I am on Telus and bought a USA phone. I have flashed the updates using Odin and the HOME_CSC so that it could be carrier set to Telus.
However, it still does not get wifi calling and volte even though I've had the carrier enable it too. The CSC did enable HD voice though.
My question is whether I can flash the offical Telus firmware on my phone as the hardware looks to be the same.
I believe I will need the modded Odin but just wondering if anyone has had success with other models rom on their phones.
Hi Everyone,
Can anyone point me to a download link for the stock AT&T Oreo firmware for the s7 edge. I found a few but the AP file is coming up as a zip. Even after I rename it to follow the meta.md5 filename odin gives an error which states something about binary mismatch. I dont really want to go back to the unlocked firmware because I will loose the stock ATT& features.
Thanks for the help!

It's not just a name it's an extension you can't just rename it.
Use the samfirm app from xda for a better download rate.
Put it on automatic and decrypt download.
Model SM-G935U
ATT as region code for att firmware.
When you click check update it should say this
G935UUES4CRG3
That is that latest firmware for att.
Hi,
I did change the file extension as well not just a simple rename. Ok I will give that a try. I thought samfirm was discontinued? Also if i download the SM-G935U that is just going to be the unlocked firmware isnt it? Sorry still new at this.
depends though, if your model number on the back of your phone is sm-g935a or sm-g935u
att has 2 different phones
both have att branding and wifi calling volte and apps
as long as the firmware you install has the csc ATT then it should be fine.
if you have the 935a then you can download at the att sections of the forum.
Samfirm may be an old tool but it still works as intended
if u have the 935a just change it to SM-G935A in the samfirm app.

Can't I just install a g935u firmware on a g935a phone?
I just don't want to keep AT&T apps.
As the title says, I download G950U1 firmware from update.com for XAA/XAC carrier (unlocked carrier). But then I noticed some sprint related system hidden apps in apps settings. So, I decided to download T-Mobile G950U1 firmware. But I was surprised to know both download files were same. I thought it might be the name which is same, So, in order to verify I checked the MD5 of both files and they were same as well.
Here are the links for both firmwares.
T-Mobile
https://updato.com/firmware-archive-select-model?record=461107208CD211E89F15FA163EE8F90B
XAA
https://updato.com/firmware-archive-select-model?record=581DBD798CD211E89F15FA163EE8F90B
As you can see links for download page are different but if you keep cursor on download button for a few seconds and then copy actuall download links then they are same on both pages (Not sure if this is case with all G950U1 firmwares)
T-Mobile

Does anyone know why is so? And I wanted to cross flash from G950w to G950U1 to get rid of carrier bloat and useless apps permanently, that's why I downloaded these firmware. Currently I'm running that mentioned firmware.
This won't help your issue at all but I have an unlocked S8 with the unlocked firmware on ATT and can't get VoLTE, WI-FI Calling, etc. so check to make sure you can get those on unlocked firmware on your carriers network if they're important to you.
Hello, i am using ATT Galaxy S8 SM-G950U Unlocked Phone. When i am going to search any new update or firmware for my phone, i rarely find them even in sammobile I find most T mobile, verizon, sprint updates or firmware than ATT. So can i use other carrier rom for my device Or i have to stick with this ATT? Currently im using may 2018 firmware for my device. I searched a lot for newer firmware but couldnt get any. And can u tell me when the pie update will come for this device.
Also can i install pie beta on my phone? Bcoz its tells that it will work on snapdragon but doesnt tell att or t mobile or verizon...

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.
I have a Verizon SM-G975U with the firmware G975USQS2ASGB, Now i just switched over to T-Mobile and would like the T-Mobile firmware on my device since while I get service, it is not as good as my family members galaxy s10+ from T-Mobile and putting the T-Mobile sim card in when I switched didn't updated my firmware. How do I go about doing this since I am new to firmware flashing. Is sammobile.com a legit site? do I download the firmware there and follow their instructions? I would love it if someone would give me dumbed down instructions on how to do this without bricking my device and preferably not having to do any factory resets but if I have to I will and just restore my smart switch backup, thanks for any help.
There is another thread with flashing instructions. You need to use the modded Odin, not the official version.
I think if you are already on carrier firmware and want to switch your phone to a different carrier firmware you need to flash U1 firmware and convert your phone to carrier free/unlocked before you can convert to the U firmware from a different carrier.
Sammobile is a legit site but there are no guarantees you won't brick your phone when flashing firmware using unnoficial software like the modded Odin.
But the chance of bricking is small as long as you don't flash incompatible firmware. Flashing T-Mobile firmware (with the T-Mobile User Data file) over firmware that is branded for a different carrier will probably brick your phone which is why you need to flash U1 firmware before switching to a different carrier firmware.
