Flashing Full T-Mobile Firmware Onto Verizon S8-G950U ??

Hi I'm trying to flash the T-Mobile firmware from sammobile.com, but whenever I try, I get an error at 32% when it says Installing System Update. I attempted to flash CSC,AP,BL, and CP with it saying PASS in Odin. I really need the T-Mobile firmware and am wondering if it is possible to do? I determined that I cant install CSC files and get the error when I try. Any Solutions?
SM-G950U
Odin 3.12.3
T-Mobile Firmware:
PDA: G950USQU1AQD9
CSC: G950UOYN1AQD9

I'm having the same problem with an ATT phone flash with the US "U" unlocked version firmware. When I don't flash the csc it will start up only with the USB plug in but shut down after the beginning startup

Search for a "modified Odin". It was what I used to be able to flash unlocked firmware on a 7 and 7 edge a few months ago. The "normal" Odin wouldn't let me do it, but the modified one did. Though you may need to wait until it's been updated....I haven't checked it in awhile.

Still no solution to avoid the error to 32%?

Try this Odin. This is the one I used to flash the Canadian firmware on mine.

I managed with odin version 3.12.5! But only with BL AP and CP!
When I add CSC I get the error at 32%!
So a priori everything works, I no longer have the Verizon overlay (nor the logo at startup) more by cons I have duplicates in the settings menu ...
What is the CSC file?

The Canadian firmware you got it or? On sammobile I find it not:
https://www.sammobile.com/firmwares/galaxy-s8/SM-G950U/
The Canadian firmware is stock or operator?
I would have access to all the bands?

Its the firmware with the "w" at the end. Please read this thread for all the information on doing this and make sure you want to do it.

so to do this we actually have to go to the canadian firmware first, do the csc change then flash the Tmo firmware? You can't just flash the Tmo Firmware via the modded Odin? Just to save confusion.
I would imagine it's worth it just to get the proper network options, VOLTE, WiFi calling and such.

This is the exact thread that I used. Follow the steps and you can skip engboot. If you flash the full Canadian firmware, its impossible to reverse. So, only flash whatever is in the steps. I successfully went from Verizon To T-Mobile and then back to Verizon. https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487

Need help. Oreo back to Nougat but...

I have a N950W (canadian model). Origina firmware BRA5 (latest Canadian release)
Used Odin to BRA8 then update to CRA5. Works good, however I need to go back to official Canadian release and I think it may not be possible since its BRA5?
Does BRA5 and BRA8 have different version bootloader?
Can I somehow downgrade to BRA8 but have the model go back to N950W and be recognized as a Canadian device? I am missing some needed carrier options.
Thank you for reading.

I did the exact same thing you did. Turned my W into a U model. I believe we were on 3BRA5, 3 being bootloader 3. That would mean you can flash back with no issues.
CRB5 is working great for me, but I did lose VoLTE and Samsung Pay on my Telus version (after I flashed it to a U).
Someone else chime in and correct me if I am wrong, but you should be able to flash back to W software any time without issue, as long as it's a bootloader version 3 version.

Yeah the lack of VoLTE is killing me at work. I can't flash BRA5 (I think bootloader is older). I am thinking I can maybe flash BRA8 with Canadian CSC and that will bring it back to N950W. I'm not sure though. Can someone confirm?

I just double checked. It's 3BRA5. That's bootloader 3, so you should be able to flash back to 3BRA5 with no issues. Again, a second opinion would be good. I don't want to be responsible for you bricking your Note, lol.
I don't think you can change the CSC of BRA8 to a Canadian CSC, as the multi CSCs in BRA8 are for USA carriers only.

Thanks I will give it a shot. I don't think you can brick it. It just wont load if its a downgrade.
Update: Comes up with this error in Odin, not sure if thats an issue with bootloader version

How I remembered it as is Comsy Odin is for going to a non-carrier U1 firmware, while regular odin is for going back to a carrier firmware.
Comsy --> U1 Firmware > Success
Comsy --> Carrier Firmware > Fail
Regular Odin --> Carrier Firmware > Success
Regular Odin --> U1 Firmware > Fail

ATT Note 8 on Verizon MVNO (Total Wireless) no 4G/LTE

I have a ATT Note 8 that I got the unlocked (with a the unlock code from ATT) and I have activated it on Total Wireless. I have been able to get the 3G, voice and texting to work, but I can't seem to get the 4G to work. I thought that it should work straight away, but that doesn't seem to be the case. It is a SM-N950U with firmware version N950USQU4CRF3. I tried to Odin flash the verizon firmware, but I could not get it to take (Odin refused/failed.)
If anybody could help me with this, I would appreciate it.

i have unlocked att note8, it works fine on LTE with Verizon Prepaid, 40$ for 6gb LTE data.
you have to flash a Verizon firmware with bootloader 4.
i like the unlocked firmware better, it has LTE+ to shows it connected to LTE Advanced and build in caller ID.

If you could link me to the correct firmware, that would be awesome!

here's the unlocked firmware.

When I try to flash it, it fails. https://gyazo.com/c4fd1438dee3d7f2fae1471e255763e0

Any idea why it's failing?

Which Odin did you use?
Comsey Odin or regular Odin?
Did you read the op of that link he gave you?
What's your bootloader version? Does it match or higher then the one you are flashing?
Bootloader version is the 5 number from the right of the baseband version number in about phone/software info.

I was trying to use the patched Odin 3.13 as well as Prince Comsy's Odin (both fail). The guide didn't really describe the firmware version I was running, so it was a bit hard to understand. I have bootloader 4. I have tried the firmware he linked to and I tried the latest Verizon firmware downloaded from SamFirm. Looking at the name of the firmware files, they are bootloader 4.
Thank you

I was finally able to get it to flash using a friends computer. Unfortunately all of the att stuff is still on the phone, I still have no access to 4g lte.

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
Here is the page samsung-updates.com/device/?id=SM-N960U1

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.

N-960n flash to stock att firmware

So after a bit of research it looks like it is not possible to flash stock att firmware to the n-960n. Does this sound right. I'm leaving Korea and will be going back to att when I get home.

Not officially, no. However I don't think samsung pay will work in the US on a Korean Note9 anyway, so if you unlock the bootloader and root you can flash a CSC changer to get all of the ATNT features (including voLTE/voWIFI). You will void your warranty and lose knox/Samsung Pay.

you can't flash snapdragon firmware on a exynos device. but regardless, just pop the sim and be happy. no need to change CSC for voice and data.
but if you do root as the suggested then you can get the additional csc features by flashing a csc pack.

Exactly which CSC pack can I use and where do I get it?
I am in the exact same situation: Korean SM-G960N, rooted, on AT&T's network with Android 9.
Do I extract the CSC from the latest SM-G960U1 file and flash that with Odin? Can I use an Android 10 CSC on an Android 9 phone?

Are you looking for AT&T specifically? Cause from what I know they don't release them. I used N960U since the 1 is the unlocked version software. Sorry I can't be much help beyond what I know of AT&T files. Best of luck.
