Hey guys,
Bought the galaxy s8 plus from a store thinking it was factory unlocked version directly from samsung, but it wasnt. Its the unlocked sprint version based on the radio, and it had a tmobile app or two already installed. I am using AT&T and would like to change the carrier to at&t so that I can get a few features for at&t (Mainly being able to send mms while on wifi). I updated to the latest online update (which im guessing i shouldnt have) and i would like to know if its possible to easily change the carrier still, and or if i can downgrade safely to change the carrier. If so, what files are the latest that I can get the ball rolling with? Using the AT&T version is completely fine.
I came across this youtube video that shows how to easily change carrier without flashing: https://www.youtube.com/watch?v=msAHhCVF-F8
Basically i am a bit lost and would like to know if anyone can help at this point. Here are my software information:
Bootloader Version: G955USQU1AQGL
Build number NRD90M.G955USQU1AQGL
Active CSC Code: XAS
Please advise, thanks guys!

Goto updato.com to download the latest AT&T stock firmware. Extract and flash the files in Odin. If you flash all the files (AP, BL, CP And CSC) you will wipe everything on the phone so backup first. If you don't want to start over, then just flash CP and CSC.
There are two versions, 955U and 955U1. The U version is carrier specific and will contain their own software bloat. The U1 version is unbranded so no carrier bloat.
If you need more details, search for carrier switch.

Hey my friend,
Thanks so much for reaching back with an update and for the support! Awesome! So, youre 100% sure downgrade procedure wont brick the device? Also, do you know if this will this trip knox? Last question: do you think this will solve the red tint on the edges of the phone? I heard this was supposedly a software issue, not hardware.

Ok, so I tried it and with the unbranded XAA version and I am getting a "FAIL! Model dismatch fail" in odin. Even tried renaming files to tar and removing md5 at the end.
I also noticed that when in download mode, there are no green words going across the screen like I see in youtube videos who get it after they connect it. Could it be i do not have specific drivers installed? I installed the samsung usb drivers.
EDIT: Scratch that, the odin PrinceComsy version (Has to have the banner at the top) seems to be working fine. I am currently flashing

Download quick reboot for your phone and use the app to get into download mode. Make sure you have debug settings turned on in phone. Also check if you can access the phone when its plugged into your computer. If you see it as a drive, then the drivers were installed correctly. If not, uninstall and reinstall.

Awesome. ok, so i got it to work. But now when i reflash the rom back for sprint, the splash screen is stuck to AT&T and does not remove or go unbranded no matter what i do. It even has bloatware for att when the system starts. I never flashed att rom, only sprint unbranded XAS, not sure how this is happening. How can i get unlocked gsm and cdma back unbranded for sprint? I even formatted everything and flashed the user data, still the same. Its weird
Also, I am flashing it back to return the phone to store the way I received it. This red tint is just unacceptable.

You need to flash the XAA not XAS U1 firmware.

Yes that firmware is unbranded. The CSC from XAA will automatically detect your carrier's sim and use that network.

Ok, so just tried it and the sprint CDMA is no longer available in the Mobile Networks menu., only the following:
Mobile Data
International Data Roamin
Disable 2G
Access Point Names
Network Operators (AT&T underneath)
There is no option to choose CDMA like there was before I just firmware changed. The XAS firmware that I had offered the option to choose automatic, LTE/3G, CDMA. Now its gone from the menu after the XAA flash.

Hey bud,
Thanks for this. My actual carrier is AT&T, but id like to keep the option of having CDMA available if I ever decide to go with sprint. I have the app installed, When i tried to launch Preconfig (com.sec.android.Preconfig.Preconfig) and it gives an error "su: not found"

Forgot you have to be rooted use the app. There's an adb command you can use instead. Just do a search in xda for preconfig carrier switch.
I flashed my spring s8 plus with Odin and now I can't get it to read my sim at all ,says will not register on network , where the carrier usually is it says 12345 , I've tried to flash back to stock and nothing works ...im at a loss this is my only phone ,I've tried to do a stock reflash and still nothing , I even did a emergency recovery through smart switch and still ...please help

Thanks a bunch! I've been trying to download it with no success
Thank you. Time to tinker again...haha
Yeah I'm gonna get this rooted and hopefully get some performance back after UPDATE: i rooted successfully but after i tried to fix the fingerprint sensor issue my phone would only boot to recovery and download mode so i flashed to stock
It turns out that when I flashed those files it kept trying to activate my phone on the sprint network instead of att and also it made my settings go wonky so I'm downloading the u firmware with the att product code again because it messed it all up
Just a heads up, I was unable to get the EngBoot Kernel working on this ROM. It would reboot on its own every 2-3 minutes. I spent about 6 hours on this until I gave up and flashed the ATT ROM and then EngBoot. That worked just fine (except for the performance issues).

Can you link to ATT Nougat EngBoot rom? I wanted to upgrade to Nougat, wipe, and then get Nougat EngBoot rom on their, but I don't want to use Sprint or whatever that other carrier was. (Prefer to use ATT on ATT devices, ya know?)

If I'm using a G930T but using Cricket at my carrier should I flash this or.the TMO variant that you posted in the T-Mobile S7 forum?

I don't know if it will make any difference but I would try the t-mo version to match your device.
Help!!! I went ahead and flashed the TMO version of the 930u code. I downloaded the ZIP. Placed all the right files in the correct place in Odin (comsey odin) and finished the process. The phone didn't reboot even though reboot was checked. Now I'm in a boot loop. Help!!
Update:. For it to work after flashing a second time. Not sure what happened the first time.

Does anyone have an idea when the unlocked US models will be getting the Pie update? I'm on Sprint if that makes a difference. Kind of sucks that everyone is getting the updates but unlocked phones are not.

Sprint has already rolled out the carrier locked update. The u1 should be rolling out in the next day or two.

I'm in the same boat. I'm with an mnvo and I have to stay on u1 firmware to retain VoLTE as they block simultaneous calls and data on BYOP plans.
For some reason u1 stayed on ark5 for me with Nov 1 patch. I have att phone where I loaded u1 before. No further updates. I saw posts that u1 has dec patch. Am I missing something?
I'm also waiting for ota to see when it hits my phone. Not in a hurry.

That's because the AT&T devices are locked. You can flash u1 firmware all day long, but you can't change the locked CSC (where the device looks for software updates). The phone is looking for u1 firmware from a carrier that doesn't provide firmware for the U1. If the device is paid off, ask AT&T to remove the Sim lock on the phone. You maybe able to change CSC forcibly, but I think you may trip the Knox counter.

It was already unlocked which is how I was using it on T-Mobile. I did a weird thing in December. I updated to android pie beta and due to some issues with apps I tried reverting back to Oreo. But I did multiple tries using odin and didn't work. Then I read through online and found that to go from pie beta to Oreo we have to downgrade using samsung switch as bootloader is different. That's when things might have been messed up. Any suggestions or thoughts on how I can get it back to pure u1 with updates?
Attached my current software details
I've never hear of needing to use smart switch to jump bootloaders as I don't think that's even possible on a locked bootloader. Once the bootloader changes, there is no going back.
So was your phone originally a U1 device or a U? What firmware are you currently on?

Edit: I see your screenshot. What is sticking out at me is your CSC. I see ATT/ATT/TMB. I'm not seeing XAA like an unlocked phone would have. If I'm not mistaken, once you attach your phone to ATT or TMB, you essentially lock your CSC to their network.
When you flashed back to u1 firmware from the pie beta, you didn't use Odin, correct? If you didn't use Odin. I don't think smart switch will reset your CSC to XAA.
My best advice would be to download the U1 ARL1 Odin firmware files and flash the CSC (Not HOME_CSC). You will have to wipe your phone, but that will put you to the latest U1 firmware and back to unlocked CSC and will point it in the right direction for future OTA updates.
---------- Post added at 02:37 PM ---------- Previous post was at 02:33 PM ----------
Just an FYI, I flashed my phone from the pie beta to the U1 ARL1 odin file with no issues. Today I flashed my other s9 plus from brk2 (carrier) to u1 and had ODIN give me some fuss using the same method/firmware I used on my other phone. If Odin is failing, put the phone in download mode and connect it to ODIN, loaded and ready to flash... Hold power, volume down, and bixby until the phone reboots back into download mode, ODIN will connect again, unplug the phone and plug it back in, THEN flash. It's an odd sequence, but it works.

Thank you for detailed explanation and questions.
My phone is originally att which will be u device. If you remember or heard of it, back in April we had att phones in Samsung site for 650$ and that's where I bought it. I was never on att Network so I submitted for unlock and meanwhile installed u1 from xda
then I unlocked and used tmobile sim. It always got ota as expected. In November I signed up for Samsung pie beta and then did an ota to pie.
When I wanted to revert back, I downloaded latest u1 and installed through odin it didn't boot up. Then I tried multiple versions and didn't work. I again installed pie beta using odin from xda. Then I was able to boot it up again. That's when reading online and xda I think but don't recall exactly where I got suggestion to use smart switch to downgrade to Oreo. I think it took me to att version Oreo as my imei is for att phone. Then I again downloaded u1 from xda and installed.
Hopefully I was clear in explaining what I did. I can try arl1 and install csc. I'm ok with user data loss as I don't really have many apps or data. But can I install csc for my current ark5 and see if that gives me ota for arl1? I'm assuming arl1 is latest Oreo for s9 plus u1.
Thanks for your help.

You should get the official unlocked pie update from Samsung once it's released. If you were to flash the g965u firnware with Sprint userdata, you would receive the pie official w/carrier bloat that is currently being pushed right now.

I believe when the CSC is changed, it must be pushed with the bootloader, AP and everything else when using ODIN. It still wouldn't hurt to push the ARL1 firmware w/CSC to it and wait to hear when the official unlocked pie is available via OTA to make sure you're able to get the OTA push. And yes, ARL1 is the unlocked U1 final Oreo fw.
Also, when you flashed to the pie beta, were you using the official z builds or the leaked "c" carrier builds? That might explain why you had issues flashing back

Personally, I would wait. The unlocked build will be pushed in the next day or two once the majority of the carriers have pushed it. The only benefit you would gain from going ahead and flashing it would be to get carrier specific features like WiFi calling, but that also comes with the carrier bloat. Most carrier specific apps can be had from the play store anyway.

It still wouldn't hurt to push the ARL1 firmware w/CSC to it and wait to hear when the official unlocked pie is available via OTA to make sure you're able to get the OTA push. And yes, ARL1 is the unlocked U1 final Oreo fw.
Also, when you flashed to the pie beta, were you using the official z builds or the leaked "c" carrier builds? That might explain why you had issues flashing back

First pie beta was ota. Second one I believe it is c but don't recall exactly. I will try flashing arl1 and will see how it goes. Any suggestions on where to get it?

Thank you for detailed explanation and questions.
My phone is originally att which will be u device. If you remember or heard of it, back in April we had att phones in Samsung site for 650$ and that's where I bought it. I was never on att Network so I submitted for unlock and meanwhile installed u1 from xda
then I unlocked and used tmobile sim. It always got ota as expected. In November I signed up for Samsung pie beta and then did an ota to pie.
When I wanted to revert back, I downloaded latest u1 and installed through odin it didn't boot up. Then I tried multiple versions and didn't work. I again installed pie beta using odin from xda. Then I was able to boot it up again. That's when reading online and xda I think but don't recall exactly where I got suggestion to use smart switch to downgrade to Oreo. I think it took me to att version Oreo as my imei is for att phone. Then I again downloaded u1 from xda and installed.
Hopefully I was clear in explaining what I did. I can try arl1 and install csc. I'm ok with user data loss as I don't really have many apps or data. But can I install csc for my current ark5 and see if that gives me ota for arl1? I'm assuming arl1 is latest Oreo for s9 plus u1.
Thanks for your help.

Hangoverr,
You maybe right about smart switch reverting you back to the u firmware based on your imei as it was originally a carrier device. From that point forward, if you flashed over to the u1 firmware and used CSC_Home to preserve userdata, that would explain the lack of OTA pushes as it's still tied to ATT/TMB CSC. Did you happen to flash home instead of csc when switching back over to u1 firmware?

I might have flashed home. I will look over xda for arl1. Would you mind giving me the link if you already have it?

Use the latest U1 file in that root folder of androidfilehost and use the patched odin mentioned in the original post to ignore the hash check. Remember if it fails to flash, hold power, volume down, and bixby until it resets into download mode again, Odin connects again, unplug, and replug the phone back in, once Odin confirms connection, flash.

Looking at your screenshot I think you might possibly be okay. Looks like you are on U1 ARK5 with a T-Mobile SIM? I have the exact same thing(except my phone was originally Verizon), and I was not getting the OTA for ARL1 either, so I Odin'd it. I later realized I don't think the OTA is even available for my phone configuration.... Check here on the phone info app, even though I am now on ARL1, the latest version is still showing as ARK5. I don't really understand how this all works, but also if you search U1 firmwares on SAMMOBILE labeled with product code TMO, it will also shown you ARK5 as the latest. If you select a different carrier in the drop-down menu, it will give ARL1 as the latest. I don't really understand how carriers are associated with U1 firmwares, but that is what I am seeing on SAMMOBILE.

The u1 firmware is still pushed OTA via your carrier. When you check for the latest update, your phone doesn't check Samsung's servers directly... Your phone queries your carrier. Whether your carrier is pushing Samsung's unlocked firmware updates or not is a different story. If your phone is saying you're up to date and you know that there is a more recent update, you will have to use smart switch or kies to directly contact Samsung's firmware servers, which may or may not be releasing to your time zone/region at that time.
Otherwise, you will have to wait for your carrier to push the OTA. Generally, carriers can release the unlocked firmware immediately as it doesn't require any additional modifications on their end before pushing it to Samsung's unlocked phones, but sometimes they get lazy or run into issues pushing it. After all, the carriers aren't making money off subsidizing unlocked phones, so why hurry to push firmware to them. Know what I mean?

Thanks for the explanation ? That explains the behavior I have seen, and I guess that's what those carrier designations mean on SAMMOBILE when I look for U1 firmwares. T-Mobile seems to be the slow one! I find it convenient enough just to Odin the ones that come out with XAA code.
For those who aren't already aware, N970U is the model number of all of the US carrier versions of the Note 10. The N970U1 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.
This is not a "beginner's guide to Odin flashing" type post/thread, so I won't list basic, step-by-step instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware, I recommend you consult one of the "beginner's" posts/threads - there are tons of them here on XDA.
Happy flashing!
U firmware: https://www.androidfilehost.com/?w=files&flid=297977
U1 firmware: https://www.androidfilehost.com/?w=files&flid=297978
NOTES:
- DON'T QUOTE THE OP WHEN YOU REPLY, kthx
- I have an identical thread for the Note 10+
- 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
- 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
- I know AFH servers/mirrors can be wonky sometimes, so if you want to download the latest version of whatever firmware you're seeking yourself, you can do so via SamFirm or Frija (plenty of links and threads here on XDA). I pay for a subscription to a site that gets beta builds and also gets the official releases (usually) before they hit SamFirm, so that's where my files come from. However, I don't have unlimited bandwidth on the site, and it's also 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 update 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 SamFirm.
- You can get USERDATAs from SamFirm for everything but AT&T and Cricket- those files will never be on SamFirm. So I'll try to always upload at least one USERDATA per bootloader increment for those carriers, and 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 USERDATAS (all the others are self explanatory):
AIO = Cricket
CCT = Xfinity Mobile (Comcast)
CHA - Spectrum Mobile (Charter)
TMK = Metro PCS
- 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
Firmware is now available via SamFirm and Frija, but manual entry is required in a lot more cases than previous models. Hopefully that's just because the phone technically doesn't release until Friday, and that they change that on Friday or soon after.
Manual entry is currently required for VZW, CHA, and TMB U firmware, and for all carriers/regions/CSCs of U1 firmware

I only saw the news about the Verizon models getting updated. Theoretically that means that Xfinity and Charter should also have updates, since they all get the same updates at the same time. Not sure about any other models yet

By the way, I did use manual entry in SamFirm to find TMB firmware and download it. As a rule of thumb, I usually don't flash my phones right away after getting it, as I want to make sure that it isn't defective

Cool, my PC is ready and setup for Note10 Any idea if XAA firmware and the carrier's firmware are within the range/build date to allowing flashing? As I know the downgrade usually fails.

You can't downgrade if there's only one software version that's been released so far - there's nothing to downgrade to.
But even if it's months or years down the road, the flash will only fail if you're trying to downgrade bootloaders. As long as you operate within the same bootloader, you can flash anything you want
This is the one I'm getting direct from Samsung: SM-N970UZSAXAA. It is supposed to be unlocked. I asked for a Sprint sim Card. I hope it's not tied to Sprint, but can be moved to any US Carrier if I want to once the TMB-SPR merger completes.
SamFirm shows this firmware for TMB: N970USQU1ASH4 and I checked U1(XAA) as well and they are the same

Looks like everything is back to normal, in SamFirm. Manual entry is now only required for VZW U firmware, as has traditionally been the case. Also, if you type in an older version for VZW, it will automatically give you the newest version, if there is one. So you don't have to always know the exact newest version - entering in the correct details of any previous version should always trigger the newest one.
Also, SH4 is now showing as the newest build for U1, T-Mobile, and Verizon. Spectrum gets SH5 (no idea why), and Sprint is still back on SGO.

Received my Note 10 U1, tested it on original firmware XAA(build: ASGO) and just now completed flashing to T-MO without updating to ASH4 build and want the phone to find and update firmware to see if OTA works. To get to download mode, I needed to press Vol + and - and power and the same time.
Flashed 5 files: BL, AP, CP, regular CSC and USERDATA. Device shows T-Mobile logo at boot, has Advanced Messaging, Video Call and I don't see any bloatware except for couple of T-Mo apps.
Went through setup and was able to get new OTA with August 1 patch(screenshot)
Wow great job! Can I get the link for the 10+ ...

You can go to my profile to find all of my threads. But flashing U probably won't give you wifi calling. It's been extensively discussed in my S10 threads, and it usually doesn't work if you have a U1 model

Initially, before I put in TMB sim, phone was on XAA/XAA/XAA. Now after all was said and done, my phone shows TMB/TMB/XAA. Make sure you put in the sim when you get the phone and when it has original firmware, so it can apply sim carrier's settings. Then you can flash and get the results that you need.

That's not much information.
1. What's the current U build?
2. Which U1 build are you trying to flash?
3. Where do you get that error exactly?
4. What Odin version are you using?
5. Do you get any other errors, either in Odin or on the phone itself?

Sorry, the phone was purchased as a unlocked version from samsung, model number SM-N970UZSAXAA/SM-970U1 is what the box says.
1. N970USQU1AHS4 is the build that I was able to flash. And the actual problem is that I had a brain fart and didn't read your simple instructions and instead of booting the phone first I opened the box and flashed the firmware. The issue I am having is my "Service provider SW ver. is stuck at XAA/XAA/XAA and I'm trying to get it to switch to VZW.
2. N970U1UEU1ASH4 I looked at all the n970u1 firmwares on samfirm and this was the only one that had XAA.
3. After I load the files into their locations and hit start it checks the files and the fails on the 4th step, I can run it again and find out exactly if you'd like.
4. 3.13.1 patched I believe.
5. None
I may be taking the wrong route to answer my problem. I really need help with getting it to show the right service provider code VZW.
Thank you for your help.
Hi XDA haven't been on here for a while.
So I have a question I was given a S9+ from Sprint it's unlocked I'm currently using it on TMO but I don't have wifi calling nor video calling. I wanted to see if it was possible to flash a TMO firmware. Since it's still on July's patch here's a screen shoot of current firmware.
I moved from Sprint to Tmo, and just put in the sim and then updated the firmware through the system update interface. All works as expected.
The difference may (or may not) be, if the phone was unlocked by Sprint or by another method. My wife's phone was unlocked via "another method" and cannot get it to update system software. I haven't bothered looking into it further though, as we don't expect to keep the S9+ too much longer.

if your phone is unlocked via whatever method, it wont interfere with system updates. OTAs will happen at regular intervals based on the firmware flashed on the phone and the recovery status. Stock recovery means that youll get OTAs, if youre not, its likely a glitch and has nothing to do with the unlock status.
If youre looking to get your phone working on tmob and its a spr phone, all you really need to do is unlock it, put the new sim in it and configure the APN. If you want full features like voLTE and wifi calling, then youll need to flash a tmob firmware version on your phone which requires the patched version of Odin. I have a Cricket branded (originally, at least) S9 and i flashed the U1 firmware on it via patched Odin and the phone now thinks its a factory unlocked S9, as i also unlocked it via "alternative methods". Perfectly seamless transition and i get OTAs all the time

Sorry to revive the post, so i finally did the update it worked flawless i did the update to the latest firmware G965USQS7DTB1_G965UOYN7DTB1_TMB now i got Wifi Calling and VoLTE.
I used Odin3-v3.13.1-Patched
Unrar the firmware and then just load the files in Odin
Heres a great tut https://www.youtube.com/watch?v=bnPkwICq_Bw&t=
Purchased a sim unlocked SM-T978U (Verizon Tab S7+ 5G) and am trying to flash the unlocked or Tmobile stock firmware to it. I've gotten "passed" flashes everything when flashing all of the files from the corresponding stock firmwares, but everything it boots back into the Verizon firmware. Any suggestions as to what I'm doing wrong that would cause this? I've probably flashed this thing 20 times at this point.
its a verizon tablet so thats normal.. u need to change csc is all
Thought that was part of flashing it with the patched version of Odin with a different CSC version of the firmware, but I've not done this before. Any suggestions or resources you can point to on how to do this? Thanks!

patched odin only removes hash checks.. all the firmware has multi csc (all the usa csc) so simply flashing firmware doesnt change csc
Gotcha, so change the CSC first, then flash the matching firmware? What's the best method for changing the CSC on the S7+? This process? https://www.**********.com/how-to-change-csc-in-samsung-galaxy-phones/
Any suggestions on how to change the CSC? I've hit a wall and haven't been able to find a way to change it and then flash the desired firmware.

You need to flash with odin, wipe, then pop the other carrier sim in, on reboot it will boot with that carrier sw.

Ok, so SIM out, Odin flash with the TMB firmware. Then, what do you mean "wipe?" Is that just choosing the CSC file in Odin so that it resets all data, or some step after to wipe it?
So I tried again with these steps and had the same result, back into the Verizon firmware.
Removed Tmobile Sim
Odin flash TMB firmware
Tablet reboots automatically into VZW firmware
Then booted into recovery mode and performed a factory reset and cache wipe
Reinserted Sim and reboot
Tablet still boots into VZW firmware
I also tried this same process but with the unlocked "USC" firmware with the same results.
Am I supposed to somehow prevent the first boot after odin flash to perform the factory reset? I've tried that unsuccessfully but maybe I have the timing off or something.

dunno wat ur flashing but all the firmware is the same.. theyre all multi csc.. so simply flashing different firmwares wont change csc lol
I don't know if this will help but on some samsung phones you can change the csc by opening the dailer and typing "*#272*IMEI number#"
edit: IMEI must me copied from the about tablet section in the settings. Press on the IMEI for a second and it will be copied to clipboard. Typing the IMEI will not likely not work.
After entering this in the dailer a menu pops up and you can select csc. Note this will usually factory reset the device.
Yes if you try this, please let me know if it works. I have the T878u 5g from Tmobile.
Any update on this? I purchased an SM-T978U (on Samsung website that is t-mobile S7+)
I expected it to not be carrier or network locked but it was locked to the t-mobile network.
Would love to flash an unlocked firmware but I can't find SM-T978U firmware, let alone U1 firmware...... I realize that flashing U1 firmware won't unlock the network but T-mobile support tells me the device can't possibly be truly carrier locked because the IMEI isn't even in their system. So I thought maybe the carrier lock is in their app tied to the system instead of the actual device??
Anyway has anyone found the firmware for these devices? Sammobile doesn't seem to list SM-T978 as a device
These devices don't have a dialer so entering the IMEI method mentioned above won't work unless there is a trick?
Guys, for cross flashing, you must factory reset from within the OS before you flash. the newer security measures will not allow the device to accept even a full flash if the device is activation locked to an account. that is likely why you are flashing and still getting the vzw stuff to come up.
@elliwigy , though the devices are all loaded with multiple csc's, and you can change them on demand (if you know how), that will not automatically load the carrier branded bloatware that comes with each firmware, and certain settings that may, or may not, be enabled or disabled by the carrier. An example being native video calling that the verizon firmware has and the unlocked firmware does not.
I almost always flash my Verizon devices with the U1 XAA unlocked software. Among other things, this lets me get security patches faster, as i get them when sammy releases them, not when vzw gets around to it. I say almost always because there are still a few devices, like my tab s6, that are vzw models with some minor hardware changes that prevent it. But in the case of my Tab S7+ and my Note20Ultra, they are both rocking U1 XAA firmware.

not sure y u tagged me lol.. i know hiw csc works.. in fact, in my last comment before this one you can see I clearly said just flashing firmware won't change the csc? seems like basically what you said but in a few words

Where is this U1 XAA firmware to download? Specifically for the SM-T978U?
RE: jmwfl2000 -I always untick the "Auto-Reboot" box when flashing new TWRP images to prevent stock recovery from being reapplied.After the first boot all should be well.

I'm pretty stumped like OP. Where are you finding U1 XAA for Tab S7+? Doesn't seem to turn up anywhere. Would definitely appreciate it if you could provide a link. Thanks.
I tried resetting before flashing and unchecked the auto-reboot but mine still returns to Tmobile. I just want the call and text on other devices feature.
Edit: I go the feature to work without flashing a new firmware but I am still looking for U1 XAA for the tab if anyone found it.

Purchased a sim unlocked SM-T978U (Verizon Tab S7+ 5G) and am trying to flash the unlocked or Tmobile stock firmware to it. I've gotten "passed" flashes everything when flashing all of the files from the corresponding stock firmwares, but everything it boots back into the Verizon firmware. Any suggestions as to what I'm doing wrong that would cause this? I've probably flashed this thing 20 times at this point.

I bought an unlocked Verizon Tab S7, probably same seller. Its brand new, stil has plastic on it. Are you wanting to unlock Tmobile 5G bands?
