Thanks - that is more in line with what I had thought. Still leery of futzing up something with my company's compliance checks on the phone or getting out of sync with updates should AT&T ever decide to push them. Ever.
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
I imagine ATT will push the ARE6 update. Sprint has it, i think t-mobile does as well, but I'm not 100% sure on that. Although after the ARC6 update being pushed over bootloop issues, I could see ATT waiting a week or two after it's been pushed fully to a carrier or 2.

Going backwards old System apps in 2ARF4,

2ARF2 is much newer just thought i mention it, that's why everyone in Discord are not using 2ARF4.

Any idea why safteynet is failing on me? play store says certified but when I run the safteynet test app it hangs for like 4 minutes loading and ends up failing. Also when updating apps the play store hangs a while when my downloads speeds are 100mbps. I was originally on tmobile feb 1 patch, flashed G965USQU2ARE6 using home csc, did not factory wipe my phone then right after flashing U2ARF2 via recovery.
[Samsung Galaxy S9+ Guides, News, & Discussion] Venom0642:
Try a different Safetynet app the one you probably using is way outdated and for the download issue try going back to recovery and do a wipe cache.

[Samsung Galaxy S9+ Guides, News, & Discussion] Jaimesco12:
Yeah wiping cache did not help, play store still hangs when downloading apps for a few minutes then it downloads them. I guess the only solution here is to factory reset.
[Samsung Galaxy S9+ Guides, News, & Discussion] bboii86:
Sometimes updating to the latest Google playstore helps.

https://www.apkmirror.com/apk/googl...5-10-all-0-pr-199875543-android-apk-download/

After installing the latest Google playstore, clear data/cache on the Google playstore app, restart your device and sometimes that does the trick.

Happen to have a download link for 2ARF2?
[Samsung Galaxy S9+ Guides, News, & Discussion] FatalONEM8:
Hey you guys, I think there might be a way to do this after all, even on BLv2 which surprisingly the U1 STILL doesn't have. Open up the CSC tar for the U1 Odin files and extract sec_omc.zip and place this on your sd card, then flash it in recovery, then from there it may be trial and error because I've never seen anyone do it before but anyway, extract the sec_omc.zip from the U2ARC6 or whatever firmware as well and put that on your sd card and flash that. Hopefully once your phone boots it'll be whatever carrier your sim is. You might also have to boot into the phone maybe so it can reprogram while you have the U1 CSC installed, you most likely will also have to wipe data. Hopefully you or someone else can test. [MENTION=3116388]jcsww[/MENTION] I think you'd be interested in this as well, let's see if we can't get this working. The person who found out you can flash this zip in recovery is [MENTION=1949695]jrkruse[/MENTION] and this gave me an idea for you guys. I really hope this works!!

This worked successfully on the AT&T Galaxy S9 Plus on the V2 bootloader. However, it didn't change the AT&T carrier logo or bloatware on startup even with a VZW (Non-Active) SIM card installed. the service provider SW version says SAOMC_SM-G965U_OYN_ATT_OO_00744650534657463098 ATT/ATT/ATT. And I have no idea how to get that to say VZW/VZW/VZW. And for whatever reason when I stuck an active Verizon SIM in the phone on this software, even though my phone is SIM unlocked, it won't read a VZW SIM card at all. It shows signal, but says emergency calls only and that's it. And I have no idea how to get around this.
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
I believe you would have to go to the U1 version first, before flashing to Verizon. That means your stuck until the U1 V2 bootloader files drop. I'm not 100% sure, but believe that's the only way to swap carrier branding is to be on the U1 firmware first.
[Samsung Galaxy S9+ Guides, News, & Discussion] cjegan2008:
Okay, but what about what's going on with the SIM card slot ? Why is it not reading a Verizon SIM card even though it's unlocked ?
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
I am almost positive that ATT Sim locks all phones. You normally need a PUK or Pin Unlock Key. ATT typically wants like 60 or 90 days of payments before they will unlock it. If it's fully paid, they may still make you wait 7 or 10 days after purchase to verify its not a fraudulent purchase.

Edit: Just confirmed. Mine is Sim locked, and under my line I can request a PUK.

Edit 2: it isn't a PUK code, there's another section in my account to "unlock a device". So again, mine at least is Sim locked.
[Samsung Galaxy S9+ Guides, News, & Discussion] cjegan2008:
Okay but my phone is already SIM unlocked. I can use any SIM card on this phone. Problem is, it's not reading Verizon SIM cards.
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
I would try contacting ATT and make sure it's truly sim unlocked. They typically sim lock their phones by default last I knew. Failing that, I'd try getting a new sim from Verizon. Last dtich effort, I know when I had Verizon, you had to activate a sim to a particular phone. I tried swapping a sim to another phone and had to call Verizon.
[Samsung Galaxy S9+ Guides, News, & Discussion] Scott:

Do you know of any resources I could check out about the pull? I read about it a while ago but have not really looked recently.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:

I have that ARC6 update and I have no issues that I can tell
[Samsung Galaxy S9+ Guides, News, & Discussion] Scott:
Most people willnot see the issue> Finally got home from work and had time to research this. The issue is a bootloop would ensue after the update completed. So if your update compeleted then you wont see the issue.

So... I tried to update my Verizon device with this T-Mobile file. It flashed it and no errors however, its not flashed. Like a write protection. I was one firmware version ahead of this one. I think that may be causing the issue.

I need to take more time and research. I have done a lot of things with Android devices before but I have never switched carriers and retained the same device so this is actually new to me!

I purchased an ATT model G965U for use on T-Mobile. I flashed the XAA_G965U1UEU1ARBG_ODIN_Files and checked the Settings on the phone, it was then showing G965U1 (as expected).

Following the move from U -> U1, I used Odin 3.13 (patched) to flash the T-Mobile files TMB_G965USQU2ARC6_ODIN_Files (AP, BL, CP, HOME_CSC, and USERDATA). However, the CSC appears to have no affect. Under Service provider SW ver. it says XAA/XAA/ATT. I assume this is due to my not inserting my SIM card until AFTER I flashed the T-Mobile firmware. Reinsterrting the SIM does not prompt a reboot and I have tried restoring to factory settings and wiping the cache.

I am on 2ARC6 but my CSC is XAA, is there any way to change the CSC to TMB?
[Samsung Galaxy S9+ Guides, News, & Discussion] cjegan2008:

Here's the link to the latest U1 firmware if needed.

Download here: G965U1UES2ARF4

DOWNLOAD for ODIN:

ODIN v3.13.1
[Samsung Galaxy S9+ Guides, News, & Discussion] Scott:
Can you please clarify, this is the unlocked version software? The one we need to flash to our device to be able to flash a carrier ROM?

EDIT: NVM. I see that this is indeed XAA!

Your the man!
[Samsung Galaxy S9+ Guides, News, & Discussion] 52me52:
So for those on 2ARC6, will this flash us to T-Mobile ROM?
[Samsung Galaxy S9+ Guides, News, & Discussion] bboii86:
Yes. It will help. What you trying to do? CSC switch? to have the boot logo be T-Mobile with all the features and bloatware?
[Samsung Galaxy S9+ Guides, News, & Discussion] 52me52:
Yes I've been stuck on At&t 2arc6 for a while, this would flash my current At&t bootloader V2 to T-Mobile? Definitely need TMobile features
[Samsung Galaxy S9+ Guides, News, & Discussion] bboii86:
Do you have a T-Mobile SIM?
[Samsung Galaxy S9+ Guides, News, & Discussion] 52me52:
Yes, I was on v1 but I missed a step when flashing v2 and I've been stuck on At&t 2ARC6 since then.
[Samsung Galaxy S9+ Guides, News, & Discussion] bboii86:
Okay, follow these steps.

*Make sure to back up your data*

1. Download the U1 firmware S9+.

Download here: G965U1UES2ARF4

2. Download this Odin.

DOWNLOAD for ODIN:

ODIN v3.13.1

3. Make sure the T-Mobile SIM is inserted. Leave the Sim in the device, the entire process.

4. Shut off the device.

5. Put it in download mode.

6. Flash the U1 firmware 2ARF4.

7. Once flashing is complete. You'll be promt with a reboot and restart device. Press okay. That's just the device trying to reconfigure and recognize the T-Mobile SIM.

5. Once the device boots back up. Turn off the device.

6. Put the device in download mode.

7. Now flash G965U software.

Download here: G965USQS2ARF4 Use the same odin to flash.

8. After that's completed, it should now boot up with the T-Mobile logo, it will have all of T-Mobile bloatware and features. Working 100% Then you're good to go.
[Samsung Galaxy S9+ Guides, News, & Discussion] 52me52:
Thanks, I'll try it!
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
J1 is the non-carrier US firmware. It will install your T-Mobile settings, APN, WiFi Calling, etc., but it isn't the specific TMB U firmware.

[Samsung Galaxy S9+ Guides, News, & Discussion] Iain_S:
the SM-G965U1 firmware does flash to the Canadian version, the latest with June security update does flash but fails odin, it will install after a reboot and clean install, Samsung health and some other apps will fail to run saying your phone has been rooted. I have since gone back to the XAA Canadian firmware.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Everything works fine on my G965W running the latest U1 and the same goes for my mother's G965W running U1 that was updated yesterday. If there were any issues with the apps she uses, including Samsung Pay, I wouldn't hear the end of it. Did you use the modded or patched ODIN to flash?

How do I get rid of T-mobile BLOATWARE? Can you tell I don't like it NONE OF IT!:(
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
ADB or flash with a full wipe to U1.
[Samsung Galaxy S9+ Guides, News, & Discussion] coolbrezze67:

[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
If you did that and still have T-Mobile bloat. Something didn't go right.

Did you factory reset the device, including userdata, before flashing?
[Samsung Galaxy S9+ Guides, News, & Discussion] cjegan2008:

---------- Post added at 04:37 PM ---------- Previous post was at 04:35 PM ----------

Did you successfully get rid of the T-Mobile bloat ?
[Samsung Galaxy S9+ Guides, News, & Discussion] coolbrezze67:
I did the second time, but it still is bloated. It gave me an error message in Odin that it failed
[Samsung Galaxy S9+ Guides, News, & Discussion] cjegan2008:
Okay flash the phone with this version of odin https://drive.google.com/open?id=1kQ2-Dj3uBHPKtSMA2M-GM52KkKNbDg4p

Using this U1 Firmware https://drive.google.com/open?id=199vo-n8OMq991CO1fUR-2uB4PzahJqaw. It will fully convert it to a U1 Device.

Press the power button, volume down button and the bixby button at the same time until the you get to the download mode screen. Press up on the device once you get to download mode and then connect the device to odin. Put the BL, AP, CP, and CSC files in the same order they are listed in Odin, and then click start. Once completed it show a samsung startup screen with no T-mobile logo. It completely is stock U1 after you first boot up. Once you get to the setup screen it will ask you to reboot the device to import carrier settings from SIM card, click okay and dont worry it will still be U1 once it boots up no T-mobile bloatware. And then your done. You should have a fully functional U1 device
[Samsung Galaxy S9+ Guides, News, & Discussion] cjegan2008:
Can you post the U1 software for the S9 to that has the v2 bootloader that does the exact same thing as the S9 plus variant ?
[Samsung Galaxy S9+ Guides, News, & Discussion] bboii86:

[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
As someone else said, the OTA's almost always work with Samsung Pay, because it does not trip Knox. Google Pay relies on Safety Net, but Knox is considered "more secure", so Samsung Pay relies on that instead.

That said, I did encounter problems with Samsung Pay on one of the earlier OTA's. Typically if you have a problem, you have to wipe the data from the Samsung apps, factory reset, and then start again.

[Samsung Galaxy S9+ Guides, News, & Discussion] _Sasan_:
I have an unlocked S9+ version. My problem with the unlock version was that the inconsistent and slower lte internet speed and lower coverage bars than my previous T-mobile S7.

Pros of Tmobile firmware:

Better LTE speeds and better coverage in the same location(for me at least, I also compared it with my friend's unlocked galaxy s9+)

HD Audio icon now shows up in the call and quality is better (I dont know if the quality is placebo or not)

Video Call button now shows up in the dialer.

Cons of Tmobile firmware:

It has crippled the Smart Caller ID and spam protection feature ( workaround: Install Hiya from Store)

Works in both:

Wifi Calling and VoLte.

if you plan to upgrade to Tmobile, firmware remember that you have to select the userdata which can wife your phone to factory setting. And as the OP mentioned this specific firmware has V2 bootloader so you will not be able to revert back to U1 firmware until that also gets update to V2 bootloader.
[Samsung Galaxy S9+ Guides, News, & Discussion] bboii86:
If it's the LTE speed and signal that you're concerned about, there's a way around this. The unlocked model has every single band for any carrier. All you would have to do is select the bands you really need for your carrier, to experience full throttle LTE speeds from your carrier. The reason why the speed slows down, because all the bands are still available. The more bands available, the longer it takes for your device to search the bands it needs for your carrier. Thus making your LTE speeds slower. For example for:

T-Mobile bands

LTE 2/4/5/12/66/71

WCDMA 2 (1900) / 4 (1700)

AT&T bands

LTE 2/4/5/12/14/29/30/40/66

WCDMA 2 (1900)/ 5 (850)

To fix this, there's a secret menu inside the phone, where you can gain full access to your LTE bands and select the bands you really need for your carrier. First you would need to take your sim card out of your device. Then restart your device, go to the phone keypad and type *#2263# A service mode menu with all your available bands will pop up. From there press clear all bands, then select LTE band preference and select the bands for your carrier. It will show (B1)(B2) etc. The B stands for band, the number is the band number. To apply these bands, after you have selected them, navigate back by pressing the 3 dots on the top right, keep pressing (back) until you see all options and select (7) apply band configuration. You will get a message saying Apply done. Press the 3 dots again and press back. Now press (2) for WCDMA band preference. Select the bands you need for your carrier, shown above. Press the 3 dots, press back, press apply band, after it says apply done, press back again, press the 3 dots, press end and your done. Insert your sim card, give it awhile for your device to configure and you should now have faster LTE speeds.

Note:

LTE (Internet bands)

WCDMA (Signal bands)

I tried flashing the tmb firmware on my unlocked s9+ from sammy and I lost some things and it didn't give me any bloatware for tmb. Wifi calling is there but disabled and I can't get it to turn on. I got RCS. No caller ID even though I enabled it through shortcut master. What could have happened? The flash didn't fail.

I even tried my old tmobile sim and reflashed it and same results. Not sure why I can't get all the tmobile features to come back and the bloatware. Any thoughts?
