Question Change region from Korea to Global (or Nordic) on S21+ - Samsung Galaxy S21+

Hello people, I hope you're okay!
I bought an used S21+ but it was not clear that the model I would receive is Korean (G996N). While I don't have any issues, it also misses the eSIM option (and probably Samsung Pay is not going to work in Europe). The eSIM option would be really good to have (SPay I do not care a lot).
I've been searching for an answer in regards to change the region and the responses are mixed and I am out of Samsung phones and firmware loop for a few years. Some say I can just change the CSC region using SamFW and that's good to go. Some say it will not work because my KOO CSC does not allow this change. Also, OTA firmwares are lost until I switch the CSC back (but, from what I understood, if I also change the firmware it would receive OTA normally).
Question: is it possible, nowadays, to just change Firmware and CSC to another region? My phone has an Exynos processor so it would have to be a firmware from Europe or Latin America.
I also understood it will not brick nor trip knox efuse, right?
Thanks a lot!

@angourakis Ok let me give you a clear response about CSCs. ALL Samsung firmware will let you flash a new CSC (as long as you use Odin). This has worked for me every single time.
You need to update your Android to the latest 13 and download and extract this (remember to use “direct download”, this website is the only one with a good selection of firmware) and use Odin (get 3.14.1 non patched) to flash the HOMECSC file (in the CSC slot).

Hey @traman124 thanks for the response!
Why this firmware in specific? I am running a more recent firmware than the one you mentioned. Also, do I need to have the bootloader unlocked?
Thanks!

It doesn’t need to be that version @angourakis it can be any version… that one will work though And you can use Odin with a locked bootloader (with download mode).

@traman124 thanks again!
Unfortunately, I tripped knox while trying to install a CSC from G996B version (kept BL, AP and CP from G996N and only used CSC from B version).
Now I am trying to look for a trade in program to replace the phone.
Thanks anyway, I really appreciate your help!

@angourakis I’m sorry….. this has never happened to me while flashing CSCs but the few times I have I did it with the same variant phone/tablet…..

Firmware change - double-check please?

Hi all,
I'm back to Samsung after a number of years away at HTC and LG! Last Samsung was an S2 and so I've used Odin, reflashed firmwares, rooted etc. before so know my way around this stuff in a general sense.
I got an S7 from CEX recently to replace my broken LG G3 but the firmware on it seems to be a slightly older / foreign one and I want to get onto a clean UK / EU firmware, so I can keep stem with OTAs that I see friends' S7's receiving. My current firmware is baseband G930FXXU1BPJE, build number G930FXXU1ZPK4.
I've looked on SAMMobile and can see two options for UK unbranded; XEU and BTU. So my first question is what one should I use and what the difference is?
Secondly, when I use Odin to flash whichever one is correct, will I need to repartition? Or will factory resetting after flash be enough to properly correct the CSC?
Finally, will this still show up as an 'untampered' phone, and receive OTA correctly?
Thanks for the help.
XEU has the most updated firmware atm with a February security patch, where BTU is still on January afaik, both unbranded UK firmwares
If you flash them using CSC (Not HOME_CSC) which will reset the phone and change CSC, then you will remain KNOX 0x0 and receive OTAs for whichever CSC you choose, XEU or BTU
No need to repartition
I did read something about needing to flash to another CSC supported by the current CSC on your phone atm (Multi CSC) before flashing to the one you want to change to, but not sure about that, I've only ever switched between BTU and XEU, and BTU is multi CSC containing XEU too

Thanks, I'll stay alert to that possibility. I'll go with the XEU variant and hopefully be ok. Just need to backup my stuff first.

Hello, did you have any luck changing your CSC without Re-Partitioning ?
Im in the same situation right now (DDE CSC, still on 6.0.1) and I am kinda scared after reading so many posts where people bricked their phones.

Flashing G930F "BTU" (UK) Nougat firmware in the USA - CSC change needed?

Since there is no official Nougat release in the USA yet, I was planning on installing the "BTU" Nougat official firmware intended for the UK. Do I need to do anything with changing the CSC to use in the USA, or just flash everything as-is in the firmware download? I don't understand if the CSC change is REQUIRED to match the country you are using the phone in, or just recommended. The current Marshmallow build is showing a CSC of OJV (middle east)
What are you USA folks out there doing? I am on Straight Talk (AT&T sim).
My current phone is giving me a lot of problems, and I'd really appreciate a response as I need to get switched over to this S7 ASAP. I realize I can just use Marshmallow but am really hoping to get to Nougat so I don't have to reflash and potentially lose data down the road.
Thank you!
If the CSC you want to change to is not included in the CSC already on your phone, you'll need to use CSC of the new ROM (Not HOME_CSC) along with the other 3 sections, and check the "Repartition" option in PIT settings of ODIN
This will wipe your phone back to factory settings
Are you rooted?

He doesn't need to check repartition. Despite the fact that it is designed for downgrading and unbricking (exclusively, in most cases ), it is not required to do that if only CSC change is needed. Only thing he need to do is using CSC section of the ROM (not Home_CSC because it is preserving old settings in the phone, message to The Founder of the topic ).
Generally, when I was switching to BTU I flashed Firmware with CSC different that BTU (for example Sweden rom) and then flashed BTU sofware. CSC has changed flawlessly
And when you have rooted phone, you can change CSC manually. That extremely ease you effort.
i would just flash the firmware and the csc that comes with it because then you will get updates in the future. if the csc doesn't match the firmware you wont ever get updates so just do a samsung cloud backup and flash the nougat But its weird that someone in the usa doesn'ty have nougat because i thought usa was 1 of the first with nougat.
RiTCHiE007 is right. If you want to receive OTA updates, CSC must match with the type of firmware it comes from. That is why you need to change CSC from US to BTU. Here is a thread that will help you out providing explanation of the topic.

J7 Prime Firmware Flashing

Hi guys! I tried posting to a different forums but no luck in replies. So, I tried to go here and find some answers.
So, Im waiting for the official update for my phone (SM-G610Y - here's my latest firmware: PDA - G610YZTU1AQF2, CSC - G610YOLC1AQF1), but Im planning to flash a new firmware. Although, since PH-OpenLine havent rolled-out a firmware nougat update, I want to use Australia's firmware (PDA - G610YZTU1BRC3, CSC - G610YXSA1BRC3).
Questions:
-Will my phone still work if I will do it? And will my device status change from official to custom?
-Should I use all four files (BL, AP, CP, CSC) when flashing the update/firmware?
-Will there be any conflicts/problems?
-If it caused a problem, can factory reset (as others said in other forums) work to revert back to the original and official status of the phone? Or will there be any solutions to rollback?
Thank you!!!
Hi
Install this software .... Phone INFO ★Samsung★
The CSC tab (page 2) will show you the compatible CSC codes for your device. I.e. installing official software from those countries should be ok.
Flashing official software won't change your status, aka trip knox
Flashing your original, official software should restore to factory state.
Good luck!
Thank you for replying and answering some of my questions.
So I decided to use Australia's firmware. I just wanna ask which one is the compatible csc? Is it the available csc from the phone info app? If yes, XSA is not included, what will be the problems when I continue to flash it (if there are any)?
And more importantly, should I flash all 4 files or just AP? And any important matters before I flash?
Thank you!
If XSA is not on the CSC list, you need to take care that the mobile networks in Australia are compatible with those in your home country - both gsm?
Also I would avoid a network specific firmware.
Any specific reason for choosing XSA?
Flash all 4 files.

How about I update using XSA and changing my CSC code after the update is finished? Will it work?
Whats a network specific firmware? Is it the one uploaded in the sammobile (thats where my firmware came from)?
And no, I dont have any specific reason for choosing XSA. I only have 3 options (NZC, VFJ, and XSA).
Sorry for being a newbie and thank you so much

If your home network and Australia use the same radio tech i.e. gsm, no need to change the CSC, just upate
Whats a network specific firmware? Is it the one uploaded in the sammobile (thats where my firmware came from)?
E.g. for Israel (ILO) is generic for rest of Israel. There's also firmware specific for Pelephone in Israel (PCL)[/I]
And no, I dont have any specific reason for choosing XSA. I only have 3 options (NZC, VFJ, and XSA).
I see why now .... Here is a faster source .... you can use a download accelerator 610Y firmware on Updato.com
Download and enjoy!

More on the network specific firmware - for Phillipines XTC would be generic (Open Line). XLA Smart and GLB Globe would be network specific.
Okay, I'll try it later. Thank you so much!

I need help to identify the correct firmware for my S7 (SM-G930F)

I bought a new S7 (G930F) at ebay. When it arrived i wanted to update to the newest firmware, but i got an error notification.
I contacted Samsung and they told me to send it in.
They checked it and told me, that they are not willing to help because the phone is flashed with a wrong firmware. I bought it as a new device. This is unpleasant.
The seller doesn't answer my messages, so i thought maybe i can flash a new firmware by myself. The actual firmware is working but it is outdated. (1. August 2018)
But how can i find out which firmware is correct for this phone? How to say if it is exynos or snapdragon?
The phone information
Modellnummer: SM-930F
Seriennummer: 5AF94C0C
Buildnummer: R16NW.G930FFXXU7CRH2
Kernel: 3.18.71-14274519 [email protected] #1
Basisband: G930FFXXU7CRH2
Android 8.0.0
Samsung Experience: 9.0
I would like to flash the latest firmware and i want to use the phone in germany. Can somebody identify the correct firmware?
Thanks a lot
What does the phone say in download mode? The ROM can be modified to lie about the model and firmware, but download mode will tell you the truth.
If download mode says it's a G930F then it's Exynos, if it says G930U/V/T/A then it's Snapdragon.
If it is a G930F then good news is you can just flash whatever G930F firmware you want over top what's on it. If it's Snapdragon then you're a bit stuffed, you can't flash Exynos firmware onto Snapdragon.
For updating it if it is G930F my recommendation would be to find out the region code for your device, e.g. from here https://updato.com/firmware-archive...act=1&r=DBT,XEG,DCO,DDE,VIA,DTM,VD2&v=&rpp=15 then download the firmware using that region code with SamFirm tool https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
Download Mode says SM-G930V
I'm doomed
Yep that's a common scam. If you can't return to seller the next best thing would be to flash the G930U firmware, which is the generic unlocked firmware for Snapdragon.
It won't give you the equivalent experience, but it will remove any bloat and give you a carrier unlocked phone experience.
You can use the same methods I mentioned to get your hands on the latest G930U firmware and update the device, but you may need this specific Odin version to flash G930U over G930V https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
Thanks. Does TMK, TFN, TMB,... make a difference when the phone is used in germany?
Should i flash all 5 files:?:
AP
BL
CP
CSC
Home
I tried and my result is: Flashing only AP was not enough. Flashing all 5 worked fine for me. I chose TMK and even LTE is working. Thanks a lot.
Glad its working, for reference CSC and Home_CSC are both CSC files and you usually pick just one. Home_CSC doesn't do a data wipe, CSC does.
But when changing from G930V to G930U it's always safest to do the CSC wipe.

Question XSG csc

Hi guys i bought a galaxy s22 ultra (S908E/DS) and i saw it now the the csc is for Arab country. i live in Bosnia (Europe) is there any way to change the csc to eux? thansk for infos
I guess you bought device is snapdragon and you needs a CSC which available on;y on exynos. If there is no issue with network then better keep as it is.
Alternatively try flashing HOME_CSC file from stock firmware of EUX, most likely it may get block by odin. In this case only way is to root device and force install EUX CSC, again I don't recommend it if their is no valid reason to change.

yes its a snapdragon model. i have no problems with network yet shoudl i try over odin to flash the whole firmware or just the home csc file? is there any chance to brick the phone because its a snapdragon variant? i ask because of OTA updates?

If you are looking for OTA, you never get Exynos OTA on Snapdragon.
You can not flash full firmware, I'd suggest to flash standalone CSC file in case you have network issue. If you have everything working related to network, I strogly suggest to NOT to mess up. Still you will get OTA when you have new update for arab country.
why i cant flash the full firmware? is it because its a snapdragon or something else? can i mess up my phone when trying to flash the csc via odin and download mode?
