Does the sm-n960U model have LTE bands 66 and 71?

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.

Is there a guide somewhere on how to flash U1 firmware on a carrier locked device?

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.

Thinking about buying the Note 9.

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.

So do the SM-N960F or SM-N960F/DS have all the correct bands for AT&T? Just curious as I have always wanted to do what you are doing...

Thank you for the information regarding the different versions of the Note9. I will go ahead and pickup the 960F DS.

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.

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.

Can i flash the sm-g977b firmware onto the sm-g977n device?

Hey 5G Pioneers,
I am wondering can I flash the sm-g 977b firmware onto the sm-g 977n device through the Odin? Did someone make it?
Since these two models are all using the same Exynos 9820 chips
And from my previous experience of using my galaxy s8, Samsung actually enabled me to flash the firmware in different regions only if the devices were using the same chip version.
I am currently in Australia. The Korean version of 977N is much cheaper, and it seems that is the only network unlock version that I could buy from the market.
Not sure where are you in Australia but I bought mine from a Telstra Sales Rep (based in CBD, Melbourne) where he got a discount code and gave its to me for AUD 1400 for the 512 GB Majestic Black Version, unlocked , I'm using Optus, VoLTE, VoWIFI works fine on it.

Thanks. Is this the exynos or Snapdragon version? I'm planning to buy the 256gb version and use in India. So wanted to check before I ask my sister to buy.

Hi everybody,
On Sammobile website, I found 4 firmware Korean variants. I tried getting more information on the "KOO" variant to see if its a stock Samsung firmware without Carrier Apps/Bloatware without luck. I couldn't get any detailed information whether it can be flashed over any other Korean variant. Can anyone here clarify if its possible and If yes provide further details?
Attached a snapshot.
Many thanks

That is the non bloatware Korean version but it doesn't allow me to flash it. I suspect you have to flash it with the userdata file also.
Thanks for the information,
I have a new phone so No issues with user data. How do I flash the firmware.
Thanks

Use all the files in the KOO firmware including the userdata.

Before I attempt this, Will this trigger knox? Void Warranty ? Will I be able to have OTA later on?

I have done it several times but it seems to fail. Nothing will be triggered.

Hi,
I have successfully flashed the "KOO" variant once with and a second time without "userdata", however that did NOT remove any of the Bloatware/Carrier Apps.
Any thoughts?
Thanks
I disable the 3 apps then hide them from the app drawer.

Hi,
I did disable the apps which is great, but there menu operator items as well!
Edit : Forgot to mention that the boot logo is of the operator as well.
I was researching something about using the PIT file along with the firmware but can't find the specific PIT file for S10 5g.
Use Odin or the modified version to flash combination firmware. Then flash your desired firmware.
This is the only way I am aware to remove all carrier bloatware and boot logos.
Dual SIM

I am particularly interested in this as the 977N variant seems to be dual sim. I notice it also has additional bands to the 977B varient and I would like to put the telstra firmware to ensure operation of VoLTE VoWiFi RCS etc.
The main purpose is to use at home and overseas. So more bands and access to features (VoLTE, VoWiFI, RCS etc. on my telstra SIM and local overseas SIM) when overseas are the goal.
Unless someone can confirm that the 977N with vanilla firmware will support all the telstra features?
Thank you for your assistance

5G problem of US variant in other country

I'm in US and want to buy a X1 ii now. But I do have some questions:
1. I know the US version does not support 5G. But is it the carrier issue or the US version lacks some hardware? If I use the US version in Hong Kong or Taiwan, will it work on 5G or should I flash some ROM to enable it? (in other words, are the hardwares all the same in different versions?)
2. The US version only has one SIM while I prefer a dual SIM version. So if I managed to get a HK version or EU version, can I use it in US without too much trouble? Will the other versions have 5G in US?
Thanks!
1. The US model is the same as the single SIM EU model. It works with 5G when flashed with the correct FW.
2. You can only use it with US carriers with US FW, since you need that to enable VoLTE provisioning on US carriers which will soon drop 3G in favor of VoLTE only. And US FW doesn't support dual SIM, though it can be flashed on a dual SIM model.

Thanks! According to your answer, if I'm going to stay in US for a while, a US version with US firmware is necessary to enjoy VoLTE (but never 5G in US). And I could flash it with, say Asian firmware, to use 5G in other regions than US. The dual SIM version, although not sold in US, can be used in the same way as mentioned here. Am I right?

Yes, though when running the US firmware it will ignore a second SIM.

How to convert note 9 korea to international version

I bought Korean samsung note 9.is there any way to convert frimware to international version
My model is SM-960N CAN I flash SM-960F frimware which is International version
No way to do that with official firmware. Some custom roms can force the N variant as dual sim though
Are you having issues with your N960N? As I have a N960N as my backup device and it functions flawlessly without any issue. I use it for a few months while I was repairing my N950N. Now I currently use it to back up my N950N as a backup device.

You could just install the stock Samsung N960N OS onto your device and that will remove all the bloatware. I personally have the LG U+ variant of the N950N, I just disable all the LG U+ bloatware and ignore the ones that I can't.

If you have the stock Samsung N960N OS installed onto your device and it is running smoothly. I don't see the point in installing the N960F OS onto it.
Please provide a screenshot of what you are trying to explain as I don't see those options on my N960N
