Android 6.0.1 Unknown Firmware

So I've been waiting a while for a firmware suitable for my phone, and not sure if I have. It matches my model (SM-G920F), but the carrier/country just says 'Unknown'.
Is it alright to flash an Unknown firmware onto my phone (Which is Unlocked)

No
but you can use smartswitch to flash it it will choose right ROM for you

Soft bricked my phone trying to flash the firmware around 30 minutes ago :/ (Got it working again though luckily!)
I have tried the smart switch method, but it says my device is unsupported

All you have to do is flash the Stock Firmware onto it. (Usually it completely wipes your phone too, but for some reason it didn't wipe any of my stuff!)

you can flash XEF (France) or any 6.0.1 firmware including Vodafone ones, my G920F is also unlocked and flashed the first one that appeared...no problems

Thanks for the response. Is there a big difference between flashing the french one, than waiting for a United Kingdom one instead? If so what would the differences be between French and UK firmware?

the UK has two preinstalled Vodafone apps that i disabled via the debloater, the french one has no carrier preinstalled apps, i use the Vodafone one and I'm on Orange network and have no problems I'm too lazy to flash the french one, i was eager to get MM on my device and after installing all the apps i thought to keep the Vodafone one because it runs flawless i recommend a factory reset after flashing the firmware

Alright thanks, think I'll go with the French as Vodafone is useless to me anyway!

Flashing stock rom with odin / sw rev. fail

Hi, I recently tried to get my phone unlocked. I watched the guy do it, he flashed an older modem and then flashed a UAE firmware.
My original is O2 UK, and I'd like to revert to this firmware as the About Device section shows up with Unted Arab Emirates and the mobile networks section shows LTE rather than 4G.
I have tried flashing the latest revision of the O2 stock rom and odin fails attempting to write sboot.bin with the error message SW Rev. fail (I don't recall the exact numbers after this) appearing on the phone.
I am guessing this is the secure boot loader, which I am aware you can't downgrade, but is there any way of flashing this stock rom since I know it is compatible with the phone?

Try to flash G920FXXU5DQA7 (CSC code:BTU)

You could possibly use smartswitch if you have the serial number of the phone which would download the default firmware that the phone came with if odin fails again

Yes i agree, smartswitch could be your best option.

Thanks for the suggestions. Tried Smart Switch, same error. It appears on the phone as sw rev. check fail.
What exactly is the problem here? Is it that the installed firmware has a newer bootloader than the most recent O2 firmware? In which case is there any way around it?

Yeah looks like this is a bootloader issue, it won't let you install a firmware which contains an older bootloader, only thing I can is to download the latest non branded UK firmware and see if that flashes.

I'm getting this error too with Device 4 Binary 3 but i didn't find the right firmware yet
I hope in Nougat release

Sammobile is under maintenance right now and there are no mirrors reasonably fast... 8 hours for a download.
Anyway update is coming these weeks, I'll wait

You could try using samfirm which a windows application which downloads samsung firmwares

As @sofir786 said, you can use SamFirm;

Samsung updated their bootloaders to 4XX in September/October so you cant flash back an older one or downgrade,so the only solution you have is to flash the new one which is 5XX released this year.

Flashed the latest UK revision (not the O2 branded one) and it worked

Wrong carrier apps S7 Oreo

Hello peeps, i have installed the latest firmware for the SM-G930F from Belgium (G930FXXS3ERL4_G930FVFG3ERJF_PRO) but somehow the carrier apps from vodafone get installed when booting into the system even though the Proximus app should be installed... I have tried to reinstall it multiple time and still have the same outcome? had this problem with my S6 Edge in the past too but i fixed it somehow (I didn't fix it but it fixed itself tho XD)

There is only one reason this happens, the firmware is not an unbranded international version.
Complete waste of time messing about with Belgian, French,German version etc just Download the BTU firmware from sammobile or direct from Samsung. It's says United Kingdom but it's basically western Europe unbranded.

So if i download and install the BTU version what will be different rom the belgian software? Like i remember with my s4 i used to install BTU firmware all the time because there wasn't one for belgium, but didn't notice anything different with my sim card... so i hope this will be the same that i still have the functionallity like i had before i flashed custom roms

The BTU stock holds all the csc codes, base bands, network functions for all of the European region which means once it connects to the network in your country, it automatically detects which system files to use so you "don't notice anything different" than if you had installed country specific like Belgian.
There is always one stock which hold everything for a region, in Europe its the UK unbranded, generic, international, BTU version. It works everywhere in Europe.

okay so i've installed the btu version and it worked just fine, except it was a little slower and idk why. but when i tried to use mobile networks it wouldn't work so i checked my apn settings and my provider wasn't in there so i had to add it manually wich for me turned into an even slower experience on my phone... I really don't know what i did wrong or what happend, so is it possible to get a detailed instruction to flash the stock oreo rom? and also a how to for rooting stock oreo with magisk? because my guess would be that something went wrong when rooting

Hello well unfortunately Belgium isn't important enough country to have your own unbranded stock firmware.
APN settings should install automatically when you connect to mobile network in your country.
There is a specific guide to follow to root S7 on Oreo, please google and follow it exactly.
Also BTU is a stock Oreo ROM.

Which region for unlocked Canadian phone

Hello all,
My phone is properly stuck in a bootloop and keeps going into download mode, tried for a few hours to get it out but no luck.
I want to flash new firmware, my device is a SM-G930W8 but I don't know the region.. I bought it unlocked from the Samsung Experience Store in Edmonton, Canada when it right came out, but threw the box already.
Which firmware region would I need?
Thanks!

You can download branded to the network your using or unbranded. The firmware that just says "Canada" is unbranded generic.

Samsung Galaxy S7 SM-G930F - Blocked OEM

I was trying to root my phone, did it, but messed something up, so I had to install stock firmware, however, i live in Poland and downloaded stock firmware for Poland, but my phone's country stock firmware was Nordic ( I didn't know that ), since then I can't unlock my OEM because every time I try, it locks again. I don't know why, I have that option but its impossible to unlock because that option reset every time I confirm warning (about knox etc.). I heard it may be because of not same original stock firmware for my phone however for some reason, Polish stock firmware is newer than Nordic, and everytime I try to flash new stock firmware, It shows an error about SV REV. CHECK (BOOTLOADER) DEVICE: 8, BINARY: 7 so it's kinda impossible. Do someone have an idea?
I'm really sorry about my English, I hope you can understand.

A network provider can disable OEM when you install branded firmware. Poland plus network for example.
The Unbranded, generic firmware for Poland is https://www.sammobile.com/samsung/galaxy-s7/firmware/SM-G930F/XEO/download/G930FXXS8ETC3/327938/
It is version 8, downlaod and flash with Odin.

As I said, I already have installed this firmware, and this is a problem, because original firmware for my phone should be Nordic

The G930f can have any EU firmware installed. You said the version you were trying to install is version 7. The firmware I've linked to is version 8 Poland. You don't have to use Nordic as I've said, any unbranded EU countries firmware will work as long as it's version 8, as the error is telling you.
You could install United Kingdom BTU and change language in settings to Polish.
