Specifically the SM-N960UZPAXAA model that I'm looking at on eBay. I have clicked on numerous links that say it doesn't have both of these bands or only band 66.
The phone will be on the Metropcs mvno which uses T-Mobile.

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.

Thanks for the reply! I don't have much experience using Samsung devices and I heard you can't root the snapdragon models; so is it just a simple flashing of the firmware? If I don't run the firmware, will all the LTE bands still be available to me?

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.
3. As far as I know you will have all bands available to you, though some people have said they get better coverage and signal on T-Mo after flashing the actual T-Mo firmware.
I'm currently running the U1 firmware on an unlocked ATT Note 9 and using it on the T-Mobile network without any issues.

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.

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, does anybody know how to do a carrier switch with snapdragon like Samsung galaxy S8?
There is a how to in the S8 sub forum. Wonder if it is done the same way. Anybody tried?
Switch
Looks like it i got the verizon variant and ive downloaded the xaa rom which i believe is the candian one and it worked but didnt have any of the features like volte and wifi calling so i just now flashed att firmware and it worked flawlessy so yes it works!! no root no complications

We will need eng kernel before that happens. I'm sure it will be doable in the future, not now though.

So if I flash AT&T firmware on Tmobile Note 8, it should work fine on AT&T since there's no Tmobile Unlock App in it? Right?

Yes...if you look into the s8+ forum for carrier switch there is a guide that should also work for note 8...the main focus is to change the csc...however, you may just be able to flash the ATT firmware and it work when you put in the ATT SIM. It may be better to flash the unlocked firmware first...and then to att...but to get the device to be csc ATT, instead of ATT, ATT, TMB, You may have to follow the S8+ guide...
So try the easiest first, flash ATT...If activation does not work, flash Unlocked then ATT, if that is no good...follow the S8+ guide with Canadian firmware to change csc code of device to ATT...you might pm the op of the S8+ guide about what Canadian firmware to flash to change the csc...I am going to make a guide for us when I have a chance to test it myself...if just flashing to AT&T works...awesome, good luck
Oh yeah...the device must be unlocked first to change carriers...you can get it unlocked by T mobile or by paying for it
I'm located in the USA and AT&T is my carrier. I would like to be able to run custom ROMs on the phone. I did a quick search and came up with the following models "SM-N960F or SM-N960F/DS". Which version of the Note 9 is able to run custom ROMs? Thank you in advance for your advice.

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.

Based on this thread, it looks like the 960F DS has the correct bands to run on AT&T. It may be missing some features such as Wifi calling though.
https://forum.xda-developers.com/galaxy-note-9/help/sm-n960f-ds-att-t3846648
DS means dual sim. D is the single sim.
snapdragon also have the n9600 that is rootable.
only one dev right now so only 1 rom in xda.
might be more in the future...
forum is full of this info. brows around.
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.

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
From the t-mobile website: https://support.t-mobile.com/docs/DOC-39456

Unfortunately, I am not sure if you can flash the US Snapdragon firmware onto the Chinese model. In theory, it sounds possible.
I read on another forum that does have the technical talent that XDA has, that if I have an unlocked S10 with a U firmware and start on T-Mobile as an example and then restart the phone with an AT&T sim card that the phone will reconfigure itself for AT&T including the built in apps.
Is this true?
Thanks in advance.

Yes, Samsung uses multi-csc firmware on most devices for a few years now. If your going to use att for service though i would recommend flashing there specific firmware they release which is more optimized. There are a few threads with links to the files. And if you switch away from att later switch back to any other U/U1 carriers firmware.

NOT TRUE WITH THE S10 from a US CARRIER!!!
Each Firmware is Carrier specific if the phone is locked to that carrier!
Once the phone is unlocked, you CAN flash the USC Firmware, which is the Unlocked MultiCSC and AUTO SWITCHING for most USA carriers....
The only G973U phones that do this out of the box are the UNLCOKED phones from Samsung. They have a CSC of USC.
ALSO, good luck finding "AT&T Specific Firmware", as it is nearly impossible to find, the USC firmware hass all of the carriers bloat built in as well. and it switches it out automatically when you swap sims....
AND, if you do install the ATT specific firmware, you will just have to flash it again if you want to switch to another carrier and actually have their features and apps! SO, Just use USC firmware!

I was saying to use att firmware because its been agreed upon without it you wont have that good of signal. Blame ATT for being a**holes like that. Just because you CAN use other firmware dosent mean its the only or best way.
