[Q] CSC Codes and the meaning?

I am just wondering if I9505OXXAMDC means that any CSC ending in AMDC is compatible, or I need to look for that specific one?
What is relevant and what not in the CSC naming?
CSC = Country Sales Code
There is no problem with flashing or if you want you can change CSC every day via Phone info

Trouble in CSC change and stock roms

Hello!
I have read many foryms on how to etc etc and my problem is as follows. I bought a Samsung Galaxy S5 from an online store and later it upgraded from 4.2.2 to 4.4.2. Appears to be genuine but it is the SM-G900H with the octa-core Exynos. I bought it in Mexico. But the csc is TPA, meaning it is from Panama. I live in the EU so I searched for CSCs for my model in europe and decided to go with Russia's one. Got the .md5 file and started flashing normally with odin3. It always fails at 99% when it tries to flash the hidden.img (unfortunately have not any image atm). So I thought that it has to do with the CSC code. I tried every way possible that were suggested on many forums starting with rooting, but nothing worked for me, not the apps suggested, not secret codes, nothing. Cannot change the csc code from TPA to anything. Although, after I try to fail instal the SER (Russian csc code), I flash CWM recovery and upon connecting to Kies3, it recognizes the version of the PDA correctly, but the csc code is still TPA (Panama). Now I try to flash official samsung ROM again from Kies3 for a fresh start. I would like to know if there is any way of overwritting this CSC. Thank you in advance.

Try to flash single countries csc instead of multi, flash again multi country csc if you want to change it to specify region.

If I understood correctly, you are saying that I should Flash again with TPA (Panama) firmware and then flash again with the SER (Russian) firmware?
I will try that tomorrow and will be back with the results.

So I tried doing that, succesfully reverted to official PTA, but unfortunately with SER it always stucks on hidden.img and fails immediately.

S8 multi CSC Firmware question

Hello,
Can someone please try to explain this to me:
When I flash a multi CSC firmware on my S8, from the same region as my original firmware, how will the phone decide with CSC to assign from the multi-CSC list?
Example:
I have an S8 from Vodafone Romania and I want to flash the Romanian ROM firmware. But this firmware also contains other European unbranded CSC codes.
On what basis will the phone assign ROM as CSC to my phone? Based on the SIM card?
Many thanks.
No matter.
I have reflashed my branded Vodafone S8 with the open firmware for Romania. After, did a wipe cache and factory. Then the phone asked me to accept another reset to apply features from my sim card. Done that and the CSC is now the one from my country ROM. So, short answer, keep the sim card you want the CSC for in the phone to have specific settings

How to change CSC from XAA to TCE?

I bought a S8 + originally from Verizon. Then installed firmware unlocked (SM-G955U1) then the CSC automatically changed to XAA (usa unbranded).
I am currently using it in Mexico with Telcel. Everything works good, samsung pay does work, but I want to active VoLTE and use carrier ID anti spam there's no option to activate that because my CSC is not TCE, the problem is that the firmware is not SM-G955F (exynos version) that includes TCE (telcel México) CSC which allows to go to a specific setting menu to activate volte and ID anti spam.
I'm almost sure it is not possible changing the CSC because proccesor firmware incompatibility Snapdragon (SM-G955U1) and Exynos (SM-G955F).
The question is, can I change the CSC that comes with firmware U to a CSC that is supposed ONLY included in firmware F (exynos) ?
And how to do that?
