Hey all,
I've done some rooting in the past, so have knowledge but it's limited comparatively to the community. I bought an Unlocked Snapdragon S9+ from Best Buy and the AT&T FirstNet service for first responders only works for AT&T branded devices. I wanted to try and flash an AT&T image on the phone if possible. Is this possible? Can anyone offer some guidance on how to accomplish this?

My S9 plus just did the carrier firmware when I put the Sim card into it. I didn't have to do anything else

I don't know what you mean by "did the carrier firmware". I'm looking to wipe and re-flash AT&T firmware on my device - it currently has an AT&T SIM card in it.

Yep, you can flash the AT&t firmware onto your unlocked device. You would have to download the firmware and then flash it with Odin, you can check the general section to learn more about this and we here can help you through it.
The other thing I was wondering is that I assume that FirstNet works on the AT&t firmware. Technically your phone will still not be an AT&t phone according to its IMEI number, but firmware-wise it will be just as an AT&t phone after you flash it.

I understand. So get ODIN and the AT&T firmware and just flash? I've done rooting before so familiar with ODIN for the most part, just wasn't sure if I needed a specific firmware version based on having an Unlocked device or not.
And to your wondering thought, FirstNet does work on the AT&T firmware and they WOULD still recognize my phone as an Unlocked device(by IMEI) as per the FirstNet tech support agent I just spoke with. However, I'm hoping that having the firmware would make the device more compatible with the FirstNet service

You just need the latest AT&T firmware that you can find(BRK2 I believe, unless the latest pie firmware has already been posted somewhere), and you will need the patched version of Odin that will allow you to flash a different firmware than your device came with. It seems like AT&t firmwares can be hard to find for some reason but there was this thread which has not been updated I don't think: https://forum.xda-developers.com/ga...ck-official-attoding965usqu3brj5-s9-t3866823. But it looks like that would at least get you over to AT&t firmware and then you could get OTA updates up to current hopefully. You might want to ask in that thread for further instructions on firmware and how to flash everything properly. You would want to use CSC instead of HOME-CSC, to wipe and fully set up the phone, and there is something which I don't know about called USERDATA, which I think might need to be found and flashed also.

hello, I am asking for, because I see a lot of people saying about diferent firmwares for each devices (AT&T, TMB, VZW, SPR) and the model is the same for all(G955U), I found in AFH an stock firmware but it says TMB, and I don't want to brick my device lol.
Can anyone share a firmware to our S8+ from Sprint???
If is possible, I am looking for QD9 version.
Thanks
without unlocked bootloader, you cannot flash anything. 955U has no unlock solution yet.
You can't Flash... but you can Odin stock firmware... anyone have Sprint stock firmware ?

I have noticed the baseband firmware is the same and there is a "user" firmware file that is strictly associated with the carrier. I have recognized this with Verizon and Sprint. ODDLY.. I have only seen these carrier firmware files included with the initial firmware release of the phone..
So Verizon launched its GS8 plus with one firmware release in advance of Sprints release of the phone.
So the two firmware files are NOT compatible given you are unable to downgrade and completely unprovission your phone.
Now .. I think the theory is that if you own a Verizon handset that has never received an update you can provision to Sprint .. granted you have the complete initial firmware set for Sprint.
Hi guys im having a heck of a time trying to flash U1 FW to my s9+ cause it has the stupid sprint lease lock on it so i'm trying to flash u1 to it. The U1 worked for my s8+ to remove the lock and sprint bloatware. I have a SM-G965U with build # G965USQU3ARG7 and i downloaded SM-G965U1_G965U1UES2ARF4 firmware but when i try to flash it just fails. i tired it useing prince comsy odin. tried odin 3b and odin v3.12.3 and none works they all fail.

The reason why it is failing is because you are on a high boot loader, you current on V3 while the U1 firmware that you was trying to flash is on V2.. You can only flash firmware that's on the same boot loader.
You would need to download G965U1UEU3ARG7 and flash it in order to be on the U1 firmware...

I don't believe the ARG7 for the U1 hasn't been released yet. I'm still on ARF4, I haven't gotten any updates for ARG7 yet.
But you can get the firmware using the link below when it becomes available. It's the same one I used.

To be honest it takes as long as it takes... Though for the U1 firmware it does appear to be the last one released after the carriers.
I would imagine that before they release a firmware that covers all the carriers they want to make sure it works for the individual carriers... But that's a theory/speculation I have.

He can't because he updated his phone to the latest sprint version which uses the v3 bootloader.
The current U1 firmware uses V2 bootloader.

First time I have ever heard of a Sprint Lease Lock.. Now I am curious over what that is, so off to google searching for it.
Think I found what your talking about... I am not sure if flashing the U1 firmware will work in this case given it's an S9+ and not an S8. Hopefully it does when the appropriate U1 firmware is released.
Depending on where you got the phones from maybe try doing a return and get a refund?

No biggie... Just for clarification (if it helps in the future) you can only flash files with the same bootloader version as what is currently installed. You can also flash bootloader versions that are higher then what is currently installed on the device.
What you can not do is flash bootloader versions lower then what is currently installed.
Finding the bootloader version is easy once you know how. Using the firmware version indicated:
G965USQU3ARG7
The bootloader version is the number before the last 4 characters of the firmware version... In this your looking for the number before ARG7... Since the number is 3 it means this firmware uses the version 3 bootloader.

Got it all flashed and back up and running... Just took a bit to restore everything and all my settings. Haven't seen anything amiss as of yet, sure I won't find out if there are any quirks until I let things settle for a day or two.
** Update 9/10 - So far so good, working like a charm. Even the wifi issue I had where it kept saying my internet might not be available (even though it was, and turning wifi off and back on would make it work) seems to be gone. Thanks for the link kevindevonwilliams

To carrier switch you would need to flash the U1 firmware, then insert the carrier of your choice [not Sprint] then set up device, after download the latest U firmware which is 3SARI4 and flash it.
Do not flash the USERDATA unless it is for the carrier you switching to
I ordered an unlocked model, G965U1 from eBay, but the seller sent me a G965U Verizon. At least that's the firmware that it has on it. I'm familiar with Odin and everything, so I'm wondering if I should keep it and just flash it over to what I want. Is this a viable option, I already had to send back a OnePlus 6T back to OnePlus, so I'm getting kind of tired of sending phones back.
Will the phone be just as good as what I ordered if I flash a different firmware on it, radio band-wise and such?The phone says I do not have a Verizon sim in it but I seem to be getting service from my T-Mobile sim.... Is this because all Verizon phones come unlocked? Sorry I'm just so confused with a different models and different bootloaders and different firmwares, so any advice would be appreciated!
Issue resolved, big thanks to user @jcsww!

What firmware does the phone have, from what US carrier? I I think the only thing you can try is flashing different firmwares to see if it will work. Maybe try converting it to a U S. factory unlocked G965U1, then the phone will reboot to configure the settings and features according to your sim card. No guarantee with this kind of thing tho.

You could try switching to the firmware for unlocked model G965U1, latest is 3ARJ6. No guarantee that it will make volte work though, that kind of thing is definitely hit and miss, and your phone is ideally suited for American carriers. But that's what I would try. You might also want to call up your service provider and see if they can do anything.

I flashed my Verizon G965U to G965U1. I used the patched Odin and used the CSC from the U1 firmware... My phone flashed and wiped, and then it booted up and detected my SIM card, then it rebooted again to configure all the settings based on my SIM card. After I did that I was getting the U1 updates directly to the phone.

This question has been answered already if I have the model numbers correct (via Google search). Does the model number of the phone contain SM-G965U OR SM-G965U1?
If it does then the answer is no. The SM-G965U and SM-G965U1 can only run official Samsung firmware.

I would have thought you knew (or if you didn't then this should explain why it won't work) that in order to do this we have to be able to unlock the bootloader, and/or flash a custom recovery to the phone, and/or if needs be root the device.
Because the phone is unrootable there is no means in which to unlock the bootloader and/or flash a custom recovery. By extension this means you can not flash a custom rom.
The only thing we can do with this phone is flash the official Samsung SM-G965U1 firmware onto the SM-G965U without issue (and vice versa). The only catch is the bootloader version of the firmware you are flashing onto the phone must be the same as (or higher then) what is currently installed on the phone.
