT UPDATES ON ROOT PERFORMANCE/STABILITY [Jan.30.2017]: This 4APL4 Variant INDEED works with the root method by @Mastajeff, I can't find any issues at all. I personally believe that this Firmware version without root works even better for whatever your needs.
*** BASED ON PERSONAL USE AND RECENT DOWNGRADE TO STOCK G935U###4API3, I ENDED UP HAVING BETTER PERFORMANCE, BATTERY LIFE, AND STABILITY WITHOUT ROOT. I JUST WENT ON TO DISABLE COUPLE SYSTEM APPS WITH EZ DISABLER. I NOTICED BETTER RESULTS, PERFORMANCE, AND STABILITY USING ROOT ON THE PREVIOUS #4API3 FIRMWARE VERSION. (THIS IS JUST MY OPINION BASED ON RECENT UPDATE I DID, BUT IT IS ALWAYS YOUR CHOICE TO WORK ON)

What is the difference with features of this G935UUEU4APL4 Frimware and G935TUVU4APK1?
I am on previous U firmware API3. Is there a way to upgrade to this without losing data?
Thanks,
Hello my friend, of course you can upgrade without losing data.
But I have a quick note for you, if you have a micro sd card will make everything better.
But if you don't, just upgrade using latest Odin version v3.12 by flashing THE BL, AP, CP......AND MOST IMPORTANT THE CSC FILE....Don't flash the HOME_CSC. You won't lose anything at all my friend.

Can anyone who's flashed this confirm if the modem works with band 12, or if we still need to use the TMO apk3 modem?

As a matter of fact, T-Mobile's SM-G935T also released an APL4 Firmware update.
So we are better off flashing the latest CP File from SM-G935T into the G935U APL4 Firmware.
*will provide links to all downloads*

Hello there pal,
I've sucessfully flashed this update and the VERY FIRST THING I NOTICED is a SMOOTHER UI. During the setup I noticed an increase in speed and touch response.
Samsung Pay comes in by default and it can't be disabled by default. Other than that, the ONLY down I noticed....AND I MIGHT BE WRONG GUYS BUT....I am actually surprised to notice significant battery drain
Have you personally went on to flash this update??

I was on API3 I went to setting and clicked on system update and it updated to APL4. If you are using G935T CP modem you might to flash the API3 modem in CP to get the update. and you should not loose any data.

Perhaps quarkw something was not or was checked that caused the pit to partition your puppy with Odin. When you flash via Odin from one one rom to another there is always a chance of losing data.
Once you wipe cache in the recovery step (if you did this step) there were some other options that may have wipe the phone or your MicroSD card.
The files may actually be present and you may have lost root, if you had it. There are so many variables that could have happened.
It sucks to loose data, it does.
But look at it as a learning experience and make the time to perform the following steps next time.
If I were you, get root then get TI backup over at google play (get the paid version) to backup everything to your MicroSD that way you can always flash without losing data.
TIP: save your present contacts with their phone numbers, email address & address to Google Contacts, so whenever you flash and format, your contacts will be there automatically with you once you sign into your Google Account.
Perhaps I may write a tutorial on how to flash / backup rom & data APKs and such. It took me a while to learn the ropes too.
I'm pretty sure you flash the HOME CSC file if you DON'T want to lose all your data, thats what I've read else where here on xda

Yes if you were using the G935T CP modem you do have to flash the API3 modem in the CP section of Odin to get the OTA update for APL4. I didn't lose any data doing this.
Also I could have sworn I could still use Wifi Calling on the API3 firmware. But I definitely can't on APL4. Can anyone confirm if you do have wifi calling with the API3 firmware with the US unlocked modem or API3 firmware with the T-Mobile APK1 CP modem?

I have korean S7 G930L, and are having some questions:
-(I'm NOT looking for troubleshooting, just want to know if anyone have the same problem) I still don't know why, but I tried many Nougat custom ROMs (Touchwiz based, like Batman, Superman...) and kernels for my G930L, things work fine, except for the back and recent touch button NOT working (press it, no response, no backlight or vibrate). I tried all kind of setting inside the rom, using button remap app, no good. Only way for them to work again is to flash back to stock firmware through Odin. Even if I just flash the custom kernel over the stock firmware those button stop working right after that. So anyone having korean S7 model, do you have the same problem as me? I've posted the issue on the rom forum, but seem like there won't be any fix now.
-Since F/FD model also are Exynos variant, I was hoping I could flash F/FD firmware through Odin to my L, but maybe it's not possible (too afraid of bricking my phone to try). I read somewhere that's because of the different partition size, and I don't know if re-partition option in Odin can help, because that maybe unsafe to do so. Your opinions?
-I also read that you can replace the CSC file with your country CSC file when flashing, while load the BL, AP, CP file of the current model. Can I do that? I also read that I have to tick the re-partition box in Odin, and my fear of bricking my phone stop me from doing so, because my country sold the FD model and I'm having L model, if I also have F/FD model then I would have gave it a try.
Only thing I can think of is if you selected on screen buttons when installing the ROM. Those will disable hardware buttons.
Not sure about 930F/D compatibility with S/L/K
As for Odin, I've always read that you leave all options default and don't manually check/uncheck anything. You should be able to flash whatever CSC you want so long its CSC within your models variant, but again not sure with 930F/D compatibility. There is a flashable CSC utility that supports S/L/K you can do after the fact: https://forum.xda-developers.com/galaxy-s7/development/utility-flashable-csc-selection-30-t3392949

Do you have Korean S7? I want to know if it's a common problem with korean model or is it just me who have it.
For S8 ported ROM, I'm sure I uncheck the on-screen button first, but those buttons didn't work. It also happen with S7 stock-based ROM like Superman, or even just flash another custom kernel over the stock ROM, all the time the same problem.
I'm currently using the CSC selection and it works fine, but it also means I have to root the phone. I want a way that I don't have to root but can use CSC feature, so I can have OTA update or apps that require unrooted phone to use. It's clear that using custom ROM or kernel are the easiest way but not an option for me.
I'm on a 930F. Sounds like there must be a difference with the S/L/K buttons that F/D ROM's don't account for, can't think of anything else.
I would guess flashing CSC should be fine on any Exynos variant, but that's just a guess. I've got nothing tangible to base that on. I also imagine worst case scenario you'd still be able to get into download mode and flash again if it goes wrong.
Have you tried Marshmallow? Just to see if it works?

Don't know if I can downgrade to Marshmallow (I remember I've read that it's not possible), but for now I want to stick with Nougat. That's why I want to hear opinions of another Korean model users and how they deal with the problem.
I've gone between N and MM and back a few times waiting for Xposed N
So long as you flash all 4 files that belong to MM with Odin it's fine. You just shouldn't flash a zip to downgrade, since that's doesn't downgrade everything and will cause problems.

Good to know that. Maybe someday I'll give it a try. But if I can have Nougat ROM without problems like those it would be best. Those Korean model have limited SMS length, and cannot mute camera shutter sound which pretty annoying, not to mention those bloatware. And my phone have already tripped Knox, or else I might just live with it and stay stock.

Hey buddy. I am also very much thinking of the re-partition thing. Do not have the courage to brick my phone. Have you done anything since the post is quite old.
Hi all
I just purchased the International S8+ dual Sim variant, the G955FD, from eBay.
I live in Canada and will be using both a Telus Sim and a Rogers Sim.
Is there anything I need to worry about regarding the CSC type?
I found this thread, https://forum.xda-developers.com/ga...ility-flashable-csc-selection-v1-0-0-t3605264
So it seems easy enough - I just don't know if and when I need to change the type.
And should I even be changing it to Telus or Rogers, since they don't have this variant?
And yes this is my first Samsung phone
And input is appreciated!
Edit: if it matters, I don't use wifi calling for either Telus or Rogers. I also plan on simply rooting the phone with magisk to make some mods, and put on Android pay
Just curious. Where was your Duos sourced from?

Great question.
As I did more reading on the device I checked the eBay listing and didn't see exactly where it's sourced from. I should have it in hand by Wednesday and I'll try to validate then. What should I be looking for?
Is there a specific source country that works better than others?

Firstly, congratulations on the new phone. I've got a 955FD as well.
It doesn't matter where the phone is sourced from, although if you want to check, you can go in to settings > about > software information > service provider information and see the CSCs listed there, in this format 'XXX/XXX/XXX'
The first one is the active CSC on the device at the time of you checking, the second one is the CSC for the SIM card currently being used, and the third CSC which can not be changed at ALL is the one from which country the device was sourced.
I'm in Pakistan so for me the CSC format is: PAK/PAK/MID
First two are PAK because that's the CSC for my SIM card and because it's the active CSC on my device, however the last one always remains as MID since that's where my device was imported from.
Canada has no CSCs available for the G955FD sicne it's the Exynos variant and the one sold in Canda is the G955W which is Single SIM and SD835, however the CSCs should work regardless of device variant. You can flash the CSC for whichever is your main SIM card, or whichever you use more often. Either Telus or Rogers, entirely up to you.
The benefits of flashing your carriers CSC is getting stuff like VoLTE and WiFi calling (and sometimes even 4G+/LTE+) to work. No harm in doing it since you're going to root anyway, so make sure to flash whichever one you prefer.
Magisk, rooting, mods, that's all fine, but do confirm properly about Android Pay before actually going ahead and rooting.
Samsung Pay will not work in Canada with the 955FD, and will definitely not work anywhere at all once you've rooted and tripped the KNOX warranty counter. Android Pay can be tricked into working by passing SafetyNet with Magisk, not sure if this still works or not though.
Other than that you should't have any issues.
If you've got any more questions, just tag me or quote this post and I'll be happy to help.

Thank you!
The break down is very much appreciated.
Is there any issue with flashing (via TWRP or Odin?) random CSCs?
Since there is no G955FD in Canada, I don't want to break anything.
I'm very comfortable with flashing and modding the heck out of Android phones, but Samsung seems to be a totally different ball game lol
I obtained a Galaxy S8+ G955FD Dual Sim from e-Bay as well, sourced from UAE. I was able to register US issued MasterCard and Visa on Samsung Pay.
I am on T-Mobile, other than not having WIFI calling, the G955FD works great. Rooting the phone would most likely break the Samsung Pay. So that is a decision you need to make.

No issues at all. Plenty of people in the US using the Exynos variants and they've all flashed the necessary CSCs when required.
Flash TWRP using Odin and then use the flashable CSC selection mod to choose whatever CSC you'd like to flash.

I'll assume that flashing TWRP is going to trip knox, right? therefore flashing a localized CSC is going to require me tripping knox.
Which hey, if Android Pay works fine then i don't need to use Samsung Pay i guess.
If i dont change my CSC, then will my phone receive OTAs when they're released in whatever country its sourced from?
Will changing my CSC to a Canadian one mean i'll start seeing Canadian OTAs?
What about manually flashing official images? Do i have to make sure that the file i'm using matches the CSC as well?
And lastly, are the S8 and S8+ images the same file? Or are ROMs for the S8 100% compatible with the S8+?

Flashing anything other than a Samsung Stock ROM will trip KNOX. Including TWRP. The Canadian CSC using the flashable CSC selector will have no effect on KNOX since it'll already have been tripped because of TWRP.
If you don't change your CSC, and are rooted with Magisk and have mods, you won't get any OTAs since the phone is rooted.
And no, changing to a Canadian CSC will not get you Canadian OTAs since the Canadian variant has the Snapdragon 835 and the 955FD you're getting has an Exynos 8895, so OTAs and stock ROMs are most definitely not interchangeable.
Manually flashing stock ROMs is possible, I suggest you flash the newest one available when you get the phone, which is G955FXXU1AQK7. And honestly, because there's been a major overhaul in how CSCs work on the S8, you can just grab any firmware and flash it and it'll stay on the CSC your phone came from because it can't switch to a Canadian one without you manually doing it.
S8/S8+ images are not the same and you can't flash S8 images on an S8+ or S8+ images on an S8.
Only S8+ (G955F/G955FD) stock ROMs will work on your phone.
However, since you're going through all the effort to root, change CSC and flash Magisk Mods, might as well use a custom ROM?
They get updated regularly so you don't have to keep flashing the stock ROM, and you can still have root, CSC mods and everything but with a few extra features and possibly better performance.

I got my S8+ over Thanksgiving and have been using this for less than 2 weeks. I received an OTA update a few days ago. It was an Android security patch dated November 1, 2017. So, I am getting security patch updates.

So maybe the first think i do is try and see how long i can go without having to root it / put on TWRP.
If i dont touch anything, including the CSC, will i receive OTAs as the source country gets them ? or am i out of band and therefore am on my own?

If you don't change anything, you will get CSCs for wherever the phone was sourced from.

Just got the phone!
It's CSC is XSG/XSG/XSG which looks like "United Arab Emirates unbranded"
First thing im noticing is that it's not restoring my Google backups
Is this because it's a samsung phone and i need to use the Samsung backup feature instead?

It is indeed a UAE phone, good place to be sourced from since XSG gets updates fairly quickly compared to other CSCs.
What issue did you face when restoring the Google backup and how exactly did you try to restore it?
Some people have reported that the Samsung Pay app installed on XSG phones works well in other countries, so you can try that out if you want, otherwise Android Pay should work fine.

Thank you!
Yes, i actually just got a notification for an OTA. I think the December security patches.
Which is aweosme, so i'm not going to flash a different CSC because i dont think i need to at this time!
Regarding the backups; I was expecting to log in to this phone and get all my apps that were installed on my last phone.
But then i realized that htis is a brand new phone and i dont have a backup to restore to!
So i just manually installed the apps i needed and was on my way.
Lastly, yes, i just installed Android Pay and it works perfectly fine.
Thanks for all the help!

If your previous phone is an android phone and you use Google ID on that phone, you should have no problem restoring your apps. The Play Store remembers your Google ID and all of your apps should be restored if you log in with you Google ID.
Im noticing now that of my 2 SIM cards, one is usually around 80% strength, while the other is around 50% strength.
is this possibly an issue with using the wrong CSC for my region?
Or maybe since only one SIM can use LTE at a time, the other SIM is stuck on 2g/3g and it just has crappy reception becuase those towers arnt really in use anymore in my area?

Yeah, that is probably the case.
I had taken my 955FD to UAE earlier this year, used my local UAE SIM in slot 1 for LTE, and my Pakistani SIM card in slot 2 so I could still get texts on that number. Battery life did take a significant hit since the signal strength on one of the SIMs was quite low.
Changing CSCs may or may not have an effect on the signal strength. A good way to check is by using the SIM with poor signal strength in another phone with the same network mode, and see if you get the same results, if so, changing CSC will do nothing. If the difference is very large, then you could consider flashing the CSC although I wouldn't recommend rooting your phone just for a CSC change, especially if you aren't facing difficulties in making calls/sending texts/using data.
I have a 955FD XSG also. Using AT&T. I managed to enable VoLTE by quickly putting the sim on an att branded phone and returning the sim to my phone. I now have the VoLTE toggle and calls are placed over LTE but I can't seem to get the wifi calling toggle to appear.

WiFi calling won't appear without the AT&T CSC.

I'm currently running the firmware from this thread: https://forum.xda-developers.com/verizon-galaxy-s7/development/easyroot-unroot-t3859755. I'd like to try out the latest v4 bootloader 930U firmware but I need to have the Verizon "Advanced Calling" on my phone because of my home in a VZW blackhole. 200 feet in every direction and signal picks up. Anyway, I need to be able to do Wi-Fi Calling. Does anybody know what apk's I need to grab from the 930V firmware? Or is it much more involved than that?
Generally things like that are part of the CSC firmware, as that's what holds carrier apk's and firmware configs. You could try downloading the G930V firmware and flashing just the Home_CSC file, which doesn't data wipe.
However in previous threads I've seen on the topic, people had to use the CSC file to finally get it working, which causes a device wipe.
I'm not quite sure I follow you. I'm currently already on Oreo PDA G930VVRS4CRI1 and CSC G930VVZW4CRI1. I want to switch to Oreo G930UUES4CRH2 or Nougat G930UUEU4BRD1 and somehow get VZW's Advanced Calling.

The wifi calling or "advanced" as you call it, is already enabled on the U firmware.
What Beanvee is trying to explain is when you unzip the firmware files ready for Odin, you can use the Verizon Home_CSC instead of the one which comes with the G930U firmware. This would mean you need to download both firmwares G930U & G930V.

Thanks. The "Advanced Calling" includes the Video Calling and HD Calling along with Wi-Fi Calling. I would like all of those features.

you two are basically speaking two different languages. @cooltt what the previous replies are saying is that your phone already has the apps youre looking for, theyre just not installed because the non-verizon specific versions of the firmware for your phone (which is what youre running) doesnt automatically install it. The CSC is the file inside of the firmwares tar.md5 file that tells it which version youre trying to use. Its kinda like how windows 10 ISOs have every version of windows inside of the ISO, the serial tells it what features to install.
What theyre telling you to try is to take the verizon tar.md5, decompress it in something like winzip, winrar or whatever you prefer, extract the file titled "HOME_CSC", put the phone in download mode and flash just the HOME_CSC file in its spot in Odin. That has the potential of telling the phone to look in the firmware for those features's apks and install them.
Think of flashing a VZW specific CSC as having windows home premium and going in and replacing that serial with a windows pro serial. Very similar concept.
the S7 is the last phone that used the single file in Odin method whereas the S8 and after uses 4. The 4 files are all inside the compressed tar.md5 file and always have been there, but the methodology of deploying the files changed starting with the S8, which coincided with the biggest form factor change in the galaxy lineup in years.
I never did get around to trying this out on my S7. I bought a Verizon S10 on Sunday and am now trying to do the same thing with it. Use unbranded firmware but still have the Advanced Calling. I'm hoping somebody over here might know what to do.
