Flashing from VZW to XAC ? - Samsung Galaxy S8 Questions and Answers

Hi, I'm really confused, can I permanently remove Verizon (SM-G950U, CRB9 (Oreo)) from my phone by flashing the Canadian firmware ?
If it's possible, how can I do that ? And I've an activated SIM card in my phone, does phone/message/LTE will still work after (I'm using a GSM provider called «Bell» (I'm Canadian)) ?
Thank

Flashing your phone with the Canadian firmware will remove the Verizon bloatware, but will not carrier unlock the phone. That is to say the unlocked firmware is not an unlocked phone.
I find this post incredibly helpful:

I used this app and show me Austria!
But the carrier no!
"Mobile Operator Name" is the carrier.

Check your phone's active CSC, they usually have the same lock status for every phone.
Easiest method is to use another carrier sim card and test it on your unit.

No, updating the software doesn't change the carrier lock status. If it was previously locked and was unlocked, it will stay unlocked. If you will update through flashing, just be sure that you are flashing the correct software intended for your unit to avoid problems. If you flash your phone with a different firmware with locked csc, your phone will be locked.
Thx Jopat...
In the past i have a Samsung Galaxy s3 and after one update the phone relocked himself...

This appears to be an unlocked International version for the EU. But the Forum Moderators checking into the update issue.
You can check http://samfirmware.com/ to find what country your CSC code was built for. This is the CSC for Austria (A1) : G900FVFG1ANE1
This senior member says the towelroot works for the G900F

That's what you have to know yourself. If the network you are using has a history of locking the sim, then it's almost 100% sure that your S5 is locked. S5 was well-prepared for its distribution so the CSC of the network is surely fully configured. Look around here on XDA and take note of the firmwares they are using for modding their custom roms, that'll give you a good idea which firmware is easy to configure. You can start reading with gridflash's suggestion.
No...the s3 initialy was locked on VODAFONE UK!i UNLOCKED AND THEN,WHEN I MADE FIRST UPDATE THE PHONE RELOCKED HIMSELF.
THE S5 I BUY FROM A GUY...AND HE TELL ME THAT THE PHONE IS NEVERLOCK.
I LOOCK FOR THE CSC AND FOR THE AUSTRIA IS THE SAME FOR TELERING AND T MOBILE...
AND THE SAME CSC IS FOR AN UNKNOWN COUNTRY...

CSC IS TTR
WHAT COUNTRY IS TTR?
^Someone told me it works for others too. Anyway, just ignore it, there's a fee for the query when I tried it just now.
Anyway, why not just borrow or buy another carrier's sim card and try it on?
I use it with a romanian sim card VODAFONE RO!
i DON'T KNOW THE ORIGINAL CARRIER...THAT'S ALL!

I'm getting very confused which info you really want to know. If you want to know the original and/or current carrier, Phone Info will give you that info as previously stated. Every other details, Phone Info will provide, only exception is the network/carrier lock status.

Possible to change carrier firmware from Rogers to Bell?

Hi,
I bought an Rogers S7 Edge, but for work reason, I need to flash an Bell firmware in it. I am not root and won't root it.
This will trip the Knox. So I'm okay with it.
Would it work to flash another carrier firmware to my Rogers phone?
Thanks!
Do I also need to put all the file? Like BL, CSC, etc.
I know AS of course.
Thanks!

Yes it works and you won't trip Knox. Use Odin and the rogers official firmware. But why would you switch anyways they're identical. No?
Does the secure PIN need to be ON also ?
Some how to have it on.
Thanks

They are identical software, literally. It's multiCSC. All Canadian carriers get identical software, it just reads the CSC off the SIM card you have installed and adds the appropriate bloatware/features/APN for your carrier on boot (after flashing).
There is literally NO difference between the Rogers/Bell/Telus/Videotron/etc software.

Flashing international Firmware

Hello everyone,
yesterday, a family member gifted me an s7 from the USA (SM-G930P). He bought the phone off SPRINT as a SPRINT unlocked version, and, of course, because I live in Europe and want to use the phone with a European SIM card I have the "hands free activation" mark that is sitting on the top left edge of the display. I also noticed some changes, for example the "mobile data" toggle is nowhere to be found and also I don't have the options to choose the network mode (2G/3G/4G). I love the phone and I also would like to keep using it, I only need some answers from you guys.
My first question is, if the phone will actually let me use 4G network with my European SIM card, or will I be limited to 3G?
My second question is, If I can flash an international firmware for another carrier and another country on the phone, and if so, will I have the advantages of that firmware, like the Mobile Data Toggle??
Thank you very much for your answers.
If you install the 'Network' app you might be able to change the network type.
In general you should be able to use an unlocked P variant with a foreign SIM but you may have to activate with a Sprint SIM first.
You can't flash the international version since it's Exynos and the P version is Qualcomm CPU.
I am not sure if this model has Samsung region lock which is another thing to consider.
If I was you I would try to flash the U firmware (US unlocked) as it has the most support for international 4G bands among the Qualcomm US models. It also doesn't have all of the Sprint bloatware on it.

Thank you for your reply. I am currently using the European Sim from my carrier and I have no problems with it. I managed to get rid of the Bloatware by using Package Disabler Pro, but it still sits there somewhere on my phone. So far, the phone is working very well and other than the bloat sitting on my memory and the lack of LTE, I have no complaints.
Can you tell me if someone has tried to flash the U firmware on a P model with success?

Could you tell me how you did it, or link me a guide??
I had bought an unlocked Sprint galaxy S7 (930P) off ebay which died on me. Got it repaired from the service center and they sent me a locked device instead. The phone is currently on Software Version - G930PVPS4BQC1 and the hardware revision is Rev 0.6. I'll be using the phone in India and have a few questions.
1. I need to get this SIM unlocked from a service online. Does anyone know of a reliable place to do so?
2. If I flash the U Rom on it after unlocking it, will I lose the unlock? (I don't mind downgrading from Nougat to Marshmallow)
3. Should I unlock first then flash the ROM or flash the ROM first and then try to get it unlocked?
4. Will flashing the ROM directly unlock the phone itself?
Please advise.
...
you could try gsm zambia to unlock your phone it works i tried it myself a few days ago, also after my phone got unlocked i flash the U firmware/rom and the unlocked remained. so you should unlock your device first then flash the U firmware :good:
PS. if you one nougat better to downgrade if you can do marshmallow so when you wont have any issues flashing to U firmware. :cool

Flashing stock firmware on carrier locked phone

Hey everyone! I'm somewhat new to XDA (as in this is my first time creating/posting a thread) but I've decided this is the best place to get some help.
So, I have a carrier locked G935W8 Fido phone, and I was wondering if it was possible to install the stock G935W8 firmware from sammobile. I have read around that flashing the stock firmware works after the phone is unlocked, but what if it is still carrier locked? Can I still flash the stock G935W8? Or will I brick my device? My phone is not rooted btw.
Thanks to anyone that can help me out!
Welcome to XDA
yes, you can flash stock firmware as long as it is for the locked carrier.
Other firmware will work but the imei maybe effected.

Well, that's the thing. I want to flash the unlocked Canadian firmware, as in the one with no carrier bloatware. Will that be possible and have the phone working 100%?
I'm afraid I don't have an answer to your question, but I just did the carrier unlock on my new G935W8 a few days ago using basically the first website to come up in a google search. $25 USD; waited about 18 hours to get the code. You don't have to rely on your carrier (with their insane fees and/or waiting periods) to unlock your phone; might as well just do it. Having an unlocked phone is very handy if you travel at all.

yes, it will work for most things 100 %. volte may not work as it requires a carrier branded firmware.
you will probably have to enter the number for your voice mail manually and settings for internet as that is in the carrier branding.

Have a SM-G950FD in the US. How to run Samsung Pay

As the title says, I live in the US but bought a sm-g950fd from Pakistan while I was there. Software information tab is attached below.
How do I get to run spay in the US?
I have read a few threads about this but haven't found a definite answer. From my understanding I need to:
Backup and factory reset
Install UAE (XSG) firmware through Odin
Uninstall stock spay app and install the US one from apkmirror
Is this the correct way to enable Spay? How risky is it to flash the firmware? Will I lose OTA updates? My phone isn't rooted yet.
And in Odin, which file do i select in CSC. The one starting with Home_csc, or just csc ?
Here's what I did and got it working for me

Thanks for this. Do I need to have a foreign sim card or can it work without one?
Can I ask do you roam in the US with an international provider, or do you live here and have a US cellular provider?

I live in the US. The only way I was able to change the region is by using the method I linked. I literally everything before that, flashing different versions etc, but only by changing the Sim card did it work. Paid about 10 USD to have the Sim shipped to me. It's been a while since I did it so I don't remember the specifics, but my link is pretty detailed

Yeah, your method is very good. Any specific network to look for? And should I flash the latest firmware or a little older one?
So I managed to get an indian sim from a friend and installed the indian firmware. What happened is that my phone's CSC has changed, but it has changed to Italy (ITV). And apparently, Italy only has the single sim variant so I didnt get update to oreo as well :/
What should i do? get a sim card from another country and do the process over again? or just manually install the indian 8.0 firmware?
Samsung pay seems to work fine though
