How to update the firmware with Odin - Samsung Galaxy S7 Questions and Answers

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)

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.

Trying to Unroot g930aucs4bql1 via Odin

Hello,
During an attempt to recover data on the phone after a factory reset mishap, the phone was rooted by a 3rd party program.
I wanted to do a fresh install of the stock firmware but I keep getting a fail message via Odin when trying to flash the firmware from the Unroot forum.
As posted in the title the current firmware is from the December update and I cannot for the life of me find a download for it. Am I missing something obvious here ?
If your goal is a fresh start on stock firmware, don't use any customised unroot firmware files.
Just go to sammobile.com or updato.com and download the correct stock firmware for your model, and flash all 4 firmware files (CP, CSC, AP, BL).
Flashing stock firmware via Odin will undo root, there's no need to use specific unroot firmware.

Sorry for hijacking the thread but I've a question that is somewhat connected to the OP's one.
Will flashing stock firmware with Odin check my void_warranty flag? I f***ed up and my S7 constantly talks that unauthorized actions have been detected.
Stock firmware via Odin will not trip knox or any warranty flags

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

Update firmware without lose any data.

hello guys!
I have a SM-G950FD (ZTO) rooted by magisk and TWRP recovery.
I need to perform updates by flash a zip or donwload via odin.
The problem is: when I try to update a firmware downloaded on Sammobile (tar.md5) via Odin it changes my recovery causing to lose all data.
This happen because on firmware that I donwload on Sammobile have a stock recovey included. Otherwise, if I use HOME_CSC will also cause lose data because of change on recovery.
I try a lot of things like, remove recovery file from the tar.md5, also try use Abyssal Kitchen, but I can't have sucess.
I ask for help plz! I just need upgrade my firmware without lose data by flash a update.zip or donwload a .tar via Odin using a firmware that I donwload from Sammobile.
Kind regards!

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.
