What happens if I flashed another country firmware??

Suppose in the case I bricked my phone and I don't know the baseband version of it. Now what is the option to recover? Flash stock firmware via Odin but don't know the baseband??? What will happens if I flash another country stock firmware?? Will the phone hard brick?? Or it will work fine?? Thank you

The worst case is that your sim card will not work with that software. This is only if your phone is carrier locked.
If it is unlocked, or neverlocked as others put it, then you can flash any firmware you like, as long as it is for your respective phone model.

Make sure that this phone isn't locked to O2 or any UK carrier.

You should flash Nepal firmware then. It would give you better (more match) CSC code. The CSC (Consumer Software Customization) code contains the info about software packages specific to a particular region, carrier branding and also APN (Access Point Name) settings for data connection.
In my case, my S4 i9500 was made in Vietnam and when I received it, it had a Thailand firmware on it. It is a network unlocked phone. I live in USA. The first lollipop firmware came out was for Russia. So I flahsed the Russian firmware. My CSC showed that it is a russian phone. I used that phone on AT&T network that available in USA, China and Korea, and I had no problem.

Nothing will happen.

@sway8966
Are you really to suggest him to flash Nepali firmware on UK phone? I'll unlock it (the carrier-lock) first and then flash other countries' firmware if need.

Sorry to bump this up but im having problems with my s6 edge (Maybe because of this).
I recently acquired a phone from a relative from UK. The OS is android 7.0 and the carrier is three.co.uk (H3G), we have reset the phone to its factory settings and accidentally didnt noticed that it do auto update on the OS, then this bootloops starts to occur.
The phone isnt network-locked because the phone can receive signals, messages and phone calls on local sim.
Now upon browsing around SamMobile, There is an available Firmware for this mobile and even the firmware which is available to Philippines but only ver. 6.0.1
Is this possible to use the PH one or still i go to UK(h3g)?

help please
once i take the firmware from other countries and then i install to my phone,
does my phone will going to operate that firmware even if it come from another country
because i tried to find firmware according to my respective country unfortunately i missed it.
so please i need your assistance ..please

Has anyone got WiFi Calling to work on a 935FD dual Sim

OK, I flashed my G935FD dual sim with G935FXXU1BPH6_G935FVFG1BPH1_VOD ( I did AP BL CP CSC), it rebooted did a couple of OTA updates, has wifi calling enable, but still wont wifi call, or go into wifi calling mode.
After the flash and OTA's I checked the versions and have :
AP G935FXXS1BPJ1
CP G935FXXU1BPHJ
CSC G935FVFG1BPH1
this is exactly the same as my UK Vod shop purchased G935 single sim, which obviously does go into wifi calling mode
One minor point, my G935FD dual sim phone receives messages dfrom VOD after a sim change stating auto configuration of APN is not possible, is VOD UK still detecting my dual sim device and disabling wifi calling
any ideas anyone pls, has anyone got WiFi Calling to work on 935FD for Vodafone?
cheers
(oh, also tried G935FXXS1BPJ1_G935FDBT1BPH2_DBT.zip and didnt even have the wifi calling check box )

I have mine working on the att version

cool, I have heard from other ATT or UK EE users who have made this work easily, just no vodafone users

update here from me :
Having tried many roms, with no success, I reverted back to a UK VOD ROM, as this was a multi CSC ROM, which defaulted to VOD2 CSC (Germany I think), I rooted the device and changed the CSC to VFG (VOD UK I believe)
Still no wifi calling, though it is enabled in the CSC and onmy account I dont have the check box under phone settings -and have no idea how to force it to appear.
Any ideas pls, has anyone successfully got WiFi Calling to work for Vodafone (UK ??) on a 935FD ?

I am interested in getting a dual sim version of the s7 edge to use with EE in the UK. Could you please elaborate on compatibility with EE's wifi calling? Did you read about it in some forum? Do you know people who have tried it? Do you know exactly which versions are compatible (935FD, 930 , etc)? Thanks!

So you flashed a single-sim firmware (for G935F) onto a dual sim phone (G935FD) and it worked? Did you retain dual sim functionality?

Yes flashing firmware for the G935F retains Dual SIM functionality, mine is flashed with the BTU firmware as UK s7 version

@copex , thanks! Are you on EE? Have you had a chance to verify if wifi calling works?
Also, is there any particular way to flash the firmware with Odin? Or shall I just follow one of the many guides on the web?
I don't need to be rooted, right? I don't want to root because otherwise I won't have access to my work email.

I am on EE but via Plusnet mobile and they do not support wifi calling, i used Odin to flash the device as i changed the CSC to BTU i done a full wipe so i could get OTA updates, i followed the info here.

What do you mean exactly when you say you changed the CSC? When you ran Odin, did you load all 4 files: BL, AP, CP, CSC ? Specifically, did you load the CSC file or the Home_CSC file in the CSC box?
Thanks a lot!

On a different note, where were you able to buy a dual sim s8?... all the ones on Amazon come with a clear "no Warranty" disclaimer.

I am not sure dual sim S8s are out yet - we were talking about the s7 edge. These dual sim phones can typically be bought in countries like the United Arab Emirates or Hong Kong, or on ebay, but if you buy from there and bring the phone to Europe or the US it basically means no warranty. There are also lots of small websites that sell them, but I wouldn't even consider them unless they support the paypal guarantee - who are you going to sue if they don't send you your phone?

when you download the BTU firmware there are two CSC files one will allow the phone to update and keep the data and the other will wipe the phone and you will lose all of your data, when you change the CSC region you have to do a full wipe to get OTA updates, if you upgrade the OTA updates will stop if the CSC region is changed
you have to flash all 4 files.
the csc file i flashed was CSC_BTU_G935FBTU..................................... if i remember correctly the CSC_HOME............... is the one that updates the phone

Want to change carriers an get all the features that carrier provides

I recently got a SM-G950W (galaxy S8 Canada) it was locked to rogers previously now the phone in factory unlocked with a code and I now have a Freedom mobile sim card inside
The phone works fine, but there is some bloatware from Fido that will not go away even after a factory reboot, and I want to ensure that I will be able to get Wi-Fi calling enabled for Freedom mobile.
I would prefer to have an unlocked firmware with no bloatware, but if that would prevent me from getting Wi-Fi calling I would rather just install Freedom mobiles firmware and take the bloat that comes with it.
I'm really a Noob at this and don't fully understand the difference between a AP, CSC or firmware. is firmware the same as CSC?
I just want the least bloated version that will get me the quickest updates and will receive all the features and frequency bands that my new carrier (freedom mobile - previously known as Wind Mobile) provides. How would I go about doing that?
When I run *#1234# I get these values
AP: G950LOU1AQEJ
CP: G950LOU1AQEJ
CSC: 950W0YA1AQEJ
Can someone help me out

There's a thread on this, literally called How To carrier change

Yes I saw that thread. Unfortunately its entirely about switching the US variants. I am looking for advice about switching the Canadian variant from a Canadian network to another Canadian network.

is there a How to on Canadian Carrier Switching?

I've looked all over the forums and all the threads on carrier switching refer to switching US S8 variants to US carriers.
Can someone please explain or point me to a thread that explains how to carrier switch Canadian providers that would be fantastic. In particular I want to go from Rogers to Freedom Mobile (aka wind mobile) . My phone has been factory unlocked.

I can tell you from experience that freedom does not have any carrier specific features, so doing a firmware switch wont benefit you in any way I dont think.
You can however go onto sammobile and download the firmware for freedom and flash it using Odin. Again probably no real benefits. You would benefit if you were going the other way tho, as Rogers, Bell and Telus have carrier specific settings in their firmwares.
But since you are carrier unlocked, you could try a factory reset then put your freedom sim in it and boot up. It might install the freedom files. My S7 worked this way when i went from a Bell locked phone to a Koodo sim...
Edit: That link has an unlocked canadian firmware as well, you could use that firmware too.

Open the dialer and type *#243203855# then select GLW, this will change your csc to wind mobile/freedom, it'll wipe your phone..

Hi Peachpuff. I have an unlocked S8 phone from a Bestbuy canada marketplace seller. I tried using your code to change to the Telus CSC so I can get VOLTE but got the invalid MMI code error message. The about phone says its an SM-G950FD, and the only code the phone appears to accept is the one displaying the EMEI.
Hope you have some guidance on that ?
Thanks

That's not a canadian s8, its an international one, so that code won't work and i doubt you'll get volte working at all.
Just enjoy your root friendly multi sim phone.

Is there a way to change my XAA CSC code to any of the Indian CSC codes?

I've been doing fine since I got the Snapdragon S8 Unlocked from USA but recently I saw many places with Samsung Pay and thought it would be convenient to start using it and when I installed the app it defaults to the USA version, although I can still enter my card I am missing out on a lot of Indian Specific features on the SPay. I am guessing this is because the CSC is set to XAA and not any of the Indian ones. Is there any way to change it to Indian CSC codes without rooting?
EDIT: BTW I have tried going into recovery mode, formatting the device, rebooting it with my local SIM installed which did not work, it's still in XAA code. Please don't tell me it's a Snapdragon/Exynos thing which does not allow it to do it. Model G950U1
