How to change CSC with no wipe? - Samsung Galaxy S7 Questions and Answers

I have been searching around and haven't fond any clear answers around these questions. I have an exynos S7 and I want to change my CSC to the XSA (Australia version)
My understanding is the way to change CSC is to flash a stock firmware with the CSC you want.
- If I flash the stock rom will it wipe my data? Do I need to have "repartition" unticked to keep my data?
- Do I have to flash a newer firmware or can i flash the same/earlier firmware?
- In fact, can I just flash the XSA CSC without the rest of the firmware?
Many thanks to anyone who can help.

You don't need to flash stock firmware to get another CSC, just download the specific CSC zip flashable and flash or use Multi CSC flasher via TWRP

Thanks but I should have clarified, I want to keep knox untripped.
Do you know if stock rom flash with a new csc will cause a wipe?

[Q] How to change CSC to branded 920F

Hi, first flashed french 5.1.1 and now that vodafone has released the branded 5.1.1 want to back to stock (ATL) but when flash the sammobile package the csc changes to SIM (vodafone slovenia) and there´s no way to change the csc.
I´ve reading a lot and seems the ATL package is multicsc and flashing defaults to SIM. and there´s no possibility to change csc because cant root 5.1.1
Im totally stuck. Why want the branded? the operator customization and VoLTE activation.
Thanks to all
Do a factory reset in the bootloader, boot up and then flash the operator rom again
*#272*IMEI#
Tried flashing, boot, wipeall twice, flashing wipe data and cache but the multicsc stays as SIM csc...
*#272.... doesnt work in this devices.
tried to downgrade to 5.0.2 and root to change manually csc but the bootloader is upgraded keeping downgrades.
the only hope is pingpongroot or anyone can root 5.1.1 without tripping knox
Bring your S6 back to Samsung for official ROM flashing back to stock.
Only way to change CSC is to root...

Not true. I did it several times on unrooted stock devices.

Yes it is True. Please read the 1st post. OT described his problem as flashing the French 5.1.1 from his previous 5.0.2 ROM. When the 5.1.1 version of his country came and he flashed back using the ROM from Sammobile his CSC was changed. I encountered this same problem. My S6 is unrooted. Only way to change CSC on unrooted device is to root. I tried the methods above and did not work also.

Did you let the phone boot completely after flashing the new firmware and then do the wipe from recovery?
Yes I did. My unit is G920FD from Philippines. Downloaded 5.1.1 Globe Philippines (CSC:GLB) from Sammobile. After successful flash via odin with Full wipe at recovery the CSC defaulted to THL (Thailand). I tried all Phillipine-based 5.1.1 ROMs from Sammobile and flashed them all (3) with full wipe at recovery each time but sadly still CSC is still THL (Thailand).

You could try without a simcard (flash, boot up, wipe in recovery) or a different simcard. I never manage to change csc either in 1 go and the results can be different, eg sometimes I get Vodafone apps installed and sometimes not....
Will try it without a SIM card. Thanks.

Did this work in the end? I've got exactly the same issue except my CSC is stuck on SIM (Slovakia) when I want it to be UK

I also tried it but couldn't get it to the correct CSC (VDF in my case) either, I can do it with other packages and get it to PHN (dutch)

I have had managed the csc change also with odin, fw flashing. BUt it took at least 10 flashing, but did it.
please note, that I have had issues after ANY of XEF firmware flasing. After XEF fw, I was very difficult to do this odin flashing method succesfully. BUT it did.
but I cannot rememe what was the sequence of this procedure. I was using 5-6 different ZIPs from sammobile.

do you have ANY idea how you did it? Are you actually sure you changed the CSC without rooting the device on a firmware that was multi CSC?

i have flashed the XEF. and that was wrong. esspecially it broke the spo2, and stress measuring... I would go back to another, BUT after XEF, I always had flashing interrupt in the HIDDEN file stage.
But after I have found a flashable FW again ( maybe SER or SEB) I was able to flash XEH, or BTU. and it was changing the XEF to SEB OR SER after wipe in recovery.
The only rom I will never flash againt is XEF.
ps: i never root this 920F

Now I was able to reproduce it twice!!! :
How it works : on devices where dialer NOT shown up CSC changer (e.g.: GS6920F) :
Go to recovery, Dial up, Home + Power
wipe cache and perform a factory reset
next is important : power down the phone. NOT to reboot.
Power on in download mode: volume down+home+power buttons
FLASH for example : BTU :
G920FXXU3COI9_G920FBTU3COJ1_G920FXXU3COI9_HOME.tar
after reboot, it will be English, and If U go to recovery it will apply BTU.
Hope it helps
p.s.: It wont works with EVERY Firmware. don't know WHY. For example :
I wanted to flash after succesfully changed the CSC from TPH to BTU, so I wanted to flash XEH....BUT that resets to TPH after XEH flash.
So at least to BTU it works specially if you are in TPH CSC !

Question using AP,BL,CSC instead of Home

Hi I usually download from sammobile where they have one file and I select ap it does everything itself. However I have downloaded from updato website it has given loads of small files like ap, bl, csc.. Do I use all them for the upgrade on odin or can I just up the ap?
the files are like the following: BL_G935FXXU1DQB3_CL10422490_QB12410567_REV00_user_low_ship.tar
my version on my current phone is g935fxxu1bplb
Thanks

Do NOT select the regular CSC file that starts with CSC in its name, as that would replace your CSC and thus would result in a factory data reset of the device.
Click on CSC tab and select the firmware file starting with HOME_CSC in its name

You need to flash all of them (bt/ap/cp). Regarding the csc: if your csc is equal (or included in case of multi-csc roms) to the one of the rom you are going to flash (meaning: you have installed a BTU rom and you are going to flash a rom with the BTU csc) then use the home_csc as it will update the csc to its latest version without making a factory reset. If your csc doesn't match with the one of the new rom then you either use the home_csc of your actual rom or use the CSC file (bot the home) of the new one (this will factory reset your phone so backup first)

Hi
No all countries CSC are available yet , probably in the next weeks they may that is why there are not many choices yet
Flashing CSC thru Odin on top of rom.....not to sure about that
Did you check his thread about CSC? , hi has a tool to add different csc's maybe your country is already there ( pick the one for Nougat
If is not there and you must have it ....i would flash a stock rom with the desire CSC , install recovery again , flash Superman rom again and this time tell to keep your current csc
Remember if you use a MM csc on a N firmware some thing may not work like VoLTE
I just Odin flashed home csc from the latest sample for my carrier .... the latest I had already previously used on stock b4 flashing superman rom.

[SOLVED] Different CSC Flashing

EDIT:Yes We Can Simply flash Firmware with ODIN
hi everyone
I've s6 g920fzkvia and currently no Nougat available for my cell.
I wana flash it with XSG firmware ..
In phone infon compatible csc are VIA,XEC
Can I flash XSG?
If yes, how?

If I flash another country's official rom using stock recovery, will it change my csc

I'm planning to flash a Germany CRC7 ROM but my CSC is not german. Will there be any errors in stock recovery or will it just change my CSC?
I remember flashing CRB7 from a thread here using stock recovery and I don't know how that didn't change my CSC. Any help is appreciated.
My phone is unlocked by the way.
