Multi-CSC Question - Samsung Galaxy S8 Questions and Answers

Hey there everyone!
Recently, I bought my S8 out of my home country. It's an Exynos G950FD, manufactured in Vietnam. I flashed the ZTO (Brazil) firmware as soon as I could (AP, BL, CP and CSC - not Home_CSC). As it is a Multi-CSC, I was expecting it to select the CSC based on the SIM after a factory reset, but strangely my device shows "BTC/BTC/BTC". Everything works fine, apart from Samsung Pay (which I guess is kinda expected?).
Any advices are welcome! Thanks in advance.

Have you tried different sim?

[Q][I9505] CSC changed itself

hi guys. anyone experienced the same. here's what happened:
i was using i9505 glb kitkat (csc=glb=globe philippines). i flashed clockworkmod, then install carbon rom.
last month, i re-flash my original glb kitkat. then went to recovery. i noticed that the csc changed to sin (singapore singtel) without doing anything.
now my problem is what rom should i use next time i update to lollipop: glb or sin.
pls help and many thanks.
Is your phone SIM unlocked? If it is, it doesn't matter which CSC you use. Otherwise, stay with CSC GLB.
No. I used regionlockaway to make it sim unlocked.
Then as mentioned, the CSC doesn't matter. Case in point is my I9505. Originally an O2 phone, when I purchased it the S4 was already unlocked and had Ukranian firmware on it. When I installed the Black Edition UK firmware (CSC BTU) after repairing my S4's SIM tray and again removing the SIM lock, I ended up with CSC AUT (Switzerland) instead.
On an open firmware such as CSC BTU, there are actually multiple CSCs within the firmware, and all the CSC does is customize the firmware to the needs of a specific region. In the case of AUT, the firmware installed three Swiss-specific apps that could be easily removed. BTU and the other CSCs essentially do the same thing, and I am guessing this is without modifying the firmware itself.
Ok. Thanks guys. I'll still use glb firmware once lollipop is released. I had once semi-bricked my s4 (got repaired at samsung center) so i'm kinda nervous this time.

Weird CSC problem

Hi everyone,

Now I would like to know which is my original CSC.

CSC and Samsung Pay on 935F

I've read through several monster threads on Samsung Pay and the 935F variant, but I still need some clarity.
I have a 935F running TPA CSC (Panama). I am in the U.S. using the phone on AT&T.
I understand in order the Samsung Pay to work, the phone must be flashed with firmware from a country that supports Samsung Pay, like Australia (XSA).
Does "firmware" mean the CSC piece or all four (BL, AP, CP, CSC) pieces need to be from a "Samsung Pay country"?
If I flash BL, AP, SP from XSA and CSC_Home (from TPA) will I be good, or do I need to flash all four (including full CSC not home from XSA) from XSA?
Thanks.
Rene
ALL FOUR!!! or you will have a mismatch!

Find a firmware without a multi CSC I believe XSA and UK carrier firmwares all are like this.. Check the repartition box. Flash and don't use the Home CSC. Let the phone boot and then flash your multi CSC firmware. That is how I have gotten around it my S7 edge when I was trying to make Samsung Pay work.

Hey thanks for the quick reply. So just confirming before I start, you reckon below are the steps I should take?
1) Flash with a non multi-csc firmware, such as the Australian XSA (check the repartition box, and don't use HOME_CSC)
2) Reboot, then flash again with a multi-csc firmware, such as the Netherland PHN firmware.
And, when flashing do I pick all 4 files in Odin (BL, CP, AP, CSC)?
Thanks for your help.

If you want Samsung Pay works in the USA also then just flash XSA with all the files and don't use home csc and your done.
The only time I had issues is when you want to switch from a multi csc to another multi csc. Example German csc to UK csc because they use the same firmware. That is when I flashed a fixed csc then flashed a multi csc. So I could get the specific csc to work on my phone. Supposedly you can do it differently through the dialer I think. It never worked for me.
I have my s8 and my gf's s7 edge both on XSA because Samsung pay and white pages both work. Only downside is you get updates a month later then BTU.
I hope that makes sense if not pm me.
Thank you. It works as you said.

S5 Duos G900FD Baseband confusion: no update for my region/country + CP,AP,CSC differ

Dear XDA,
to get my fingerprint sensor working with Lineage-OS 7.1.2 on my S5 Duos, I want to update the baseband firmware.
Because I couldn't find any clear information of the region of my phone (*#1234# didn't work with lineage-os), and there is no firmware for my country/region, I thought I go the super-easy way to update via Kies3.
Done so, but unfortunately the baseband isn't updated, and there are no FOTA/Kies3 updates available. AP has been updated to the latest version (G900FDXXS1CQD2), but not the baseband ...
When I check AP,CP,CSC on now-stock rom with *#1234#, it says:
AP: G900FDXXS1CQD2
CP: G900FDXXU1CQA4 (as before Kies3-update)
CSC: g900FDOJV1CQB1
On sammobile.com and samsung-updates.com I find G900FDXXs1CQD2 firmwares, but nowhere they say whether it's AP, CSC or CP (the thing I need updated).
I think I don't mind the region as long as English and French is included and I can use LTE in (Western) Europe.
Two questions:
1)
a) when it says "Version" on (can't post urls) samsung-updates: is this the CP/Baseband?
b) similar on sammobile.com: There is PDA and CSC, both differing. But I need baseband/cp.
2) I understand that there are no carrier-specific firmwares (S5 duos apparently not sold by carriers?). So if version/pda is also baseband, which firmware do I download? There are 8 different firmwares with G900FDXXS1CQD2?
kind regards
1. Most likely it's AP, but CP should be the same as AP inside. Sorry, it looks like CQA4 is the latest CP for this S5 variant.
2. Most likely any if you're planning to flash modem only.
CPs will be the same.
Carrier firmwares within one S5 VARIANT and firmware VERSION differ by CSC and hidden partition size.
