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

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)

Sorry I've mistaken you with another user I think, but I STILL neeed your help mate
Finally fixed the issue. I just had to let the AP file load even though the widnow said it was not responding, aslong as i didnt click on the window and make it freeze, it eventually settled in there. along with the CSC files bl.cp. etc/ Thanks for this life saving info you've got going here guys
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
I would like to update the firmware of my S7.
After root with Magisk, the OTA-updates didn't work.
With Odin it's possible to flash HOME_CSC or "normal"-CSC.
Which CSC should I choose? Is it necessary to flash TWRP ones more (without delete the internal storage? e.g. https://youtu.be/UqwpAvT75ho)
Can I flash only the CP file (from original Samsung S8 pie firmware) with Odin (without BL, CSC, AP)?
Just want to update the modem only without losing everything on the phone.

Yes, what you are trying to do is frequently done by Samsung users. You can extract the modem from the firmware and convert it into an Odin flashable .tar.md5 then flash it via Odin in the AP slot.

So i downloaded Samsung firmware from Sammobile and i got these 4 files:
.BOOT_S7580XXUBOA1_REV00.tar.md5..CODE_S7580XXUBOA1_2814721_REV00_user_low_ship.tar.md5
.CSC_OLB_S7580OLBBNK1_2799949_REV00_user_low_ship.tar.md5
.MODEM_S7580XXUBOA1_REV00.tar.md5
Someone can explain where do each of these files belong to in Odin and I would be super grateful if someone could show me how to flash it by flashfire
you should have 5 files. 2 of them are nearly identical, CSC and HOME_CSC. Odin with files loaded
the only weird part is the CSC vs HOME_CSC. HOME_CSC will not factory reset your device, whereas CSC wipes everything
