Hello Glad to be here back after a few years
I've got A8+ 2018 from Singapore. Great device, I love it, but I'm stuck on XSP CSC (Singapore) for which updates are not very frequent. And that's driving me mad.
Code *#272*IMEI# is working for me and I can choose other CSC.
Fast questions
If I choose CSC from list, for which there is more up to date OTA - will phone let me upgrade after factory reset?
I saw that I can just type any CSC code (by using 3 dots button in top right corner). If I will put code, which is not on the list (probably that CSC is not a part of software) - would it work and won't brick my phone? Will I be able to use OTA after that? SER CSC (Russia) would give me Android Pie, so You know - temptation
I'm trying to avoid any flashes, but I'm only afraid of Knox and flash counters. I don't need to stuck to Singapore default apps/config. If flashing with original firmware from other region would not bring any Knox/counters related problems, I could go for it aswell...
PS: I'm not taking rooting into account at all - don't want to do that.

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.
Can anyone provide a very detail guide on how to change from Three UK firmware to BTU on Galaxy S8+ as Three UK hasn't updated Galaxy S8+ since April. I feel very left out at the moment. I would like to change without losing data. Is there a way of doing this?

Yeah I hate this too so out of date, but I am seeing three firmware appearing on sammobile everywhere else apart from united kingdom. I was actually thinking of flashing the three firmware at one stage as I'm missing out on volte but having more up to date firmware is top priority for me
I would like to keep WiFi calling. Even though I haven't used it once. Why is Three behaving like this. Did you flash BTU version after being fed up with Three lack of updates.

NOT possible...
BTU is part of the Multi-CSC OXM where MANY European CSC's are included.
If you download for i.e. the BTU-firmware, that'll be the same firmware as for i.e. PHN (Netherlands).
You'll have to flash BL CP AP & CSC_OXM on your phone; your phone will be resetted afterwards.
The DEFAULT CSC for OXM is XEU. Your phone "sees", that an UK-SIM is included and will "switch" to the best CSC for your device, which is in this case XEU. You won't get BTU on your device...
I'll lose my data with XEU won't I

If you change your CSC, you'll ALWAYS lose your data...
Also worth noting that to keep Volte/WiFi Calling you would need to use the Three Firmware (H3G) as the OXM CSC firmware does not enable it.
I'm a Three UK customer and have tried many times to get Volte/WiFi calling working on XEU (OXM Multi CSC) with no luck. Only works when I use H3G firmware but I hate the crappy branding so sacrificed Volte for no branding.
I flashed from vodafone uk to btu but as someone said you get xeu. Updates are fast I had 3 already.

I flashed the OXM firmware from henklbr's thread, but used HOME_CSC from the last H3G firmware to keep WiFi callling

Latest update was pushed this morning on 3UK
Good one

Just need to wait until we get August update. Probably won't be till November/ December. I hope when Beta for Android O is released. We will be able to join in on the excitement
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.
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…..
