HI all,
i am trying to convert ATT-XAA unlocked CSC to Canadian TLS to get visual voicemail and caller id with name display and Samsung pay...
I used SAMKEY 2 times with CSC TLS and both times it said SUCCESS but after restart nothing has changed. Any help is appreciated.
I tried to flash W version Canadian firmware but it crashed at the end of process....
Am i missing something?
model is sm-g975u1
thank you !
Because it provisions to whatever sim card you have

I have Canadian Telus sim card, trying to get TELUS native apps on the S10plus .
do i need to reflash with W firmware now after samkeys mod?
thanks Butchieboy
Sorry I read that wrong. Not sure about Canadian. But with my US At&t device all I have to do is flash U- firmware instead of U1 which is unlocked firmware. The unlocked firmware is not branded and doesn't have visual voice mail etc. To get that I either flash csc from carrier firmware or flash entire carrier firmware with odin...AP..CP..BL..CSC. Remember flashing csc will wipe device

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.
https://forum.xda-developers.com/s7-edge/how-to/official-stock-firmware-update-odin-t3335065
i used SamFirm_v0.3.6 to download the uk firmware

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
I've been doing fine since I got the Snapdragon S8 Unlocked from USA but recently I saw many places with Samsung Pay and thought it would be convenient to start using it and when I installed the app it defaults to the USA version, although I can still enter my card I am missing out on a lot of Indian Specific features on the SPay. I am guessing this is because the CSC is set to XAA and not any of the Indian ones. Is there any way to change it to Indian CSC codes without rooting?
EDIT: BTW I have tried going into recovery mode, formatting the device, rebooting it with my local SIM installed which did not work, it's still in XAA code. Please don't tell me it's a Snapdragon/Exynos thing which does not allow it to do it. Model G950U1

Other firmwares will work you might just be missing features like WiFi calling. I don't know the exact dialer code but they is a preconfig dialer code to select csc so once you got the latest you could try that. All the firnwares are identical for each us model you wont brick from flashing another carriers
So thats yes right? I can use other carrier rom without any problem?
please some one answer... my device is att s8 smg950u. so can i use smg950u1 firmware to flash 950u?

As long as it's unlocked. A g950 u. U1 and w all can use any csc from carrier firmware. Pop your sim in and flash your carriers csc from firmware
My phone is G950U but it's made in China and works fine with Bulgarian SIM. I have no info about the original carrier. CSC code is TGY, can I flash G950U1 with CSC XAA (Unlocked)?

Yes, the thing is I don't have my carrier CSC available for download since I'm using it in Europe. Wondering if I need to revert flash how to source TGY (Hong Kong) factory rom? Seems all available for download are US-based CSCs only.
My main concern is OTA is currently failing completely, I am hoping to restore by moving away from the TGY code, does that need carrier switching process or just flash 950U1 on top including user data ?

Im pretty sure u1 model pretty much is csc-less i would try to flash the u1 firmware directly and flash the home csc in u1 firmware which should leave it open. BL" "AP" "CP" "CSC" is all you should flash. User data would add a carrier. If you dont it will leave it open.....
If updates are all your lookong for. Just use odin to manually update

I tried 950U XAS and 950U1 downloaded with SamFirm and all versions of Odin but all failed . Strange my S7 from Verizon is able to use OTA in Bulgaria but not this Hong Kong S8.

You are either using the wrong odin or a older firmware.
Or. To flash unlocked firmware you must first flash the combination file then unlocked firmware.
Sorry for a noob question. I haven't been here since my days with an S3.
I pick up an supposedly unlocked G950U on ebay a week or so ago. When I got it It had G950USQU3CRE9 from 6/18 firmware installed. I put in my Mint Mobile SIM and it worked and had no carrier bloatware, but would fail when doing a manual update. Strangely in settings the Service provider SW ver. section was absent. I downloaded at installed via Odin G950USQU5CRL2. Magically the Service provider SW ver is now in settings.
Trying a manual update it downloaded and installed G950USQU5CSA4. SWEET. But I'm confused why I recieved that update.
Under Service provider SW ver it now lists;
SAOMC_SM-950U_OYN_XAS_OO_0075
xxxxxxxxxxxxxxxxxxx
XAS/XAA/VZW
Who am I getting the update for? Sammobile doesn't list SA4 for CSC's XAS (unknown) or XAA (unlocked) but does for VZW
The Phone ID app lists my product code as SM-G950UZVAXAA
Am i getting the update for verizon but a XAA unbloated one? or what? I would think XAS would be my active CSC.
Confused .... My last time playing with phones CSC didn't exist and I can't figure it out.
Also, I would love to flash the G950U1 firmware but there isn't a version a current as SA4, even the pie betas, and concerned about a brick.
Any help in understanding would be GREATLY appreciated.

Xaa is unlocked firmware. I think xas is sprint. But the third vzw means your sales code is verizon so you should be getting updates from them. You can use sammobile or updato get the latest and flash home csc with your sim in and it should go to your carrier. 5th digit from end is bootloader revision thats what you have to pay attn to. As long as you get revision 5 firmware ypur gold. We have locked bootloaders so you cant really brick with odin. You have to flash a rev 5 combination file then the u1 firmware which is the unlocked firms
So what i think is you got a sprint phone with unlocked firmware but with verizon as a sales code for end user if im not mistaken... If thats the case it is most def unlocked sim wise.
I have a couple of noob questions as well Since I'm new to CSC era...
Got s8 950U and was not able to update FW for several months now due to no functioning OTA and Odin failed as I lack the combination file knowledge. My phone appears to be for Hong Kong market with Snapdragon and I use it in Europe.
1) Is it possible to unlock OTA by switching CSC to local provider? Not sure if 950U is even supported in Europe CSCs? What if I pick XAA instead of local one?
2) Any idea how to update to Pie and unlock OTA/Samsung Pay/Secure folder etc.? What is the correct formula to understand which combination file to use before flashing latest Pie 950U1 XAA ROM G950U1UEU5DSC1?
Nobody able to help at least slightly?
i have the same problem with my s8 , thar has csc of hong kong tgy and won't me let download the last updates also i can't open samsung health secure folder s pay ect....any solution ??! ,, thanks in advance
I have the same issue. Phone name is SM-G950U but CSC is TGY (Hongkong). It can not be updated via OTA and I don't know what is its correct CSC.

Will this work for my Rooted Extreme Syndicate s8 g590U nougat? mine says BST/BST/VWZ. (not able to receive SMS texts) Possible to flash DTA6 home CSC without breaking root to update my carrier?
Hello, I have a Samsung S8 that I bought unlocked at Best Buy 2 years ago in USA. It was with android 7.0 at that time.
I can't receive updates automatically now because I flashed it with ODIN last year to get Android 8.0 before the carrier that I use was ready to offer it. So the updates won't be automatic anymore.
So my phone is an unlocked one and I tought that the model # was supposed to be SM-G950U1 when it's factory unlocked but mine is SM-G950U. How can that be possible? I looked at my phone specs and my CSC is still XAA so it's really unlocked. I want to install Andoid Pie manually and I don't know what firmware to use on SAMmobile to flash it to android P because none of the files for the SM-G950U is with CSC XAA. Only SM-G950U1 have XAA firmare available. I don't want to lock my phone to a particular carrier.
Another thing I tried to update my phone: I used a series of firmware updates available at firmware.science. The problem is that the last update I did was from G950USQU4CRE9 to G950USQU5CRG1. If I want to continue the chain of updates, the next available step is from G950USQU5CRG3 so I'm blocked because I'm at G950USQU5CRG1. What can I do to go further in my update process?
Ultimately I want to be able to automatically update my phone to android Pie.
Thanks!

You can use SamFirm, SamMobile or Updato to download SM-G950U firmware G950USQU5DSC1. (Don't download G950USQS5CSB1 which is for Sprint or Verizon.) That firmware file includes all CSCs for US carriers and the one that gets used depends on the sales code in your phone, which is XAA in this case. Flash that firmware in Odin and you should be fine.
Oh, and I am 100% sure that the G950U firmware includes the XAA CSC... It's installed on my phone right now!

I looked on updato and the link for the update doesn't work. On SAMmobile I see 7 different countries/carriers for the file G950USQU5DSC1 for the SM-G950U. Which one should I get? None of the is XAA.

Hello, all I did was to choose the right firmware on SAMmobile (https://www.sammobile.com/firmwares/galaxy-s8/SM-G950U/TMB/download/G950USQU5DSC1/264390/), download it and follow each step to update with ODIN like you can see by searching on Google "How to Install Samsung Galaxy S8/S8+ Android Pie (One UI) Update".
I'm not in US even if I bought my phone in the US and it works in Canada with any carrier with the firmware from T-mobile. That is all I can tell you about how to choose the right firmware.
