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.

Any unlocked USA note 9s willing to upload there modem files somewhere wanna try and make a sim unlock

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.

install Verizon "Advanced Calling" on G973U1 firmware?

Verizon is my carrier and I am upgrading to an S10 from an S7. I bought a new S10 loaded with the first Verizon version of Android 10, G973USQS2CSL1. I want to get rid of the bloatware and go back to Android 9. My plan is to flash the U1 firmware, G973U1UES2BSIV, using all 4 of the U1 files. Then flash the Verizon CSC file from this firmware, G973USQS2BSIV, so I can get the "Advanced Calling" for Verizon. I was going to try to do that on my S7 but never got around to it. Here's a thread I created on the S7 forum that said that's what I would need to do to run the unbranded firmware on the S7 but also have Verizon's Advanced Calling (wifi calling, video call, hd calling). https://forum.xda-developers.com/galaxy-s7/help/install-verizon-advanced-calling-g930u-t3997525
I noticed the S10 Verizon firmware now has a 5th file, a USERDATA file. Will I need to also flash that?
I wanted to point out, my new phone is currently locked, but Verizon automatically unlocks it after 60 days. https://www.verizon.com/about/consumer-safety/device-unlocking-policy Will it be a problem if I flash the unbranded firmware on a phone that is still locked? Since Verizon is my carrier, I will obviously be using a Verizon SIM card.
Thank for the help.

You can flash any firmware to your phone as long as it's for the U or U1 models as the "U" means Universal. Bought a phone from AT&T? Flash the Sprint or T-mobile firmware without issues. Same for Verizon and other U.S. carriers firmware.
Flashing the unbranded firmware will get rid of the bloatware, but will also get rid of other features like wifi calling, advanced calling, etc. The user data file is just all of Verizon's bloatware and info crap.
As for going back to Android 9, you can do that as long as you're still on the v2 bootloader. If you've upgraded to the v3 bootloader via OTA, you won't be able to return to Android 9.

I'm on v2 bootloader. Have you heard of flashing the VZW CSC file on top of the U1 unbranded firmware? Apparently people have done it on older devices, like the S7, that only took the 4 files when flashing. I'm trying to run unbranded firmware but still have the Verizon Advanced Calling (wifi calling, HD calling, video call).

Okay if you're on bootloader v2 then you can go back to Android 9. I haven't heard of flashing the carrier CSC file with the unbranded U1 firmware. It might work or might also brick your phone.

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/

Bought AT&T Unlocked Phone, looking for correct ROM

I'm currently living in Japan, but will be moving back to the US in a couple months, so I recently bought a refurbished Galaxy S20 FE 5g that claimed to be unlocked from the US and had it shipped to Japan.
It works fine with my Japanese sim, but came with AT&T bloatware installed and the model number is still SM-G781U. To my understanding, an unlocked phone should have a '1' after this, signifying that it's unlocked. Because of this, I don't get OTA updated and am still stick on Android 10 and One UI 2.5. So I figured I'd learn how to flash it and do that. It says the CSC is G781UOYN1ATIG, but then when I go to Service Provider it says ATT/ATT/ATT.
Could I just flash the firmware for the SM-G781U1, CSC: XAA onto it and be able to have a fully unlocked and updated phone? Sorry I'm a bit new to this and don't want to brick my phone. Thanks!

I did the opposite (from SM-G781U1 to SM-G781U) and worked with no problems. I needed ATT Wi-Fi calling that worked only with the ATT firmware when I was on Android 10. I suggest to do a factory reset when switching between branded and unbranded but (in theory) you should keep your phone data if you flash the HOME_CSC file.

Frimware S20 FE 5G

Does anyone know of a good, easy p[lace to get the firmware for our beloved Galaxy S20 FE 5G?
mine is SM-G781U (actualy purchased though Boost Mobile- Soon to Dish)
Have seen some newer sites that claim, they have the files. However, not sure why their files seem not 100% after downloading the package. About 6.1Gbs for complete Rom, so far, but not able to actually use the darn thing. Odin has issues with the files.
So, if anyone actually knows where we can get firmware for our phones, I would be rather happy.
Tanx!

No offense, but: Just search here at XDA. There are at least two good tools - 'Frija' and 'SamFirm Reborn'.

"Frija" might do the trick. I know that the samfrim is not up to date, and may have stable issues...
I thank you for the pointers

I prefer Sanfirm, the 'Reborn' version is fast and stable.

Following this post. Frija is good but can any provide info on where to get ATT Firmware?

now we can flash SM-G781U or SM-G781U1 ......SM-G781U1(factory unlocked from samsung) is the same as the G781U in all carriers.... now to get the carrier specific bloat updates or switch to other carrier to check out their bloat and updates download and only flash USER DATA file the correct SM-G781U CSC version (TMB SPR USC TMK XAS) USC is at&t in the us.... so AP BP CP and CSC from every firmware available for G781U are the same files and can be mismatched with other userdata.... now the unlocked firmware G781U1 has all carrier variant's built in triggered by Sim card insertion provisioning at boot
the website has march security update as the latest and the at&t website has two more so whenever somebody uploads latest the website will be updated and generally they are 3weeks behind the carrier..... This will not void warranty or trip Knox will not carrier unlock or unlock bootloader and if you have updated to latest bootloader rev3 then bootloader unlock is not available on the paid service

The post above says CSS=USC is ATT but that's US Cellular. I am looking for the the ATT version as I am not getting HotSpot on my unlocked FE S20 SM-G781U (XAA). I want to flash to the ATT version but when I tred the one on https://samfw.com/firmware/SM-G781U1/ATT made no difference. I see the SW version to have ATT/ATT/XAA. The trick to use *#272#IMEI*#* does not work , I do not get the preconfig. My phone was bought in the USA directly from samsung. I m suprer frustrated with ATT . Hot spot works on my wife's iphone wiht my SIM
Any pointers from some one who has got Hot Spot working that would be great. I got Wifi Calling working outof the box but no VVM
