Please help change firmware - UK vodafone - Galaxy S6 Q&A, Help & Troubleshooting

Please help, I have searched the forum but dont seem to get a solution that works!
I bought an unlocked S6 Duos some years ago and now need to put the official UK vodafone firmware onto it so I can use wifi calling
I have downloaded the firmware and tried to flash with ODIN but always get it failed when doing the image file. I have also tried to change the CSC code using the dialer but get MMI errors (even though it is connected to the network and I can make / receive calls).
I am sure I am doing something obviously wrong but cant figure it out! Any help really appreciated!
here are the details I have from my phone
Model SM-G920f
Active CSC code SIM
Available CSC codes.... lots including VOD (which is the one I think i need)
Bootloader version G920FXXU3DPBG
CSC Version G920FVFG3DPC1
Baseband version G920FXXU3DPB6
I have been trying to load :
Bootloader G920FXXS3DPF5
CSC G920FVFG3DPC1
Many thanks,
CHris

Did you manage to get this to work. I am considering doing the same..does it still remain as a dual sim phone after ?

Failing to flash stock firmware.

As title says I am having trouble flashing original stock firmware onto my phone.
The model number is: SM-G920F.
I originally installed a rom which caused my phone to lose it's baseband. I then tried to flash a stock firmware and it didn't work. In ODIN it just fails instantly.
I noticed that in download mode it says that the "product name is: SM-G920P" however.
So I flashed the G920P instead which got it working back to normal.
The only problem is I don't live in the US. I live the UK. The firmware is rejecting my sim card.
I want to flash the G920F and am having some trouble. If anyone could help I would appreciate it if someone could talk me through this.
I have looked around the forums etc and I haven't seen a solution to my problem.
Thanks in advance.
You've got a CDMA version of the S6, as far as I know, no UK carrier uses CDMA, they use GSM, so you're out of luck if you want to get it to work in the UK.

You can try using "Smart Switch". I wasn't able to flash ITV firmware over the BTU, it failed at hidden. I tryed with Smar Switch and it work.

S7 HELP! Phone changed imei, changed the model and cant connect to the network.

Good morning XDA,
I'm in desperate needing help, sorry but English is not my first language.
My brother bought a S7 G930F - Exynos that was GSM locked with one company here in Brazil, so he paid a guy to unlock it.
After getting the phone back I notice that the phone now shows G930FD, when I use *#06# to see the IMEI, shows two number, as if it was Dual SIM and both numbers are different that what is written in the back of the phone and the box and the rom seem to be 6.01 but with a lot of programs pre-installed.
So I downloaded the newest ZTO stock rom from SamMobile and flashed, now the phone is on 7.0 but can't connect to the network and still show the tow differents imei numbers.
Any tips or guidance and how can I Solve this?
Thanks, TggB!

Samsung S8+ CSC change on Exynos F model

Hello,
I have been trying to find an answer to my question or a solution but all the results I found on XDA are Snapdragon model oriented.
My question is about changing the CSC just to be able to receive OTA updates faster ( I don't want Samsung Pay ..) . I aleady know that the product code is hardcoded into the phone I just need to change last three letters of the CSC.
My rom is part of the OXM multi-CSC rom, I flashed it and tried the famous code to change the CSC region but no results so far. I also do not have any other sim card to trick the phone after factory reset.
Could anyone please help ? has anyone been able to change CSC via odin ?
Regards.
Can anyone help please ? is my question a little bit confusing ?

Changing CSCs isn't possible without root or without a local SIM card from the country whose CSC you want to use.
If you're so eager to get faster updates, just flash them with HOME_CSC_OXM as they are released, you won't lose your data and you'll be on the latest OXM builds as well.

At&t branded phones on Tmobile network

My wife works in a hospital and we used wifi calling because reception was poor.
It's still poor with Tmobile but no wifi calling. When we moved from At&t the wifi
option was greyed out. Tmobile states that it works fine on their network.
Is there any way to get a samsung s7 g930a and a samsung j7-j727a to use wifi calling
on the Tmobile network?
I'm sure it will probably involve something over my pay grade but I am willing to try
anything needed to get this feature to work

If your current firmware has WiFi calling (Volte) You can only use Volte if the network supports it. There are however many apps you can use for WiFi calling look on the play store.
Not sure what volte is, I have had some other issues with the
service that I thought might be resolved by installing a
different rom
Tell me if i'm wrong
Thanks

Volte is wi fi calling over a network which the network operator supports without the need for a specific app.
Please tell me exactly what you are trying to do
What network are both phones using?
Which networks were the phones on initially?
Have you modified the phones in any way? Root? or TWRP?
What firmware are both phones currently using? Go to Settings>about phone>software information>baseband version G930A????
Sorry for not getting back sooner
Both phones are currently on Tmobile network
Both phones were originally on At&t network
No modification
Samsung s7 g930a baseband version G930AUCS8CRL1
Samsung j7-j727a baseband version J727AUCS4BRL1
Note: Wifi calling was available on original at&t network but is now greyed out on tmobile network

Ok since wi fi calling is network specific (some have it some don't) you either need to have unbranded firmware on your phone so it works no matter which network is providing it, or you need to now flash T Mobile firmware for it to work again on your phone.
US networks are a nightmare when it comes to this sort of thing and it's a right pain in the a** to solve it. So what you need to search for now on here is how to flash different firmware on AT&T S7. You should always try to flash unbranded firmware so everything works easily, if not it will have to be T Mobile Oreo.

Ok, If you think unbranded is the best way to go can you point me in the right direction
updato.com and sammobile.com both host firmware and have flash guides. SamFirmTool also is good for downloading firmware, but only lets you download the latest version and isn't as user friendly.
For unbranded you'll want to look for G930U firmware.
For best compatibility you flash all 4 files using (AP,BL,CP,CSC) this will wipe the phone clean. Otherwise you can try Home_CSC instead of CSC (So AP, BL, CP, Home_CSC) , which keeps your data but may not fully resolve your issues.

What beanvee has said but I think it's worth mentioning I find Sam Firm tool pretty straight forward to use and you'll always get the firmware in separate parts which can be useful.
I found a link for the G930A here
I'm not really understanding the differences in firmware. How is flashing with this firmware
any different than what's on the phone right now?
I am just trying to get the wifi calling to work, How is flashing it with at&t version firmware going
to help me on the tmobile network.
I guess I don't know what I need, stock, unbranded, official or custom rom.
I checked all sites listed and there is no firmware for the J727a, alternative?
I would rather someone more knowledgeable guess what I need to do, if that is what is
necessary because the phones are no good to me without that feature. Any suggestions
would be appreciated.
Each carrier deploys their own CSC file, which contains carrier specific configurations, and its this file that determines if VoLTE or VoWIFI is enabled and how it connects.
AT&T may have different VoWIFI settings to TMobile, which is why using AT&T firmware it doesn't work. Some carriers outright disable it since they don't offer it.
Your best bet would be G930T firmware https://updato.com/firmware-archive-select-model?q=SM-G930T&rpp=15&order=date&dir=desc&exact=1
However unbranded G930U should also work because the unbranded firmware is meant to work on all cariers. G930A would likely get you no where since it'll be AT&T specific
The phones in the USA are all identical hardware under the hood, the only difference is the carrier branding and firmware.
But that's only for the S7, I'm not familiar with the J7.
And it's not through lack of knowledge @JohnAtlas, US phones are a nightmare to do anything with. There are several options available but it's difficult to explain what to do and how to do if you are not familiar with how the software works.
There are many guides on how to unlock the software on all US networks, and depending on the network can include multiple steps to complete, you just have to search and read.
Ok, I was able to find the latest firmware for the G930 phone
I installed odin and have the files, BL, AP, CP, and CSC or Home CSC
My question is, Do I load all files and then start or do one file at a time in odin
I tried all files the first time and got failed error and dismatch
Thanks

All files in correct slots and use this Odin https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
Put all files in and used patched odin via link
Received fail and screen that said, "An error has occurred while updating the device software"
After reading more, tried to install twrp and received secure check fail : recovery
Rebooted phone and this is the screen right now, not sure what to do next

That is the system recovery and when you flash with Odin you need to put your phone in download mode first press volume down+home+power. The phone should not go to that screen you have posted either before or after Odin, its a completely different recovery mode.
Get your firmware from updato. Com or sammobile
G930U, filter by USA and choose the latest XAA or USC and use the modified version of Odin. We know this works because thousands of people have used it to do what you are trying to do.
Thanks for info, I used G930U TMK version since we are on Tmobile carrier
It seems to be working fine and wifi calling is available
There is no TMK version for the J727U but will try the XAA for the other phone
The way I understand it is that the U means unlocked and the XAA is generic and not carrier specific
Please advise if I'm not on the right track
Thanks for your help

That's brilliant , glad your up and running.
So the letter "U"after the "G930" denotes the region of the world the device is build to operate in, the Americas just happens to be U. The unbranded firmware is the one that has a region but no network assigned to it, so a 3 letter code is used instead, in your case its USC, or XAA.
Europe is G930"F" or "FD" and the 3 letter code for unbranded is BTU & XEA.
Anyway if your phone is running great on T Mobile then don't update it anymore, turn auto update off. The advantage of keeping it T Mobile is you have the wifi calling, the unbranded firmware needs more fiddling around with the get the wifi calling working on the network your using, so best to stick with what works.
I will have a look for firmware for the J7 you have to see if i can recommend doing something with it to get the wifi calling working.
*update*
So it seems the J727 is the same as the J7 in terms of the internal components, everything is the same in both models so that's great news. I think the "27" bit is just a marketing thing.
In theory you should be able to flash the latest T Mobile Oreo to your device from this link https://www.sammobile.com/firmwares/galaxy-j7-pop/SM-J727T/TMB/download/J727TUVS4BRK1/249137/
Now before we start please check / do the following to avoid further problems.
1. Save everything you need from the phone to your pc.
2. Check that you have OEM unlocked in "developer settings" and "USB debug" enabled.
3. developer setting menu is, settings>about phone>software and information>build number>tap 7 or 8 times, developer menu should now appear. (Sometimes it's somewhere else but build number is what you want to find and tap on 7-8 times).
4. To avoid any issues with device FRP lock, delete your google account off the phone., settings>accounts>google. delete it. When successfully flashed you just add the account again when the phone starts for the first time by signing in.
5. Use the same version of Odin you used to flash your S7.
you can also use updato.com (i think it's slightly faster than sammobile.)
Let me know how you get on.
Remember J727T (TMB) is the firmware you want.

Finding the correct firmware to fix soft-bricked phone.

Hello,
I'm trying to fix my soft bricked phone with this error (no quotes):
"dm-verity verifiation failed..."
I've already soft and factory reset the phone to no avail, as it still will not boot past the Samsung logo. Googling the problem has told me that flashing the original firmware with Odin should fix it, but after hours of searching I still cannot determine what firmware I need to download and use. Reading some of the threads here supposedly i can use firmware that shares my carrier and country but I cannot find the correct combination on any site.
Country: US
Phone: S7 (G930F) - On the recovery mode screen the full designation is G930FXXU1BPH6
Carrier: T-Mobile
Version 6.0.1
Does anyone know exactly where I can find useable firmware for the phone? Everything I see online (like sammobile for example) just has the firmwares for other countries.
Before the bootlock my phone was rooted if it matters.

The G930F is a primarily European device, so a different region than the US.
The firmware version you have provided is an old version of Marshmallow on T Mobile Poland. The fact that it's Poland doesn't really matter it's still EU region.
Now heres the important part....T Mobile in Europe do not use all of the same bands as T Mobile US so although you can flash any firmware for Europe your phone will not work 100% in the US
So first of all flash with either a nougat firmware for United Kingdom T Mobile or Untied Kingdom nougat undranded (BTU). From Sammobile.
I don't advise going straight to Oreo because there may be a fix for older nougat firmware from EU region to work perfectly in US. Once you upgrade firmware you cannot downgrade.
Once your phone is up and running you just need to look on the forum of how to get a G930F device working perfect on US networks.
