It is Samsung issued for testing by ??? and has not been released as of yet. Does that make it 'beta'? Probably. No developers contributed, which is a shame, the bugs would get worked out faster. Welcome to the new generation of ROMs.

I am on ARG8 TMB/TMB/XAA on an U1 device. How do I get it back to unlocked U1 firmware? I assume later in September the new U1 quarterly firmware will be out. Selling on swappa and need to restore.
[Samsung Galaxy S9+ Guides, News, & Discussion] yoyo711:
Just flush the U1 and to the Tmobile U

Thank you very much!!
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Download the U1 firmware, factory reset the device, skip through the setup and enable Developer Options and USB Debugging, boot into download mode, connect it to your PC and make sure the proper drivers are installed, open up the patched or modded ODIN, load in the files from the U1 firmware but make sure you use the OYN CSC and not the HOME-CSC, flash, and you will be back on U1 once the process completes.

You have to be on 3ARG8 build then flash this update via SD card.

Unfortunately, I wasn't able to tap dance my way into getting provisioned for WiFi Calling on AT&T. I tried seeing if they would "hard set" the IMEI from an AT&T S5 Active which supports it, but the system has no issue with auto updating IMEI as your SIM travels from phone to phone.

Your mileage may vary.

Have you tried just putting the SIM in your S5 Active, taking the update, and then putting your SIM back in the S9 Plus?
[Samsung Galaxy S9+ Guides, News, & Discussion] Psyscope:
Question do you have a regular AT&T account or business one? It doesn't matter what phone you have. I can give you an imei to use. If you are on telegram msg psyscope. I have one for a S7 edge and Note 8

If you tell them to make sure you have all the features on your account they should not remove them when you switch phones.

Yes, i remove the md5 for faster flashing

Basically, yes. Samsung creates many different builds along the way, during the testing phase. Only the final approved build actually gets pushed out as an OTA. But there shouldn't ever be any serious bugs in any of the downloadable versions that you see

What's the best way to get on to the latest version, without losing data, for people that are stuck on ARH1?
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
Which latest version? If you want to stay on U, then Odin back to ARG8 with HOME_CSC and use the update zips to go wherever you want. If you want to be on U1, you have to factory reset. Use Smart Switch and make your life much easier.

[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
Do you mean the 5th tab is missing? Some carriers remove that. Since the B series firmware isn't finished yet, it doesn't have all the things carriers like removed gone yet. For instance, on Verizon it still allows use of Samsung Cloud. Don't worry - before release, they will fix this "bug".

[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
You need to factory reset, flash to the U1, then flash to the TMB U with the TMB userdata.

Hello. I'm trying to flash the u1 firmware on my tmobile s9+ to make it compatible with the Verizon network. I keep getting a failed attempt it it hangs? I've turned usb debugging on and trying to use Odin and when I go into the downloader it fails the 1st time then hangs... Halp
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Do you have the correct drivers installed for your S9 Plus while it is in download mode? Have you tried another USB port? Shared ports tends to cause issues when attempting to flash. What is the bootloader version of your device and what is the bootloader version of the firmware you are trying to flash? You can not flash an earlier bootloader version! Most carrier devices are on the v3 bootloader. You will need to flash the v3 U1 firmware, if your device is on the v3 TMB firmware. You can find the bootloader version under Settings, About Phone, Software Information, Build number. The last 5 characters are the key. For example, my Note 9 is 1ARH2. The 1 is the version of the bootloader.
[Samsung Galaxy S9+ Guides, News, & Discussion] snootchies5171:
I'm currently at work when I get home I can get more information. Are devices still needing to be rooted ? Like back in the s2 -4 days... It's been awhile since I've done this. I switched carriers because I work for verizon and have been sitting in a tmobile s9+ that's not being used theoretically the T-Mobile one flashed with the stock firmware would work on Verizon, correct?
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
Absolutely not necessary to root the phone to accomplish this. But unfortunately, the currently published S9 software does not support the S8's "BYOD" functionality. Basically, that means that when you put another carrier SIM in the phone, it does pretty much nothing. So the process described here (flipping from U to U1 then back to U) is necessary if you want a full Verizon phone. But none of that requires root.

You'll need to download the leaked U1 build (3ARG7) in order to do it, because the carrier versions use bootloader 3, but the published unlocked firmware is only at bootloader v2.

But wait there's more! You might not even want to go back to U firmware once you see how clean and beautiful the unlocked firmware is. And in the version you'll be installing, you'll even be able to use Wi-Fi Calling. All you'll lose by staying with unlocked is video calling. Now if you need that for your work with Verizon, I totally understand.
[Samsung Galaxy S9+ Guides, News, & Discussion] snootchies5171:
Awesome! So I should try using the methods afforementioned to get it to work? Maybe I'm missing a step. Not sure.
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
Well, you didn't provide a lot of specifics, but I'm guessing the bootloader version is your problem. Anyway, here's the firmware you'll need for the new (unreleased) U1:

https://androidfilehost.com/?fid=1322778262903999031

This build will factory reset your device, because it does not include a HOME_CSC. But since you'd be flipping form U to U1 (or vice versa) you'd want to do that, anyway. Have fun.
[Samsung Galaxy S9+ Guides, News, & Discussion] snootchies5171:
Yeah I'm at work. Here for only a couple more hours so I'll have more specifics when I am home! But thank you!

What do you have a business account? Switching sims should not effect features, unless you call them to add the imei. Do you want an s8 IMEI for ATT. PM me. I'll give you one.
[Samsung Galaxy S9+ Guides, News, & Discussion] mc_365:
I'm using my U1 S9 on VZW. I've flashed the U VZW firmware and userdata to my phone several times, using both the stock Odin and the Latest Modded Odin. When I go into advanced calling after flashing I can activate it and I get some VZW popup then HD Voice is selectable but Video Call is greyed out. On my VZW account it says it's blocked, when I try to activate it, I get the message that it "can't be saved to my account, call customer service". If I switch my SIM to a VZW phone the block is removed, put the SIM back in my S9 the block immediately returns. All other HD calling options look like they are working from my phone but I didn't really test them beyond selecting them in the menu and seeing them as active in my VZW account.
[Samsung Galaxy S9+ Guides, News, & Discussion] ednometry:
Not sure but my SIM card was used and activated in my Verizon branded s8+ before I moved it to my s9+. On my phone HD voice and video calling are one option together and I never had to activate it. It was already on when I opened the menu. My phone was running U1 firmware with the Verizon SIM and did not have that option until I flashed the vzw firmware over it. Once I flashed the firmware all the features appeared along with a few new apps and bloat ware. I have verified that Video calling works for me by video calling a friend as well. Process was easy, sorry for your troubles.
[Samsung Galaxy S9+ Guides, News, & Discussion] Rehvix:

I have the same problem with my Verizon branded S9+. I think it's something on your account.
[Samsung Galaxy S9+ Guides, News, & Discussion] mc_365:
You should look at your accounts Blocked services. I can not turn the block of video calling "off" when the Sim card is in my Unlocked Galaxy S9. When the Sim is placed in a VZW sold phone the block automatically turns off.
[Samsung Galaxy S9+ Guides, News, & Discussion] aka120:
I just thought I would chime in here with my experience. I've got the unlocked S9+ SM-G965U1 purchased directly from Samsung. My carrier is AT&T and it bugged the ever living s**t out of me that during a call the network drops from 4G to 3G (i.e. from LTE down to HSPA+ or HSPA). This is just not acceptable to me, I had an unlocked Galaxy S8 and it exhibited the same behaviour. All my unlocked HTC One's 7, 8, 9, and 10 maintained LTE during calls, so the unlocked Galaxy S8 and S9 are looking primitive to me. I figured if I throw AT&T's carrier bloat on top of the S9+, Sammy will play nice and hold on strong to LTE during a call, and for sure that is the case.

But, I had taken the RBG update already and there doesn't seem to be an RBG update for AT&T or I couldn't find that version anyways... I decided to bite the bullet and downgrade back to RB7 using SM-G965U with AT&T's userdata. I used the patched Odin version tran1981 posted a link to in post #51, and flashed away. It's obviously a must to wipe data in order to get AT&T's carrier specific features to work with Sammy, and once booted up you'll have most, if not all features. LTE now remains during calls no more 3G crap while on a call. Visual voicemail is working great, VoLTE or HD voice is working great as well. I haven't tried the video calls or wifi calls but I can only assume those features are working fine too.

Uninstalled/disabled most of the AT&T bloat and my only (minor) gripe is the AT&T logo on the status bar, the annoying boot up animation, and shutdown animation... But I can live with it.

tl;dr

Flashed G965U RB7 and AT&T userdata using patched Odin on my SM-G965U1 and all features I wanted working are working great.
[Samsung Galaxy S9+ Guides, News, & Discussion] Venom0642:
You should of got the AT&T S9 Plus version unlocked phones depending in area won't work good on some carriers, in your case AT&T. Plus unlocked are the last to get OTA.

---------- Post added at 02:52 PM ---------- Previous post was at 02:44 PM ----------

Also unlocked phones you lose some features AT&T has like wifi calling and Volte as well.
[Samsung Galaxy S9+ Guides, News, & Discussion] NotATreoFan:
I have the TMO version, direct from them. Before I found a newer version of Package Disabler Pro that worked, I tried flashing the unlocked firmware to it so I could remove the bloat included, which is arguably a heck of a lot less than other carriers. We don't lose WiFi Calling or VoLTE, but we lose advanced messaging and are relegated to basic SMS without the TMO userdata being present.

Did you flash all the RB7 Files (in my attachment) and userdata at same time ? Which VVM did you use, the one installed? or did you add one from play store or sildeload. I had to get mine from apk mirror but it worked, That was the only ATT feature i could get working. Does the caller ID/SPAM feature work on the dialer? I'm trying RB7 now to try again. If you left anything out at all let me know please. As far as i know you are the only one with a U1, flashed to U that is getting all of ATT features to work. Did you have to call them?

[Samsung Galaxy S9+ Guides, News, & Discussion] aka120:
Yes I flashed all of the RB7 files, the only difference is that I flashed the csc home file instead, and then did a factory reset.

I'm using the stock preloaded at&t vvm app and it's working flawlessly.

I'm not sure about the spam feature working in the dialer but the at&t call protect app seems to run fine. The caller ID is working in the dialer, but I'm unsure if that has anything to do with at&ts service or if it's baked into the stock fw.

I did not call at&t at all, all features, even wifi calling worked after setting up the services, i.e. launching vvm app and going through the setup process.
[Samsung Galaxy S9+ Guides, News, & Discussion] nugzo:
In software settings, service provider. Do you show ATT/ATT/ATT or ATT/ATT/XAA ? also mind showing a screenshot of the wifi calling setup? Where you tell it your location for 911 calls? Thanks so much. If you did it, there's gotta be a way. Did you restore from any backups or setup as new? I'm going to try the home csc now. Did you boot directly to recovery after the Odin and do a factory reset? or did it boot to start screen then you reset and did a factory restart?

Mind showing a screenshot of software page? maybe that could shed some light on things. Thanks for your trouble. You've figured it out and we're all dying to do the same. Thanks again.

Can I use the new U1 ARG8 coming from U ARG7?
[Samsung Galaxy S9+ Guides, News, & Discussion] guyd:
I'm confused by your post. The currently published S9+ (unlocked U1) software does indeed support the "BYOD" functionality, as that's what I'm currently using on Verizon. It does not have WiFi Calling, but the rest works perfectly. And it seems that will be fixed in the next published release.
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
Not sure where the confusing part was. What you say is true. If you just want a phone that works on any carrier with basic functionality, the current U1 will work. The problem would be if you have a U phone, then it will not work on any other carrier today, because of a lack of BYOD. That would require flipping to U1, first. You can't do that using only published software, since no U1 BL v3 exists (officially).
[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
I installed the latest U1 firmware but it was still July security patch, so I converted back to the U firmware without cricket user data so now I have an AIO/AIO/VZW phone. Can someone post the USERDATA for Cricket Wireless so that I can convert the phone to VIO/VIO/VIO cos currently I only have the cricket splash screen when the phone starts up but I dont have VOLTE nor WiFi Calling which would be nice.

I'm not getting it on the 3ARG7 firmware. Does Samsung do staged rollouts or do they not update unreleased builds?
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
Likely the latter. Use SamFirm to grab it, and flash with HOME_CSC so you don't have to factory reset.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Why would there be a need to update something that wasn't released? The purpose of the v3 bootloader U1 build is essentially to help people switch from one carrier U build to another. If you choose to run an unreleased build, don't expect much.

Unofficial, yes.

The confusing part of your original post was this statement

From a U1 device users perspective, that's not true. That's what I meant by a "little confused" by your post. I can see now that the larger context of the conversation was in reference to helping someone switch carriers by switching to U1 first, and then back to the U of that carrier.
