Changing CSC - Samsung Galaxy S8 Questions and Answers

Hi guys,
Sorry I just need a quick answer to this and I can't seem to find a straight answer anywhere. I have a G935F on 3 UK firmware and I want to change the firmware to either BTU or XEU, as the updates are ridiculously slow on this software version. I have read in multiple places that the CSC code is hard coded and cannot be changed, and then other places say this is merely cosmetic and flashing a new firmware will enable you to get OTA updates from the new desired CSC code.
Please can somebody shed some light on this for me, if I flash BTU or XEU will I be able to get updates as normal, and also which is better to flash XEU or BTU. If anybody can advise would either of these packages allow VoLTE and Wifi Calling to work? 3 supports them on the firmware I am currently on, but I was unsure if unbranded firmwares would support this.
Thanks!

Lollipop in UK (if it ever arrives)

Hi
I installed the German lollipop a few weeks agin and read that UK will be coming soon and it will just require the CSC to ensure that OTA still occurs in future for us in the Uk.
I assume I'll need to do this through Odin, but can someone let me know what the difference is/what CSC does?
thanks

It represents Country/Carrier (specific) code.That are some customization for APN, networks that your country/carrier applied to your phone...

[UK] Unlocked S7 Edge - Enable EE features?

Hi folks,
So as in iPhone user, i've been following the latest Galaxy very closely and decided to take the plunge on Sunday!
Suffice to say, sat in front of me at the moment is my first Samsung (I went for the Edge).
I'm on EE, so i'd like to know how I go about enabling Wi-Fi calling (and VoLTE when it launches - although i'm aware it's testing in several areas at the moment) on my device. I bought it unlocked, direct from Samsung - which probably explains why I can't see the settings for it?
I've ready that I may have to flash the firmware with the EE version to get the features - my concern with that though is tripping Knox, as i'd like to use Samsung Pay when it launches.
Is there a method of enabling the features without flashing the firmware?
Any help on this would be greatly appreciated!

i wouldnt if i were you. i tried that with apple pay in australia and it didnt work. its region locked. wait for the official launch.
for me, my ban offers nfc payments through the phone so i can wait abit for samsung pay to arrive in australia and if im lucky, they will give out free stuff like in america.
i never tried volte calling. but you can always use whats app and stuff.
Its safe to do so,
I bought my S7 Edge from the Samsung store, and flashed the EE firmware, it doesn't trip knox, only custom changes will trip knox, So rooting/custom recoveries and such. its safe to flash the EE firmware. and WI-FI calling working for me, (How to enable WiFI calling). as we speak. But I did do a factory reset(delete everything) after flashing to make sure the CSC for EE was installing correctly.

Ah - just what I wanted to hear
Can you tell me if the EE firmware comes with loads of bloat? Also, will OTA updates work, or will I have to manually flash them when released (I'm sure I read that auto-updates don't work if flashing a different firmware - although I could have misconstrued that).
Thanks

Auto-update will work, but you will have to wait for EE to push the updates out. so might be a delay until they release them, Only difference from buying the phone from EE or Samsung is the firmware, So if you flash the whole phone and factory reset in recovery, its pretty much a EE phone. be warned sometimes WiFi calling will not work until you call up EE and ask them to activate it on your handset, (and that can be a funny conversation, since you didn't buy the phone from them but I managed to talk my way around it on my S6 edge+), And on my S7 Edge it seems to already be enabled after I flashed the EE firmware and enabled in the phone settings.
It's a shame that we still have to install carrier specific firmware to access these things. I thought I heard samsung had overcome this?
Some articles suggested that the S7 could install carrier specific software upon detection of SIM accordingly. This doesn't appear to be the case. I have just had to flash H3G firmware. BTW op it didn't trip KNOX

It is a bit rubbish really - it's one good thing Apple has over android imho. I know Google are trying to go down the same route with Carrier Updates - but they're gonna have to grow a pair if they're going to get anywhere with it.
Anyway, thanks kossiewossie - just finished flashing mine. Hoping I haven't tripped Knox (not checked yet, it's restoring my Google Account backup).
To flash the firmware is it just a case of downloading the EE firmware from sammobile and using Odin to flash it? Because I know for the S6 there was an issue where the partitions were different between the EE version and the unlocked version meaning you had to get hold of a PIT file to flash the EE firmware. Is that still the case?
I'm also considering doing the same. I'm on EE but it came through a re-seller so I've got stock Samsung firmware.
Other than the delay in updates being released, is there any other reason why not to do this? Are you able to flash back the BTU version if you grow tired of waiting for carrier updates and don't end up making the use of wifi calling?

The only benefit I see with the EE firmware is Wifi calling, but as I am in a fantastic reception area, I do not need it. Therefore I see no other reason to use the EE firmware and prefer updates as soon as they are released.
Yes, if you grow tired of waiting for carrier updates, you can flash back to BTE/XEU firmware.
I can't speak for EVR firmware. I used Samfirm to download 4 file H3G firmware and I was not asked for a PIT file.
Interesting there are PIT files included in the files if you unpack them so maybe this was used?
Having downloaded the EE firmware I'm a little confused with Odin.
I have:
AP...
BL...
CP...
CSC_EVR...
Home_CSC_EVR...
Do I need to select all of these within Odin? If so, which CSC as there seems to be two? Sorry if this is a stupid question....

When I did it last night, within Odin I selected files for AP, BL, CP and for CSC - CSC_EVR. I didn't use the Home_CSC_EVR file.
Knowing my luck, i've probably done it wrong - although my phone does seem to be running fine!!
I'm too cautious about flashing the wrong one lol. I'll wait until we know the difference I think!
Edit: Flashed it with the standard CSC. All seems well.
I flashed the standard csc myself and all seems well for over a day now. Would still like to know what the home csc file is for.
Edit. Just found out that home_csc doesn't contain the pit file so it doesn't wipe the phone. So would have to use the standard CSC when changing firmware.

Struggling to go back to stock VOD after installing BTU.

Has anyone managed to successfully go back to a stock VOD firmware and CSC after installing BTU? I've tried installing the VOD firmware from both Samfirmware and Samdownloader but the phone weirdly starts in German with a german CSC and Wi-Fi calling is not available?
IS there something I need to do so it installs with the actual VOD CSC running so I can get Wi-Fi calling and OTA updates?
I have a similar problem after going to dtb unbranded germany from dtm t-mobile germany. Trying to get back to dtm is impossible. As a part of a multi-csc, where dde is the default csc i always get dde, where no volte and no wifi calling is possible. I guess in your case it would be something similar. I too want to get wifi calling working. A shame that it only is available with specific cscs. Apart from rooting it seems there is no possible way, at least for now. I hope someone can prove me wrong.
Didn't want to hijack your thread, but i think its the same problem and maybe someone has a solution.

[Q] How to change CSC Code? (No Root)

Long time lurker, first time poster. I want to express my thanks to everyone who is making this community so great.
I've purchased a S7 edge recently and I noticed I have the TPH (Portugal) CSC code. I'd hope to change it to a Belgian CSC. Two things come to mind:
1 - When I scoured the sammobile site for a suitable Belgian firmware, the only one I found was PRO, which seems to be linked to the Proximus carrier, which is different from my carrier. Is it safe to assume that the PRO firmware is the only Belgian firmware around and therefore not limited to be used with other carriers? Or should I opt for a Luxemburg CSC instead?
2 - I have been looking at the forums for clear instructions on how to perform this, but haven't found this specifically for the S7 (edge). Could someone explain on what I need to do? I'm assuming I just have to download the firmware and use Odin to flash the 4 files, but do i need to set some specific options on Odin before flashing?
Your input is much appreciated.
totally same question. up
This app should let you to change CSC even without root https://play.google.com/store/apps/details?id=com.zigbrick.galaxyregionunlock
The only way to change the CSC on non-rooted devices is flashing the designated CSC file through ODIN. However, there are limits. In case of Belgium I did only find the version for Proximus, too. But the PRO one is a multi-csc file (VFG Germany) and if you flash this you will end up with Vodafone Germany (VD2), a branded rom. Without root that's the only option you have. If you flash LUX then you have LUX which makes me wonder why you even want to change it as TPH is unbranded and you don't gain anything...

Questions about official firmware flashing

Hi all, not had a Samsung phone since the first Note so cant remember a thing about flashing/de-branding on these aside from Odin and I know things might be different now with Knox.
So I've just ordered a Vodafone S8 in the UK and I'm considering switching firmware when it comes to an unbranded one but was hoping someone could point me to a good guide of where to get the firmwares (and which one to use) for the latest updates etc.
Is this still a fairly easy job and doable without unlocking and rooting/tripping knox? Do you lose access to wifi calling on unbranded phones on Vodafone?
Thanks
Go to updato.com and search firmwares for the G950U1 (If those are the snapdragon variant). I always use the XAA as it's not specific to any carrier.
It's still the same method but I'd use the modded Odin which has been posted around here, rename each file and remove .md5 from the end of them. From there it all matches up. BL, AP, Etc. When flashing the csc file, HOME CSC will NOT wipe your device after flash, CSC WILL wipe it. You'll want to wipe initially anyway.
It doesn't trip Knox and you'll lose wifi calling and volte

He's got a g950f which is the European model(exynos)
Thanks for the info, i did a little more research myself and looking at my software version it says SAOMC_SM-G950F_OXM_BTU_0062
My CSC's are listed as BTU/BTU/BTU which as far as im aware means its already the unlocked version correct? There was no vodafone junk preinstalled but wifi calling shows up as working. So im a little lost now, I dont think i need to do anything and I have wifi calling so all seems ok.

Where did you get your S8 from, direct from Vodafone? I've had mine for about 6 weeks now and got mine from Vodafone direct and my CSC is VOD, my current firmware is:
G950FXXU1AQH3
I was just looking into flashing mine with the BTU firmware so I can get the Oreo beta.

I got mine from www.mobilephonesdirect.co.uk they told me it wasn't unlocked so I assumed that meant it came from Vodafone. Not tried any other SIM in it yet to test that side.
Wifi calling definitely works, there's no vodafone crap installed no branding anywhere.
According to
https://www.sammobile.com/firmwares/galaxy-s8/SM-G950F/VOD/
there is G950FXXU1AQI7 for the Vodafone branded CSC im on G950FXXU1AQH3 for BTU.

Ah, I see so yours is definitely unlocked then as I've purchased from them before, same as CPW.
Yes I've checked samfirmware too, I will need to flash the older BTU firmware then by looks of it, however I need to look into it a bit more as I've read somewhere that flashing the S8 is a bit different.
