Can I flash a ROM from another carrier? - Samsung Galaxy S9+ Questions & Answers

Hello guys, so I've seen that Android 10 was released in France, but not with the XEF or SFR CSCs. Can I still flash the other ones and change the CSC afterwards?
My carrier is SFR, if I flash a BOG ROM, it won't read my SIM, right?
Thanks.

if youre on the G965F and want 10, youd need to flash the multi CSC version of 10 available for your phone. It should work with your sim regardless of which one you flash, just might not get the best signal is all. Matter of fact, yes, you could flash whatever firmware you want then your specific CSC and itll be fine

[Q] CSC

The problem is the following the S2 go to assistance again but this time to be exchanged for a new one.
I am with the following problem, the S2 was Vodafone Branded (PORTUGAL) i unlocked and I installed the rom TPH ( portugal carrier free) and the problem is that now install either 2.3.5 or the new ICS vodafone and even doing factory reset he did not let me select the CSC TCL (Original one) says must always be three chars.
If I can help would appreciate, and there is a possibility of making a vodafone Sim Lock again?
Greetings and thanks
I think I can translate what you're asking.
1) did you actually sim unlock? Or just flash non branded firmware?
2) are you actually trying to flash a rom with your csc in? They don't all have every csc.
3) if you have flashed an unbranded rom you won't be able to flash vodafones csc. Just find out what the generic Portugal one is and use that.

1) yes i did sim unlock
2) my phone was branded Vodafone (CSC TCL) and i Flash the TPH (carrier free)
3) I need to put back the original CSC because my s2 go to samsung to be exchange for another one
In that case you need to check out Odia's (I think) thread in development and download your appropriate carrier branded firmware. Then just hope they don't notice your sim is unlocked.

Need some help with unbranding

Hi guys I have just got my Samsung Galaxy edge and its branded to 02 UK and I am going to unbrand it I wanted to know which Stock should I flash BTU OR XEU also will I need to change the csc ?
Pretty sure XEU is Europe unbranded (including UK) and BTU is just UK unbranded, flashing one of those should set your CSC to the version flashed. I have always flashed BTU
Sammobile actually has XEU listed as Ireland, so prob best go for BTU http://www.sammobile.com/firmwares/database/SM-G925F/BTU/
Thanks MrC85 thats what I have done just flashed the United Kingdom BTU its all set now........Do you reckon I just get the android updates quicker now ?

I guess so, I tend to root mine etc (or use a custom ROM). so have to flash updates manually.

Flash a different Region

I know the question has been here before, but i dont seem to find a answer on my specific question:
I'm the Owner of a Galaxy S9+ - It's a "NEE" region
I want to flash the German (DBT) region firmware. Will this mess up the phones KNOX? It's official firmware from Sammy
Flashing a different region firmware, will this mess up the "modem" regarding the bands and etc.? I live in Denmark
I wish you all to have a great day out there
You can flash dbt version with no problem! Knox will not be affected and your csc will be nee !!!

Hi mate
For what i know you can only change the CSC to those CSC's available in the current ROM installed in your phone , An U variant is the snapdragon version for USA (?) it will not have a european CSC available .. and you cant flash an european rom either ( exynos).
So no , no luck to change to a european CSC with the U variant , sorry

Question Help changing CSC code - flashing BTU keeps DBT CSC?

Hi, I have a new A52s, I bought it off Amazon, and didn't realise it was a grey import. It works fine with my provider (iDMobile in the UK), apart from WiFi calling. iDMobile say the problem is because it's German firmware (DBT CSC), so I started reading up on how to change this. All of the tricks using the phone dialer codes no longer work, so I downloaded the UK Unbranded firmware (BTU CSC), and flashed with Odin. However my phone remains as DBT. I ran Phone Info, and that says that my current firmware is only DBT CSC, with no others available. I did read somewhere that you could get a CSC change if you repartitioned with Odin while flashing. Does anyone know if that's the case? Or are there other approaches that I need to use to change the CSC?
I'm afraid I don't have an answer but I have the same question.
Am looking to buy an A52S 5G primarily as it's supported by my carrier for Wifi calling but carrier price is extortionate.
Flashing carrier firmware worked before on an old S7 but I'm not sure about doing the same on an A52s 5G.
How did you get on OP ?
I'm in Australia with a Taiwan BRI csc a52s.
Wifi calling never worked on android 11, but now I've updated to android 12 and wifi calling is working with my australian telstra sim!
Hopefully this means wifi calling is no longer dependant on csc.
What happens when you flash different csc firmware with odin?
