If you'd actually searched or read the forums, almost every thread regarding firmware has said the U1 is scheduled for quarterly updates, which means likely not until the end of next month. There's no ETA because it's entirely up to Samsung. You'll just have to keep checking the forums for a post. There will be multiple threads when it comes out just like there are for all the current firmwares.
[Samsung Galaxy S9+ Guides, News, & Discussion] Psyscope:
No, you need to have had an ATT capable phone on your ATT account. It has to be a Samsung one.

You must flash U CSC on a U1 phone, since the last update ATT took out all the branded ATT features with the CSC. I opened the U1 and U firmwares and compared them. The U1 had itself stripped of features.
[Samsung Galaxy S9+ Guides, News, & Discussion] moosedemon:
Did you have any luck with this? Also, would this give me VoLTE?
[Samsung Galaxy S9+ Guides, News, & Discussion] CharmedWhovian:
Quick question, If I do this to my Sprint S9+ going from Sprint to Verizon or to ATT will I be able to use my sim card and will I have to pay to have my phone unlocked network wise.

Side note;

Sprint says that my y phone is eligible for unlocking, but due to the guy who sold it to me is not available they won't do it. And unlocking companies keep failing. So could I use this to do that switch it from Sprint to ATT and use the phone. Also should my sim card be in it or not
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Get your device SIM unlocked first. When you factory reset and flash to U1, having your SIM in it doesn't really matter because it is a stepping stone. You are basically going to flash again once you re-enable USB Debugging to the U firmware of your choice.

[Samsung Galaxy S9+ Guides, News, & Discussion] nowerlater:
I'm on ARH1, just didn't want to go back

Link available?
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
Hey, I have a SM-G965U (originally on Verizon) and currently on ARG8 build number. I flashed via Odin the Unlocked firmware then the T-Mobile firmware to get my device 100% T-Mobile looking a few months back. How do I go about getting the device back to a Verizon firmware and looking like a Verizon branded phone? The same route? Unlocked then Verizon? Does the ARG8 firmware matter? Thanks in advance.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Pretty much! A full wipe to U1 is always the stepping stone to channging to another U firmware.
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
I just remember back in the day using Odin with the wrong files could potentially brick your device. Really trying to do my research so that doesn't happen lol
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
It is much easier than the days of the old Galaxy Nexus and such.

Enable Developer Options and USB Debugging.

Boot your device into Download Mode and plug it in via USB.

Load up modded or patched ODIN.

AP, BL, CP, and CSC_OYM for U1 / AP, BL, CP, CSC_OYM, and userdata for U.

You always flash to U1 first when coming from a U.

Don't change any of the ODIN default options and flash.

It will finish and reboot to the setup.

It is a lot easier than it was. I literally stayed away from Samsung after the Galaxy Nexus up until the S9 Plus, which I had two, and now a Note 9 as well. I have flashed all 3. If your flash doesn't start, try a different USB port and make sure you have the correct Samsung USB drivers installed.
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
Ok cool thanks for the easy step by step. Just find the latest U1 firmware and the latest Verizon firmware?
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
SamFirm and Updato should have them. Both aren't exactly quick. Some of the OP's in the firmware threads have them on AndroidFiles as well. If you are on the U1 already, you can flash directly to the Verizon firmware. It is still recommended to factory reset first though. You need to make sure though it has the same bootloader version or newer though. You can't flash a firmware with an earlier bootloader. If you look under Settings, About Phone, Software Information, and Build Number. The last 5 characters of that are the important stuff. The number at the beginning of the last 5 is the bootloader version. So, 2ARF4 as an example, is bootloader v2.

If you are on a U firmware, you must flash to U1 first and full wipe. If you don't factory reset, you could end up with a partial conversion and run into a lot of issues.
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
I am on the T-Mobile firmware so that's the U and I'm on 3ARG8. Does it matter which U1 firmware I grab? I see there are 2 versions available in the OP's download, RB7 and RF4?
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
As long as they have the v3 bootloader, you will be fine. The 3 in 3ARG8 is the bootloader version. If that number is a 1 or a 2, you will not be able to successfully flash those since your device is already updated to the v3 bootloader. Currently, there is no v3 bootloader for the U1 firmware. The expected date for the next U1 release is around the end of September.
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
Dang, ok thanks for the explanation. So I cant get my device 100% back to Verizon from T-Mobile until the v3 bootloader for U1 is released. And once it is I will flash it then the v3 of the Verizon firmware and I should be good to go.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Exactly! That is one advantage to sticking to the U1 over the T-Mobile firmware. Because the U1 is the last to get updates, you are always good to switch if needed. However, you lose video calling and advanced messaging on T-Mobile when using the U1 over the U but T-Mobile's WiFi Calling works on both the U1 and U.
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
Well I'm doing this because I need to sell it. And when I try to list it on Swappa it knows it was originally a Verizon device but the device is currently on T-Mobile and when I boot up the phone it says T-Mobile and everything. I'm not sure if this is a big deal or not, but I figured I would put it back on Verizon since Swappa knows.
[Samsung Galaxy S9+ Guides, News, & Discussion] ombheembush:
Is there even a way to go back to ARG7 from ARH1 without losing data?
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Hmmm. I don't see how Swappa would know the firmware has been changed, but they do offer up some of the best device checking to ensure buyers don't end up with something they don't want. Even though the IMEI is tied to Verizon, you should still be able to sell it as a T-Mobile device. Cross-flashing via the modded or patched ODIN doesn't actually trip Knox or SafetyNet because the hardware for all U, U1, and W g965 models is the same.

Under Service Provider in the Settings, Software Information, the last of the 3 tags is essentially the carrier you bought it from where the first two are the carrier firmware it is currently running. If you were to buy an XAA U1 for example, it would say XAA/XAA/XAA until you put a SIM in it. Then it would change to TMB/TMB/XAA, if your carrier SIM was T-Mobile. This would change again if you swapped out the SIM for one from ATT, VZN, SPR, etc.

If Swappa still doesn't allow it to post successfully, unfortunately waiting for the U1 firmware to convert it back is your only option outside of sending it in to Samsung to be reflashed by them, which won't be covered under warranty. You could potentially try Ebay since their restrictions are a lot more relaxed but it is Ebay. :P
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
When I tried to list it on Swappa via the app it said S9+ Verizon, but I can manually say its a T-Mobile S9+ if I list the device on Swappa.com. Also when I do Check IMEI on Swappa it says its a Verizon S9+. I guess the stock carrier info is tied to the IMEI number? I've just never sold anything on Swappa so I wanted to make sure I'm not breaking any rules.
[Samsung Galaxy S9+ Guides, News, & Discussion] NotATreoFan:
List is as a Verizon S9+, tick the box that says it's been Rooted/Modified, and explain that it's currently running TMO firmware. You may find someone on TMO who wants the VZW hardware since there is no SIM lock on it.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Swappa does have a modified software rule, but technically, the software isn't modified. You are using the factory stock T-Mobile firmware that exists on every other T-Mobile S9 Plus sold by T-Mobile.

The IMEI is tied to the carrier for companies like Verizon and AT&T to restrict specific feature activation on their network on devices not sold by them. WiFi Calling is a perfect example. However, T-Mobile does not participate in this practice, so everything should be fine if you manually select the device as a T-Mobile device. I guess the only thing that might give it away, is if the device actually has the Verizon logo on it. Hopefully it doesn't.
[Samsung Galaxy S9+ Guides, News, & Discussion] NotATreoFan:
Swappa will require it to be listed as a VZW device, because that's where it came from. But he can mentions it's modded with TMO firmware, and that does not break any rules.
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
Nope no Verizon logo on the device. The only thing that gives it away is the last abbreviation that you were speaking about earlier, it says something like Tmo Tmo Vzw instead of all Tmo.
[Samsung Galaxy S9+ Guides, News, & Discussion] daniel4653:
Even though it's easier today my hands get sweaty and I get nervous when flashing u and u1 firmware lol. I had no issues flashing odin back in the day when it could brick you phone. Lol. (Epic touch, S3, & S4.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Ahhh. I know they have a policy that mentions root. It isn't rooted and is stock firmware, just not the original stock firmware that shipped with it. I know a lot of people that wouldn't understand that though. Hopefully they don't have any issues selling it. If so, a month wait for the firmware hopefully won't be too bad for them to get it flashed back and sold with ease. The holiday shopping season is creeping up fast. The S9 Plus is still basically on par with everything else out there right now.

Most probably wouldn't even notice then, but personally, being honest about it at least covers your end.
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
Yeah I will probably list it as a T-Mobile device and say in the comments its completely carrier unlocked and was originally on Verizon. If all of the carrier models are SM-G965U then I don't see why it would matter.

Can I flash this (HA or H6) on my ATT bootloader ver 3 then flash Tmobile firmware or the only way is waiting for ver 3 U1 firmware. Running Tmobile service with ATT S9 + firmware sucks.

Thanks
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
If you update to HA or H6, your carrier will SIM swap. You could then Odin back to ARG8 stable. Or you could just stay at HA or H6 for the time being. I'd recommend going back, though.
[Samsung Galaxy S9+ Guides, News, & Discussion] sweetboy02125:
To be clarify, I just need to "dirty" flash HA/H6 U version with my ATT S9 plus, then flash ARG8 Tmobile ver and I'm all set? Will my ATT S9+ will be update OTA when Tmobile update?
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
I guess if dirty flash means to use the update.zip, then yes. Let the phone boot. You should already see TMB apps and splash screen while on BRH6/A. If so, then you're all set. Do a full Odin back to ARG8 (CSC, not HOME_CSC), which will factory reset the device, and then you're golden. Yes, you'll get TMB OTA from that point.
[Samsung Galaxy S9+ Guides, News, & Discussion] sweetboy02125:
Thank you, Got my ATT converted to Tmobile. "Dirty" flash meant flash without wipe.

So i use update.zip (BRH6), my ATT phone got wipe and Tmobile logo. Then I odin back to Tmobile ARG8. It's all set now
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
That's exactly how you do it. Glad it worked as planned.
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
G965U1 bootloader 3 has been added. There is no HOME csc available for this yet, so this firmware will wipe your device if you flash all 4. Don't flash CSC if you want to avoid that.

It is best to use the U firmware for your carrier, if you want to have all of the features your carrier offers. An update is very different from a full firmware. You can't use an Update.zip to switch carrier firmware.

[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
Wi-Fi Calling on Verizon with U1 is enabled by a new APK which has been added.

com.verizon.loginengine.unbranded

It's displayed as Carrier Login Engine. It appears to have a similar function to the UI-less "My Verizon Services " (not to be confused with the My Verizon app) which is baked into U firmware for carrier devices. Once Carrier Login Engine has been given permissions (which you'll be asked to do when you attempt to enable Wi-Fi Calling), the usual Wi-Fi Calling APK will be invoked.

Samsung also changed the permissions on the Wi-Fi Calling APK to allow the Verizon activity/intent to proceed. In prior U1 builds, a shortcut maker type app could invoke other activities on the Wi-Fi Calling APK and you could see the dialogs for certain carrier's Wi-Fi Calling setup screens, but never Verizon's (although it was clearly visible in the intent list).

I don't know if this will prove useful to anyone, but this is how they did it.

TL;DR, the total changes to U1 to make this work are:

- Add Carrier Login Engine to U1 firmware (see above for the full package name)

- Change permissions on the existing Wi-Fi Calling APK to permit the Verizon activity to be executed by non-root user

Remaining question: What does Carrier Login Engine do? Why is it needed? Well, a differently named APK asks for permission with the Sprint SIM profile when attempting to enable Wi-Fi Calling on the U1 firmware. So it looks like they've got the same thing. Verizon has simply added theirs to the newest build.
