Changing CSC of S9 - Samsung Galaxy S9 Questions & Answers

I realise this question has probably been asked countless times but here we go. I have a SM-G960F but it is has a H3G firmware. I want to change it to BTU. Can I flash the latest BTU build, and use CSC instead of HOME_CSC as well as other files. Like, will this work without issues?

Yes, when it boots up it will likely be in German or something, on the first screen there will be some text with two options to press, you need to press the button that (In German) says reset the device, if you press the wrong button just boot to recovery and factory reset manually
On the next boot it will be in English

Why German? And would that be on the set up? Like when you first boot and it says welcome?

Just what it defaults to before the CSC changes when you factory reset, SIM card determines CSC when you flash Multi-CSC like BTU is, but only after the reset
And yes, very first screen it shows after the Samsung logo

Okay. I've rooted and flashed stock since S5. It's because this is my new S9, I dont wanna mess it up.
Edit: Thanks alot for your reply

I did the exact same thing you're about to do with my G960F too, mine was on O2 and I needed BTU or XEU for the Pie Beta, so I flashed the exact same way (Make sure to use ODIN 3.13.1)
It will likely give you XEU not BTU, makes no difference really they are both UK unbranded/unlocked firmwares and you get updates directly from Samsung instead of your carrier

What about doing *#272#Phone’s IMEI#. Would that bring up an option to change?
That's also why I want to flash, get update for Pie faster.

No because your current CSC does not contain BTU or XEU, it is a single carrier CSC
Not sure that works now anyway, Samsung have added a lot of security additions to prevent us from playing, even to the point of not being able to update system apps via apk
Don't be worried about using ODIN, it is Samsung's own internal flashing tool in the first place, as long as you flash AP, BL, CP and CSC together and do not have any disconnections during the process you'll be fine

Once you've flashed BTU/XEU you can flash DBT (German) Android Pie using HOME_CSC and it will not change your CSC, but you'll have Android Pie, that's what a lot of us have done until the UK receives it

Wait. I wanna do this. How does it work? Like flashing home CSC for DBT doesn't change the csc, but gives pie? How would I do this?
And does this still mean when it is pushed to UK it will be available, or will I need to re-flash?

Yep, HOME_CSC will not change your CSC, and DBT is included in BTU Multi just as XEU is, so it is quite happy leaving your CSC alone
Once the UK receives Android Pie, just do it again the exact same way with HOME_CSC and you'll be set for OTA updates from XEU again
No data lost, no reset of phone, just a nice quick way to get Pie now

Installing XEU CSC defaults to ETL CSC on A520F

So 2 weeks ago I flashed Oreo 8.0.0 with the BTU CSC. Now 8.0.0 has been released for XEU, and since my device is an XEU I would want to go back. The problem is XEU is a multi-CSC and it would be more likely to install some other CSC instead (in my case it installs ETL). I bought my phone from Carphone Warehouse and I even contacted Samsung to make sure that my CSC is XEU. So how would I go to my original CSC without root?
I even tried the *#272*IMEI# code but it showed no results. Any help?

Flashing a firmware with different CSC code

Is it possible to flash a firmware with a different CSC but is from the same region as the original?
I've got a carrier locked S9. I don't mind the device being network locked, the updates are just really slow on my current network. All other carriers from my country have updated their S9 units except ours.
I downloaded an open line firmware of the same region because it receives faster OTAs. I've got Odin and the drivers ready. I'm just wary that flashing a firmware with a different CSC will brick my phone...
For reference, my S9's CSC is GLB and I'm planning to change it to XTC.
Thanks!
Should work as long as the CSC you are changing it from is not included in the CSC you are flashing, otherwise it will just default back to the phones original CSC
You will need to flash CSC and not HOME_CSC in order to change though, which will reset the phone back to factory

Thanks for this! Took the plunge and flashed the firmware... All is good so far.
Now I'll just wait next month to see if I'll still receive OTAs or flashing will be the only way to update

Hey there,
Just wanted to confirm one thing regarding changing the CSC, did you phone's Knox get tripped?, are you able to use S Health, S Pay and Secure Folder?
Need to confirm this cause I am planning to change my phones CSC, but I use S Pay a lot. A little skeptic if changing the CSC would trip Knox :fingers-crossed:

Help with flashing U1 firmware to my Verizon G960U

.
DetectiveTaco said:
I have a Verizon locked Galaxy S9 (G960U) and I want to remove all the carrier branding and crap since. With the US Snapdragon Samsung devices having the bootloader locked and preventing the ability to root or flash custom ROMs this is the only way I can get rid of the carrier branding garbage. Though there is so many firmwares and different versions of the G960U1 firmware that I don't know what to get. Or which version of Odin I need or what to do to flash using Odin. If anyone is willing to help and walk me through this process that would be amazing because there is no good detailed step by step guides or videos on YouTube on how to do it. Or they aren't recent.
Click to expand...
Click to collapse
get the patched Odin here
and the latest U1 firmware here
put the 4 files from the firmware in their respective spots, using CSC to factory reset the phone and HOME_CSC to flash the firmware without resetting.
let me know if youre not familiar with Odin enough to understand what im getting at

I looked at the firmware link and it was build back in August but I am already on the September Security patch?

DetectiveTaco said:
One last question, did your CSC change when you flashed the U1? My CSC before flashing was VZW/VZW/VZW and it's still VZW/VZW/VZW. In the phone info app it says my firmwares CSC code is XAA which is what it should be since I flashed the XAA G960U1. But then it says the active CSC code is VZW. Does this mean I will not receive the unlocked OTA updates from Samsung directly like I thought I would, and instead I will still receive the Verizon OTA updates instead. http://imgur.com/a/KgooKUR
Click to expand...
Click to collapse
it should still get updates for the OTA version. What happened is when you put the vzw card in, the firmware chose VZW since that was one of the available CSCs in the package. No worries man
.
.
DetectiveTaco said:
Or is it like because the CSC is Country/Region/Operator and VZW was a part of the multi CSC package but the firmware uses the XAA CSC code it will pull the updates from the XAA provider in this case that being Samsung.
I will probably wait until the next update for XAA devices is pushed and see if I receive it. And I'll either report back here or PM you if I receive the OTA for the next XAA G960U1 update

thats what i was driver after. the version of firmware you flashed contains several CSCs and the vzw one is what the phone latched on to. If you popped another sim in there thats within that csc list, itll probably do similar stuff with that
yeah, feel free to hit me up. if you pm me on here, i might not answer super fast, but ill eventually get to it lol

DetectiveTaco said:
Yep sure thing. Hopefully the October patch will get pushed soon and ill found out.
Click to expand...
Click to collapse
oh, forgot to address one of your previous questions. You can flash those files all you want, the nice part about them is that if youre flashing a new version on top of the old one, just flash the CSC_HOME and it will keep your phone exactly how it was but still apply the update. Its pretty sweet
.
DetectiveTaco said:
Yeah I flashed the regular CSC going from G960U to G960U1 because how it was a bigger transition and I didn't want to leave traces of Verizon crap.

very good. thats a perfect example of when to use the CSC vs the HOME_CSC

You would need to change your CSC to BTU using samkey to enrol officially in the beta, or you can just flash the latest BTU firmware with Odin, then the update.zip for the beta from recovery

Sorry to hijack this thread. Do you know if I change the CSC to BTU if I would get Samsung pay? I bought my phone from a region that doesn't have samsung pay, but right now I'm in Canada where the banks are supported.

Never tried myself, but I would assume so, I get Samsung pay on my BTU S20U, I think others have done exactly that for this reason too, you'd need to flash a BTU firmware too (Unless you get an OTA immediately after switching CSCs in which case there's no need)

Quick question since you seem to be in the UK. Do you have MST working or has it been disabled completely? I didn't know this before. That was the primary reason I was interested in samsung pay over google play. I'm not seeing anything that samsung does better over Gpay, excluding the rewards, which don't seem like much anyway to begin with.

Question How to update to Android 13 today?

Hi, I have some spare time now and need to reinstall my Fold3 anyway.
So I would like to test Android 13 and am looking for the safest way, of course without triggering knox.
Can I download and flash via Odin Indian firmware from here: https://samfw.com/firmware/SM-F926B/bit/all/av/T(Android 13) ?
Or should I register as a beta tester?
My csc code is OXM via *#1234# and EUX via "samsung phone info" app.
Which way to go, please? Or point me please in the right direction.
Thank you.
Good question, im also interested in going odin way, so i could also need a secured way
I downloaded the INU rom and to keep data flash HOME_CSC, it keeps the csc that you have now
So did I. I flashed INU on my EUY F926B. When you flash Home-CSC you will keep your data.
Is that absolutely secure that ill keep my apps and setting? Got 2 Authenticator Apps for work on it

Been there, done that, if you have critical work apps, then wait for the official update if you are not 100% sure what you are doing.
ODIN says succeeded, so im crossing fingers. Have worked with it on an older Galaxy before, but never with Firmware from another country. In CSC ive taken the HOME_CSC_OXM_F926BOXM2DVK3_MQB58858275_REV00_user_low_ship_MULTI_CERT.tar.md5.
That should be right
