Can i flash stock firmware with sligthly different baseband version?

So i decided to unroot my phone today, and the only firmwares i found had different baseband versions than that of my phone.
My question to you is if it's dangerous for my phone if i flash a slightly different baseband version firmware?
Phone: Samsung Galaxy S6
Android Version: 5.0.2 Lollipop
International version (SM-G920F)
Country: Sweden
Baseband Version: G920FXXU1AOCW
Custom root: CF-Auto Root for said device
Link to firmware availible for my phone (Sammobile): www .sammobile.com /firmwares/ database/ SM-G920F/ VDS/ (Assemble link)
The baseband version of the firmware is: G920FXXU1AOCV (Has a V at the end instead of W)
Will it damage my phone if i flash the firmware that has a V instead of my phones W at the end?
Thanks in advance

i dont't think so. As long as it for G920F devices,it doesn't matter what the baseband version is or in what region !!
cause i tried on my own device, bro

[Completed] Rooting Samsung S5 Duos (SM-G900FD)

I have Samsung (SM-G900FD) with Lolipop(5.0) and I want to root it without tripping the knox. I have been searching the internet for past couple of days and I have found a way. It involves, among other steps, downloading and installing the "towelroot" apk, but here is the problem. Towelroot method does not work with Lolipop and I have to downgrade the software to Kitkat(4.4.2), the software version my phone came with.
Once again I have searched thoroughly to find a way to downgrade to Kitkat and I came to the understanding that I need to download official KitKat firmware from sammobile and install it manually, but I don't know which firmware to download from the list that appears against my phone's model.
I have following questions:
1. How will I know which firmware to download from the list.
2. Once I have downgraded and rooted my phone, can I upgrade to android 5.0
Here is my device info,
Model Number: SM-G900FD

But it is a Verizon phone. Device type, and product name are zerofltevzw that's Verizon. Also, whatever it says in download mode, that's what model the phone is.

OK if I were you I would go to sammobile official site and download the official latest firmware for the Verizon S6. Also, I'm assuming you checked in adb by typing "adb" devices. To make sure the device is hooked up correctly.

Not really....and if i shud ask...what is it abt checking in the adb by typing "adb" devices....how is it done...
U have to have adb and fastboot installed. You just hook your phone up to the pc and open command prompt. Type adb hit enter, type adb devices hit enter. Should show your device status

@BobbyJanuaryBoy DO NOT TRY TO FLASH ANYTHING ON THIS DEVICE, EVEN ROOT!
Your phone is actually not "manufactured" by Samsung. It has Verizon motherboard, but the software inside is a firmware for international devices but modified to run with other motherboards (like Verizon), and a modified modem software and a unique IMEI & SIM lock storage.
You can only flash Verizon firmwares on it, BUT if you flash, your phone will be SIM Locked and you'll have some network issues due to unique IMEI & SIM lock storage and it is not revertable.

I'm pretty sure about that, sorry.
Same problem. Is it possible now to flash a Verizon Custom rom, without having any network issues?
Same here. I bought this phone few days ago and just discovered it was bootloader locked. Another thing is that I realised it kept on 4g signal even when the network drops to "edge".

//ATT G950U\\ Stock Odin Files Firmware G950USQS3CRE2

Stock Oreo G950USQS3CRE2 Odin files for AT&T S8
Model: SM-G950U
Model Name: Galaxy S8
Country: USA
Version: Android Oreo 8.0
Security Patch Level: May 1st, 2018
Product Code: ATT
PDA: G950USQS3CRE2
CSC: G950UOYS3CRE2
Download here: G950USQS3CRE2
DOWNLOAD for ODIN:
ODIN v3.13.1
Hello, I have upgraded my ATT S8 to CRE2. Since then, my phone usually becomes overheat and fast battery drainage. Could it be a problem of this ROM version. Should I downgrade to older ROM?
Please help,
Does anybody know if I can just flash the CSC from this firmware to my G950F International phone?
I know you can't flash the full firmware as the G950F has the Exynos processor and the G950U is made for the Snapdragon.
But is it safe to just flash the CSC file only as I want to fully use Samsung Pay?
I'm using the Australia firmware for my G950F and I can't register some credit cards (ie: Discover) into the Samsung Pay app.
