Galaxy S7 firmware flash question - Samsung Galaxy S7 Questions and Answers

Hello everyone,
I just flashed the Nougat update to my SM-G930F and I just flashed the AP File.
Do I need to flash and the CSC and the BL files ?
Thank you

Normally you should flash 4 files in the same odin session. Ignore the home_csc file.

You should flash all 4 files in their corresponding places. Just leave HOME_CSC and just use CSC

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...

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.

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

Can I flash modem only with Odin?

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.

[SOLVED] [QUESTION] What does Boot, Code, CSC_OLB, Modem mean?

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

Oh thank you i already know that btw in the mean time i have try Boot one with BL and walla well Boot is BL. This is new comer who downloaded from Sammobile or Samsung Firmware Downloader:
-BL=BOOT
-AP=PDA=CODE
-CSC=CSC (two type as the mod mentioned)
-CP=MODEM
Case closed.
