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

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.
https://forum.xda-developers.com/showpost.php?p=77030285&postcount=1846

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.

Firmware Flash Compatibility Question

I have an AT&T variant of the S10 (SM-G973) and I wanted to flash the stock One UI ROM that is found on the unlocked S10 (SM-G970). Does anyone know if the firmware for the 970 can be flashed successfully on a 973 phone?

Why would you want to flash G970 firmware onto G973 phone? Can't you just flash G973 firmware onto your G973 phone?

My understanding is that the G973 firmware has the AT&T Bloatware and some functions/tiles hidden (like the mobile data tile for quick settings). I'm hoping I can do the stock firmware from G970 to not deal with the bloatware and have more access.

Have you thought about using unlocked G973 firmware? G970 is S10e model

Thank you, Charkatar. I bet if I paid more attention in my search I would have noticed the difference. Next step, find and flash the unlocked firmware!

Use SamFirm tool to download firmware you need ( I have attached zip file) and check out example image on how to search and download firmware your phone needs.
So under model, you would put SM-G973U1 (which should be unlocked model) and region you would put XAA (unlocked model) and click "check update" IF YOUR MODEL IS DIFFERENT FROM MY EXAMPLE, THEN ENTER THE CORRECT MODEL AND REGION YOU NEED

I'm on a Mac and can't open the windows .exe files. I did find a slight work around with Samsung SmartSwitch. Work has been so busy I haven't had time to find and download the U1 firmware for the S10. I"ll let you know how it goes!

G991U and G991U1 Firmware Links and Flashing Discussion Here

For those who aren't already aware, G991U is the model number of all of the US carrier versions of the S21. The G991U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. A "U to U" or "U1 to U1" flash does not require a factory reset, but changing from one firmware to the other will require one. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.
Manual Odin flashing is designed for those who:
- want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
- want to flash U1 firmware to their U device
- want to convert from U1 firmware to carrier U firmware
- want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)
For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via the various firmware download tools posted here on XDA like SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I pay for a subscription to a site that gets the official releases (usually) before they hit the firmware download tools, so that's where my files come from.
This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware (or haven't done it in a long time), I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.
Happy flashing!
U firmware: https://www.androidfilehost.com/?w=files&flid=322084
U1 firmware: https://www.androidfilehost.com/?w=files&flid=322085
Notes:
- DON'T QUOTE THE OP WHEN YOU REPLY, kthx
- I have lots of threads just like this one for other Samsung flagships, if it interests you. For those who have already made use of my previous threads for a different device and are upgrading to an S21, welcome back
- My zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- it's quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single Sx and Note x model - so I won't be uploading every single version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit the firmware download tools.
- My naming method for folders on AFH is: build - bootloader - Android version
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.
- HOME CSC file keeps data intact; using the other CSC will wipe data. Flashing USERDATA will also wipe data.
- Since AT&T doesn't allow their firmware to be publicly available (for any of their devices), I'll try to always upload at least one USERDATA per bootloader increment for AT&T (and Cricket, if they get this model). I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.
- For identifying USERDATAS, and to know what region/CSC to use in the firmware download tools if you're downloading yourself:
AIO = Cricket (not available via firmware download tools)
ATT = AT&T (not available via firmware download tools)
BST = Boost Mobile
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
SPR = Sprint
TMB = T-Mobile
TMK = Metro PCS
USC = US Cellular
VZW = Verizon (available via firmware download tools, but Manual Entry is required - Auto will not work)
XAA = U1 firmware
- the correct procedure for switching from one carrier's firmware to another is:
1. Flash full U1 firmware package including non HOME CSC
2. Upon boot, insert a SIM of the carrier whose firmware you want
3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it
4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want

Initial U firmware and AT&T USERDATA are posted, along with U1 firmware. U firmware is not yet accessible in the firmware download tools like SamFirm and Frija, but if anyone wants a different carrier's USERDATA (for flashing bloatware to a U1 device or for converting a U device from one carrier's bloatware to a different one), let me know and I'll get it for you

Thanks for the firmware links!
Odin blocks flashing from U to U1 or U1 to U. To successfully flash: Use the patched/modded odin found here.
Patched Odin 3.13.1
For those looking for a modified, modded, or patched odin that is a newer build than all the fake and renamed prince comsy 3.12.3 versions floating around. I patch recent Odin versions to offer similar functionality to the princecomsy; in that...

Hey guys, I'm curious if anybody could help me fix an issue I'm having with flashing. I'm trying to flash from the U variant to the U1 but it seems to be csc locked to TMB. I've tried multiple firmwares, pulling the sim out before flashing and even flashing back and forth from U to U1 I can't seem to get the carrier update pop-up at all. I'm kinda at a loss and would appreciate any help you guys could give me

Are you saying the service provider codes stay as TMB/TMB/TMB, even after you flash U1?

Yes the csc is locked to TMB for some reason. I did the full csc non home flash several times with no luck

If you mean a PIT file, that's already included in the CSC file. So that is flashed, if you flash that file

So it's relatively the same concept but you use the csc file in the pit section?

Update: I'm completely lost. I downloaded the Canadian firmware which gave me the xac csc then I flashed back to U1 which also updated to Xaa. But I still showed only t-mobile n41 and 71 bands so I flashed back to U with Verizon bloatware and now I have a Verizon U firmware with xaa csc and still only showing t-mobile bands

I don't guarantee that any particular bands will work on any particular firmware. Also, carriers don't use every single band in every single area

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.

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

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.
