As this as phone has got ee branded phone. If I installed a custom firmware btu version black edition . What the chances of unlocking it via the method above or would this phone still know in it a ee phone what are your thoughts regards James. I don't want to root the phone. I'm quite happy to put a btu black edition on the phone . I have used odin in the past on my old i9505 but that phone was already unlocked
Changing firmware will not unlock the phone. To get the proper menu to appear you have to downgrade the modem (or firmware) to Android 4.2.2, then use the service menu. If the service menu does not work, your only other alternative is to root while the modem is downgraded and run RegionLock Away.

Many thanks for your reply. So if I down grade my firmware to 4.2.2 btu so I can enter the service menu . Are you saying this mite work 50/50
I did the downgrade myself when I lost my SIM unlock. The service menu worked but I messed up somewhere and failed to unlock. RegionLock Away worked perfectly.

Dont know if this will help you but after *#0011# press back then key input and type Q0 instead of 1. wait a few seconds and should take you to the menu.
So i bought a 2nd hand s7 edge off kijiji. No issues with it, but i've been reading that wifi calling is an option with my provider (Bell Canada, hence the BWC csc) and I'm wondering what benefits there are (if any) by changing the CSC in my phone, or if making this change would then enable the option.
I can enter the *#272*IMEI# and get the option to change it, i just want to make sure i'm not gonna mess anything up by doing this.
Any insight would be helpful. Even if there aren't any benefits for doing this change, i'm still curious as to what kinds of things this change can do, whether they be good or bad.
Thanks in advance!
Bump for visibility
I believe all the firmware from any carrier is fine, as long as its from a Canadian Provider.. I bought my Edge from Samsung store... Went onto the Sammobile and flashed a general canadian firmware with the sept update, no issues...
Only way to change the CSC is to root your phone first and then install SAMSUNG INFO software from Google play Use the Csc Changer option and then select your preferred CSC from the list and install then your phone will restart and will restore Factory setting *before doing that make backup your phone* and then your phone will restart with new CSC ......You are done ....
NOTE: this process is only be possible with multi CSC phone or international models
I am on Three (UK) and I now understand that wifi calling is a carrier feature and a phone purchased direct from samsung will not have this enabled.
I have found that you can flash carrier firmware to enable this but I have a few questions:
Can i do so without the carrier bloat such as a horrible boot screen and preinstalled apps?
Will this affect my Knox / android pay / secure folder access?
Is there any way I can flash the wifi calling functionality without a complete reflash?
Thanks
Does 3 have WiFi calling? I don't think so.
Unless it's new. I left them in Feb after many years to get Volte. There was no voWifi then.
The reason I ask is voWifi worked out the box on my unlocked BTU S8 with EE.
Volte did not and required me to flash the EE firmware. This works a treat. No knox trip, no branding or bloat, no AP or secure folder issues.
If you want supervoice, you will need to flash the firmware.
Edit - seems I was speaking bollocks, yes they have WiFi calling, called "embedded wifi" now. As said, with EE this worked out the box for me. Only needed their firmware for Volte.
Three does have voWiFi aswell as voLTE/vo4G (In select areas).
Call Three and make sure WiFi Calling is enabled on your account and then you should receive a carrier update adding the WiFi Calling option.
(Source: Method I used with Vodafone UK)
I though three used an app for WiFi calling? Or at least that was the only way I could get it to work when I was with them a few years ago.
Edit: I've just read that they have built in vowifi but only on certain handsets. Perhaps the s8 isn't supported as yet?
I did a chat with them, S8 is supported for voWifi it seems.
Here in Poland, phone with non branded system works with WiFi calling. There's setting in dialer options (three dots menu). After I toggled it on wifi calling started to work.
TIM purchased s8 here, flashed the h3g firmware and volte and WiFi calling both function.
Bloat is there (boot screen and m$ office).
No call to three required to activate, it just works as soon as the correct CSC is on the device

Three's website does confirm the S8 is compatible for WiFi Calling.
Go into the Phone app, press the three dot's -> Settings and see if there is a WiFi Calling toggle, this is at the bottom of the list.
If WiFi Calling is not there, make sure you have the latest update installed.
Update via the following guide from Three themselves: (please add a :// after http and make sure there are no gaps as I am not yet allowed to post links): http support.three.co.uk/SRVS/CGI-BIN/WEBISAPI.dll/,/?New,Kb=Mobile,Ts=Mobile,T=Device,varset_pid=40031,varset_cid=40041,Case=EXT(EM114337)
I've literally just switched from BTU to H3G and WiFi calling appeared instantly during setup. I did have to use CSC rather than HOME_CSC, as the latter caused Odin to fail first time around. I have also confirmed WiFi calling and texts are working, which is a huge plus as the lab in which I work seems to block all mobile signal!
Did installing H3G also enable VoLTE?
Cheers
Thanks for the quick replies everyone! Wifi calling is enabled in my account (it worked on my iphone) but the wifi calling option is not there at all. (I've checked all guides, including the 3 dots then going into phone settings) I know there is an app but it is horrifc, calls often don't come through at all, the app requires a persistent notification and is a major battery drain. @goRt @foo25 - > did you guys follow a guide for flashing three firmware? Do you know of any way to avoid the carrier bloat / sim lock?
Thanks all!
I've just flashed the three firmware from the Samsung version. After flashing, inbuilt Wi-Fi calling just worked. Wi-Fi calling toggle also appeared in phone- 3dots- settings menu. 800mz band 20 LTE also started working after switching firmware which means an extra bar or two when band 3 LTE signal is low.
The only downside I could see is the three UK splash screen on boot. I haven't noticed any extra bloat apart from the three likes app which I uninstalled straight away.
The phone is not SIM locked by flashing the carrier firmware.

I didn't follow a guide but there are plenty around for flashing stock firmware on the S8 or S8+.
I just downloaded the latest version of Odin, and then the latest three.uk firmware from Samobile. I unzipped the firmware then loaded each of the components into the relevant Odin section ie. CP into CP section AP into AP section etc. I made the mistake of loading the 'CP Home' firmware into the CP section of Odin which caused the flash to fail which required use of Samsung emergency recovery procedure. I did that three times before trying loading 'CP' part of firmware into CP part of Odin which worked fine.

*Download latest odin
*download desired firmware. (samobile) and extract it.
*go to settings>about device>software info>tap build number 7 times until developer options enabled.
*go to developer options and enable USB debugging and OEM unlock.
*plug phone into pc and let it install the drivers.
*turn off phone and boot to download mode.
*open odin and click AP. Insert the firmware you just downloaded.
*odin options should be: auto reboot checked, F reset time checked, repartition UNCHECKED.
*connect phone to odin and it will say added. COM box will turn blue. Just click start and let it do it's thing.
The first boot up can take a short while.
Thanks to everyone for the detailed replies.
One more question: I use secure folder and plan to use android pay. My colleague told me that flashing a new firmware will trip knox which will render these features unusable.
Will flashing the official 3 firmware do this? I'm only flashing to get a feature as advertised (there's a lot to be said for iPhone's just "working" )
Thanks

Aslong as you flash official samsung firmware then knox will not be triped as its signed by samsung. Knox only trips when flashing twrp, root or any custom roms.
Before you start, do you have the option for wifi calling in phone>settings right at the bottom?
Like this
Hi all i have flashed my btu s8 to h3g and i also have the wifi option in the menu and it works great, however i can't find the volte option anywhere and i have never yet seen the symbols for it on my status bar.
When i had my old btu s4 i also flashed that to h3g and i remember the volte symbols showed up in the status bar.
So do i need to do anthing to activate volte?

Hi there,
There is no option for volte, if your network supports it then it will automatically be on where ever you have 4G signal. There is no option in settings but the icon looks like in the screenshot
Currently on Snapdragon latest official Oreo with XAS (unbranded Sprint)
My phone was an originally Verizon branded, it now has XAS U1 firmware (model shows as U1 in settings)
I want to flash either U1 or U of ROM with csc of SPR. The reason I want to do this is because I want to fix/enable Calling Plus/Wi-fi settings.
I really do not care if my csc says XPR or SPR afterwards, I'm just thinking that flashing a rom designated as SPR might fix my Calling Plus/Wi-fi issues.
Is it possible when using Odin to flash, to use Home CSC and not wipe data.? I still feel with unrooted phone backup and restore still requires a lot of manual setup and I hate constantly doing this every time I flash.
Note: I've already tried to get wifi calling working using both Nova activities and in the phone settings without success , have been following the other thread about enabling Calling Plus on unbranded rom
After throwing in a T-Mobile sim and then going back to Sprint sim, I was converted to SPR csc. Sprint always seems to do this. So now I don't need to change CSC b ut I still am struggling to get wifi calling
The firmware for SPR and XAS appear to be identical so I am wondering if I should try to flash the U version of the rom . And of course attempting to keep data
FIXED?? - Getting back to AT&T stock from S8 Factory Binary (failed carrier change)
==== Latest update (I am not an expert but please check out (at your own risk) ============================
All - I installed latest Tmobile firmware for SM-G950U downloaded from sammobile (G950USQU5CRK1) using odin3v3.13.1.
To my pleasant surprise I find that Wifi Calling etc works fine. You need to have TMobile SIM in the phone when you flash the firmware. I believe S8 automatically customizes firmware based on sim detected (I tried AT&T/TMO sims and it did).
It is likely that all the carrier change guides are no longer relevant (at least as of V5 bootloader) I am not an expert but please check out (at your own risk)
========== OLD Thread =======================
Will appreciate help.
Here is what I did or wanted to do: I switched carriers from AT&T to TMobile and tried to install TMobile stock using these instructions
https://forum.xda-developers.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817
I have a V5 bootloader so I used Factory Binary from here https://forum.xda-developers.com/ga...bination-files-bit-5-g950uu1-g955uu1-t3816112
Current State: I am on factory binary, but the instructions to change carrier files (32-33 in carrier switching) don't seem to work for V5.
I would like to get back to AT&T stock - but cannot figure out how to. I cannot find AT&T stock firmware with V5 bootloader anywhere. ANy help / guidance is appreciated

I have come to believe this as well. I was flashing the unlocked firmware on mine and if I kept my Xfinity wim in it it no matter what,would default back to my cct csc. So I tested and inserted other Sims flashed a CSC and auto configuration took over on boot and would reflash itself with the apropriate carrier CSC and sales codes...The auto configuration seems to handle most carrier changes. There is also a hidden menu where you can select a csc. And again. If I selected one if I had my sim in it would disregard and keep sims csc. If I removed it would take til I inserted my carriers sim.
Also at the bottom of this hidden menu you can select to disable auto configuration....
Don't know if this helps your hunting's and findings but it was observations I made
