So I was recently in the US on holiday and got an S21 Ultra. The US Version SM-G998U. I however only ever turned on my phone when I returned to my home country in Africa. Sadly it seems I'm cutoff from any and all OTA updates. Contacted Samsung and they said they couldn't do anything. So I researched how to flash new updates myself. Is there a way to flash my phone where I'll be able to now get OTA updates? Or I'll have to be doing it for the rest my phone's life? And when I go to Sammobile to look for the firmware file, I can't seem to find any files with GCF indicated in the name. Which firmware update can work for me based on the GCF/GCF/VZW regional code?

As you have a US Snapdragon S21U you are limited to firmware for G998U and G998U1 phones.
See following threat:

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%...

maybe your USB cable is the issue if it won't connect. Are you using a high quality (can fast charge) USB-A to C cable?
Verizon locks down their phones - super annoying.
Any luck with your phone? I also have GCF/GCF CSC code and no updates. In addition all files that I have tried flashing with Odin have failed

Long story short. I have purchased a brand new imported UK Galaxy Note 8 SM-N950F. Upon opening the brand new box, I got nothing out of the ordinary. Booted the phone and what do you know? It's locked on Vodafone UK... (it didn't accept my Vodafone RO sim for some reason). Talked with the guy, the guy freaked out because he sent me the wrong device and told me I'll get a phone unlock code within the next 3 days.
After I'll unlock the device, I wonder. Can I flash a normal, non bloated BTU firmware onto the phone over the UK VOD firmware that's currently on it? I adore the device but I ****ing hate being stuck with carrier **** especially knowing that Samsung is slow with updates and it being a carrier based firmware, it will be slower also. On my old S8+ I did the same.. worked like a charm, Knox not tripped, phone was running stock non bloated firmware and to this date is receiving updates normally and is working properly.
I heard that Samsung has decided to region lock the devices from S9 forward (or was it Note 8?) but I'm not worried as I like the UK firmware.
TL;DR: Got a Note 8 UK Vodafone locked phone. Can I flash over the UK VOD firmware, a normal BTU firmware?
I am asking strictly because I heard that the Note 8 might be region locked and that could maybe interfere with my plans.
its not region locked.
Yes, you can!
And I wouldn't worry about the region lock. Because UK and Romania are both EU countries and the region lock is enforced for the greater EU area.
This is what it shows on Eu Region Lock devices.

Hello,
Sorry if this has been asked, but i can't seem to find the same question anywhere else.
I have a Samsung Galaxy A715F/DS (vietnam) branded International Unlocked Phone, but i live in the USA... I see many firmware updates for this phone at SamMobile site, Is there a firmware i can use that will allow the phone to be more compatible for the USA use? and is it possible to flash a different country firmware with the same model number on this phone instead of using the Vietnam version? i'm well familiar with flashing firmwares, i'm just not familiar with different county firmware updates. Help please any suggestion or advice would be appreciative. Thank you

And what exactly is "the USA use"? You use it sideways over there?
Have the same version of the phone with XME (Malaysia) firmware installed. Try out the firmware TGY (Hong Kong) and no problem encounter. The only different is that different countries have their own type of software packages. Hope this help.

Samsung apps are based on the country code of your firmware. I'm interested in changing Samsung Pay so MST works because right now I am on UAE firmware and MST did not work when registering with the UAE version of the app. My rewards/offers for SPay are also in their currency, not US, so for now I am using Google Pay because I don't want to wipe my phone and try a bunch of different firmwares. Samsung's country codes make all this very complicated.
If someone has found a firmware compatible with USA Samsung Pay and US Samsung apps, please share.
Good day! Could somebody help me with my A715F/DS? After I updated via OTA, it bootloops and all other firmware from SamMobile is not working though ODIN - PASS but after reboot, the bootloop issue still exist. I attached all the firmware I used to flash via ODIN.

Greetings,
I have an SM-G998B/DS, which was bought closed carrier unlocked, but with a firmware from Vodafone (Comes with 3 Vodafone apps which are easy to uninstall). Also the Active CSC code = ATL.
I am from Spain, so I wanted to flash the firmware with the one which says PHE, thi sone in particular

File downloaded:

Thing is that I flashed without issues, but I still see that Vodafone apps gets installed and in the Phone Info APP still says ATL
My understanding is that by flashing with PHE, the firmware would not be tied to any carrier in particular? And it should show as PHE in the phone INFO app?
Also, I always have seen the CSC blank, even before flashing, except for the "Active CSC". Is that normal?
Thanks in advance!
Out of curiosity, Whats your software provider software version?
I.e. TGY/TGY,TGY/BRI
Greetings,
I am attaching a screenshot.
Thanks!

Hi
Changing the active CSC is not as easy as it use to be, before just flashing the correct firmware and booting the phone with the right SIM was enough
There are a couple of options using a dialer code , myself i used that method to change from GTO to PHE , I see you have the latest firmware I do not think they will work anymore , you can try if you want check here
If that does not work your only option without root is samkey ( pay)
Thanks for the reply!
I think I will just leave as it is. I can survive with 3 additional apps which I can uninstall.
Thanks again
My S21 Ultra purchased new from Amazon arrived earlier, however what I noticed was that during setup was prompted to install operator resources, which could not be bypassed. I initially presumed it was because I had my sim in, so factory reset and re-installed without the sim, but same deal.
Weird that the s21 ultra from amazon (was brand new) came with three.co.uk Carrier branding.
Anywhoo I downloaded the latest unbranded firmware

I gave up and started a return back to Amazon. Shouldn't have arrived brand new from Amazon with carrier branding on it!
It depends, IMHO, on what the Amazon seller promised you: just an unlocked or an unlocked & unbranded device. Branding is done in factory by Samsung.
Not necessarily anything wrong with a branded phone. It can/should still be brand new. You may only be bothered by the bootlogo on startup (look away) and Three-related apps can be deleted or switched off/disabled.

SInce around August 2020 it has not been possible to change CSC code by flashing via ODIN.
There is a paid-for service on "SamKey". Do a search.
when using samkey, u have to remove sim cards, then change csc via samkey,
once done, download BTU firmware, use odin, remember to go to recovery format and clean cash
and your good to go
Thanks peeps for all the replies, extremely informative
Received the replacement yesterday, decided to bump up the storage from 128 to 256gb.
Thankfully on boot and shutdown no more carrier branding on the replacement device!

Typically, in the US, the U1 version will change CSC when you install a working SIM from a different carrier. Of course, this won't work for you since you won't have a US carrier SIM. There may be ways to force-change the CSC on Snapdragon, but I haven't found them to work.
What's weird is that your phone already appears to be a multi-CSC ROM (you can see this in the "XAA" for the CSCs there). So you don't need a new ROM, but you still need to find a way to actually force the switch. I'm not sure if that's possible.
Note that per your CSC, this was originally a VZW (Verizon) phone, and is only "currently" an SPR phone... because it doesn't see a matching CSC to work with.
Anyway, all that said, I don't believe USA phones can have native call recording either. USA laws are crazy in this regard, so I don't know if any ROM will allow that here. That being said, I have been using BoldBeast recorder on my Android 11 phone and it works great. I do believe it won't work on A12, which is part of the reason I have not upgraded my phone to A12. You may want to give that a try, anyway, to see if it can work?

i think because the company unlocked the phone for the user after he paid the full price
before that the device was locked to their career
