You can flash it using modded or patched ODIN to the U1 non-carrier firmware to get rid of the T-Mobile boot animation. It will also remove the T-Mobile video calling dialer though but WiFi Calling will still work.

What he said^^^ flash the U1 firmware. Note your device will be wiped.

Well that doesn't matter to me. Have never used it yet so it doesn't matter if I wipe it. But will I get regular updates if I flash it with u1 firmware ?
And which firmware should I select it exists a few on this page or do I need to take the tmb one for T-Mobile but I'm not using T-Mobile and will probably never do

Do not use the one labeled TMB U1. That firmware isn't official and could potentially break OTA's. You want to use the U1 XAA with the same version or newer bootloader than what your device currently has. The the first character of the last five characters of the build number contains your bootloader version. I don't believe the Note 9 has a v2 bootloader yet, but I have only really followed ATT U firmware, U1 firmware, and TMB U firmware. When you flash, do not use the HOME_CSC! remember your device will be wiped and factor reset so back up what you want before starting.

I'm running the TMB U1 firmware. No bloat or boot screens and I get OTAs around the same time as the U t mobile devices. I honestly dont see a real difference from the XAA u1 vs the TMB U1 firmware to be honest

Well that's it's not a problem haven't started to use the device yet. But it's not any risk that I'm brick my phone when flashing with u1 firmware.
One thing I noticed it exists unbranded firmware what I can see on Samsung's page for n960U can I not use that firmware ?
But I should not flash home_csc ? I'm guessing that contains special files for u1 ?

The non-branded firmware is the U1. The reason the modded or patched ODIN is needed is to skip the check that you are flashing the same carrier firmware. The hardware for the US and Canadian models are exactly the same. The firmware on Sansung's page isn't meant for flashing in ODIN.
Although I have only seen one user experience issues with the TMB U1, which for some reason, gave him a modded software warning when they tried to check for updates. I would stick to using the actual non-carrier specific firmware, which has T-Mobile's WiFi Calling and still has band 71 enabled.

ok so the SM-N960U is carrier branded and the SM-N960U version ubranded i thought it was some more technical difference between the different models.
Well the phone i have is new just carrierd unlocked but it's coming from t-mobile but i'm not going to use it in usa right now. So unless i need to have t-mobile's software i gladly skip it and use unbranded and that is the "U1 XAA" i need to use ?

The U is carrier specific, the U1 is a generic non-carrier specific firmware that should work with most US carriers, and the W is the Canadian equivalent of the U1. The hardware for all three is exactly the same.
The unbranded and non-carrier specific firmware does have its advantages. No carrier bloat, it works well with T-Mobile, and if you switch carriers, the phone will reconfigure for the SIM inserted. The only time the U firmware is recommended is if you need a specific feature for a particular carrier that isn't available in the U1 firmware. Video Calling for T-Mobile, WiFi Calling on AT&T, and so on.

Ok so with other words i can use the unbranded XAA firmware and keep OTA now. But if i ever want to use T-mobile or AT&T further on i just install corresponding firmware for that carrier right ?

That's correct! The U1 non-carrier firmware is like a stepping stone, If you want to move from one U firmware to one from a different carrier, you need to flash to U1 first and always make sure you never use the HOME_CSC. The HOME_CSC doesn't wipe the device, which can cause a number of issues when converting. Being on the U1 though, makes it very easy to go back to any U firmware because you are already at the point where you could just straight flash to any U or W firmware as long as the bootloader version is the same or newer than what your device has at that time.

ok thanks for all advice
just to be curious because i don't know but wish to learn. Why should u never flash hone_csc and what does that file do?

The HOME_CSC prevents wiping while flashing. If you skip the wiping part, you risk having no data, no potential cellular connectivity, no different unlocked bands for the firmware you are flashing to, etc. You pretty much put yourself in a position where you have to flash again, but actually use the other CSC to ensure your device works properly.

Hello all. I am new to this community. I have read several of the posts that mention that the US Snapdragon variant of the Note 9 cannot be flashed with TWRP or custom roms. However I see that based on this post regarding T-Mobile that the U1/ublocked variant can be flashed with any of the other U variants as long as the bootloader is the same. Does this mean that I can flash the T-Mobile firmware on my unlocked note 9? If so can anybody guide me on how to do this? I am trying to go back to having T-Mobile's built in multiline and voicemail functionality which I lost after going from the T-Mobile branded Note 8 to the unlocked Note 9. Thanks!

Yes you can. Use ODIN to flash the T-Mobile firmware. It's that simple. You don't need an unlocked bootloader or root. No it won't trigger Knox.
If you need detailed instructions, they have been posted in some of the firmware threads here, o you can go to the Note 8 forums and read through the carrier switching thread. Just follow the steps for flashing carrier firmware. The steps are all the same, you just make sure you're using the right firmware for your device.

Thank you so much! I was able to successfully flash to T-Mobile using the forum threads.

That's because U1 XAA is on ARJ9. There won't be a U1 Firmware with an ARH6 build number.

Accidentally bought G970U instead of G970U1

As per the title, bought an unlocked G970U instead of U1 by mistake. Should I expect a Verizon splash screen greeting me in the bootloader? I don't wanna see any branding anywhere in my phone. Can I get rid of any of that flashing U1 firmware?

Which G970U phone you have bought. If it was a Verizon branded, then their logo should greet you If you bought T-Mobile variant, then its logo will be present while booting the phone. Flashing is possible and it depends which carrier you have. Also don't you have the phone in hand yet?

Yeah, the phone hasn't arrived yet. In the pictures I can see the box has no carrier logo, but I'm guessing it's Verizon because I haven't seen a Verizon branded box yet. Also, the box definitely says G970U.
I've been a Nexus/Pixel user all my flashing life, so I'm well versed in the fastboot/adb dark arts. How does this compare to Odin? There are so many new terms that I'm still trying to understand: CSC, HOME CSC, USERDATA, etc. Is there any guide I can follow to flash my incoming phone to U1 firmware?

The T-Mobile version is also G970U, so it can be pretty much any carrier. USERDATA file is present in carrier firmware, if you flash unlocked firmware you won't need/have this file.
Link below is for S8, but works for S10 as well. Of course you would need to use firmware files for your phone. I would also use instructions under "Flashing standard firmware" first using Standard Odin. If you get an error when staring to flash, then use (Patched) Prince Comsy's Odin.

Thanks a lot. One last question. I'm based in Mexico (we only get Exynos here), so I got a U version to get the Snapdragon CPU. Obviously I don't want any US carrier branding/blotware in the phone since I couldn't benefit whatsoever from it. What about OTA's, though? Will I get them whenever Samsung releases an update for U1? Or will that depend on my carrier? Should I update monthly using Odin? Do I have to factory reset? So many questions :silly:
The link you provided doesn't work, btw. But I've since found some other Odin guides. Thanks!

I corrected the link in case you need it.
To answer OTA question: I had unlocked U1 model of S8 and when I flashed it with T-Mobile firmware then my phone got OTA from T-Mobile when they release it. I assume if you have carrier branded phone and flash it with U1(XAA) firmware then most likely your phone will get updates when Samsung releases them. You won't have to use Odin every time there is an update if you flash properly. Also, it would be advisable to flash using CSC file instead of HOME CSC, so your phone would be wiped. It is because you change firmware and want your software to be fully compatible. After flashing and you check your phone's software update and see that is shows "not compatible or something similar", then I would just suggest you to do "reset"(factory reset) from setting and after you setup your phone, that message will disappear. Also don't do any software update before flashing as you phone may get a fresher firmware than the one you might be trying to flash.
1) Check your current phone firmware
2) Download firmware you want, but if you can, get the firmware that is a previous one than the current one, so you will check to see how your phone gets OTAs
3) Flash using Odin
4) After that disconnect and let the phone do its thing
5) Set it up and check to see if software update section in settings don't give you any messages such as the one I outlined above, if it does, just factory reset the phone

Questions about flashing unlocked firmware to my G973U

Please excuse any mistakes I make as this was my first time flashing firmware. So anyway, I have a Verizon S10. I got tired of Verizon’s bloat and all the missing stock features so I flashed the Unlocked Firmware from Sammobile. As I had no prior experience, I did research and came to download the latest U1 firmware with the XAA CSC. I know there’s a U1 version with the Verizon CSC, but I decided to use the XAA version because I knew it was universal. Now I could be totally wrong on this, but isn’t at least one of the three CSCs supposed to be XAA? All mine are still VZW, just like it was on the original carrier fw. I even tried taking the Sim out and reflashing, but no luck. The phone is still locked to Verizon, could that be why? The problem is, can I still get OTA updates? How can I stay on unlocked firmware and get them? Did I mess up and should’ve flashed the VZW U1 fw? Is this fw all vzw cscs too and I just messed up somewhere else? I have the pda of the xaa version with the csc of the vzw version. I don’t know what to do. I would’ve loved to install the one ui beta now that I’m in unlocked fw, but I can’t because my active csc is version, who blocked it

Some answers to your questions:
1. I don't know, it should flash a data partition that's for the unlocked firmware. I remember reading that somewhere here in the forums.
2. I think Verizon phones are more locked than the others, but I could be wrong.
3. You can get the OTA updates on the unlocked firmware, you just have to have a SIM inserted.
4. You may have, do a factory reset in recovery and try flashing this with that special version of ODIN:

5. U and U1 firmware are different, sort of. U is carrier and U1 is unlocked.

Question Which CSC code to use

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.

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.
