I have an unlocked S9 (G960U1), and recently downgraded to the Verizon Rom G960U so I can get carrier features like wifi calling and Video Voice. Now I am planning on using another carrier, but I want to return to the unlocked firmware. Can I do this now? I read an older thread saying that it wasn't possible until Samsung came with a v2 bootloader version of their unlocked firmware.
omg someone please reply to above question im in the same boat
I recently flashed my oneplus 7 pro to the international firmware via a link on the page a few months ago when I paid off and unlocked my phone. I am buying a used S9 from someone that was purchased from T-Mobile. I'm assuming that it will also come with T-Mobiles own flavor of software?? If so, can I do the same thing I did to my OnePlus? Any links available to help would be appreciated.

yep, but youll need the patched version of Odin that doesnt trip the process up when the model # mismatch code is thrown up by Odin itself. The failsafe inside Odin is removed in the patched version allowing it to flash firmware for different devices without regard to errors that would otherwise prevent this. Kinda like firmware rape if you really think about it.

I bought a new AT&T Note 10+ from someone and then unlocked it. I have T-Mobile as carrier. I can use it with t-mobile for general use. But I am reading there are some features that wont work even with this generation of phones. Such as VoLTE and Video Chat and may be small other features . Also Voice mail default T-mobile app wont work either.
When I search I find many people have Flashed their phones with T-Mo firmware on Samsung unlocked devices. But i could not find any reference to T-Mo downloaded on a AT&T unlocked phone.
Any suggestions. If it is possible to wipe out AT&T from it and make it a T-Mobile operating system.
Thanks.
I have a At&t Note 10+5g and running latest update from T-mobile using Frija to find the latest firmware and Odin to flash the firmware to the phone.
Download manual samfrew.com or change csc

I am thinking about doing this. Just to confirm you have a galaxy note 10+ N975U from ATT and you're getting 5G through Tmobile on Band 71?
U might want check ur model numbers as n975u is not 5g.

It's wierd because T Mobile isn't mm wave 5G, it runs on Band 71 which e n975u supports. So I'm trying to figure out if it's possible to get 975u to do 5G on Band 71.

Thanks for the fast reply!
You'll need to flash the combination firmware and use Realterm to change the CSC from ATT to TMB, I think I saw instructions for multi csc device changing, should work for your device as well.

Try *#272*imei# to change your csc.

Tmobile uses a mix of mmwave and band n71.
And the band 71 thing is a bit more then that. They list it as band n71.. which (after reading on it) is not setup the same as band 71. Guess you can think of it like how wifi 6 works.
The n975u and n975u1 just don't have the hardware support for accessing/using band n71
I got frustrated searching for T-Mobile SM-N976U but just got AT&T unlocked SM-N976U. Thiniking of flashing T-Mobile firmware. Thank you OP for the forum, else I would have been stuck on AT&T firmware.

Please how did you get this done? I have the same AT&T Note 10+ 5G and I'm trying to install TMB firmware on it. Can you please guide me though how to do this or if there's a thread with instructions ?

**Phone gets wiped out**
I searched and found user @tyrone1 who listed the followings.
Phone still booted with AT&T logo..after skipping all stuffs..I wrote down my IMEI number.
used *#272*IMEI NUMBER# the screen gave me two choices
Sales code and Network Change or
Only Network Change
I chose Sales code & Network Change
Next screen I was able to select TMB.. ( It also showed different carrier)
Once I select that the phone restarted.. I popped my T-Mobile SIM in
The screen splashed with T-Mobile..
I check the video call and worked like a charm!!!
Good Luck..

First of all, you are a gentlemen and a scholar!! all this worked
AND i like to add the following to carrier unlock your phone.
the *#272# imei # thing does work to switch back and forth from att to tmo to att.
I got att locked phone and want it to work on tmobile. A lot on swappa going for MUCH cheaper than the tmobile phone!
went here to follow link to ask att for carrier unlock code
https://www.usmobile.com/blog/how-to-unlock-your-phone-from-any-carrier/
it says you'll get the unlock code in 24-48 hours. I got it in 15 seconds. well took me longer to log in and check status!
I flashed everything per @visualpro instructions. everyhting worked except the pop...i'm on tmobile. it said invalid sim. to me that said FU, i'm carrier locked and you on tmobile. so i did the *#272 thing went back to att. rebooted and it asked me for carrier unlock code. inserted carrier unlock code that i got instantly.
it unlocked and i did the *# thing and went back to tmobile and everything is all good to go!!
This was originally a att note 10+ 5g, as you can see it's now a TMobile unit!!
That's great it all worked out!!.. My mistake that I didn't specify mine that it was already unlocked AT&T phone. That was cool when you use *#272 imei and went back and unlocked it Credit goes to user @tyrone1 for that tip!
I was simply frustrated with higher T-Mobile prices on Swappa and after searching XDA many time, got the AT&T variant. On Samsung page it would show was Galaxy Note10+ 5G 256GB (AT&T) MODEL NUMBER: SM-N976UZKAATT.. but as long I'm getting fully T-mobile features, I'm all set

That's what I was saying too. On swappa they a premium for the tmobile version. Almost 100 bucks more. I got mine for 100 less than the cheapest tmobile one and it had 2 cases and a 512 SD card for 600 bucks. I saw the regular note 10 going for 690 lol.
Love xda!!!
Do I need to enter developer mode and enable USB debugging or anything before I do these steps with the 10 plus 5g? Also got the 10 plus non 5g can I do this to skip going to u1? Can I just flash from u att to u tmo and then do the IMEI trick or do I still need to go u1 first? Thanks
Can anyone confirm which 5G bands they have got working with this switch, also looking to bring AT&T SM-N976U over to T-Mobile.
Thanks.
Hey guys, so my question is how can I upgrade my Note 10 plus to Android 10, I have the SM-N975U model with ATT, i live outside the US so the person who sold me the phone unlocked it, the thing is that I was checking the original firmware for this model in Sammobile but alm versions are from different carriers (Verizon, Xfinity, etc) I didn't find the one for ATT. Does this make a difference? which firmware should I download?
Just follow this thread. You can use T-Mobile or Verizon firmware. All the same but Just use Home CSC for no data loss. You will not find the AT&T firmware using Frija or Sammobile (or anywhere unless someone extracts it & posts).
Check this thread out.

Hi mate. I don't know if it's gonna help, but I live in UK and I had 975U too which was on Android 9.
System didn't allowed me to update it, probably cause it was on AT&T so I followed a tutorial on yt and updated it to 975U1 Android 10.
EDIT:
N975U and N975U1 Firmware Links Here
For those who aren't already aware, N975U is the model number of all of the US carrier versions of the Note 10+. The N975U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100%...

I have Samsung Galaxy Note 10+ 5G from Verizon that I bought a year ago. It is fully unlocked and I changed my carrier to AT&T. However, I don't see wifi-calling feature anymore. So, I was wondering if I can flash it with AT&T firmware and get the wifi-calling feature back.
Model : SM-N976V ,
CSC : VZW
Can I flash with SM-N976U ? If so, can someone also point me to the download link for CSC:ATT ? I tried finding on sammobile but didn't find it (I see only T-mobile and TMK)
If the N976V is U4 or lower, short answer = possible, risky.
