Question S21 Ultra ATT ---> VZW - Samsung Galaxy S21 Ultra

I unlocked my AT&T S21U and flashed it to Verizon firmware since I switched to them. I noticed my firmware build differs from the Verizon website. I downloaded the Verizon firmware from Sammobile and flashed.
See attached.
Notice the difference in build numbers.
Two main questions:
Am I on the latest version from verizon?
Will I still be able to get OTA software updates from verizon since I flashed?

I have a locked Verizon S21 Ultra with the latest update and my firmware is AUB5
Don't know if this info would help you or not.

Actually, that may. Did you update OTA via verizon system update? If so, might simply be an error on verizon's site.

My S10 just won't update..

It's an unlocked Galaxy S10 AT&T G973U..
I am using it internationally and not with an AT&T sim, so I don't try to upgrade it OTA anymore..
I tried Smart Switch, it says it's up to date. But last security patch was April 2019 and it's running Android 9.
Build and Baseband: G973USQU1ASD7 (According to SamMobile) there's no Android 10 for this baseband.
But my question is, can I flash let's say USA (Android 10) G973USQU3CTB1 or would I need to wait for the baseband for my model?
If I missed something, feel free to correct me.
Thanks!
Having a "U" model means Universal. You can flash any U.S. carrier stock firmware to it. If you have AT&T firmware and want to use T-mobile firmware instead, you can do it by flashing it with Odin.
You can get most firmwares off Sam mobile (Verizon, Sprint, T-mobile). AT&T firmware is hard to come by and you will usually have to pay to get it from a pay site like www.gsm2file.com
Just download an Android 10 firmware and flash it. No matter what it is as long as it's for the U model line.

Ok, thank you very much.
And is "USA" only unbranded? I don't want any bloatware since I am international and I don't benefit from anything they offer.
The G973U phone will only accept U.S. firmware (Verizon, Sprint, At&t, T-mobile, Spectrum, Xfinity, and unlocked U1 Samsung firmware). So if you flash the U1 unbranded firmware you will get rid of carrier bloatware.

Say I wanna get rid of the bloatware, what firmware do I select from the U1 variants? Because I see all of them have carrier names.
If you get it from sam mobile it's XAA from Unknown. The latest is the CTB5 bootloader. I think there's also a thread in the forums here that contains Odin firmware.

Here is the latest SM-G973U Android 10 firmware. It was just released yesterday morning. https://samfrew.com/download/Galaxy__S10__/f6o3/VZW/G973USQS3CTB5/G973UOYN3CTB5/

ATT S20 FE 5G Android 11 Update in USA?

Has anyone received this, as an unlocked device or one running carrier firmware? I've seen a lot of mentions that even as much as a week ago ATT released it as an OTA but I still haven't gotten anything as an unlocked phone running U firmware.
I also checked Frija and was able to pull the phone up under TMB and SPR (but not VZW or ATT obviously) and it's saying the latest firmware is still Android 10. And I can't even use SamFirm because I get that authentication error lol so is this update live or not for US/ATT?
Thanks!
I have an unlocked G781U1 converted to ATT G781U and still no update.
unlocked, running on ATT, no Android 11 update yet, not even the Jan. Security update either.
Unlocked, running on Verizon, no OneUI 3.0 update or Jan security patch.
Unlocked and no OneUI 3 joy here yet
I've been watching here...
Downloading OneUI 3.0 update now for unlocked on Verizon!!!
OneUI 3.0 showed up this morning. Unlocked phone purchased from Samsung currently on T-Mobile. I'm in AZ if that matters.
Unlocked T-Mobile sim, got One UI 3.0 this morning.
Unlocked on Mint. Received 3.0 update this morning. Installed and feels like a new phone. And no touch screen errors now. Still December security patch though.
just checked now, unlocked on AT&T....
Just started downloading here. Unlocked on Verizon.

Question G998U1UEU5BULH Firmware for 998U1

Anyone seen or have the new U1 Firmware G998U1UEU5BULH?
None of the baseband 5 firmware's have been posted yet. I'm still waiting for something to come up cause mine is stuck in a boot loop from when I tried to downgrade to 4AUIP cause I didn't know my phone updated in the background to the new baseband.
I now have a brick until a 5xxxx firmware is posted. However, 5CVAx is rumored for February 9th, but I've still been checking Frija every morning haha
The OTA's have been around for about a week now, my AT&T S21 Ultra have received it from BULE -> BULH. However, I haven't seen a standalone anywhere.
I was thinking it was probably only available via OTA right now. I am wanting to flash my VZW to U1 firmware, but I have already been bumped to the #5 BL. I will wait patiently until it appears.
I have BULH on my u1 s21 ultra with a t-mobile sim card in it. I got it about a week ago, I really haven't noticed much of a difference.
I'm with VZW and on BULJ
I'm on BULJ as well, but I like the U1 Firmware better to be honest. Just waiting on it to be posted somewhere so I can flash the U1 on my Ultra.
FYI...it's out today!

Can I flash a S10 G973U with G973U1 firmware please ?

Hi Folks,
I have bought a G973U samsung S10 but it is not receiving any updates and I am obliged to flash it with ODIN, I heard that I can technically flash G973U1 XAA firmware on it and it will update via OTA, is this true please ? I have the SPR firmware on it. Thanks for your help.
Depends on the carrier. ATT (I assume you're in the USA?), for example, won't do OTA updates unless the IMEI also matches (and maybe some other switches at ATT that we can't change).
XAA should update on some carriers, at least. My XAA updates on TotalWireless (VZ MVNO)... I've actually blocked them because I want to stay on A11 for now.
I believe you can upgrade via ODIN yourself without using an OTA - just be sure to use the HOME_CSC file because the non-home CSC will wipe your data. Any reason you're not doing that? This way, you can control your own updates and timing.
Hello Sofiene.Saidi, look at the official US firmware here for your model, the best thing for you is to take a model for your European region.

Thanks for your anwser Schwinn, actually it is fine with ODIN but each time I need to flask aprroximately 6Gb of firmware, it is somehow risky isn't it ? Can I flash USC firmware and get OTA updates please ?
If you're in France, I don't think you'll ever get OTA updates.
No, flashing the ROM a few times over the phone's life isn't going to affect the device that much. If you did it every day, then sure... but a few flashes over the life of the phone won't make much difference. I recommend you just do the updates yourself with these files and don't worry about the OTAs, because you are unlikely to get them.

Question Solved: Changing CSC from Spectrum (CHA) to T-mobile (TMB)

Hello, is it possible to change the Spectrum firmware (CHA) on my S23 SM-911U to T-mobile (TMB)? I have unlocked the phone with Spectrum but if I use with T-mobile SIM, then I don't think I'll get the OTA updates through T-mobile? On a recent unlocked AT&T Fold 3, it seemed to convert automatically from AT&T to T-mobile when I put in the T-mobile SIM...
Edit: maybe I found the answer with a little research. Use patched odin here and then latest T-mobile firmware here S911USQU1AWC8? My current firmware version is S911USQS1AWBL. Anyone have experience/tips?
Solved: I tried to flashing the multi-csc firmware with Odin hoping the t-mobile SIM would stick and force the change but the software version/branding kept coming back to spectrum no matter what. Ultimately what worked was changing the CSC with SamFW Tool by putting phone into Developer mode and enabling USB debugging and then connecting and changing CSC under ADB menu in SamFW Tool and then factory resetting the phone. Probably would've worked with no flashing needed!
You have to flash the unlocked software first (U1) then the TMB version. personally I'd keep it on the unlocked.

Ok good to know, thanks. Would it get OTA updates on the unlocked?

To my knowledge I think it gets OTA updates faster. (U1)
U1 doesn't get updates faster. In the US it generally gets updated randomly. Could be first, could be last, could be halfway through the 3 major carriers.
You will, however, get OTA updates from whichever version you flash.

That's what I thought, which is why I wanted to flash TMB especially since I was thinking about giving it to a relative later.
Well this is bizarre or is it. Don't have too much experience with this stuff. I got the software update and now the spectrum (CHA) firmware version matches the T-mobile (TMB) which is S911USQU1AWC8 but when I stick my T-mobile SIM in, the bootup logo and branding doesn't change to T-mobile and is still all Spectrum. Tried a reset with the T-mobile SIM still in and it still doesn't change. Is there a way to force this change?
You need to flash the unlocked U1 firmware FIRST, then flash the T-Mobile version.
