N976B firmware question

Hey guys...I have a Note 10 plus 5G from UK, but I am using it in another country (Romania). We have 5G here as well, so this is not the problem. The firmware on the phone is not the latest, but it doesnt find the new one via OTA. I checked the firmware site and there are the August one there. So the question is, if I upgrade via Odin, with one of those FW, will it lock to an UK carrier? Or a German one, or other? Or will it remain unlocked and no issues there?
Thanks!

If the phone is unlocked. The firmware you install on it will not lock it..

Indeed, thank you, did that, all went fine.

I have a similar question. I have a EE unit note 10+ 5g and was wondering if flashing the UK non ee version with a different CSC from samobile will actually change my phone's CSC or will it still detect it's a ee device and still say EVR/EVR/EVR under service provider information. thanks

If you use the multi-csc OXM it will change as per below.

Firmware Verizon VZW to unlocked version XAA ?

Hello,
I just bought the note 10+ N750U from verizon under the firmware N975USQU1ASH4 (VZW)
I do not have a Verizon Sim card but Orange (French operator), so I would like to put the phone with an unlock version (XAA?)
Is it possible ?
Or a more suitable firmware for France (even if the processor is an exynos in France and here a snapdragon)
How to do it please?
thank you very much in advance

If you just bought it. You may be in a difficult situation. Verizon does a sim card lock for 60 days. You have to use it under Verizon's network for the 1st 60 days.

No, I haven't received it yet but it's a second-hand model that has more than 60 days so a priori no problem there

It's possible ?

If your phone is already Carrier/Verizon Unlocked, then you can Flash the Unlocked Firmware.

Need to install T-mobile software on AT&T Unlocked Note 10+.

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.

No I have a Galaxy Note 10 5g model number SM-N976U and I am running latest T-mobile firmware feb.security patch ATA6 and still have 5g dont know which band but 5g is definitely there and yes it's an AT&T carrier locked phone.

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 ?

So what I did chronologically is:

**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.

SM-G9880 Flashing Question

I recently just bought a S20 Ultra that has a unlockable bootloader. A little while back, I had a Galaxy S9 that I could completely convert the entire device to U1. Is that even possible with this device ? To fully convert the CSC and bootloader ect, to a US model ?

That was then. Each model is specific to a region and can not be flash with software from another region. I.E you cannot flash G9880 with firmware from G988U or G988U1 or the other way around.

What exactly changed from the S9 to the S20 that made that impossible ?

Any luck? I just got one in Canada and it only has 3g ad 4g so I was hoping I could flash a csc file.

So I attempted to edit the band config using QPST and QXDM, but I'm very unfamiliar with both programs and how to actually read and write information to the modem using those programs. Definitely not for the average user. Back in the days when devices had ESN numbers, I used to flash software using QPST and QXDM but there is a lot that has changed with those programs, and I wouldn't even know how to do that stuff today. If anyone has any knowledge about those two programs that can help me unlock all the US 5G bands for AT&T and Verizon that would extremely helpful.
