It's probably carrier related restricted settings then. AT&T SIM's are really bad for locking out features that then appear if you remove the SIM or use one from another carrier.

[Samsung Galaxy S9+ Guides, News, & Discussion] kendrick16:
Like many people in this thread I have an unlocked ATT version running on Verizon with U firmware and Verizon User Data. Everything works except, Visual Voicemail and Video calling. I JUST noticed that when I initially flashed to VZW, I used the RB7 firmware without realizing RBG is the newer one. Checking system updates there are no new updates for me and I am currently on February Patch level. Is there any difference between the RB7 and RBG firmware? Also wanted to confirm that if i flash the User Data to RBG, will it erase everything on my phone?
[Samsung Galaxy S9+ Guides, News, & Discussion] kevindevonwilliams:
Userdata is carrier bloatware, it might wipe device.

If you flash it with home csc then it shouldn't
[Samsung Galaxy S9+ Guides, News, & Discussion] truckilles:
I flashed my AT&T phone to the U1 software, but I'm a little confused about how to flash it to tmobile. I have to grab the U files, and add the userdata for tmobile (or if I wanted to do so, for verizon, etc.) and that would be sufficient?

Thank you.

(edited) Confirmed RBG is newer. Thanks.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
If you haven't already, you will want to factory reset the device to ensure all of the AT&T junk is gone before flashing the T-Mobile firmware. RGB is the one I have saved but I am not sure which is the newer of the two you mentioned. The latest T-Mobile firmware for ODIN is 2ARC6, but it contains the v2 bootloader that essentially locks you on that firmware or newer and T-Mobile pulled that firmware for some reason that has yet to become known.

When flashing, you want to flash the userdata and make sure you flash the CSC_OMC_OYN instead of the HOME_CSC. This will ensure you get the complete conversion to the T-Mobile firmware and minimize the possibilities that you are missing anything, like VoLTE.
[Samsung Galaxy S9+ Guides, News, & Discussion] truckilles:
Yeah so far this phone hasnt been used at all but when I flashed the U firmware after flashing U1, I ended up with the AT&T logo again in boot up so Im re-flashing U1 and will do a factory reset. I also selected the nand erase in options while reflashing to U1 ... which after some google fu seems to have been a mistake on my part... but ill cross all my fingers and toes and hope that doesnt bork this process. The flashing has completed and phone is booting into android and ... glowing samsung logo and startup screen.

Now to do the factory reset, and flash the U software.
[Samsung Galaxy S9+ Guides, News, & Discussion] gamer765:
You do know you have to boot up the phone once after flashing the U1 firmware, with a T-Mobile SIM card inserted in order for the device to change to TMB CSC. Once it detects a TMO SIM while on U1 firmware it will reboot and change CSC. After that, you can flash the TMB G965U Odin firmware. I got a free S9+ from Samsung, Verizon branded and easily changed CSC by flashing to U1 and back to U.
[Samsung Galaxy S9+ Guides, News, & Discussion] truckilles:
Didnt realize about the sim card until your post. I have now successfully flashed the phone to tmobile and so far so good, just need to transfer everything and buy a case.
[Samsung Galaxy S9+ Guides, News, & Discussion] randy_c:
I have a tmobile S9+ and just got it unlock. I flash to U1 firmware per OP with AT&T sim card. Got an update after flashing but my service provider ATT/ATT/TMB? I thought it would be XAA/XAA/TMB?

I am on G965U1UEU1ARBG
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
The only way to get the XAA/XAA/ for the first two is to flash and setup without your SIM inserted. If your SIM is inserted when you flash to U1, it will download the carrier related stuff and settings based on your SIM in the setup process.
[Samsung Galaxy S9+ Guides, News, & Discussion] jmwils3:
so is ARBG the latest update for the unlocked s9+ snapdragon? because they list a much later one, and im a bit confused. im a bit wary of flashing it, as the link seems for the exynos version, not ours

[Samsung Galaxy S9+ Guides, News, & Discussion] dannyHD2:
965f is not your phone! You want to make sure the build is for 965u or u1 which is the unlocked firmware. U/u1 is snapdragon, f is exynos . They have international and us models both listed in that link. I would get whatever you need from xda though and use the modified Odin to flash

if I wanted to flash from the verizon firmware to unlocked what verizon features would I be giving up and what would I be gaining, for example if I leave the sim in while doing the flash will I be able to access the dialer codes or do I need to take the sim out while flashing it and let it restart as a full on unlocked phone and then put the sim back in to have access to those.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Although i ca't speak for the Verizon firmware specifically. When I flashed the W (Canadian firmware) to the U1. The SIM inserted will download what it needs for the carrier of your SIM during the setup process. If you do a full factory wipe before flashing and set the device up without a SIM in it, you won't have any carrier bloat, settings, etc. In your case though, t sounds much simpler because you want to keep your Verizon stuff, just move to the U1. Is that correct?

If so,k, I would suggest just flashing the U1 with the HOME_CSC and not flashing the userdata. This way, you won't lose anything you already have and you will basically have a Verizon U1. After the many times i have flashed my W between what it came with, U1, and TMB U. I found the best chice, at least for me, was U1 with my T-Mobile SIM in during the setup process. Because I switched my SIM to a different carrier though than the phones original W firmware was configured for. I did a full wipe before flashing to make sure I got rid of everything from Telus Canada.
[Samsung Galaxy S9+ Guides, News, & Discussion] silentsten:
Yes, if its possible to do that, that would be preferred, do I need to take the sim out while setting it up as well? I mostly just want to be able to access the dialer codes which the verizon firmware disables. I already have the day one update for verizon, does that impact my ability to go to U1? I saw some people saying that there were some updates that they wouldn't be able to switch with.
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
Yes, they're absolutely cross compatible. It's already been verified - S9 works the same way the S8 did/does. You need to be using latest Odin version, and put the files in the correct spots. I can't guarantee that wifi calling will work though..

[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
Need to use T-Mo USERDATA and wipe before flashing. Also, after it boots back up, watch for the popup prompting to reboot to apply the CSC changes.

SHA256 error means you need to use the special version of Odin that doesn't check SHA
[Samsung Galaxy S9+ Guides, News, & Discussion] BoboBrazil:
After using T-Mo user data there is no prompt to apply changes. It just says applying system update and then goes into the at&t start up screen. Also PrinceComsey doesn't allow you to flash oreo roms successfully. It fails. Is there a version 13.3 odin that has the sha256 check removed? I tried both things you suggested and neither worked

when i restart i get the tmobile spolash screen and it looks like it work but still missing the features. i noticed i never did anything with csc home .. how and where do i flash that? is that the reason its not working properly?
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
The only reason to remove the SIM you are going to use the phone os, is if you literally want to setup everything in your phone manually. APN, IMS, and all of the other key settings related to texting, WiFi Calling, VoLTE, etc. To each their own, but I think the complete manual setup way of doing things is tedious and an annoyance. You also wouldn't be wiping data in your situation so there would be no need to remove the SIM.

I am not familiar with the Verizon firmware but there are some firmwares from carriers that you can't flash to U1 from. T-Mobile and AT&T have moved to the v2 bootloader, which doesn't allow flashing back to firmware with the v1, which the U1 still has. If you go to Settings, About Phone, Software Information, and take a look at your Build Number. The last 5 characters tell you what most reference around here about the firmware. For example, mine is, 1ARBG. The 1 in mine is the bootloader version. If the last 5 characters in your build number starts with a 1, you are fine to flash to U1. If it starts with a 2, then you currently can't flash to the U1 firmware.
[Samsung Galaxy S9+ Guides, News, & Discussion] silentsten:
I'm on 1ARBG which I guess means I can go to U1, where should I get the firmware from, the first post in the thread or is that U1 firmware out of date? Would I have any issues if I wanted to reflash back to the verizon firmware?
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
The U1 firmware is still on the February security patch. Personally, I haven't had much luck with the files the OP posted. I have used files from Bboi86 for all of my recent flashes. The U1 starts with XAA. I don't see the Verizon U firmware in his collection though but the OP or another thread might have one. There was a site that had most firmware variants but I can't recall what it is off hand. I will try to find it though.

Edit: Found it! Updato seems to have it. Their downloads aren't hte fastest but I have used their TMB firmware before without any issue.

Verizon is also still on the February security patch so thats not a big change

Unlocked u1 to Verizon firmware

I have an unlocked gs9+ unlocked (u1), but I want the verizon firmware on my phone. I have the files on my computer, I have Odin, and I have my phone in USB debugging and data download mode. All of that stuff is ready to go, so here is my question. Do I use the CSC file or the CSC HOME file? From what I've gleaned, I am assuming I need to use just the CSC which will reset my phone, but that means I still have the VZW USERDATA... i have no idea had to get that part on my phone, and nobody has thoroughly explained it. If someone could explain it to me, I would be eternally grateful.
[Samsung Galaxy S9+ Guides, News, & Discussion] kevindevonwilliams:
If you want to keep your data intact use the home csc, if you want to completely start fresh then use CSC and flash all files including userdata. With userdata you will have some of Verizon bloatware and software
[Samsung Galaxy S9+ Guides, News, & Discussion] shawnallenxda:
What is the purpose of these?

I bought an unlocked S9 + that was unlocked through Samsung. All I wanted was WIFI calling. This firmware does absolutely nothing to restore that. I have flashed roms and kernels back in the day so very familiar with Odin. I have used stock roms from 2 different threads specific to ATT and WIFI calling cannot be enabled. Talked to two different tech support reps who both confirmed the setting was not there. This is a waste of time and I cannot believe there is no one pissed off like me at ATT and actually created a solution to this. You guys are all awesome as developers but can someone please respond if there is actually a fix for this? If you need more info, please ask.
[Samsung Galaxy S9+ Guides, News, & Discussion] jay2o01:
See the at&t thread for instructions on how to enable wifi calling, essentially you need the at&t 965U firmware, an at&t sim and the imei from an at&t phone to make it happen. Many other users, including myself had the same issue and were able to get it working.
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
I have wifi calling on my S9+ on ATT. I got mine directly through ATT. I've factory reset my phone numerous times and every time I connect to wifi for the first time, it asks if I want to turn on wifi calling. This wasn't even a feature on my v20 I had before the 9+.

Have you tried the Odin files with the ATT user data? From what I've heard from other threads of people trying to get rid of carrier bloat, having the sim card in during setup is what provisions the carrier stuff (apn, wifi calling, visual vm etc). If you haven't tried it yet, do a factory reset, then flash firmware (with ATT user data), and make sure the ATT sim is in when you turn it on for the first setup.

Edit: there are 2 csc files. One will wipe and the other won't. I don't remember which is which offhand, but if you don't use the one that will wipe, it may not download the carrier stuff when setting up. That also could have been the problem.
[Samsung Galaxy S9+ Guides, News, & Discussion] shawnallenxda:
I appreciate that. I have followed the thread and literally read every post. I have done everything outside of calling att with a different imei because I only have iphones in my home being used actively by my kids so I don't have any burner phone with wifi calling capabilities to trick the att system. I have an att sim, the 965u firmware but no alternative imei. I wish att system would let you use the same imei on two numbers but they are smart enough to know what I am doing. Scumbags to say the least. Any other ideas?
[Samsung Galaxy S9+ Guides, News, & Discussion] larainzlo07:
I had wifi calling enabled and came from an iphone. Granted it was an older phone. If you do have an older iphone contact att with your sim in the iphone. Have them reprovision the phone. Enable wifi calling then move your sim back to your S9+. Should work.

[Samsung Galaxy S9+ Guides, News, & Discussion] nugzo:
Wifi calling hasn't worked on unlocked phones on ATT since at least the s7. I've done my share of **** talking.

I dont know of anyone who has been able to get wifi calling working on their unlocked phone (U1) without tricking ATT in to changing your IMEI by using the IMEI from an ATT purchased device that supports wifi calling. The 1 or 2 people that say they have it working on their unlocked s9 without doing the above probably just got lucky with the provisioning on their account (or are not on ATT) Nobody has been able to duplicate their results by flashing any combination of files. Without having IMEI changed, i think you're stuck. The ATT rep asked me if mine was unlocked because those features were not available on unlocked phones. i told her it was an ATT phone i bought from BB and had the ATT logo (on boot). Of course she meant did it have the ATT logo on the back. I told her i read in the forums about the IMEI, She changed my IMEI and all features started working without even a reboot. Of course i was using ATT firmware so the phone was listed as a 965U and not a 965U1 under about phone. Strange thing too is i requested a device unlock for my s8+ about a week ago that i still owe ATT $400 on and they approved it. That was also the phone i used the IMEI from to get my features working. I threw a Verizon sim in the s8+ today and entered the unlock code and the phone worked. Strange how two different devices using the same IMEI would work. Maybe i'll be ok as long as i keep the 8+ off of ATT network.
