Hi Guys,
I purchased a Note 8 (950F) through Gumtree and although I knew it had the Telstra firmware,
I figured I'll just flash the regular Australian XSA unbranded firmware via Odin
and get rid of the Telstra branding as I have done in the past with other Samsungs.
Currently I use an Optus sim (which works) but have lost VoLTE and WiFi calling.
I have tried searching through these forums for a solution but can't get a clear answer.
When I flash the unbranded XSA firmware (BL, AP, CP and CSC, NOT Home_CSC)
I still get the Telstra branding and the software info remains on TEL/TEL/TEL.
Is this normal now? Are we forced to buy a phone from a network carrier if we want to use their services?
Or is there a way to make the switch but I am just overlooking something.
I don't want to root the phone or install anything custom as this will break some banking apps that I'm using.
Please help...
Currently I'm on XEF/XEF/VAU because just upgraded to Oreo, the original CSC is VAU/VAU/VAU
0. Backup your data
1. Download New Zealand or other country firmware.
2. Take both SIM and SD card out.
3. Flash the firmware of other country using CSC, not home_csc
4. Then check your CSC, should be changed.
I did't test the following steps, but I will try this weekend.
5. Flash back to Australia firmware.
6. Check the CSC number, should be changed to XSA
7. Insert SIM card.

Thanks for your input, I was considering this as I want Oreo as well but not game enough to try and mix other countries CSC's yet.
I read somewhere that Oreo will be widely available for most countries as of 1st of April, so I might wait till then and try again.
This does NOT necessarily mean Oz...
Remember, we are at the end of the list to get it as our stupid legal system upheld some patents on icons that Apple took out...
Also, if you're with any of the Telco's, add at least 6 months to that date...
Did you ever manage to get this sorted out? I'm in a similar boat to you, I have an Optus device but a Telstra Sim, when using the Telstra sim, I have no option for VoLTE, but when I use my Optus sim I do. Would like to get VoLTE and other features working on my Telstra sim.
For those who aren't already aware, G998U is the model number of all of the US carrier versions of the S21 Ultra. The G998U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. A "U to U" or "U1 to U1" flash does not require a factory reset, but changing from one firmware to the other will require one. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.
Manual Odin flashing is designed for those who:
- want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
- want to flash U1 firmware to their U device
- want to convert from U1 firmware to carrier U firmware
- want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)
For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via the various firmware download tools posted here on XDA like SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I pay for a subscription to a site that gets the official releases (usually) before they hit the firmware download tools, so that's where my files come from.
This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware (or haven't done it in a long time), I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.
Happy flashing!

Notes:
- DON'T QUOTE THE OP WHEN YOU REPLY, kthx
- I have lots of threads just like this one for other Samsung flagships, if it interests you. For those who have already made use of my previous threads for a different device and are upgrading to an S21, welcome back
- My zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- it's quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single Sx and Note x model, so I won't be uploading every single version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit the firmware download tools.
- My naming method for folders on AFH is: build - bootloader - Android version
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.
- HOME CSC file keeps data intact; using the other CSC will wipe data. Flashing USERDATA will also wipe data.
- Since AT&T doesn't allow their firmware to be publicly available (for any of their devices), I'll try to always upload at least one USERDATA per bootloader increment for AT&T (and Cricket, if they get this model). I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.
- For identifying USERDATAS, and to know what region/CSC to use in the firmware download tools if you're downloading yourself:
AIO = Cricket (not available via firmware download tools)
ATT = AT&T (not available via firmware download tools)
BST = Boost Mobile
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
DSH = Dish Network
SPR = Sprint
TMB = T-Mobile
TMK = Metro PCS
USC = US Cellular
VZW = Verizon (available via firmware download tools, but Manual Entry is required - Auto will not work)
XAA = U1 firmware
- the correct procedure for switching from one carrier's firmware to another carrier's firmware is:
1. Flash full U1 firmware package including non HOME CSC
2. Upon boot, insert a SIM of the carrier whose firmware you want
3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it
4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want
Flashing the U1 right away when my Devices arrives

That's why I post it
That, and so that anyone interested can dig through the firmware for anything interesting.
I'm uploading in order of model number, so Ultra is last unfortunately - and my upload speed is only 10 Mbps. Should be up in the next few hours though
Initial U firmware and AT&T USERDATA are posted, along with U1 firmware. U firmware is not yet accessible in the firmware download tools like SamFirm and Frija, but if anyone wants a different carrier's USERDATA (for flashing bloatware to a U1 device or for converting a U device from one carrier's bloatware to a different one), let me know and I'll get it for you
Are anyone know if Is the version SM-998U or SM-998U1 have or not dual SIM?
Thanks for doing this ! My phone arrives Wed and of course I wanna flash the U Home CSC to my unlocked U1 device so I can get the AT&T calling features. Are the ones you've uploaded the latest firmwares?
And thanks again for always taking time to do this!!!
Sorry for the possible silly question, but I am coming back to the Galaxy after 4 years on the Pixel and haven't been flashing for a while.
I am getting an Ultra from T-Mobile. If I flash the U1 (to remove the bloat) and then follow the instructions above, it says it will put the carrier files on there. Will that just put the bloat back on? I guess I was wondering if it would make it "stock" going forward. I just wanted to figure that out before I set the phone up since it requires a factory reset. Thanks!

No, that's not what it says - I think you're mis-reading. Flashing U1 removes bloat, period. If you want the bloat gone, you have no need to do anything else other than simply flashing U1 firmware

Oh perfect. I checked again after your post and my confusion was at
"the correct procedure for switching from one carrier's firmware to another is". I was thinking it was the procedure to switch from a carrier firmware to any other firmware including U1. So the re-adding of the carrier files didn't make sense.
Thank you very much for your quick answer!

Go create your own thread if you're going to post links other than the ones in my OP
I do have my own thread about these firmwares, I was just including the Canadian bloat free firmware because you only have the US firmwares. The links are to samfw because they update them regularly so people can get the latest releases where as your links are the current version you linked so if you don't update them then they'll be out of date versions. Do you get paid from your Android File Host links or something? What's the issue? No need to be hostile, just trying to help provide information
EDIT:
Also, when you're flashing between different carrier firmware's, you should only use CSC and not HOME_CSC because keeping the user data sometimes includes the bloat apps preinstalled.
The rule of thumb is if you're CHANGING anything, start fresh with CSC
If you're UPDATING from the same carrier firmware to a newer version, use HOME_CSC.
So for anyone using this guide, it's not recommended to use HOME_CSC when converting over to the bloat free firmware as it's a different carrier release. Not saying it won't work, it's just not recommended, almost like a dirty flash so it could cause stability issues down the road after a few OTA's or something.

XAC is for model G998W. The title of this thread makes it clear that this is only for models G998U and G998U1. So kindly delete your posts, and keep them in your own thread
Okay, post deleted, but it's probably worth noting that you don't know what the G998W is. Because it's the same phone as the U and U1. During the One UI 3.0 Beta on the S20 Ultra, I flashed G988U on my G988W, and when the beta continued onto the U1, I flashed those firmware files as well. The Canadian S20/S21 is just a non branded T-Mobile with more supported radio bands in the firmware.
If you actually look at the carrier info for the S20 Unlocked U/U1/W firmware, they all say XAC and XAA at the bottom no matter whether it's U/U1/W. They are all the same phone and Samsung even uses the same firmware merged, just different radio bands, and because Canadian radio bands support ALL bands, it makes the W firmware the a merge of both U and U1, so it's actually the better choice from what you have posted because it supports every U/U1/W the best. So your post is relevant to the W models whether you want to accept it or not.
That's why I included a link to the firmware, because it's the same device, same flashing process, completely same procedure, so this thread IS relevant to the W models even if you said U and U1 only, the W is also included in that even if you didn't say it was, doesn't make it true.
Also the only difference between U and U1 is U is unlocked but INCLUDES carrier bloat, U1 is unlocked and has NO carrier bloat.
So, closing info here.
U1 is unlocked, no carrier bloat, US radio bands
U is unlocked, HAS carrier bloat, US radio bands
W is unlocked, no carrier bloat, ALL radio bands
You just need to make sure it's the SM-G998W for AXC and it's the best choice with no bloat.
Just because you clearly didn't know this about the W phones, doesn't mean you gotta get all snappy, I'm just trying to help the community.

I'm absolutely very well aware of what W models are. Thanks.
Then why are you mad I included it when it's the same device? I don't get why you're being salty about it. I'm just trying to help out.

1. Not mad at all
2. It's the same device internally, yes. But this thread is about software - not hardware. And the software being discussed is the USA firmware, not the Canadian firmware.
sorry I've also been out of the firmware game for a while too. I have a U1 from Samsung unlocked S21 Ultra and need to put the ATT carrier firmware on it. If I'm reading this right, I'm using Odin and flashing the XAA U1 firmware without a sim, when it reboots and reads updated SIM carrier setting at reboot then I am shutting it down and immediately attempting to install the ATT U1 firmware (all BL, AP, CP, CSC (non HOME CSC)? I don't see where I would select USERDATA but I need the ATT options (was going to exchange it but I got all the incentives)

1. If your phone is already running U1 firmware, there's no need to flash it again
2. If you don't see the USERDATA slot, you have a very old version of Odin
It is running U1 but I need the ATT bloatware.....I'm on FirstNet and the only way it will connect correctly is if it's running the ATT built in config files. So I'm trying to go from clean to dirty!!
I have Note 9 with Indonesian Firmware and im thinking to flash Australian firmware. I checked the phone model number and its exactly same (N960F/DS). what im worried about is
1. if I flash Australian firmware, would I keep getting the notification if theres any patch / software update or I'll have to find the update manually?
2. if I still get the patch / software update notification, would I get the Australian ver. or the original (Indonesian) ver? (im afraid if its different)
3. Would Samsung Pay System work in Australian firmware? ( I read if you flash different firmware to the phone model, some functions wont work including Samsung Pay System).
Any help would greatly appreciated
1. if I flash Australian firmware, would I keep getting the notification if theres any patch / software update or I'll have to find the update manually?
if you flash the firmware with the Austrailian CSC, you will only get updates from carriers within that CSC in accordance with what network your SIM is connecting to. Only time you flash them manually is if you have an aftermarket recovery such as TWRP
2. if I still get the patch / software update notification, would I get the Australian ver. or the original (Indonesian) ver? (im afraid if its different)
see above
3. Would Samsung Pay System work in Australian firmware? ( I read if you flash different firmware to the phone model, some functions wont work including Samsung Pay System).
samsung pay doesnt work in certain countries period. that might be what youve been seeing

I tried to flash with Global Australian CSC (not for any specific carrier) and I was be able to get update OTA. Now, the problem is after I flashed Au firmware (incl, BL, AP, CP, CSC) with Odin3B, somehow the service provider software has changed to AUT/AUT/XID while previously XID/XID/XID which is weird. I tried flash using HOME CSC file and couple times I re-download the firmware and flashed other unlocked au firmwares (with android 10 version) it still gave me AUT (Switzerland) instead of XSA (Australia).
Any idea why?
I have a U.S. Unlocked (snapdragon) S21 Ultra that I'm currently using on AT&T (SM-G998U1). Using the dialer method, I obtained my CSC of OYM. Frija will not recognize OYM which I guess means multiple CSCs are supported? I don't want to install carrier-branded software. I tried the CSC code of USC and Frija accepted it. Is this the right code to use? I don't want to install the wrong firmware and brick my phone. Any guidance will be appreciated

So if you don't want to install AT&T Firmware then the best option is to stick with the USC Firmware which is the software on your device. What's the motivation to replace your firmware with the same firmware already on your device? Your Primary CSC can't be changed, it will always be USC. Changing firmware with a different CSC typically causes more problems than it solves. OYM means it's a Multi-CSC phone, USC is your actual Primary CSC. Whatever service provider's SIM you use will be the Active CSC. One drawback in Unlocked Samsung phones is they are the last variant to receive OTA Updates.

The motivation is I'm tired of waiting a month after release of updates to get it on my device. This particular update is supposed to offer camera improvements of which I'm anxious to see. No, I don't want to change CSC or carrier software. I just wanted to make sure I was using the correct code for my device. I'll give it a try shortly and thanks for your help.

I got it updated. The zip file app I was using (IZArc) kept returning an error on the AP file. I switched to 7-zip and problem solved. I got a pass from Odin and phone rebooted into the OS so all is good. It should go fast and easy next time. Thanks again varcor for your help.
That's great, next time you're looking to see if there's an update try Smartswitch. Much easier than flashing firmware.
