According to this link, the T-mobile variant of the S10 only supports the necessary bands used for T-mobile, (B2(1900), B4(AWS), B5(850), B12(700), B66(AWS-3), B71(600MHz))
I know that T-mobile lets you unlock your phone under some conditions, so if I where to unlock it, would I get all the necessary bands used on other US carriers?
EDIT: Here's that link https://www.techwalls.com/samsung-galaxy-s10-model-number-sm-g973-differences/
That's SIM unlock, which is unrelated to activated bands. You'd need to access the service menu to see a list of all bands present. Although, one could flash the firmware of their desired carrier and gain access to features on previous generations.
Previous US models were able to access the required bands if the CSC and firmware were updated to the new carrier (I know from the S7 and S8. I cannot speak for the S10 though.

Im new to samsung, so do the locked bootloaders still allow to flash samsung signed firmware via odin?

Yes, that is correct.
Here is a link to the process for the S8+ just to give you an idea of what it will be like, but keep in mind, these are NOT the instructions you will follow, it's just for reference.

I've been thinking about buying a Chinese model, or any unlocked snapdragon model. Since they have the same chipset, do you think I could gain the necessary bands for a US carrier? For example, I dont think they support band 71 out of box. Im wondering if since they probably use the same modem, if it would be easy to somehow unlock those bands through firmware

Unfortunately, I am not sure if you can flash the US Snapdragon firmware onto the Chinese model. In theory, it sounds possible.

Hi Everyone -
AT&T finally gave me the unlock code for my Galaxy Note 3 SM-N900A phone. I'd like the move it to T-Mobile, but have some questions before I do:
1. Is there any way to flash the T-Mobile/N900T firmware to an AT&T N900A variant? I'm talking the official factory firmware...CSC, bootloader, radio, everything needed to essentially do a complete conversion. I'm not interested in custom ROMs based on T-Mobile's firmware and that kind of thing. I assume if there is a way, it's not as simple as flashing N900T firmware in ODIN, since it would probably fail the model checks.
2. Is there any way of enabling the 1700 MHz AWS band for HSPA+ on an N900A? I know it works fine on T-Mobile LTE and will also work on HSPA+ in areas where T-Mobile has refarmed it for 1,900 MHz. I assume the 1,700 MHz lockout on the AT&T version is probably a software limitation inside the modem firmware.
If anyone can shed some light on this, I'd appreciate it.
Thanks!

You can't flash them or you would get hard brick. If that were the case people would have already unlocked their BL's using T-Mobile

I wonder why it would hard brick though. With the exception of atts bl being locked, wouldn't it all be relatively the same? Would it be possible to clean up the n900T bl to match the n900a?

Make sure you pay attention to the Modificatinator file and add the T-Mobile carrier file after installation. Works fine and much better than stock ATT junk rom.
Quick question to everybody on here... Is it possible to ODIN the baseband/modem for N900A to the N900T? I want to do this because my service provider is Cricket, which is an MVNO of AT&T. It's not a priority, but is it possible?

Probably, and if it doesn't work you can Odin the stock NC2 or NL1 firmwware back and start again with this ROM.
But why? If you're getting LTE the way your phone is (assuming Cricket is giving you LTE), you won't gain anything by flashing a different modem. (Unless you're getting a lot less signal with this ROM than you were with the NC2 or NL1 modems.)
Hello, I'm a tmobile customer that just purchased an unlocked galaxy s8 from the Samsung website. I'm wondering if going to the store and getting the tmobile firmware on it installed is really necessary. I mainly want to do this because of the software updates, but then I thought the the unlocked version might get updates from a different source? Am I right? I'm sorry about this being such a general question, but I just want to do what's best for my new phone. Would you recommend me installing this firmware? Or should I just keep the stock unlocked firmware it came with? Are there any drawbacks associated with not installing the tmobile firmware on it?
EDIT:
To start, will Tmobile even do this in the first place? I'm totally clueless whether they offer installing their software on customer phones or not.
Thank you.
Hi there. Unfortunately, you are going to be really hard pressed to find a T-Mobile rep anywhere that could/would flash firmware w/ Odin. Not saying that there aren't some reps out their that don't know about this stuff (there are a lot that really have no clue though), but this is well outside of what most of them are trained for, plus Odin is only supposed to be used by Samsung. Also, historically (at least the last couple of years), for whatever reason Samsung's unlocked US models have been getting updates slower than the carrier versions, which really doesn't make any sense because there is less to go through to get them updated. That being said, there are several threads in the T-Mobile S8 forum here as well as the general S8 forum dedicated to carrier switching, which can guide you in turning your unlocked model into a T-Mobile model, for all intents and purposes.

The guy that replied first is really correct! T-Mobile store won't flash any phone, don't go beyond simple troubleshooting. It is easier to fly to Mars, than talk about flashing a device with rep. I do hope there are some T-Mobile reps that do really know about flashing, but I just haven't seen one yet.
I am with Unlocked S8 and use it on T-Mobile. I don't have any signal specific issues for example and features such as WiFi Calling, Band 12 and VoLTE all work well. There are few thing that flashing to T-Mobile firmware could give you:
Video calling(to specific phones only)
Advanced Messaging(believe other phone needs to support it)
DIGITS service will be built into the phone dialer.
I was also debating about doing it, but all 3 mentioned features are not wildly available and don't work across all devices and networks. On top of that you will get few T-Mobile apps pre-installed + Lookout app + T-Mobile logo when booting up the phone.
We can flash practically anytime we want, so I would suggest you to wait and see how Samsung will treat unlocked devices and how fast updates will arrive. If T-Mobile will do them much better than Samsung, then I will flash myself or when those 3 features above will work across all devices.
Sorry for reviving this thread, but my unlocked s8 gets slower upload and download speeds than my friends tmobile s8, we are both in NYC and he's getting 100mbps and I'm getting 30-40mbps. I assume they also have specific settings hardbaked in their rom that allows for optimized carrier usage?

the t mobile firmware comes with 4x4 MIMO and 256QAM. which leads to better signal and faster download speeds.
Can I flash just the modem or CSC to get the benefits without flashing the whole tmobile rom?

i think you'll need the whole firmware to be able to use RCS and the tmob features. i personally think the tmob firmware is better since it has 4x4 MIMO and 256QAM enabled. so better signal and service

I don't care about any of that. I value the Samsung unbranded experience more. All I want from the Tmo FW is RCS.
Alternately, if they ever support it using the unlocked S8 FW, i'll switch back to my S8 in a heartbeat. My G6 seems to get tons better battery life anyway for some reason.

I believe you have to use the "flashing unlocked firmware" because the prince's version of the ODIN will bypass the ROM checksum and let you flash any variant you want. if you use the normal ODIN and you are going from unlocked to t-mobile (950U1 to 950U) ROM it will fail.
I used to be on the unlocked but now I'm running t-mobile rom to have multi-line baked in to the native dialer. and my service provider SW ver. shows TMB/TMB/XAA
All is good and I'm happy with the ROM after few days the battery life seems the same as the unlocked version.
i just want to know if i can keep the bloatware free and just flash the modem from tmobile firmware.
i just want wifi calling, volte, 4x4 MIMO and 256QAM. i dont care much for the multi line feature cause not useful on my end and idk about rcs because the person on the other end needs to have it and i dont really see it as useful.
lol s7 bloatware free firmware was so easy to flash compared to this xD
im running the att variant but im sure all the hardware is the same. so i dont see why the unlocked firmware wouldnt support this out of the box.

When I had my S7 Edge I was able to mix and match different ROM with different modem files ie I would be on the unlocked ROM with the tmobile modem and was able to use the unlocked firmware with t-mobile radios. This is what you want but I have not tried it with the my S8 you can try if it dont work use the prince's ODIN to take you back to stock.

Correct, but it also works the other way around. Anytime you want to change variant you must use the modified version of ODIN as it bypass the checksum or the flash will fail.

Yes. All the N960U and N960U1 devices are the same exact hardware. They all support band 66 and 71. For the best coverage and support on Metro PCS, you'll need to either be running the U1 firmware or the T-Mobile firmware.

1. Correct, you can NOT root the US Snapdragon models.
2. Yes, you can flash any U or U1 firmware through ODIN without root or tripping Knox.

There are a few threads with instructions on how to flash to the U1 firmware from the U or W firmware. Flashing to the U1 or W firmware will not SIM unlock your device from the carrier it is locked to though. It is highly recommended that you SIM unlock your device first, if you plan on switching carriers. For example, T-Mobile uses an app that is included to unlock devices sold by them.

960F and 960F DS are exynos variant, with unlocked/unlockable bootloader, both should run custom firmware without problems.
The difference being one is dual sim (hence the ds in the name).
960U/960U1 are snapdragon variants and have a locked bootloader, so no go on those.
