Odin stock firmware didn't completely wipe data

I had recently flashed the DBT (German) firmware because it had the October update. Immediately after I did that, I started having problems with my VOIP app I need for work so I flashed the old BTU firmware back. After flashing, I noticed German was selected as the default language in the startup prompts, the "MeinGalaxy" app was still installed, and the Samsung Phone Info app reported my CSC as DBT (even though it reported the CSC firmware as the BTU version I just flashed.)
Pretty confused as to how this could happen. I just flashed TWRP, wiped everything, then flashed the BTU firmware through Odin again.
EDIT: It did it again! Where the hell is this old CSC data hiding? I just formatted the data and system partition. Wiped everything but my SD card. About to take the SD card out just in case but this is weird...

Flashing with ODIN does not factory reset your phone. Just boot into recovery and do the factory reset afterwards.

I just did. Wiped everything with TWRP, re-flashed with Odin and this German crap is still on here. Maybe it's in the Android folder on my SD card is all I can think. About to format that too and pull it out.

I just re-wiped from TWRP again, re-flashed through Odin, did a factory reset from inside Android, then booted to stock recovery and did a factory reset there. I'm still on the damn German CSC. Even stock recovery said something about multi-csc: DBT when I booted into it.
How does this even happen? Where does CSC live that nothing seems to wipe it?

Maybe you have downloaded a firmware which includes that bloatware. Download and flash a new unbranded firmware.

It is unbranded. BTU downloaded from updato.com. I had flashed it previously (before I flashed the German firmware with October security update) and it didn't come with this software. Also, it just doesn't make sense that stock recovery and Samsung Phone Info app are showing German CSC code.

Actually, just saw in the Samsung Phone Info app that this BTU firmware is multi-CSC. I tried to change it but it needed to factory reset and TWRP couldn't do it because the device is encrypted. I still don't understand where it's stored to default to DBT (Germany) instead of BTU (UK.) Last time I flashed this firmware, I got BTU but ever since I flashed DBT, that setting seems to have stuck.

Did you already try re-flashing without SD card in?
I remember, in my Note 4 days, I had the same problem. Flashed several times new unbranded FW, but without the CSC changing.
Then when I flashed without inserted SD card it worked and I got the new CSC.
Might be coincidence, might have a reason, I really don't know...

You could do it in settings, TWRP or there should be a option in Odin (not 100% sure)

Did you ever get this fixed? I'm having the exact same issue....

I just flashed Turkey firmware and got XSG instead (another Multi-CSC ROM with like 20 different CSC codes.) Pretty sure you will need root to change it and there should be apps available. I know there is a CSC selector zip in the Roms section that will let you put flash any CSC even if it doesn't come on your ROM.
The CSC data is in /system/csc. You can see everything that comes in a multi-csc ROM. I'm pretty sure you need to change files in there to select which one it uses. /system/csc/sales_code.dat is a text file that tells you what you are currently using.
EDIT: Found instructions on how to change CSC in multi-CSC ROM on Note 4 but was linked to on top post of S7 CSC Selector tool: http://forum.xda-developers.com/note-4/help/guide-to-change-csc-root-rom-multi-csc-t3017207

Did you finally get yours fixed? I had forgotten to do a reboot and cache flash which once completed fixed mine.

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)

Flashing only AP File

Hi guys
i got S7 930FD XSG,
Rooted using this Method [Recovery][Exynos] Official TWRP for Galaxy S7 (herolte)
Somehow mistakenly Turned off OEM
Device locked, Reinstalled Stock ROM using "Smart Switch"
Again rooted by above method.
Now OTA updates aren't available.
So I have two question, actually one confusion and one question.
As when i reinstalled ROM using Smart Switch, in Smart Switch it says "930F" instead of 930FD, while is device info it say 930FD.
1. are there same or single system/OS for both version ?
If yes, then can i install ROM of 930F XSG, with same AP and CSC of My device, i am attaching screenshot to share more info...
View attachment 4057525
View attachment 4057526
2. If answer to 1st question is yes and safe, then can i just Flash only AP file, leaving BL, CP, CSC etc ?
I just want to get latest update (either via Odin or OTA)
Regards

No help ??

Have a look in download mode what it says the device is, flash all 4 part of the ROM using ODIN 3.12.3
CSC will reset the phone
HOME_CSC will not
If you are upgrading or downgrading Android versions, use CSC to avoid problems

G930FD uses the exact firmware that G930F uses. So yes, they're the same.
Flash BL, AP, CP and CSC file (not HOME_CSC) if you want to return stock and have OTA updates. Remember this will format your phone. It's later up to you whether you want to root again or just remain on stock.

S7 G930F stuck on odin "Get PIT for Mapping"

My G930F has Poland (XEO) Stock firmware with no root at all.
I am trying to install via odin Brazil (ZTO) Stock firmware using 3.11, 3.12, 1.85 but stuck on Get PIT for mapping and stops itself.
I am afraid to do something because I have just this phone like softbrick.
Does anyone knows how can I solve this, please?
I heard that I must put in odin bl, ap cp from XEO but the home csc ZTO.

You should be putting all 4 ZTO firmware files in, there's no reason for needing to use a mix of files. The 930F is the same world wide, you're not limited to using firmware from the origin country and it's probably what's causing you problems.
Also if you're flashing AP, you may as well flash the normal CSC and not home CSC. You only really use home CSC if you don't want to data wipe, but you're going to data wipe from AP anyway.

Flash this firmware (newest ZTO) http://updato.com/firmware-archive-select-model?record=578B0E548EF711E7963AFA163EE8F90B with all options BL,AP,CP,CSC with Odin v3.12.3 or newer. Be sure in CSC section flash CSC file not HOME_CSC

At the first I did what you said here but with home csc. I will do again with all 4 and csc instead home csc. Thank u very much.

I am downloading to try. Thank u very much.

I downloaded the file and I did what u said but nothing happened.

what is the difference between flash CSC file or and flash HOME_CSC ?

Csc you will reset the one is already in your phone. Home csc will keep your csc and data, I think.

CSC resets the phone after flashing, HOME_CSC does not

Downgrade of security patch without wipe Galaxy S7

I want to downgrade my galaxy s7 to a previous security patch in nougat without lose my apps and data. I read that I have to use CSC_HOME file to flash without wipe the smartphone but I don't know if I have to flash the CSC_HOME file of my current rom or the file of the rom that I want to flash (sorry about my english xD)

If you have TWRP, make a full backup first.
The HOME_CSC is part of the zip file when you download the stock firmware, you can get it from sites like sammobile.com and updato.com. It comes with 5 files, AP, BL, CP, CSC and HOME_CSC
