Switching Firmware on Galaxy S8+ - Samsung Galaxy S8+ Questions & Answers

Today I tried switching my s8+ which is an Italian unlocked model (ITV) to a United Kingdom unlocked firmware (BTU). I followed all the steps as this is not my first time flashing firmwares with Odin. I found a thread online saying that since BTU is a multi CSC , I need to flash a ROM that's is outside the multi CSC , so I decided to flash a O2 ROM , straight after flashing the BTU hoping that it would change the CSC , but it didn't instead it stood on ITV, the country/region is still on Italy too. Can anyone explain what I done wrong pls ?

Why do you even care about csc ? Install rom for your coutry "global", not branded soft and that's all...

BTU is not branded, it's unlocked with no carrier. Updates are also provided directly from Samsung. I would like to change the ROM for faster updates and features

So according to what I read it's impossible to change the CSC to BTU on the Galaxy s8 unless you have a UK Sim. This used to be possible on the s7.

But NOT possible anymore on the S8/S8+
ITV & BTU are both part in OXM. When you flash BTU-ROM, your device will stay ITV because both are in OXM...

Yes, S7 didn't use the multi-CSC, each region had it's own CSC.
But the Euro S8 has Multi-CSC, so it won't change region until you put in a SIM from that new region.

Thanks guys for helping. I just wanted to change the CSC for quicker updates and for region specific features like Bixby Voice when it gets released in the UK.

[Q] Change CSC Without Root

Hey guys!
I have an unlocked Note Edge (N915G) that I think was originally from StarHub because the CSC is currently STH. I want to change to XSP which from what I've read is the unbranded stock ROM for that region.
My issue is that after trying multiple times with procedures from multiple threads here in XDA and on some other forums, I can't seem to change my CSC.
I have the lastest XSP firmware from SamMobile and the latest Odin.
Does anyone have a sure way of changing CSC without root?
I'd really appreciate the help...
Thanks!
A little help please...

Both STH and XSP exist in the multi-CSC firmware OLB.
I doubt you can't change the CSC without rooting.
Damn! That's what I was afraid of...
Is there any way to make the firmware single CSC?

Does anyone have a mega link? I'm cheap and only have free access to sammobile :fingers-crossed:
Which odin are people using to flash firmwares.
Warning
OFFICIAL STOCK Firmware-update (Odin) thread Samsung GALAXY S8+ SM-G955F
Be advised, that BTU is now part of the Multi-CSC OXM
OXM has a lot of CSC's included! If you want to change i.e. fm Vodafone-firmware to BTU, the possibility is very high you won't get the BTU CSC but the 1st CSC in the package of OXM, which is AFR
I use Odin 3.12.3

So flashed stock firmware with the XEU and BTU CSC on my Vodafone model and it gave me the XEU CSC so I'm happy with that
Will flashing xeu unlock the phone? I need to finish my ee contact before using Vodafone!

Did you download the BTU from sammobile and flash as per the secure pin instructions? Is it luck that you got XEU from the flash or likely to do the same on my Vodafone model also? Thanks.

I didn't follow the secure pin instructions. I used the program SamFirm and downloaded the BTU rom which had the Multi-CSC, my firmware was Vodafone branded and had the Vodafone VOD CSC.
Once I used the correct Odin and flashed the BTU rom I reset the phone in the settings and then I had the XEU CSC which is the correct CSC for Ireland and the UK.

Use Odin 3.12.3 and CSC_OXM (NOT HOME_CSC_OXM)
Your device will be resetted afterwards...

Thank you. I flashed and now have build number NRD90M.G955FXXU1AQDD
Service provider software XEU/XEU/VOD
Is this UK/IRL XEU or still Vodafone UK firmware?
Excuse my ignorance, what is BTU? I am with O2, what benefit do we get from flashing BTU, no bloat apps?
Also I haven't yet accepted any updates, if we do, and realize for example we want to Re-map the Bixby button can we backtrack with this Firmware?
So doing this did not trip Knox ?

Stock firmwares will never trip KNOX.

Wich one is the internation "Generic" firmware for G955F

Hi, i have a s7 edge and the "generic" internation version of the exynos variant was the BTU from Uk, the one that i think got the oficial updates faster.
In the case of the G955F im not sure about that cause i think BTU did not even have the pink screen solution firmware but Netherlands got it before, is PHN the new "generic" faster csc to get the updates for the exynos version like it was with BTU for s7 edge?
Im trying to get the g955f firmware that get the oficial updates faster.
Tnx.

Don't think BTU will be around anymore. I believe XEU is the CSC for UK and Ireland.
PHN is probably a region specific CSC.
Samsung has grouped quite a few CSCs and made a multi-CSC code called OXM, so you can flash whatever (as long as it isn't carrier branded), insert a local SIM card from your country and go through the setup menu as you would normally when you flash a new ROM.

About CSC G955F

Hi, anybody know if theres any csc/multi csc that is unbranded and not part of the OXM big multi CSC?
Ive downloaded several firmwares from sammobile to try to find a unbranded firmware not "european" for the g955f and not inside the OXM, i would like to try a latinamerican unbranded firmware but it seems they r all inside the european OXM and the ones r not have all the carrier crap (splash screens and uninstalable bloatware).
Why do you want one that isn't in OXM?
I want a non OXM cause several things like bixby news and samsung members stuff sometimes appears in german and i can barely speak english lol, thats why i was looking for a latinamerica unbranded firmware but all unbrands like ARO or ZTO r inside this european multi csc so i always get OXM as default csc and i want a default english/spanish unbranded csc.
SOLVED: if anyone interested i used BVO (Bolivia) CSC and now evething is ok.

Changing CSC only with Odin?
Hello If I want to change my CSC (MID) to another one let's say the UAE one, can I simply flash Home CSC in Odin? If yes should I follow the same step as flashing an entire FW ? And can I find the Home CSC alone or I have to download the full FW Zip?
