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

Can I flash XAC firmware on my Rogers SM-G950W?

So it's basically the title. I bought a Rogers(RWC) model of Galaxy S8 G950W and I wanna re-flash the firmware to an unbranded one like the XAC one. The thing is I saw that the Rogers baseband is not unlocked and the XAC is an unlocked one. Can I flash the unlocked firmware on a unlocked one? RWC to XAC
Cheers!

Yes you can, but don't assume that you will unlock your phone after you flash that firmware. If you want to unlock your phone, contact other site that will offer for factory unlocking on that phone or use any gadgets tool that support on that phone.
Note: becareful of modifying the baseband of your phone mostly to those enable bootloader and Knox, cause you may brick your phone or unknown baseband.

The only reason I want XAC is because it's unbranded and without bloatware apps. I think my phone is already carrier unlocked because when I bought it I specified that I will use it in another country. I've been using it with no issues in Romania for half a year now. What do you mean with baseband modifying? I will just flash the exact same firmware as the one I have now but from XAC not RWC. It's my first time doing this. I've did a lot of research but I'm still a bit worried about doing it.

No need to flash anything you can simply change the csc to xac and it'll wipe the phone.

so was their any problem?
i see both rogers and xac on sammobile
which is better?

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

Other firmwares will work you might just be missing features like WiFi calling. I don't know the exact dialer code but they is a preconfig dialer code to select csc so once you got the latest you could try that. All the firnwares are identical for each us model you wont brick from flashing another carriers

So thats yes right? I can use other carrier rom without any problem?

please some one answer... my device is att s8 smg950u. so can i use smg950u1 firmware to flash 950u?

As long as it's unlocked. A g950 u. U1 and w all can use any csc from carrier firmware. Pop your sim in and flash your carriers csc from firmware

My phone is G950U but it's made in China and works fine with Bulgarian SIM. I have no info about the original carrier. CSC code is TGY, can I flash G950U1 with CSC XAA (Unlocked)?

Yes, the thing is I don't have my carrier CSC available for download since I'm using it in Europe. Wondering if I need to revert flash how to source TGY (Hong Kong) factory rom? Seems all available for download are US-based CSCs only.
My main concern is OTA is currently failing completely, I am hoping to restore by moving away from the TGY code, does that need carrier switching process or just flash 950U1 on top including user data ?

Im pretty sure u1 model pretty much is csc-less i would try to flash the u1 firmware directly and flash the home csc in u1 firmware which should leave it open. BL" "AP" "CP" "CSC" is all you should flash. User data would add a carrier. If you dont it will leave it open.....
If updates are all your lookong for. Just use odin to manually update

I tried 950U XAS and 950U1 downloaded with SamFirm and all versions of Odin but all failed . Strange my S7 from Verizon is able to use OTA in Bulgaria but not this Hong Kong S8.

You are either using the wrong odin or a older firmware.
Or. To flash unlocked firmware you must first flash the combination file then unlocked firmware.

unlocked G950U CSC/update confusion

Sorry for a noob question. I haven't been here since my days with an S3.
I pick up an supposedly unlocked G950U on ebay a week or so ago. When I got it It had G950USQU3CRE9 from 6/18 firmware installed. I put in my Mint Mobile SIM and it worked and had no carrier bloatware, but would fail when doing a manual update. Strangely in settings the Service provider SW ver. section was absent. I downloaded at installed via Odin G950USQU5CRL2. Magically the Service provider SW ver is now in settings.
Trying a manual update it downloaded and installed G950USQU5CSA4. SWEET. But I'm confused why I recieved that update.
Under Service provider SW ver it now lists;
SAOMC_SM-950U_OYN_XAS_OO_0075
xxxxxxxxxxxxxxxxxxx
XAS/XAA/VZW
Who am I getting the update for? Sammobile doesn't list SA4 for CSC's XAS (unknown) or XAA (unlocked) but does for VZW
The Phone ID app lists my product code as SM-G950UZVAXAA
Am i getting the update for verizon but a XAA unbloated one? or what? I would think XAS would be my active CSC.
Confused .... My last time playing with phones CSC didn't exist and I can't figure it out.
Also, I would love to flash the G950U1 firmware but there isn't a version a current as SA4, even the pie betas, and concerned about a brick.
Any help in understanding would be GREATLY appreciated.

Xaa is unlocked firmware. I think xas is sprint. But the third vzw means your sales code is verizon so you should be getting updates from them. You can use sammobile or updato get the latest and flash home csc with your sim in and it should go to your carrier. 5th digit from end is bootloader revision thats what you have to pay attn to. As long as you get revision 5 firmware ypur gold. We have locked bootloaders so you cant really brick with odin. You have to flash a rev 5 combination file then the u1 firmware which is the unlocked firms
So what i think is you got a sprint phone with unlocked firmware but with verizon as a sales code for end user if im not mistaken... If thats the case it is most def unlocked sim wise.

I have a couple of noob questions as well Since I'm new to CSC era...
Got s8 950U and was not able to update FW for several months now due to no functioning OTA and Odin failed as I lack the combination file knowledge. My phone appears to be for Hong Kong market with Snapdragon and I use it in Europe.
1) Is it possible to unlock OTA by switching CSC to local provider? Not sure if 950U is even supported in Europe CSCs? What if I pick XAA instead of local one?
2) Any idea how to update to Pie and unlock OTA/Samsung Pay/Secure folder etc.? What is the correct formula to understand which combination file to use before flashing latest Pie 950U1 XAA ROM G950U1UEU5DSC1?

Nobody able to help at least slightly?

i have the same problem with my s8 , thar has csc of hong kong tgy and won't me let download the last updates also i can't open samsung health secure folder s pay ect....any solution ??! ,, thanks in advance

I have the same issue. Phone name is SM-G950U but CSC is TGY (Hongkong). It can not be updated via OTA and I don't know what is its correct CSC.
