Help with vodafone branded GS6

Hi the GS6 I bought came with vodafone pre-installed software like vodafone-updates which I can't remove/disable. The rom it has is G920FXXU2COH2. How I can remove software? Should I use another rom and flash it? My phone is G920F

You can uninstall the pre-installed applications, but in order to do that you'll have to root the phone. If you don't want to root, then you can just flash the phone with an unbranded ROM.

Go to app manager and you can disable the voda bloat

The one called vodafone-updates can't be disabled from there.

I find trouble choosing which stock Rom I should install. They are so many. I found out more info that my phone which I bought it from Greece came branded with Vodafone-Germany and the rom G920FXXU2COH2. Some say that G920FXXU2BOFJ is the true G920F international unbranded firmware but somewhere I read it's used in France... Can someone help me here with choosing apropriate unbranded rom?

The country of the ROM doesn't matter, as long as it is for your device model. Just be sure to download an unbranded ROM with the same or newer Android version of the ROM you have installed.

Flashing vodafone firmware on unlocked s8+ purchased from carphone warehouse (uk)

Just a quick q. if and when Vodafone firmware for this device supports wifi calling, will i be able to flash voda firmware.
i ask because i tried to flash voda firmware on my s7 edge via odin and got a bootloop and had to flash BTU firmware in download mode which wiped my phone.
cant be asked to keep resetting my phone all the time

You CAN flash the VOD-firmware, but your CSC will change to the "default"-CSC of the "Multi-CSC OVF" -> VD2
You must use the AP-BL-CP & CSC_OVF of the VOD-package -> it will reset your device (which is necessary)!

Unauthorized changes have been detected. Solution?

Hey guys so after trying the following software (Dr.Fone for Android by Wondershare) to recover some deleted photos off my phone i started getting some message saying: Unauthorized actions have been detected. Restart your phone to undo any unauthorized changes.
Obviously I tried to reboot countless times, tried to do a factory reset and even wipe the Cache Partition without any success. Tried to use Smart Switch too but when going to the Emergency software recovery and Device initialization I get a warning that I need at least 800Mb free. The phone has 16Gb free space . Any solution? Throught about flashing ROM but I don't know if the bootloader is locked by default on Samsung devices and if there's even a official rom.
Thanks in advance

Which model S7?
You can use ODIN 3.12.3 or above to flash a stock ROM from sammobile.com or updato.com
Possible if you check the phone about > status in settings it will say 'Custom', flashing a stock ROM should get you back to 'Official' and remove the error

Regular S7 ( SM-G930F). I'll look into it right now Thanks
Edit : There are so many country ones but there's none for my country. Does it make such a difference? I bought my phone from Germany and use it on a daily basis in Finland. I never heard about a ROM that only works with a specific operator. Besides mine wouldn't even work here.

BTU and XEU are United Kingdom unbranded ROMs, could try one of those
The only things I've heard not working by installing different region ROMs (CSC) is stuff like WiFi Calling / VoLTE etc, haven't heard of anyone not being able to get a signal at all
Check which one you're running now, you're looking at the CSC version
Use this app
https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo&hl=en_GB
Check under "CSC Code" tab to see what you're running, then match it to the ROM you download

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.

OEM unlocking doesn't turn on

When I turn on OEM unlock a popup comes up saying security is disabled and stuff then I press Turn On and it doesn't, it just stays where it is. I have tried flashing different firmware from carrier firmware to unbranded firmware and had no success. Anyone know a solution?

The best unbranded firmware for Europe is the United Kingdom BTU, it enables everything, has all European languages and country codes. Try that.

The thing is when I first got this phone I was able to turn it on no problems on stock Oreo 8.0 then I rooted it and installed twrp then I messed something up with twrp and had to flash the firmware from unbranded DBT again. Now when I try to turn on OEM unlock it just doesnt work as stated in the first post. Also I dont want to through the hassle of downloading another firmware since here it would take ages to download.
