Has anyone been able to get WiFi calling or VOLTE to work on the U firmware? I haven't been on it in a while.
Edit: not sure why i quoted you for this question. Lol sorry.
I have been trying to get it working as well. I wish that att would support wifi calling like T-Mobile does I only get 1-2 bars and sometimes no signal when I'm at a certain spot in my workplace and when I had the original att software on my phone I loved wifi calling, I don't particularly miss VOLTE though
Thank you so much for doing this. I was using the wrong Odin to flash.
Quick question on this. Now that I am running the U firmware, will I get OTA updates? I'm using a Cricket sim card.
I hated the AT&T firmware so much. I'm so much happier with this.

Yes, you will be able to receive U firmware OTA updates.

Need to flash T-Mobile firmware in order for at least wifi calling to work.
after flashing this firmware.. I noticed a huge gain in performance.
and mobile hotspot works, I run cricket unlimited, and will come in handy.
I like the clean appearance and the smooth responsiveness, I used the AT&T firmware and I used PDP to disable a ****load of bloat, but nothing like this smooth.
not to mention I'm getting updates, which I'm more happy about.
this is really nice to have.
Had anyone tried this and used on rogers?
loganbeck14 said:
To begin make sure you have samsung usb drivers installed. Now make sure you use Princecomsys modified odin, next download the latest U Firmware from here https://www.androidfilehost.com/?fid=817550096634768085 or here https://www.androidfilehost.com/?fid=457095661767159704. Next put your phone in download mode and open odin make sure all firmware files are in the right spot and click start wait until your phone boots into recovery mode and restarts, after that to clean up old temp files factory reset in recovery when your phone boots to the welcome screen, after that you are finished. THIS is For att and tmobile phones only unless your verizon phone is using one of the two carriers sprint won't work due to proprietary activation processes. Thanks to Princecomsy and muniz for providing odin and the firmware files for this version

As long as you had att unlock the phone you are fine
I bought it "factory unlocked" so I'm not sure who did it. What would happen if att didn't unlock it?
Please help me understand
I see some forums on this site that says, " G930UUEU2APEH flashes to g930a" then you have this post that says G930U firmware on SM-G930A. It seems as if one is saying to take the G930U and go to G930A and the other saying G930A and go to G930U. I thought the advantage is to go to the U and get off the A. Please confirm if this is the case. Granted then if this is the case... then, what are the advantages of going to the U? From what I understand it gets rid of the bloatware, and makes it so you can tether?
Also once I go, are there any negative reasons for me not to go from A to U?
Does this give me the current version of Nougat?
Do I get the upgrades from AT&T to keep up with future version of Nougat?
Also before proceeding to the U version MUST I first ROOT my phone?
Also MUST my phone be UNLOCKED?
Thanks in advance,
DavyCrockett said:

Yes to both

None, unless you like the ATT bloat.

Gives you the latest version of the U firmware
Do I get the upgrades from AT&T to keep up with future version of Nougat?
No, you will get the U OTAs from now on.
Also before proceeding to the U version MUST I first ROOT my phone?
Root is not required
Also MUST my phone be UNLOCKED?
Not required

Goto updato.com to download the latest Verizon stock firmware. Extract and flash the files in Odin. If you flash all the files (AP, BL, CP And CSC) you will wipe everything on the phone so backup first. If you don't want to start over, then just flash CP and CSC.
There are two versions, 955U and 955U1. The U version is carrier specific and will contain their own software bloat. The U1 version is unbranded so no carrier bloat.
If you need more details, search for carrier switch.

What makes you think the phones unlocked? Did you buy it from someone on their word that it's unlocked? Had sprint confirmed it unlocked or have you used a 3rd party unlock service? Did you just flash unlocked software?(if so that's not carrier unlocked just unbranded without sprint junk)? More info needed to help

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.
Use Odin3 v3.13.1_3B_PatcheD for flashing U1 firmware on your Sprint SM-G965U

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.

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?

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.
