[Q] Flashing to XEO (Poland) firmvare + changing CSC with Odin?

Hi, I want to flash my galaxy as fedup with waiting for updates.
I got BTU, UK unbranded, unlocked S4
I am polish, so thinking flash it to polish firmware as they get it fast.
GT-I9505 XEO I9505XXUBMEA thats the one I want go for
Can someone tell what is it ? is it network firmware or unbranded?
I would go for it only if I can change CSC code to XEO, so I can get OTA updates.
If not I will keep waiting for BTU
And Dont really want XEO polish carier firmware, as I can flash to Three UK BTU network, would be the same and dont have to change CSC.
So, main questions are
What it is XEO ? what network ?
Can I flash it + change code to CSC all safe?
and how to do it ? Odin
Thank You.

as far as i tried you cant change csc with flashing . unless you flash single csc not multi.
only way is to root with auto root than change csc wit csc changer and then flash desired firmware with odin.
xeo looks like it is simfree so its just general for poland

i didnt find any searching on net so i guess no. they usualy pack 20+- csc together
there was some talk of chcnging csc with flashing twice with odin without auto reboot. but that didnt work for me.

Can someone help me out as I am new to all of this...
I am using a Samsung galaxy tab 7.0 (p2610), and I flashed a jelly bean update successfully using odin. I am not rooted.
I have a system update in the notifications window that is stuck there, that is not working (process fails), this is due to the csc code being in great britain.
I am in Canada, I have Odin ready to go, can someone please show me how to change the CSC of my device to Canada?
Where do I go to download the appropriate file? After I assume I load it up in Odin with device in recovery mode, and flash using the "CSC" option in Odin correct?
Any help would be great.

Hi, try @Tkkg1994 CSC utility zip , you'll need TWRP to flash it, it has a huge range of CSC's to choose from:
[UTILITY][CSC][21.09.16][SM-G935F/FD/W8] Flashable CSC Selection V1.7

Download the latest firmware for your region
Extract PAK version download with 7-zip and copy the CSC
Flash firmware for your region BL/Ap/CP/CSC_PAK (the one extracted earlier) from PAK firmware
Only add the CSC from PAK firmware
Your device will be wiped.

Yes its simple root your phone with autoroot and install SAMSUNG INFO.APK file and use the CSC CHANGER tool to change the specific CSC and click on the install button and its Done
Note please backup your data before doing that your phone will be reset after doing this

Hi, I had a G928C with the same issue only the difference was I needed to migrate from PAK to XSG. So, what you need to do is, download a PAK firmware from sammobile and a BTU firmware (BTU is for the UK region). Flash BTU first and then right after a factory reset and then flash your PAK firmware, don't forget to do a factory reset otherwise your old csc will remain intact and don't root your phone please. Don't void the warranty.
The problem actually is most of the firmwares out there are MULTI-CSC so, your old CSC always remains intact, BTU on the other hand is a single CSC firmware so, your phone is forced to change it's CSC as there's only one CSC available when you perform the reset. So, when you'll flash the PAK after BTU your CSC will be changed to PAK from BTU.
So, you gotta do this XSG->BTU->PAK
And I repeat, please don't root your phone. There's no joy in that unless you really want to do something that actually requires a rooted phone.
Best of luck
P.S If you are able to get Factory firmware of PAK that would be great. (The one with separate CP,CSC,BL etc files with PIT as well).

yes, but need to back up your data, contacts and pictures. Changing the csc will restore your phone to factory settings.
Whats the complete procedure? I tried with PAK firmware SM-G935FD but it failed. PAK firmware SM-G935F has old may patch thats why cant install this also. Tell me something.

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.

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?
