Sprint 960U unlocked on AT&T

I bought an unlocked S9 on eBay. Its a 960U model. Under Device Info the phone shows as being a Sprint phone.
Im confused about what to expect with this phone. My S7 unlocked came from Samsung directly and they handled updates.
With this phone, will updates come from Samsung? Do I need to be a Sprint subscriber to get the updates? Will I get AT&T updates?

No, you don't. If you want, you can flash it to the G960U Universal firmware. It doesn't have any app pre-install for carriers

At the end its up to the user.
G960U = Att bloatware, but features like visual voicemail, wifi calling, and other stuff .
G960U1 = no att bloatware, no att key features, but meh its up to you.

Thanks for the replies but I'm not sure I understood.
When security updates or firmware updates get released, typically you get them from your carrier or, if it's an unlocked model, from Samsung.
If I have an unlocked sprint device but I'm using it on att,will I get anu firmware updates at all?
Thanks

You will get it trough Samsung. Use Smart Switch on Windows to accelerate downloading the update.
See here the firmware release and timing from Samsung (no network) and from various providers, for your U there is no AT&T release:
https://www.sammobile.com/firmwares/galaxy-s9/SM-G960U/
Note that the firmware PDA and CSC are identical. Just release time is different and the add-on packages (that are not listed there).
For comparation, see the U1 firmwares:

I have an AT&T nash and I was wondering if it is possible for me to flash stock pie

I have an AT&T nash and I was wondering if it is possible for me to flash stock pie
There is no pie for nash xt1789-04 (att) but there is pie released for other z2 force. Will it break my phone if I flash pie stock over ATT stock rom? If so, can I have a link to the pie rom?

There's no stock 9.0 for any model. GSIs and custom ROMs are available, but an unlocked bootloader is required for either route. Users of the ATT & VZ models must wait for Moto to rollout Pie officially.
If you're interested in those things I'd strongly recommend selling your ATT Z2.

Oh, I thought pie was out because on gsmarena it says it's upgradeable. I guess it's wrong.
But when this does come out, for let's say, Sprint, is it possible for me to flash a sprint rom to my ATT MZ2F?

Moto released their update rollout. Among the phones slated to receive Pie you'll find the Z2 and Z2 Play.
Sure, you can try to flash the official build on your Z when it's out. Just keep in mind that the phone will probably lose LTE, and possibly other functions.

Ok thank you for answering

Normally, yes you can flash from a different model (i.e. Sprint FW on TMO model), with the exception of the AT&T/Verizon variants, which are bootloader locked, and you cannot flash anything (not even official firmware) on them.

That's wrong because I was able to flash android 8.0 att over 7.1.1 because it wouldn't let me update normally. I'm pretty sure you can flash images with the same stock signature, but I'm asking if it's possible to flash stock firmware from another model on to att phone with bootloader locked

Maybe I wasn't clear enough, I meant official firmware of a different model.

*NOTE* This firmware is free of all carrier bloat, but will also cause you to lose some features, depending on your carrier.
TMO - Advanced Messaging and Video Calling
SPR - Unknown
ATT - VoLTE, WiFi Calling, Advanced Messaging
VZW - Unknown - used to be WiFi Calling, but it has been reported to work on the S10+

Downloads Moved to Post #2​The Samsung Galaxy S10 series of devices with Snapdragon chipsets are universally compatible with each other's firmware, and can be swapped between Carrier-branded and US unbranded. This thread is for the S10+ and you will find firmware links in the next post.​
Before downloading, please read some important notes:​
You must use a modified version of Odin to flash these firmwares
You can update to a newer build of the same carrier firmware and keep your data intact if you use the CSC HOME
You must be SIM unlocked if you are trying to use a SIM from a different carrier than you purchased the device from
Flashing the U1 Unbranded firmware will remove carrier bloat, but it will NOT affect SIM lock status
In order to convert between U and U1 firmware, you MUST factory reset and leave your SIM card in the device after flashing in order for the conversion to be successful

Sorry I'm a little new to Samsung firmware flashing. But I have an unlocked Snapdragon S10+ that I'm using on T-Mobile would I be able to flash this update and then been on the T-Mobile variant firmware or will I need to flash something different as this is a small update?
Looking to get all the benefits I can from T-Mobile firmware like advanced messaging that I heard the T-Mobile variants get.
Thank you!

You have an S10+ directly from Samsung? Yes, you can flash the T-Mobile firmware and will essentially have a TMO device. You will need to wipe your data in order to convert properly from U1 to U firmware.

Does the T-Mobile Firmware include all of the T-Mobile bloatware apps?

Any non-U1 firmware will have the carrier bloat. Your SIM card determines what gets installed.

Added the U1 Unbranded firmware in Post #1

Can you flash the U1 unbranded firmware on a Verizon phone or do you need a U1 firmware for Verizon to remove all the carrier bloatware and restrictions?

U1 can be flashed on all Snapdragon S10+ single SIM models. You will have to factory reset after flashing in order to convert properly.

I have a verizon SM-G975U. It's unlocked and I use a TMobile sim. Can I simply flash the TMB firmware using odin on the verizon s10+ and it will be branded as Tmobile?
I contacted Samsung and they have not released the BYOD update yet like they have with my S9+, where the firmware automatically updates with whatever sim card is in the phone.

Not sure what BYOD update you're referring to. You can flash the U1 firmware and have a phone working on T-Mobile, but without Advanced Messaging and Video Calling from the dialer. Or you can flash the TMO firmware and have all features supported, including the light bloatware included.

When I change sim cards from one carrier to another carrier, it automatically changes the firmware. It does it on my S9+. Example: I have a verizon sim in my S9+, everything is all verizon, bloatware, startup screen etc. If I put my Tmobile sim in, it changes everything to tmobile, splash screen and all tmobile bloatware and verizon is removed. After looking to see why it does this, it's an update from Samsung that they put out called BYOD (bring your own device.) Only available for s8 and s9 models right now.
https://www.samsung.com/us/support/answer/ANS00078492/
I thought it would have done it on the S10+ but it's not available yet.

Hmm. I'd be surprised if the S10 series don't already support it, and the rep you spoke to was confused. The S8 and Note 9 did it fresh out of the box, verified personally by me when I switched both of my TMO devices to VZW for updates not yet available to TMO.

Nope, it doesn't support it yet. I wish it did but I guess I'll just flash the firmware to TMobile's.

I have a question if you don't mind. I just flashed my S10 Plus unlocked U1 version to the AT&T variant of the U version firmware. Right now I am on G975USQU1ASAT. I believe the G975UQU1ASBA is the newest update. I don't see the update on my phone via OTA though. Is it just slower for AT&T or I will need to flash it manually using Odin for all updates going forward?

Do you have VoLTE and WiFi Calling available? If you do not, then AT&T isn't recognizing your IMEI and won't push the OTAs to you.

Yes I can use VoLTE and WiFi calling after flash from U1 to U. This is actually the main reason why I did the flash. I am a bit concerned about no OTA update yet though.

OPX is a retail variant, so it's possible someone flashed a retail fw to get rid of bloat. Look by your charger port on your phone to confirm that you have an -04 (TMO) variant. If so, then search for "How to return to Stock" and you'll find everything you need to flash stock TMO fw. If you have anything else besides -04 then reply back with what you have.
As for installing lineage, as long as your device is bootloader unlocked, you should be able to get it sorted and install lineage.

Yes its -04 variant. now its confirmed that its tmo variant can i go further to upgrade it to PPX version? because i found out that there is a pie update for this firmware which is "NASH_RETAIL_9.0_PPX29.159-24_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml".
also as you said someone flashed a retail fw in my device so i can consider that bootloader of my device is unlocked, right?

There is no pie firmware for the TMO variant. If you flash any pie firmware you can kiss your baseband goodbye and enjoy your calculator. I don't know for fact that someone flashed a retail fw, I just know that TMO fw is OCX. To see if your bootloader is unlocked, reboot to bootloader and look. You should see flashing_unlocked if it is.

Well to be fair, I did install pie retail on my tmo and, after God only remembers how, I managed to comeback to life with imei and wifi. But yeah, I don't reccomand anyone to flash pie stock, unless I really hate that person ???

Can you flash US firmware on Korean or Chinese s20?

I ordered a Korean S20 ultra (988N), but live in the US. Has anyone flashed the US firmware on a bootloader unlocked SD variant of the phone (ie 988U1 firmware on a 988N or 9880)? If so, did you have to change the CSC to XAA before or after you flashed the firmware?

I don't have an answer to your question but will the non-US phone work in the US like on Verizon system as is?

It should work fine on LTE. The main Verizon bands are 2, 4, 5, 13, all of which are supported in all s20 variants. I don't think you'll get 5g on any US carriers, so if that's important, better to pick up a US spec phone, and pay to unlock the bootloader.

I tested the phone (G988N) on both Verizon on TMobile. I was able to get 5G on both carriers. So I can confirm that all features (except possibly WiFi calling on Tmobile), work.
So using the KOO firmware in the US works perfectly fine. No reason to try to flash XAA.
