Hey guys,
I know this is a question that has been asked many times before and I have searched the forums for a clear answer, but I just don't seem to get the puzzle pieces together.
Basically what I want to do is change my CSC from LUX to DBT without rooting my phone or tripping Knox.
The reason I want to do this is to receive quicker updates, because right now I'm still on the november patch... (G955FXXU1AQK7)
This is a EU-model, with an Exynos processor.
*#272*IMEI# does not work for me.
My current CSC is LUX/LUX/LUX
After some research, I figured out that I need to have a Multi-CSC OXM (That's a firmware package with multiple CSC's, right?)
So these are my questions:
Where do I get a Multi-CSC OXM?
What are the steps I need to take in order to flash this firmware? (Odin?)
Will my CSC remain on DBT after I receive new OTA updates?
Thanks for tying it all together.

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.
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.
Hello,
I have been trying to find an answer to my question or a solution but all the results I found on XDA are Snapdragon model oriented.
My question is about changing the CSC just to be able to receive OTA updates faster ( I don't want Samsung Pay ..) . I aleady know that the product code is hardcoded into the phone I just need to change last three letters of the CSC.
My rom is part of the OXM multi-CSC rom, I flashed it and tried the famous code to change the CSC region but no results so far. I also do not have any other sim card to trick the phone after factory reset.
Could anyone please help ? has anyone been able to change CSC via odin ?
Regards.
Can anyone help please ? is my question a little bit confusing ?

Changing CSCs isn't possible without root or without a local SIM card from the country whose CSC you want to use.
If you're so eager to get faster updates, just flash them with HOME_CSC_OXM as they are released, you won't lose your data and you'll be on the latest OXM builds as well.

Hi
I raised this in another thread but realised the title might be misleading so I have deleted that post and ask it here.
I have at last just received my Note 20 Ultra SM-N9860. I see it is the Taiwanese BRI version.
I have tried to read as much as I can and it appears that it may be a good idea to switch to the TGY firmware as there may be some benefits over BRI.
If I understand correctly, I can do this via Odin using all the elements (using CSC rather than Home_CSC). I know this will do a factory reset but that is no problem as I have not set the phone up yet.
If I do that, I will not trip Knox and I will get TGY OTA updates in future.
Have I understood that all correctly? Have I missed anything?
Sorry but I also have another question. What is the difference between using Odin to change the complete firmware to TGY and using Samkey just to change the CSC? All the files between BRI and TGY appear to be identical, other than the CSC. Does it make a difference over whether I get the TGY OTA updates if I only change the CSC?
Is there a disadvantage to using Odin as otherwise why do people pay Samkey when they could just use Odin for free?
Changing BRI to TGY is safe. But you will not have any benefits. Instead of this, changing to CHC gives you voice recorder etc. This operation keeps knox intact as well (actually, knox is tripped only in case of bootloader unlocked to load non-Samsung signed images).
Samkey will not change CSC in your case (you'll loose your money), so the Odin is the only way.

How is the CSC selected in Odin if Frija downloads the exact same CSC files for both BRI and TGY inputs??
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…..
