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

Note8 Question/Concern

Can I get Wi-Fi Calling on an unlocked Note8 bought from the official Samsung website? Don't want to get the T-Mobile variant because of the bloatware and boot up animations. I also don't like the T-Mobile status bar data icons.

Assuming you have an N950U yes, just download the T-Mobile version firmware and flash that. It will include those things you don't want, however.
The only other way to get their wifi calling would be to root and flash the full CSC + any missing apps/libraries/etc

STOP... Please use the search option.... been answered countless times.
I have unlocked n8 from Samsung usa. I put t-mobile SIM. Volte and WiFi calling work right out of the box.
No need to flash any firmware

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.

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

[Doubts] Remove all Bloatware (COMBINATION File process).

Hi.
I need to remove all Bloatware, from my Note9
I think one way to do it, is installing the N960U1 Firmware (USA unbranded)
Reading on the Internet and watching videos on YouTube, I obtained the following procedure:
My Note9:
Model: SM-N960U (AT&T)
FW: N960USQS1ARI5
1- Flash Stock Firmware (N960USQS1ARI5) and make a Wipe Data/Factory Reset
2- Flash CSC from Firmware (N960U1UEU1ARJ5)
3- Flash COMBINATION File (COMBINATION_FAC_FA81_N960USQU1ARG4)
Enter - Menu - Factory IME
Press *#243203855#
Select CSC = XAA (in my case)
Reboot
4- In ADB Shell, enter the following command: echo "XAA" > /efs/imei/mps_code.dat
5- Flash Stock Firmware (N960U1UEU1ARJ5)
6- Wipe Data/Factory Reset
7- Done
This is a summary procedure (without details), but...It is right?
I have a doubt with step 4...
Why is it done?
Is it necessary to do it?
Thank you.

Flashing stock firmware isn't going to help, there will be no Samsung provided Firmware without the bloat.
To remove the bloat, it's actually much easier than before, thanks to these recent versions of Android.
All you need to do is open an ADB Shell and paste in the contents of the quoted text in the first post in this thread. This will disable almost all bloat but personally, there are a couple parts of the bloat I like to keep, so I omit a few of the lines.

What bloatware are you wanting to remove?

I agree with you, "Flashing stock firmware is not going to help"...but, I will change from custom to Operator to un-customized.
and Maybe later, the list (Galaxy Note 9 Bloatware Removal Thread) that you mention can be shorten a little more.

Correct. Just flash the U1 firmware. If you're on ATT theres no reason to mess with the CSC. You wouldn't want to anyway.

Yep, I flashed the U1 non-carrier specific firmware with the patched Odin yesterday. Absolutely no problems, ATT 4G LTE still works (even a little faster than before), Wifi Hotspot now works, and no ATT bloatware anymore (I re-installed Visual Voicemail from ATT, that is the only ATT specific app i have now). I even got two or three OTA updates for security right away.

Your answers are in his photo he attached. He obviously has the ATT carrier-branded Note 9 model N960U, same as you.
He flashed software build N960U1UEU1ARJ5.

what others said is correct, just flash u1 in modified odin and ull be on xaa with little or no bloat..
the dialer code is nice to do it on the fly.. u can use it to only apply network settings or change the brand or both..
the adb commands are not needed at all.. i also am pretty sure they dont work at all (permission denied) on note 9..
keep in mind pie builds are different.. i dont think it matters what u flash, it changes based on sim inserted.. the csc code also doesnt work on latest pie builds so no way to change it up unless u put in another sim card.. i think one of the earlier pie builds i was on the csc dialer code worked..
on latest pie build i notice a new line in dl mode, anyone by chance know what "KG Status" is?

Nand Erase All
When is it recommended to use those options?

Search here through the forums. The files are linked in a few threads, as are the instructions.
You could just Google ODIN instructions and find it.

One UI 3.0 can be loaded on SM-F916U1

I'm using an unlocked U1 on T-mobile US and just used the google dialer to switch CSC to XAR (Which I don't think you HAVE to do). Just use frija and download SM-F916W region XAC and use Odin patched. Up and running with no issues.
**updated i actually used model SM-F916W region XAC in Frija.

did you have to wipe your phone? Same on T-Mobile and getting antsy waiting

Is there any drawbacks whatsoever for changing your CSC?
Or let me rephrase, do you still have 5G, Wifi Calling, samsung pay, etc.?

Which CSC did you use when searching in Frija? XAR returns no results for the SM-F916W.
XAC?

After looking on Frija I'm seeing XAR is for SM-F916U1 and it's US based Android 10. Not sure how you got Android 11. If you meant XAC there's no option to change the CSC to that.

My apologies i was running on very little sleep. I did indeed use XAC in Frija. So I suppose you could try leaving it on TMB and flashing since i flashed the XAC version for SM-F916W over XAR on my U1. I do have a bunch of extra dev options though that i'm not sure would be exactly the same. I will confirm later but so far, I haven't found a dialer code on XAR that works to change CSC on version CTLL with XAC. But your sim will automatically flip your network CSC to TMB regardless. I'll update my previous posts thanks for the catch.

Like i mentioned in my post above, so far, I haven't found a dialer code that opens up the CSC menu on the new version. I'm going to try again shortly but your sim will automatically set your network to TMB. I can say that VOLTE and WFC works much more efficiently for me on the new version. You just have to wait for setup to complete and the WFC option will appear as usual.

ODIN allowed you to flash SM-F916W firmware on a SM-F916U1 model? Typically cross flashing between models fails when using ODIN and even if it let you, you'd probably be soft-bricked.

This does work. I have tried it. My fold 2 was bought from Samsung unlocked. It now shows the device as SM-F916W. I am with AT&T and 5g doesn't show up but everything else seems to run just fine.
I was also able to go back to u1 firmware with CSC XAA .

Yeah the patched ODIN 3.1.4 did work in this case. I did some checking of the partitioning among various regions/versions and the canadian version didn't really require any changes so i thought i'd take a chance. I do have 5G so that tells me you need to apply sales/network CSC of something that isn't carrier locked prior to updating and everything should work ok. That's speculation and my personal experience.

This isn't surprising at all. Since the Galaxy S8 and Note 8, the U models and the W models have all been cross compatible with firmware. They are actually the same exact device, and the W only indicates it's running Canadian firmware. Just like the U1 indicates it's non-carrier branded and U indicates it's a carrier model. No issues cross flashing at all.

916B and 916U are not the same devices. There are hardware differences, so you can't crossflash firmware.

Flashing firmware doesn't do anything to affect the locked or unlocked status. Many, many people here have flashed U1 firmware on locked U devices over the last few years.

I honestly have no idea. I'd check some of the other Samsung forums, like the Note 20 or Note 10 forums.you may find an answer there as they are more popular devices.

I actually went and flashed my u1 to this version .. everything else works as it should but so far my only drawback is that my samsung sofi account has been deleted after it updated to samsung pay Canada...
Edit: although it samsung pay Canada all I had to the was verify my samsung password and accept samsung pass terms and I was good to go everything is there and works as it should.
