I bought a SMN960U1 phone but ended up getting an unlocked ATT phone. Is there a way to flash it with Odin to get band 71 and 12?
I have read a bunch of posts and more confused than when I started. If you have a link to the correct version of Odin and ROM to flash I would be so grateful. I will keep looking through the posts in the mean time and will post back and answer my own question if I find an answer that works.
*update
Found post with wrong model number. It is missing the 9.

Would love to hear from anyone who has done the flash and if they get band 71.
It already has band 71 and band 12. It's supported natively by the hardware.

hmmm so you are saying the AT&T version has band 71 and I don't need to flash?

AT&T does not have Band 71:

But,if you are roaming on the networks that have Band 71 (T-Mobile & presumably the MVNOs that use T-Mobile's network),you should be able to use it w/o doing a thing.

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

Figured.

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.)
I recently made the mistake of ordering a Nexus 6 not knowing there were 2 versions. Now Im not able to use the LTE 28 band for use on the country I live. I bought the XT1103 that is the US version. So I was wondering if its posible to install the Lollipop 5.1.1 firmware LMY48I shamu on the XT1103. Will this enable the bands that are on the XT1100?
My XT1103 currently has the LYZ28J firmware

Yes, you can install it. But it will not help you. The only way for you to get b28, is to sell your XT1103 and buy an XT1100.

Not 100% true, there are a few threads around about enabling other bands on the N6.

a few certain bands is possible, band 28 i dont think is possible.
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.
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?
What do you mean by CSC?

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
From the t-mobile website: https://support.t-mobile.com/docs/DOC-39456
4G LTE
2, 4, 5, 12, 66, 71, LTE-U/LAA 46
Roaming Bands

Unfortunately, I am not sure if you can flash the US Snapdragon firmware onto the Chinese model. In theory, it sounds possible.
Hi! 4G isnt working on my Mi9 with A1 network but they use the suported frequencies. I tried reseting APN and some other changes in developer options nothing worked. Any idea?
I'm gona try and flash the ROM when I unlock it from CN to global or EEA. which one should I chose if there is any big difference?

Which variant do you have? if it's the alita / explorer / transparent edition (8/256GB or 12/256GB) then there's NO BAND 20, which is LTE for many providers. Have you checked this?
EDIT: see here, perhaps you're in an area that doesn't use band 7 and only band 20? If this is the case... No ROM you flash can alter that, it's hardware related. ONLY global devices (64/128GB) support band 20

I have transparet ediotion 8/256gb. Checked there is no band 20 in my area but 4g works everywhere else
Should I still flash the ROM to global or eea? Can I relock it after or is it gona brick..

Do not relock bootloader after flashing rom, it will most likely brick your device. Flash another ROM if you like but you won't get band 20
May I ask, why do you want to relock bootloader after flashing a new ROM?
