Flashing G930F "BTU" (UK) Nougat firmware in the USA - CSC change needed?

Since there is no official Nougat release in the USA yet, I was planning on installing the "BTU" Nougat official firmware intended for the UK. Do I need to do anything with changing the CSC to use in the USA, or just flash everything as-is in the firmware download? I don't understand if the CSC change is REQUIRED to match the country you are using the phone in, or just recommended. The current Marshmallow build is showing a CSC of OJV (middle east)
What are you USA folks out there doing? I am on Straight Talk (AT&T sim).
My current phone is giving me a lot of problems, and I'd really appreciate a response as I need to get switched over to this S7 ASAP. I realize I can just use Marshmallow but am really hoping to get to Nougat so I don't have to reflash and potentially lose data down the road.
Thank you!
If the CSC you want to change to is not included in the CSC already on your phone, you'll need to use CSC of the new ROM (Not HOME_CSC) along with the other 3 sections, and check the "Repartition" option in PIT settings of ODIN
This will wipe your phone back to factory settings
Are you rooted?

He doesn't need to check repartition. Despite the fact that it is designed for downgrading and unbricking (exclusively, in most cases ), it is not required to do that if only CSC change is needed. Only thing he need to do is using CSC section of the ROM (not Home_CSC because it is preserving old settings in the phone, message to The Founder of the topic ).
Generally, when I was switching to BTU I flashed Firmware with CSC different that BTU (for example Sweden rom) and then flashed BTU sofware. CSC has changed flawlessly
And when you have rooted phone, you can change CSC manually. That extremely ease you effort.
i would just flash the firmware and the csc that comes with it because then you will get updates in the future. if the csc doesn't match the firmware you wont ever get updates so just do a samsung cloud backup and flash the nougat But its weird that someone in the usa doesn'ty have nougat because i thought usa was 1 of the first with nougat.
RiTCHiE007 is right. If you want to receive OTA updates, CSC must match with the type of firmware it comes from. That is why you need to change CSC from US to BTU. Here is a thread that will help you out providing explanation of the topic.

Samsung S8+ CSC change on Exynos F model

Hello,
I have been trying to find an answer to my question or a solution but all the results I found on XDA are Snapdragon model oriented.
My question is about changing the CSC just to be able to receive OTA updates faster ( I don't want Samsung Pay ..) . I aleady know that the product code is hardcoded into the phone I just need to change last three letters of the CSC.
My rom is part of the OXM multi-CSC rom, I flashed it and tried the famous code to change the CSC region but no results so far. I also do not have any other sim card to trick the phone after factory reset.
Could anyone please help ? has anyone been able to change CSC via odin ?
Regards.
Can anyone help please ? is my question a little bit confusing ?

Changing CSCs isn't possible without root or without a local SIM card from the country whose CSC you want to use.
If you're so eager to get faster updates, just flash them with HOME_CSC_OXM as they are released, you won't lose your data and you'll be on the latest OXM builds as well.

No Multi-CSC after flashing Germany's Oreo firmware

Hello, I first bought my phone from Taiwan and the CSC was pointing to BRI(Taiwan) at first but now after flashing Germany's Oreo firmware by following the xda thread, it no longer shows anything in my avaliable CSC, I'm only getting CHO(Chile) and nothing else. Is there a possible fix? I also tried flashing Taiwans firmware for nougat but still ended up with CHO service provider.
Im trying to get back to stock Taiwan firmware because they now have oreo update and supports Samsung Pay while the Germany's firmware doesn't support at all.
Also I accidentally reset my phone with Canada's Sim card in while factory resetting once.
I've attached an image of my phone's CSC info
Any help is appreciated. Thank you
EDIT: another thing I noticed was my phone model changed from SM-G955FD to SM-G955F, is there any way to get it back to FD somehow? In my settings. About phone, it does say SM-G955FD still though
If you change the 'model' of your phone via a flash, you need to flash/change the CSC with the same 'model' of the OS you used.
If it seems a bit convoluted, I'd flash back to full OEM, and make sure that is all OK, and then flash the proper CSC package.

Firmwares for SM-G955F and SM-G955FD are IDENTICAL, your model number has not changed. To change CSC I had to install FW with new CSC, then do factory reset and after first boot I got prompted whether I want to change my CSC (based on inserted SIM card), confirmed, the phone did factory reset again and got new CSC installed. Also, Canada is not included within OXM multi-CSC package as G955F/FD is not sold there (or at least not officially).

Thank you both for your help. I'll try and flash just the CSC firmware then reset when samsung decides to push the OTA again and will see if that solves it. The firmware for Taiwan came out only a few days before they took it out so didn't have a chance to download it.

[SOLVED] Can't receive OTA updates after changing CSC

Hello guys!
I have Note 20 Ultra (SM-N986B/DS). I changed my CSC from BGL (Bulgaria) to THL (Thailand), to activate the native call recording function. The downside of this turns out to be a broken OTA function. I changed my CSC code by using THIS method.
However, it seems I cannot revert it back to the old one. I want to change it again, to receive OTA updates. I don't want to play with Odin on every new update. Any help or advice will be highly appreciated.
Hi, with SM-N986B/DS I changed to INS CSC, original was TMS. INS updates were so delayed...
Try change CSC to SEK (Ukraine), call recorder is included, updates are comming very often.
I did the change with samkey, second change of CSC with samkey and identic phone is free of credit.
Thank you. That's actually solved my issue. Changing the CSC to SEK allowed me to receive OTA. Also, before the change, I removed the sd card and the sim card if that does matter somehow.

Question Flash firmware from other regions & Recieve OTA updates

Dears,
I have S908E 22 Ultra, but my country always get updates very late. So the question is if I flashed other country firmware without changing CSC , will I still get OTA updates ?
Yes you will get but those OTA updates will be from that other region only
Hi, I have S908E 22 Ultra, I want to flash the USA or SM-G9880 firmware (or any snapdragon firmware) is OK ?
Also I changed the CSC code but the last line (country of production not change) example: COO/COO/COO after change CSC: XID/XID/COO. It's possible to change the country of production CSC without root?
Can anyone help with the info if can do it or not, only the last CSC (country of production) other CSC I changed with SamFw FRP Tool but like I said I can change the last 3 letters!
Thank you!
