Changing CSC on Korean Version - Samsung Galaxy Note 20 Questions & Answers

I own a Note 20 5G Korean version (SM-N981N, CSC is OKR). It does not have region locked sim.
However, i want to change its CSC into US or Canadian version, with less bloatware, and most importantly firmware that supports eSim
I'm not sure i can just flash different firmware (N981U1 or N981W etc).
Do i need a unlocked boot? Do i need to worried about going to Samsung jail?
Also im not really worried about warranty or other legal stuff.
Edit: I'm on Android 13, if that matters

Flashing TMO firmware onto Canadian device??? can it be done and work?

Flashing TMO us firmware onto Canadian device? Getting ready to spend a $1000 on a Canadian deep sea blue note 8. Just wondering since it's a snap dragon if I could flash 100% stock t mobile firmware on it and have it work like an "out of the box" t mobile note 8. I'm not interested in rooting(not just yet anyways). I just wasn't sure if this would be the same process of the carrier flashing we do here in the states. Flashing the stock t mobile ap/cp/csc/bl all on the Canadian device is what I'm trying to accomplish.
I don't see why it wouldn't. The only difference between the devices is the firmware. The hardware is all the same. As a matter of fact, a method of carrier switching relies on flashing the Canadian firmware onto your device and then flashing whatever other firmware variants you want. So, with that said, flashing a TMO variant on your Canadian device shouldn't be a problem at all.
I don't think you will be able to flash the American firmware onto the Canadian Note 8 without any issues. They have different model numbers (N950U for US vs. N950W for Canada) and therefore probably also have different bootloaders. The American firmware will have to be modified for the Canadian model by replacing the bootloader, CSC, and PIT files among others. A tedious process and not always a successful one.
Perhaps you will be successful but if not you can still switch CSCs with a CSC changer zip that's floating around. I've used it to switch from the Korean CSC to the Canadian CSC because I bought a Korean model and wanted it to work properly in Canada.
Check the S8 and S8+ forums...seems they have had success in doing this

Changing CSC of an unlocked S9+ G965U

Hello everyone. I'm struggling to find a starting point on how to change the csc of my phone. I haven't changed a csc before and there are lots of conflicting info on the forum. I'm familiar with Odin and flashing ROMs in general.
I bought my phone from the US, and it has the AT&T G65USQU1ARBI (unlocked) software, however, I live outside the US and I want to change the CSC. I want Samsung Pay to show me offers from my region.
Where to start?
Should I flash a different ROM straight away? and would that change my CSC? Obviously, I don't want any of the AT&T features, so I don't mind changing the ROM.
Is there a ROM that I can flash that supports multi-CSC options? The Samsung variant in my region is Exynos, so can I still change the CSC to my region with my Snapdragon S9+ ?
Thanks guys.
EDIT: Just learned about the snapdragon root dilemma. So I guess the root option will be dismissed.
I bought a s9 + G965F with csc Singapore but I use in Brazil 4G network is ok but I can not use voLTE and Wi-Fi calling can someone help me? version of the OXM operator.

Enable Samsung pay

Hi, I´m trying to enable Samsung Pay, I´m in Mexico and my phone is US version, I think the problem is CSC restriction, my phone is G965U1 and the version sold in Mexico it´s G9650, the problem is that there is no ROM for the G965U1 that has the CSC from Mexico, is there a way I can fix this? I been looking information for the last 3 days and cannot find anything.
I been trying to flash the G965U1 ROM but with the CSC and/or UserData files from a G9650 ROM (the one from the mexican carrier) but with no luck (sorry, newbie here... had to try)
Thanks

Flashing SM-G9650 (Brazil) into SM-G965U1 (US)?

Hi. I want to flash a Brazilian firmware (dual SIM) into my US hardware (single SIM). Both are Snapdragon. Reason is that I want to use the Brazilian Samsung Pay. Bough the phone in the US but I live in Brazil.
Can I flash THIS ROM without problems? Will it trigger Knox? Any loss in functionality?
Thank you all.

not possible. also, is there not a CSC for your area you can flash instead?
I don't know why these guys say it's not possible, maybe it isn't with your model. I also don't want to give you any bad ideas or anything, so use your own discretion & research.
My phone was unusable when I did this, so I had nothing to lose when I did this (It worked though).
I easily flashed my canadian note 8 with a us firmware using modified odin (must be same version bootloader).
It has warranty status 0x0 (aka, Knox is NOT tripped).
AGAIN, I'm not advising you try this with your model, unless you know what you're doing. I just want to make the information available to you.
Edit: I'm just waiting for someone to upload snapdragon beta 3 one ui 2.0. I'm going to try the same method to convert my Canadian s9+ to USA version.
Edit 2: I can confirm this method works on my Canadian s9+ aswell.

Yeah I don't think it'll work on mine, since it's a single sim phone, and the ROM I wanted was for a dual sim version. Unless of course the hardware is the same and the second SIM slot is present. I could try, but I don't want to risk it. Maybe later when Sammy stops updating the phone.

Unfortunately not. The SM-G965U1 is the US unlocked version. There are only CSCs for American carriers.

if its truly unlocked, then you should already have the U1 firmware on it. Get modded Odin and the U1 firmware, flash it in Odin and go from there. I never looked back after ditching the carrier junk on my phone
Sometime ago I did somethinh like that on my Arabian S7 Edge that I bough in Paraguai, it was Dual Sim model and i flashed ZTO CSC via Odin, and the phone was working well, but i'm not sure if the reverse works, and even the models were similar (F vs FD version) in your case u have 965U vs 9650, I would not take that risk, i thing that a korean or chinese model is 9650 too
look at this picture, US version has more bands so the modem could be different, you can try but you're risking your phone

yep, they are different phones that just so happen to use the same processor. Different bootloader, same chassis for whatever reason. Anyways, there have been threads talking about converting the 9650 to a 965u, but ive never seen anyone confirming that it indeed works. Big risk, but as long as one can get back to Odin mode, one should be good.

[HELP] Flashing my Galaxy S21 5G Korean Variant SM-G991N (CSC: LUC) to SM-G991B

Hello, I'm newbie and I just want to ask if I can flash another Firmware on my device, I'm currently on PH where s21 being sold here is SM-G991B (CSC: XTC). I want to remove the bloatwares and some samsung apps are still on Korean Language. I'm using an SM-G991N Model with LUC CSC. If possibly, I want to change it to XTC CSC, I already tried using Samkey but it failed. Should I flash the whole firmware SM-G991B on my device? It's same processor as my Korean Variant phone which is Exynos.
Hope anyone can help me. Thank you!
You will trip Knox if you try that.

It there any other way? coz Korean variant updates takes so long. OTA/Smart Switch I still don't receive the latest security updates.
Not as far as I know... Unless you want to use a custom ROM.
