Just posting here to provide information on how to get video calling working on a Note 10+ running on MetroPCS. I am currently running N975U1UEU3CTE7 fw.
The goal is to download the fw for your model(in my case XAA (unlocked varient)) that matches the csc file from the T-Mobile fw(TMB) with the same baseband (TE7). You need to have the patched version of Odin (IMPORTANT). Plug in all of the files from your model in there prospective slots in Odin, all except for the csc file which will be replaced with the HOME CSC file from the TMB firmware. If you would like to keep your phone the way it is use the HOME CSC file, or if you would like your phone to be reset to factory use regular CSC file. Make sure that your phone is attached directly to your pc (not into any kind of hub) and put your phone into download mode. DOUBLE CHECK to make sure you do indeed have the correct firmware downloaded (N975U1 fw for Unlocked Varient and N975U fw for T-Mobile). If all is correct you may flash away.
Below are screenshots of video calling operational on my phone.

I'M NOT RESPONSIBLE FOR ANY DAMAGE CAUSED TO YOU DEVICE!
THIS IS THE PATH I TOOK.
I'll pass on to you what I did. I flashed over SPR unlocked.
1. Download frija, you can Google this. It's a neat tool to quickly download firmware.
Type in the model number of your phone, and add a 1 at the end... Example... I own the N975U, from Sprint. Add the 1 at the end for unlocked... N975U1. And in the CSC slot, type XAA.
XAA is unlocked CSC code for US.
Firmware should show last digits BSLD for January security patch and Android 10.
Unzip the downloaded firmware somewhere close. I did mine on the desktop.
2. Download Samsung Drivers and install.
3. Download Odin V3 V 3.13.1_3B Patched.
Add the files into Odin.
On the CSC, do NOT use Home CSC. Use the regular.
You absolutely have to factory reset your device when switching to Unlocked or vice versa. So you might want to backup using Samsung smart switch or Google. Which ever you prefer.
Do not add any user data when switching from carrier to unlocked.
4. Place phone into Download mode BEFOR plugging into computer.
5. At this point... Phone should be in download mode. 4 files should be added into Odin. No other changes in Odin should be made. And CSC should be regular and not Home CSC.
6. Plug phone into computer and see if you see the device in Odin.
If you see it, great. Proceed to flash.
Odin likes to verify for awhile so don't mind this. Leave it be. If it gets stuck more than 10 minutes saying verifying, you may need to Google the issue.
Once Odin says passed... You should be good to go.
Phone will reboot, phone will factory reset.
At this point, you should be done.

You mention the CSC should be XAA, when it comes to ODIN you mention regular?
Can you clarify that part?

In addition, do I have to backup the contents (no user data on it currently)?

It's two different things that's being referred too. When you download the firmware there isn't just one and they are identified by CSC. TMB is for T-Mobile, CHA is Spectrum Mobile, SPR is Sprint.. to name a few.
In your particular case when you download the unlocked firmware you would search for the CSC "XAA" (without quotes) as this is the firmware from the unlocked note 10+
Second when you flash the firmware you need to place different files into the appropriate and applicable locations within Odin. One of those spots you place a file into is called "CSC".
Also no you don't need to backup anything if you don't have anything installed (or no userdata on it).
If you have further questions I would suggest you search this forum and/or Google. The question on flashing the N975U1 firmware onto the N975U has been asked before and covered in detail already more then once... So those other threads will be of help for you.
Hey all,
I am trying to flash the Tmo firmware onto my unlocked Ultra to get things like the video call option in the dialer, and for the life of me I am getting lost.
I used both Frija and SamFirm to downlad what it said was the correct firmware (SM-G988U1_1_20200312212815_gne8hvb170_fac.zip) putting TMB in the CSC. I flashed that firmware using Odin,
Here is what I did:
Downloaded the firmware (SM-G988U1_1_20200312212815_gne8hvb170_fac.zip) in Frija putting TMB in the CSC box
Unzipped all the files
Flashed them all to the phone in Odin, using HOME_CSC_OMC_OYM_G988U1OYM1ATCH_CL18186338_QB29814488_REV00_user_low_ship_MULTI_CERT.tar.md5 so as not to wipe my data
There is no error, and it finishes successfully, the phone reboots, and there is no change whatsoever.
Am I missing a step here guys?
Thanks so much.
**EDIT**
I finally figured it out.
I needed to flash the TMB U firmware, not the U1 firmware.
Curious do you notice better signal strength on TMO U firmware vs unlocked U1?
I have an unlocked, not rooted and factory OS Verizon(SM-G988U) with Android 10. I recently switched to T-mobile and was thinking to flash the firmware from Verizon to Tmobile to better use their wifi calling and other features.
Where can I get the latest files to flash the firmware? Also, to switch from Verizon to Tmobile, do I have to flash Verizon-->Unlocked(U1)-->Tmobile or can I do Verizon directly to Tmobile firmware? I read few threads but I was confused on what exactly I need to do.
I downloaded Odin v3.14.1 and latest Samsung drivers. Beside the firmware files and placing appropriate folders in BL, AP, CP and CSC, anything else I need to do?
Sorry for noob question but this is my first flash and was looking for exact steps.
Thank You
You need to go Verizon-unlocked-Tmobile. You'll want the patched Odin too. I use Frija to get my firmwares https://forum.xda-developers.com/t/tool-frija-samsung-firmware-downloader-checker.3910584/ but you can use sammobile as well.
Thank You. Is Frija 1.4.3 the latest version?
Also, the Odin I downloaded, the executable says "Odin3 v3.14.1_3B_PatcheD" which I suppose is latest and patched, right?
In the Frija, CSC, I got the Tmobile firmware as TMB. What is the code for the unlocked firmware so I can download it?
Also, do I need to root to flash the firmware from Verizon-->unlocked-->Tmob?
Noyou do not need root
In the Frija, CSC, I got the Tmobile firmware as TMB. What is the code for the unlocked firmware so I can download it?
Never mind found out.
SM-G988U1 , CSC- XAA for Unlocked
and
SM-G988U, CSC- TMOB for Tmobile.
Were you ever able to get WiFi calling to work?
I just got a galaxy s10+ from a friend who was on Tmoblie so it has the Tmoblie loading screen and apps. I would like to revert it back to the firmware CSC code XAA so I dont have to have the Tmoblie boot screen and apps. He didn't buy it from tmoblie its from an insurance company so I am pretty sure its unlocked. The app "Phone Info" says that Firmware's CSC code is XAA and the active one is TMB. I have tried to put in the *#272*IMEI# code into the phone but it just gives me an error code.
Is there anyway to revert it back to XAA without flashing the phone? Will I void the warranty if i flash the phone with official firmware? Also if I have to flash the phone where do I find XAA firmware as I only saw carrier firmware on SamMoblie.
Thanks for any help and very sorry if this has been posted a thousand times!
Also the phone model is SM-N975U / Galaxy Note10+
Device Type: d2q
Product Name: d2qsq
Bootloader Version: N975USQS6FUF1
CSC Version: N975UOYN6FUF1
Phone is on Android 11
I just flashed the phone and it all worked out. I used these threads to figure out the solution if anyone else is ever interested in how I solved this problem.
Note 10+ N975U carrier universal and unlocked models firmware.
Yep. I'm going to download the files just in case ,but wait a few days to see if anything happens.I'm curious if that was your issue all this time .

Odin Files/Guides For S21
Flashing S21 Ultra t-mobile branded to unlocked? Hi Everyone, I am a new samsung owner. I recently got s21 ultra t-mobile branded. It is now network unlocked. But i wanted to have a clean bloat free phone so wanted to have unlocked firmware. As i understand it, i need XAA G998-UA firmware...
forums.androidcentral.com
And I used this very kind user on Androidcentrals help. The context of my question is not needed but I basically asked if I was choosing the correct files.
"Yes use the firmware from frija , you will also need prince comsey patched Odin which download from XDA website, this will factory reset your device for first time , choose XAA as region with model number from unlocked version. (He is refering to the model number SM-N975U1) Put the device in download mode and make sure using a good cable and try 7zip to extract the firmware,odin,frija ...then after extract the the firmware you going take for files Cp/CSC,Bl,Ap and put in corresponding slots in odin and flash"
I would appreciate if anyone can point me to the right direction. I have 21FE G990U2 from AT&T, It is unlocked by AT&T.
All I need is working T-Mobile firmware or Samsung (no carrier branding) to flash. I tried multiple versions of U, U1 and U3 firmwares (all matching my current Binary -4) but no success.
I just would like to get rid of ATT bloat. I know I can uninstall it via ADB but I rather have firmware clean of it.
Any suggestion please?
Thanks
So am I right to assume that you are looking for a G990U2 TMB firmware with Binary 4, to flash on a G990U2 AT&T phone?
If so, then you can download it from the below link by clicking on "Download Samfw server" (G990U2OYN4EWC3, April 2023 update):
Download Galaxy S21 FE 5G SM-G990U2 (TMB) G990U2SQS4EWC3 in Samfw - Samsung firmware download

or if I am assuming wrong, can you please correct my understanding? As I do not have any practical hands-on experience with the USA models.

You are correct - I need T-Mobile (or carrier free) so I can utilize full carrier settings.
Thanks for the link, however above link gives an error when opening the page.
Nevertheless I will look for TMB firmware with CSC: G990U2OYN4EWC3 and post an update here
Flashed that and still has AT&T boot logo and all the apps

Well, I am sure that you have flashed by a Factory reset (Flashed CSC, not Home CSC in ODIN). The boot logo can be changed by rooting your device, also bloatware apps can be deleted via ADB command without rooting.. but you already have mentioned that you prefer not to proceed with those processes. So I am out of suggestions, sorry.
Just for my knowledge, after flashing the TMB firmware, now your settings> About phone> software information> service provider software version: 2nd line shows as TMB/ TMB/ AT&T?
(Also corrected the download link in my previous comment anyway).
Yes, you are correct i did flash CSC, not home CSC. Then I reflashed w home CSC but software still says ATT/ATT/ATT.
Moreover on Bootloader screen says "carrier ATT" - I have never seen that before on any Samsung phone that I had. I have no clue how did they lock up device that well. As for removing software via ADB that is not a problem, but ATT locks network selection mode so you cant choose between 5G, LTE, 3G etc..
TMobile in US still supports EDGE and sometimes it comes handy - whereas ATT has only LTE and 5G as they re-farmed EDGE and 3G/HSPA frequencies

I do not get why the CSC can never be changed, even after flashing the complete firmware... must be an ATT thing!
Anyway, to change the csc only, there is another very quick & easy method. It takes only 2/3 minutes; no flash or factory reset is required. You have to download and install a small software "SamFW Tool" on your pc/laptop (may need to disable the antivirus during the download/install process). Once done, connect the phone and enable USB debugging mode. Open the software, under the ADB tab, click Change CSC, from the dropdown list select TMB and click Change. The phone will restart and CSC "Should" change to TMB/TMB/ATT.
Here is the download link for the software:

That did the trick. I have T-Mobile CSC now
Thanks a lot

Great!
But still, that's only one part of the final solution I think. Your target was to replace the complete firmware from ATT to TMB, right? Since the CSC is now changed to TMB, I think you can give it another try via ODIN to install the TMB firmware now (only if you want). I am not confident that it will work now, but still, one last try should not be much of a hassle.
I think that these multi CSC contain all US carrier customizations....When I changed it to TMB it shows TMB/TMB/ATT and loads bootlogo as well as TMobile apps... I guess it is similar as Blackberry used to be back in the days...Depending which carrier SIM used it loaded proper settings from the firmware...
I have flash my METROPCS G990U2 to G990U3,other sim card work fine,but t mobile sim card does not work ,can someone help me?I already change CSC to xxa,but still no internet,I do have sginal bar
