[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.

[UK EE] Flashing over Samsung firmware

Hi All,
I've got terrible signal where I'm living at the moment so I'd really benefit from getting the wireless calling through the EE firmware.
I've downloaded the firmware file but I'm a bit stuck. The firmware file itself has extracted to five separate files:
AP...
BL..
CP...
CSC...
HOME_CSC...
I'm assuming that I've got to select all of these within Odin, however I'm unsure of the difference between the two CSC files. Both seem very similar in file size.
Does anybody know the difference and which one would be the correct one to flash?
Cheers

What was the format of the file you extracted those from?

How do you tell what is on the phone mine said it was coming from ee but then it said it was coming from the company I used which was buymobiles.net so I don't know if I have a proper ee one or a sim free I guess so might flash software once you work it out

You've probably got an unbranded one like me. It's usually pretty obvious when booting up whether it's carrier branded or not.
Think I'll wait for now until somebody can confirm the difference. I'd like to know what it is that I'm flashing

Yeah I think I am unbranded I do have the wireless option and it is on my package I called to check might turn it on it says it can take 24 hours to turn it on.

I've got no option for wifi calling in my settings. Boo! ;-(

Mine is settings, applications, phone then wifi calling at the bottom why would I have it and you don't my phone is not from ee weird

I have the option and my handset came from EE but appears to be unbranded.

Perhaps the branding isn't as obvious on the s7 then. I definitely don't have the option in there
My CSC is XEU with the firmware on my phone

OK so for anyone thinking of doing the same, I have gone ahead and flashed the firmware and enabled WiFi Calling.
I selected all files in Odin with the exception of "HOME_CSC" (I used the standard CSC_EVR).
After enabling the option in Settings -> Applications -> Phone, I text WiFi Calling to 150.
As I'm in an area with crap signal I can already see the WiFi calling symbol in the nav bar and have made a few calls with it. All seems well.
Some very subtle changes in the EE firmware but very close to the stock in terms of branding.

@mmotti The EVR firmware on Sam Mobile is shown as G935FXXU1APB9 is that the one you flashed that enabled wifi calling on EE? Thanks.

Flash the CSC file that contains a PIT file in it, The firmware on Sammobile has a CSC file called "CSC_EVR_G935FEVR1APB4_CL7211170_QB8683672_REV00_user_low_ship.tar" and that's the one you need to flash, otherwise Odin just get stuck if you flash the "HOME_CSC_EVR_G935FEVR1APB4_CL7211170_QB8683672_REV00_user_low_ship.tar"
I bought my phone from the Samsung store, and flashed the EE firmware, it will wipe the device(or did for me anyway). but now I have WIFI calling and working perfectly, only issue with using the EE firmware is that firmware/security updates are super slow :crying:

I did it and everything is fine. I got WIFI calling that is working and that was my main priority. Doesn't seem to be any downsides compared to the XEU firmware.

Hey everyone.
Thanks guys this is just what I was looking for, im using an EE sim on pay as you go but I have an unlocked Galaxy S7 Edge that I bought online NOT from EE.
1. So If I install this firmware I should be able to use wifi calling and hd voice?
2. Are there any downsides to flashing this firmware?
3. Will this reset any settings in my phone do I loose any information.
Thanks
Thanks for your help

How to unbrand S8?

Hey people,
I have recently bought a G950F in a pre-sale from Vivo, which is the carrier I use here in Brazil.
I hate those carrier extras (apps, splash screen and stuff). Every time I buy a carrier branded phone I flash it to get rid of that stuff. That's what I wanna do with my new S8.
I went to Sammobile site and could not find a specific ZTO ROM. So I took notice about multi-CSC ROMs. I was then searching for a multi-CSC ROM which fits my phone, and I found this one: https://samsung-firmware.org/download/Galaxy S8/60y7/UFU/G950FXXU1AQCC/G950FOWT1AQCC/
This is for Uruguay (UFU), but also is exactly the same ROM I have in my S8, and included ZTO. Since it's for a different country/region, I flashed it (using CSC file, not home_CSC), hoping I was debranding. But I was not, my S8 is still branded.
How do I unbrand it? I have read that I must flash a OXM CSC ROM (it also includes ZTO) to change the original CSC of my phone, since it may not have changed because it was the same that it already had. Is that right?
I will try now an Argentina ROM (https://samsung-firmware.org/download/Galaxy S8/98v5/ARO/G950FXXU1AQDG/G950FOXM1AQDG/) which is OXM CSC.

Samsung was pretty strict about what carriers were allowed to install this time, at least in the US. Try to see if you can just uninstall the carrier specific apps, on my phone nothing was in the system partition so they could all just be removed.

Not here in Brazil. I can uninstall some, but not all carrier apps.
What bothers me is the awful splash screen. I can't remove that.

When I had a Galaxy S5 with a 3uk or ee splash screen if I remember correctly there was a oem folder or something similar which got loaded everytime irrespective of what rom you flashed, maybe that's the case with branded s8's?

I don't think so. I had my S7 flashed to debrand it, and that did not happen.
Yesterday I flashed my S8 with that argentinian ROM I have mentioned (https://samsung-firmware.org/downloa...G950FOXM1AQDG/). It looks ok now, without carrier splash screen and bloatware.
But sometimes I get a notification from AutoPreconfig, asking me to use new apps and configurations from my new service provider. If I open the notification, it says that to use apps and configurations from my new provider, I need to restore my phone, all my user data shall be lost, etc. I can press "ok" and nothing happens.
Why does that happen?

What i did was this:
1. get you phones imei:
go to dialer > dial *#06#
take a note of your imei without the /01 at the end.
2. go to phone dialer > dial *#272*(your phones imei)#
3. choose which csc you need and install it.
your phone will reinstall firmware with the new csc region you choose.
done.
Just done this to my S8 SM-G950F and switched from GLB(carrier) to XTC(unbranded) csc.
hope this helps.

Flashing BTU CSC results in XEU

Hi all,
I have today received my S8 from EE and flashed the latest stock BTU firmware with Odin.
My phone is reporting that I have an XEU CSC. Is there any way without root to get the BTU CSC to register correctly?
Cheers
Edit: It also says that it's manually applying EVR if I boot into recovery. Odd..

XEU and BTU are the same. Also, all unlocked variants of the S8/S8+ in Europe share a common "merged" CSC, OXM, which will activate the proper CSC based on the first SIM card inserted (hence why it's important to insert a SIM before first boot). XEU is the new BTU, so just live with it.
The device also has its stock CSC code burned into it, so even though you can flash another CSC, it will always know what the original CSC was.

Latest BTU SM-G950F firmware from http://fw.updato.com
Updates should be fine and also released a lot sooner as there's no waiting for EE to release them. Wi-Fi calling is fine too.

Changing CSC

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!

Hi if this is of any help i was on Vodafone and decided i didn't want there bloatware on here so i flashed the latest XEU as it was newer than BTU.
When i go into the phone app it shows me what my old csc was and the active one which is xeu you do get updates plus i got WiFi calling enabled still but had to get vodafone to activate it on my account again.
