Hi
I have a Three UK branded Note 4 and I'm currently using it on Vodafone. I'm looking at flashing the stock firmware for the UK to debrand the device. Does this process change the radios at all?
The reason I ask is because sometimes I'm seeing loss of mobile data that I can only resolve by toggling flight mode. I'm wondering by flashing stock or indeed Vodafone firmware would help this situation.
Thanks
If it's a newer firmware than the one currently on your device, then it will more than likely contain a newer modem firmware too.
Post back how you get on.
I have a Three Note (although also using Three network) was thinking of rooting/flashing to get rid of some Samsung bloat.
flashed my vodafone handset to BTU stock no problems and yes it does debrand the handset in the process. As for radio's just let it update if needs be better to have the correct radio for the rom version.
Did you find any benefits over the Vodafone branded version? Improved battery life for example?
I recently purchased a Galaxy S4 i9505 on EE from Carphone Warehouse, and flashed the 5.0.1 BTU firmware. After I did that I then read I'd need to be carrier unlocked, but I tried calling and receiving calls and messages and using 4g and it worked fine. I also saw some posts about flashing modems. Anyway I'm really confused about what I need to do; should I try and unlock or not. Thanks everyone for your help.
The BTU firmware has no carrier branding, which means it has no carrier logos or bloatware included in it. Other than the lack of carrier doodads, it's the same firmware. You shouldn't need to flash a modem as you already have the latest, from when you installed the BTU ROM. However, the S4 would need to be unlocked for use on any carrier if your SIM isn't an EE SIM. But, you either have an EE SIM, in which case you don't need to worry about it, or the S4 was unlocked by the store that sold it, in which case you don't need to worry about it.
TL;DR: Don't touch the ROM. Don't worry too much about the SIM because you can make calls and use data. You don't need to flash a modem.
OK, I flashed my G935FD dual sim with G935FXXU1BPH6_G935FVFG1BPH1_VOD ( I did AP BL CP CSC), it rebooted did a couple of OTA updates, has wifi calling enable, but still wont wifi call, or go into wifi calling mode.
After the flash and OTA's I checked the versions and have :
AP G935FXXS1BPJ1
CP G935FXXU1BPHJ
CSC G935FVFG1BPH1
this is exactly the same as my UK Vod shop purchased G935 single sim, which obviously does go into wifi calling mode
One minor point, my G935FD dual sim phone receives messages dfrom VOD after a sim change stating auto configuration of APN is not possible, is VOD UK still detecting my dual sim device and disabling wifi calling
any ideas anyone pls, has anyone got WiFi Calling to work on 935FD for Vodafone?
cheers
(oh, also tried G935FXXS1BPJ1_G935FDBT1BPH2_DBT.zip and didnt even have the wifi calling check box )
I have mine working on the att version

cool, I have heard from other ATT or UK EE users who have made this work easily, just no vodafone users
update here from me :
Having tried many roms, with no success, I reverted back to a UK VOD ROM, as this was a multi CSC ROM, which defaulted to VOD2 CSC (Germany I think), I rooted the device and changed the CSC to VFG (VOD UK I believe)
Still no wifi calling, though it is enabled in the CSC and onmy account I dont have the check box under phone settings -and have no idea how to force it to appear.
Any ideas pls, has anyone successfully got WiFi Calling to work for Vodafone (UK ??) on a 935FD ?

I am interested in getting a dual sim version of the s7 edge to use with EE in the UK. Could you please elaborate on compatibility with EE's wifi calling? Did you read about it in some forum? Do you know people who have tried it? Do you know exactly which versions are compatible (935FD, 930 , etc)? Thanks!

So you flashed a single-sim firmware (for G935F) onto a dual sim phone (G935FD) and it worked? Did you retain dual sim functionality?

Yes flashing firmware for the G935F retains Dual SIM functionality, mine is flashed with the BTU firmware as UK s7 version
@copex , thanks! Are you on EE? Have you had a chance to verify if wifi calling works?
Also, is there any particular way to flash the firmware with Odin? Or shall I just follow one of the many guides on the web?
I don't need to be rooted, right? I don't want to root because otherwise I won't have access to my work email.

I am on EE but via Plusnet mobile and they do not support wifi calling, i used Odin to flash the device as i changed the CSC to BTU i done a full wipe so i could get OTA updates, i followed the info here.

What do you mean exactly when you say you changed the CSC? When you ran Odin, did you load all 4 files: BL, AP, CP, CSC ? Specifically, did you load the CSC file or the Home_CSC file in the CSC box?
Thanks a lot!
On a different note, where were you able to buy a dual sim s8?... all the ones on Amazon come with a clear "no Warranty" disclaimer.
I am not sure dual sim S8s are out yet - we were talking about the s7 edge. These dual sim phones can typically be bought in countries like the United Arab Emirates or Hong Kong, or on ebay, but if you buy from there and bring the phone to Europe or the US it basically means no warranty. There are also lots of small websites that sell them, but I wouldn't even consider them unless they support the paypal guarantee - who are you going to sue if they don't send you your phone?

when you download the BTU firmware there are two CSC files one will allow the phone to update and keep the data and the other will wipe the phone and you will lose all of your data, when you change the CSC region you have to do a full wipe to get OTA updates, if you upgrade the OTA updates will stop if the CSC region is changed
you have to flash all 4 files.
the csc file i flashed was CSC_BTU_G935FBTU..................................... if i remember correctly the CSC_HOME............... is the one that updates the phone
HI
I have a dual Sim S8 g950FD, i bought it from Singapore airport.
I want to use the wifi calling option but it is not available under any of the conditions that i have used
I have attempted unsuccessfully to flash a stock rom which i assume would have got rid of any of the carrier restrictions that they have on the handset. it failed as the stock rom was older than the installed software.
All i want to do is use the Wifi calling function
Any ideas or links would be most helpful
thanks in avdvance
Noob here. Checked forums for answers, but getting confused.
Just bought an S8, model SM-G950FD, which appears as though it's from UAE. I'd like to avail myself of VoLTE and WiFi calling on my main SIM (these features aren't important to me on my secondary SIM). CSC on phone is OXM_XSG.
1. Is it possible to flash my phone with a Canadian CSC even though my processor is Exynos?
2. If yes, where do I get the appropriate file to flash?
3. Can somebody spoon-feed this old guy on how to do this? I already downloaded Odin, but I want to hear from some more experienced folks so that I don't brick my phone.
4. Lastly, my main SIM is Canadian but my second SIM is from Europe. If I change my CSC to a Canadian carrier, will this affect the operation of my European SIM?
Thanks for sharing your experience.
