[Samsung Galaxy Note 10+ Questions & Answers] dottat:
Having just completed this a couple minutes ago option 2 there was what finally did it for me. I followed the steps in the firmware thread. Basically flash the complete U1 firmware for unlocked and boot without the sim in. When it finishes booting insert the sim and wait for the message about it needing to reboot and allow that to happen. Then after it's back up put it back in download mode and flash the FULL tmobile firmware including the userdata contained (I used SH4). When it rebooted from that I had the tmobile splash etc and all is well again.

I had tried the CSC etc attempting to not wipe and never had any joy. Guess the lesson learned for next time is to let an unlocked phone boot and see the sim card before flashing a carrier specific firmware.... alas my first unlocked sammy...
[Samsung Galaxy Note 10+ Questions & Answers] Mr. Orange 645:
When your N975U1 is brand new, fresh out of the box, never been used. If you go through the setup without installing a SIM card. Then your CSC would be XAA/XAA/XAA. The first one indicates the current carrier, the second one is a sales code for carrier specific features, and the last one never changes. It's hardwire in to show the original version of the phone.

Now, as soon as you insert a carrier SIM card, it detects it, provisions for that carrier, and forces a reboot, wherein it installs the features necessary for activation on that carriers network.

In the instance of T-Mobile, it of course provisions for T-Mobiles supported bands, and adds WiFi calling and VoLTE (but no carrier bloat or apps). So then your CSC would become TMB/TMB/XAA. T-Mobile bands/T-Mobile specific features/unbranded device.

If you then switched that SIM to an ATT SIM, it would again provision, reboot, install. And the CSC would change to ATT/ATT/XAA.

All the XAA firmwares are identical. When you download the TMB version of U1 firmware, it just means that it pre-provisioned for TMB. No different than the regular U1 firmware and then sticking your T-Mobile SIM in it.
[Samsung Galaxy Note 10+ Questions & Answers] DeeXii:
So does that mean the point of a N975U1 which is labeled TMB is a firmware that has already been provisioned as you mention?

Is there a way to make it XAA / XAA / XAA again?

I notice that no matter what I do it never asks for a provision reboot.

Thanks for the info!!
[Samsung Galaxy Note 10+ Questions & Answers] Mr. Orange 645:
Yes, that's what I meant. It's XAA firmware that's already provisioned for TMB. But your phone will automatically provision for whatever SIM is in the phone. So you could flash ATT U1 firmware and it would just install as TMB.

And you used to be able to switch back to XAA/XAA/XAA with factory binary combination files, but that no longer works for carrier switching, as far as I know. It involved flashing the factory binary AP file, then flashing the CSC file from the Canadian firmware of all things. Then installing a CSC in settings, and then running some ADB command. If you look back at the old Note 8 carrier switching threads you'll see what I'm talking about.

How did you get it to work

How did you do it tried myself many time. Still cant get the splash screen or any tmobile features
[Samsung Galaxy Note 10+ Questions & Answers] dia_naji:
1.Take out sim card

2. Boot into download mode

3. Flash U1 firmwire with all 4 files. BL, AP, CP, CSC

4. Once it finishes it will boot up.

5. Go back into download mode and Flash U firmwire with the TMB USR DATA. ( If you don't flash the usr data you won't get the TMobile features and the splash screen.

Note: make sure to download the correct files
[Samsung Galaxy Note 10+ Questions & Answers] thekidd24:
Correct files?

I am using the ones from samfirm? is that not right. U1 XAA and U TMB
[Samsung Galaxy Note 10+ Questions & Answers] Shad0wsabr3:
My 1st venture into unlocked phones was last year, Samsung Galaxy Note 9. I ofcourse bought it outside of my carrier which is tmobile. I noticed that when I logged into my tmobile account my phone was listed as unrecognized device. I'm assuming that's due to it not being from tmobile. I never flashed tmobile firmware onto my note 9.

My question is, when I get my unlocked note 10+ and flash it with tmobile firmware, will my phone then be recognized on my tmobile account as a galaxy note 10+ or will it still come up as unrecognized?
[Samsung Galaxy Note 10+ Questions & Answers] BigMosley:
I believe it will only know what phone you have if you purchased it through them. My last phone the S10+ was Unlocked and I put the T-Mobile firmware on it and it never showed what the device was on the website.

Do u mind sharing how u confirm VoLTE works? Where is the setting to turn on VoLTE? Thanks.
[Samsung Galaxy Note 10+ Questions & Answers] Mr. Orange 645:
There is no setting. It's on by default.

Oh okay. But how can we confirm its working?
[Samsung Galaxy Note 10+ Questions & Answers] Mr. Orange 645:
As far as I know, the only way to test it is to make a phone call then try surfing the Internet. If you can use data and talk on the phone at the same time, VoLTE is working.

again many people don't have any issues with using the unlocked phone on tmo. it depends on your area and congestion of the tower you are on. these threads spread so much FUD on this subject. i see no decrease in speed over my previous note 9 and im in LA where it can get congested quickly on a tower you may be on...
[Samsung Galaxy Note 10+ Questions & Answers] PinkLapel:
Guys, I have an unlocked note 10 plus from Samsung, my girl has the same phone but bought from a tmobile store. We do not have an option to video call on either phone. Called tmobile and they had me on the phone with a Samsung tech guy, and he remote accessed my phone. He could not find any setting in my phone to enable video calling. Is video calling working for any of you? And do you even have the option to turn it on or off in the settings ?
[Samsung Galaxy Note 10+ Questions & Answers] pcriz:
Many people not having issues doesn't fix my issue.

I live in an area with no congestion and my device is running slower to the point where videos won't load at all where they used to. If you aren't having an issue, why try to stop people who are having issues from finding a possible solution? Just appreciate the fact that you aren't having the same problem?
[Samsung Galaxy Note 10+ Questions & Answers] Ace42:
You'll have to flash the T Mobile firmware. Video calling for TMO wasn't available for the unlocked S8-S10, nothing has changed.
[Samsung Galaxy Note 10+ Questions & Answers] Mr. Orange 645:
He said his girl bought her phone directly from a T-Mobile store and she doesn't have the option either. She should already have the T-Mobile firmware, as T-Mobile doesn't sell the unlocked version.

Of course he wouldn't have it, but she should.
[Samsung Galaxy Note 10+ Questions & Answers] dottat:
It's probably because the two contacts don't see each other as video call enabled (his being the weak link).

Did i single you out ? No I didnt, so why are you taking the post personally boss?

Ain’t no body trying to stop nothing partna. I’m posting to remind others who are also looking for general info on this phone that the unlocked works JUST FINE on tmo. For your info, ive 3 of these same devices on tmo here in LA and all 3 are as expect if not better. It’s unfortunate you and some others may be having issues, but its also equally important to state others have zero issues.

In my opinion , and to help you, if your phone is not working to your satisfaction, return it for a new device. Ive seen others flash the tmo firmware on this very same thread who had hands success. Did you attempt that? Seems the unlocked phone has the capabilities as the locked/ branded versions (same hardware, firmware, etc) so in theory your phone should work fine if you flash tmo software. If you choose not to and want to have a sub par experience, that is your choice.

You can have the last word on this boss if youd like. I wish you success nonetheless. :)
[Samsung Galaxy Note 10+ Questions & Answers] pcriz:
It's not about singling out.

You're trying to detract from an issue people appear to be having to I guess defend Samsung's honor? Really?

That's a great thought process. I need to justify my purchase so I chime in to reassure people everything is all good and there's nothing to see here. That's essentially what you said.

It's about users with no helpful input stating "a lot aren't having this issue don't worry about it" as if that's a magical fix.

You know what I do with posts I can provide zero useful input on when discussing an issue that I'm not having?

I don't comment.

Is that really that difficult?

Saying it's "equally important to state people aren't having the issue" is like coming into a hospital to remind folks that some people aren't sick, lol wut?

Not every issue is a call to recall relax and enjoy your device bud. There are plenty of threads about how awesome the phone is...

Correct, as hardware is different.
[Samsung Galaxy Note 10+ Questions & Answers] pcriz:
No, my understanding is you can't mix and match and expect to get updates. You would need to flash a build together.

[Samsung Galaxy Note 10+ Questions & Answers] Sumit42662:
The only difference is the phone processor between US model & global galaxy note 10+ & per best of my understanding rest of the hardware is same.

If i can flash the phone with global rom on TMO us version and replace the current sim tray with global version of sim tray, then there is a probability of both the physical sim to work as TMO phone doesn't comes with dual sim options.

TMO USA Model Number :- SM-N975U ( supports single sim)

Processor:- Snapdragon 855

Unlocked global Model Number :-SM-N975F/DS (Dual SIM) supports dual sim

Processor:- Exynos 9825

Won't work. You can go to the firmware threads now and see people who have flashed the wrong firmware (processor) and it failed. Can't flash that way at all.

Can't complain with my unlocked firmware. Lol
[Samsung Galaxy Note 10+ Questions & Answers] Mr. Orange 645:
This has been stated many times, and has been true for all the past Samsung phones.

You even said it. The processor is different. Doesn't matter how much of the rest of the phone is the same. It's different hardware. If you do manage to somehow flash the F/DS firmware on a T-Mobile device, you will the proud owner of a very expensive paperweight.

And NOTHING...and I mean NOTHING...is going to enable a second SIM slot on a T-Mobile device. For one, it's not there. For two, even if it was, there's no IMEI assigned to it. It would be useless.

This should attest to the hardware on the unlocked version in that its as good as the variant models. So would seem to suggest those who have issues its likely something local in their area or phone account.. ive got 3 note 10+s and they are all giving me great results on tmo...
[Samsung Galaxy Note 10+ Questions & Answers] pcriz:
I don't think it's ever been about hardware. It's been about whether or not the software is ultilizing the hardware the same across the builds.

All NA Note10s are exactly the same hardware.

So's I flashed tmobile firmware onto my unlocked snapdragon note 10 plus last night. I'm aware of a security update for September. I checked for updates by using wifi and carrier signal and I only get a message stating my software is up to date and it also shows that the security patch level is August 1st.

I was under the assumption that by flashing tmobile firmware onto unlocked phone you would be able to receive carrier OTA's.

Am I doing sumn wrong or was my assumption inaccurate?

[Samsung Galaxy Note 10+ Questions & Answers] DeeXii:
So enabling RCS is a bit trickier.

On the note 8 and note 9 ot would work properly with the process I described.

On the note 10 I had to flash the XAA firmware first with no sim in. I then used *#272*IMEI to change all CSC back to XAA. Then reboot. After you reboot insert sim and allow carrier provisioning. At this point you should then flash the TMB CSC file. It's kind of tricky on the last part. I've done it 3 times now.

You already have VoLTE. The only thing you're missing with the U1 Firmware is video calling, RCS text messaging, and a magenta boot screen animation.

Here's the one he'll want if he had an unlocked one before.

My question is this -

I have already spent a lot of time setting up Nova Launcher, custom widgets and icons, etc - will flashing the T-Mobile Firmware cause me to lose all this stuff? Or will it just change how some of the innards work?

---------- Post added at 01:30 PM ---------- Previous post was at 01:28 PM ----------

How do you know you have VoLTE? I don't see anything about it anywhere in the phone settings, and my calls don't have that crisp digital sound that they had on my Pixel 2XL that also used to show "HD Voice" on the screen during calls (my unlocked Note 10+ does not show that and I also wouldn't describe my calls as being "HD"). I do have Wifi calling already, though.
[Samsung Galaxy Note 10+ Questions & Answers] chowdarygm:
It will reset the full device, so better to take backup before doing anything
[Samsung Galaxy Note 10+ Questions & Answers] Mr. Orange 645:
Honestly not sure how to confirm it. I've been told if you make a call and can still use data on LTE, then you have VoLTE. My Note 8 ran the U1 firmware on T-Mo and I had VoLTE.

My Note 9 was running T-Mo firmware and you're right it did show "HD Calling" but honestly the quality of calls seems the same on my Note 10+ running the U1 firmware. At least according to my ear-o-meter it's the same.
[Samsung Galaxy Note 10+ Questions & Answers] cjxsutton:
I just flashed this to my device and noticed the T-Mobile magenta boot screen (could have done without that) and the arrival of the video calling dialer.

So I decided to go to Software Updates and check for updates and now it's saying my software version isn't supported and to visit a service center.

Any idea how to get it functioning as "supported" again aside from flashing the entire firmware? I'd like to keep the T-Mobile features as well as get OTA updates.

Just to clarify, the phone is functioning fine still - it's not bricked or anything. It's just now saying unsupported software when I go to software updates. I definitely want to still get updates.
[Samsung Galaxy Note 10+ Questions & Answers] chowdarygm:
Did you use 'Home_CSC' or 'CSC'?
[Samsung Galaxy Note 10+ Questions & Answers] cjxsutton:
I used the provided links that I quoted. There's only one file in there. I dropped it in the CSC section and flashed it.
[Samsung Galaxy Note 10+ Questions & Answers] chowdarygm:
I always used full firmware files to flash from unlocked to carrier instead of just the carrier specific file. Any flashing without reset usually causes some or the other issue
[Samsung Galaxy Note 10+ Questions & Answers] cjxsutton:
I was able to fix it by flashing the ENTIRE U1 firmware that I got from here: https://xdaforums.com/galaxy-note-10+/how-to/n975u-n975u1-firmware-links-t3957648

Don't have any of the T-Mobile stuff anymore, but at least I was able to undo what I did previously. Luckily I made a backup right before.
[Samsung Galaxy Note 10+ Questions & Answers] djelmonstruo:
My phone doesn't show the VOLTE signal only LTE+

Also when I'm in a call it shows LTE+ ...
[Samsung Galaxy Note 10+ Questions & Answers] chowdarygm:
If it shows LTE or LTE+ when you are on a call, it's means VoLTE is active. If it's not, LTE symbol jumps to H+ or 3G.
