My G930F came with a VDS Nordic carrier CSC. I'm considering flashing a different CSC to gain some customizations without tripping knox. Specifically: removing carrier bloat, Volte, and call recording. Will changing the CSC give me what I want?

hi mate
Not really , flashing alone the CSC will not de bloat the firmware.
You need a de bloated firmware . check this thread there they show you how to flash a de bloated up to date firmware keep your current CSC and not lose data .....
Changing to a different CSC will enable the option you mention IF the CSC is the same as the carrier that offer those options. If your carrier does not offer those options they will not be available even if you flash a different CSC

My S7 has branded 6.0.1 firmware (PRT), can I flash non-branded (XEO) over without tripping Knox and losing my apps?
Also, are modems carrier-specific, or can I just use stock? (I understand that this is "CSC flashing")

Hi mate
Yes you can , as long as is official firmware there is no risk of tripping knox , most of times there is no problem using the modem from a different firmware ( other country) i am in Panama and i have a UK firmware, working fine
CSC is what it tells the firmware what country or carrier you are using , it will enable a specific set of features design for that country or carrier , like VoLTE , OTA..
If you do not want to lose your apps or configurations you must use the home_csc file not the CSC file AND must be the home_csc from the same CSC that you have in your phone right now , PRT , so first download a firmware from your country, extract the home_csc from that firmware , discard the rest now download the firmware from XEO and flash CP , BL and AP with the home_csc file you had from your country firmware.....tat way you keep all your apps and configurations
Hi all,
I'm back to Samsung after a number of years away at HTC and LG! Last Samsung was an S2 and so I've used Odin, reflashed firmwares, rooted etc. before so know my way around this stuff in a general sense.
I got an S7 from CEX recently to replace my broken LG G3 but the firmware on it seems to be a slightly older / foreign one and I want to get onto a clean UK / EU firmware, so I can keep stem with OTAs that I see friends' S7's receiving. My current firmware is baseband G930FXXU1BPJE, build number G930FXXU1ZPK4.
I've looked on SAMMobile and can see two options for UK unbranded; XEU and BTU. So my first question is what one should I use and what the difference is?
Secondly, when I use Odin to flash whichever one is correct, will I need to repartition? Or will factory resetting after flash be enough to properly correct the CSC?
Finally, will this still show up as an 'untampered' phone, and receive OTA correctly?
Thanks for the help.
XEU has the most updated firmware atm with a February security patch, where BTU is still on January afaik, both unbranded UK firmwares
If you flash them using CSC (Not HOME_CSC) which will reset the phone and change CSC, then you will remain KNOX 0x0 and receive OTAs for whichever CSC you choose, XEU or BTU
No need to repartition
I did read something about needing to flash to another CSC supported by the current CSC on your phone atm (Multi CSC) before flashing to the one you want to change to, but not sure about that, I've only ever switched between BTU and XEU, and BTU is multi CSC containing XEU too

Thanks, I'll stay alert to that possibility. I'll go with the XEU variant and hopefully be ok. Just need to backup my stuff first.

Hello, did you have any luck changing your CSC without Re-Partitioning ?
Im in the same situation right now (DDE CSC, still on 6.0.1) and I am kinda scared after reading so many posts where people bricked their phones.
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.
I'm trying to flash to PCT to see if I get full US feature SPay with their rom.
However, PCT is part of Latin America multi-CSC rom and I'm now stuck with CDR which is the default.
I've read about how to change CSC. So far the only promising way out is to download Combination firmware and change CSC using *#243203855# in Factory IME to change CSC and then flash back to stock firmware. But there's not a lot discussion I can find... So will this operation work? Will it trip Knox? Can somebody with experience let me know...
Hey,
I have a G955F, but the carrier i got it from still hasnt released Oreo, all the others in the country did.
I was wondering if i do flash the orig samsung firmware, if my CSC will change and if it does what are the downsides to it?
My firmware CSC is MET and the CSC country is Ireland/IE .
And if i install a sim free FW like the orig samsung one, or the one from Vodafone Ireland and afterwards i install the MET one when they release Oreo, would the CSC change back and have warranty intact?
Thank you.

Yes, you can try flash the firmware from another operator of ireland like three or vodafone. If you use any carrier specific things like VoIP or VoLTE, these will not work with another csc, as long as you just want sms/call/internet and don't care that there are some apps from three/vodafone installed, you can download a firmware from here
Your CSC then will change to either 3IE or VDI which, stated above, should not make any problem.
And yes if you flash MET when it's released you go back to your og CSC.
In terms of warranty it is always intact. Changig the CSC does not trigger knox 0x1. (The indicator for samsung if warranty is void or not) But you can ignore that, as in EU countrys this doesn't matter (read here under "Legality")
