Galaxy S9/S9+ Firmware links?

I'm sure I'm not the only one who ordered the S9 from Samsung direct with the intentions of flashing it to the carriers firmware. I checked on updato and don't see it there, does anyone else know where to get the firmware? I want to use it on Sprint so I believe the CSS is SPR for Sprint.

https://www.sammobile.com/firmwares/SM-G960F/ here you go
for now there is only 1 german firmware available for download

And in case you find SamMobile too slow, I've uploaded the S9 firmware update (DBT) to AFH for having a mirror HERE

Thanks, I am in need of the US version for Sprint which the CSS I believe is SPR. I'll keep checking updato I know sammobile is super slow but if it's there and I start it now it may be done by the time I get my phone tomorrow.

Never done a carrier flash to an unlocked version. Few questions:
1. After flashing do you start getting the carrier OTA updates? And all carrier functions particularly wifi calling, visual voicemail, HD video calling start working?
2. How does the carrier fw dump work? Someone with sprint fw would have to do a carrier dump and uploads it (presumably without tinkering the content)?
3. If the file is tinkered with, since it's a signed file, the checksum would change and it wouldn't let you flash, right?? Sorry for the noob questions, just haven't done carrier flashes.

That is correct you are flashing the carriers version with their wonderful bloatware on top of it. Unfortunately for now that's the only way to get WiFi calling, VVM, and VoLTE. I just got the unlocked version today and currently downloading the Sprint firmware because without it I don't have those features. Hell LTE doesn't work on the stock version of the firmware.

Depends on the carrier. I know the s8 wifi calling and volte worked on tmobile with the unlocked firmware.

I used the SamFirm application and downloaded the Sprint firmware but yet after flashing it I still have the stock samsung firmware. I don't see any sprint software on it at all nor do I see LTE calling plus or WiFi calling. Plus on the stock firmware it will not give me any LTE data and when looking at the APN there are 2 listed but none are checked and you can't check any. It was like this out of the box before I even attempted to flash the so called Sprint variant version. I spent a good 4 1/2 hours between going to the Sprint store to get a new SIM, to calling in, and the online chat and nobody had a clue it was the same old troubleshooting steps and the best they could do was file a ticket and have someone get back to me between 24 and 48 hours. I went through this same BS when I activated the unlocked S8, the iPhone 8, and when I switched back to the S8, plus when one of our phones broke and had to switch, and now this. They can never get anything activated correctly. At least on the S8 after flashing the Sprint firmware I was able to have all the customization's but I'm not seeing it on here.

My unlocked s9 from samsung.com works on sprint lte just fine....
I do however want to flash the sprint one to get the fake VoLTE and voicemail working.

I have SM-G965U Verizon. So it I flash this will all the Verizon Boatware will be removed? And logo

You are missing the point here. Why would anyone with dual sim phone flash a ROM for single sim?! Makes no sense. Missing functions or features in the rom for the 2nd sim...

Many times.
My wife had a dual sim s8 and hated the dual sim features - found them annoying as she only uses one sim. I legitimately could not find a way to disable them. I flashed every rom I could find and dual sim features always carried over.

Can you confirm if the root is hustle firmware\OS based or system based? I don't like the idea of having to flash updates every couple of months and then re rooting the device or in my current case, I need to re unlock the boot loader and re root the phone if I update the firnware...which is bloody stupid. Proper root should be regardless the firmware.
Dpo you think we will get there with the s9? Xposed framework installed and running smoothly on Oreo?

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.

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.

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.

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.
