If anyone successfully gets the beta flashed to an AT&T device, I would be so grateful if you could document your steps and where you got the proper files. I was all set to do this on Saturday, but the files I downloaded from the Samsung firmware science site were update zips, not Odin files. I can't figure out how to download the ARG8 file from there, because you have to find an earlier version to enable download and I couldn't. I feel like the biggest loser trying to set this up.

Hmmm, in Oreo on my phone the wi-fi calling is on the pull down menu.
[Samsung Galaxy S9  Guides, News, & Discussion] m1batt1:
Look a few posts up and you'll see what I did with my AT&T device. I linked where to find the firmware I used.
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
AT&T's WiFi Calling requires the AT&T firmware. There is no official U1 carrier specific firmware.
[Samsung Galaxy S9  Guides, News, & Discussion] 911jason:
Thank you! I missed your post before... hope they're still accepting beta sign-ups tomorrow morning!
[Samsung Galaxy S9  Guides, News, & Discussion] m1batt1:
The icon is there in the quick settings pull down menu. But it does nothing when pressed. Doesn't matter to me but others were asking.
[Samsung Galaxy S9  Guides, News, & Discussion] 911jason:
Flashed the U1 software you linked to, opened the Samsung+ app that came with it but no beta notification. Uninstalled, went to APK Mirror and downloaded the newest beta version of Samsung+. OneUI Beta notice pops up, register, but the notification to register is still there... 30 mins later, no software update either. Hmmm...
[Samsung Galaxy S9  Guides, News, & Discussion] quikt:
Thanks used this guide to go to the U1 firmware on my USCC S9. The beta registration banner refused to appear no matter what I did in the samsung+ app on the ARIB firmware. After the U1 update finished I checked samsung+ and the banner was present didn't have to do anything with samsung+. I already have zrk9 from the u1 thread so manually flashed. happy camper here
[Samsung Galaxy S9  Guides, News, & Discussion] m1batt1:
I had to reboot a couple times. Plus you have to go into settings>software update and tap to manually check for updates.
[Samsung Galaxy S9  Guides, News, & Discussion] 911jason:
I have rebooted several times, manually checked 20x, but I don't think the registration is actually taking. The beta banner remains there, I don't get a One UI tab in my profile like others have mentioned. I'm not alone in this problem, I have found widespread reports of others having the same issue, but have yet to find a fix. I even tried factory resetting, but same result. Debating whether to just flash the beta from XDA and give up on getting it through OTA, but I would really rather have the OTA so that I can get updates without having to flash every time.

On SM-G960U G960USQS3ARG8, can i flash U1 G960U1UEU3ARJ2 ?

I have an unlocked Verizon s9, SM-G960U build number 3ARG8. I'm on T-mobile sim and i need the wifi calling so I want to flash U1 firmware but i'm not sure which firmware is the correct/compatible one? would anything U1 3xxxx work (such as G960U1UEU3ARJ2) ? and do i need to get the XAA version? Does anyone have the link to download for free?

I've read this whole thread and it seems like bootloader v3 is not a problem anymore. Is this true?

Thank you!
[Samsung Galaxy S9  Guides, News, & Discussion] :
Anyone else try flashing to U1 on patched Odin and come up with a fail error? I'm on BRJ6
[Samsung Galaxy S9  Guides, News, & Discussion] ReapersDeath:
Hey so I have an S9+ in the mail, either AT&T or Verizon, and I plan to go to U1. Do I still need the modded Odin? and what EXACT U1 do i need as I'm seeing multiple now, and the modded odin link in the original post is dead. Could someone link me the correct U1 and correct Odin? I know it cant do it if my bootloader is V3 though. Unless I missed something that changed that?

Edit: I found the ARJ2 U1 to use, but what is this mention of not to use the HOME csc and use OYM csc instead? What is the purpose and difference of this? Also do I have to use some sort of special version of odin still or is normal odin v3.12.3 fine?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
You forgot a one important digit in the firmware. The last 5 characters are important, but omitting the number leaves out the bootloader version, which is really important when trying to flash. You must flash a firmware with the same or a newer bootloader than what your device already has. You do need the modded or patched ODIN to flash to a different firmware. If you use the HOME_CSC, you might end up with no data and possibly no connectivity at all as well as many other potential problems. The OYN CSC wipes the device during flashing, ensuring a smooth bug-free conversion.
[Samsung Galaxy S9  Guides, News, & Discussion] ReapersDeath:
Looks like I downloaded a standard S9 firmware on accident. So;

1: Which S9+ firmware should I download?

2: Do I use Odin3_v3.13.1_3B_PatcheD from https://xdaforums.com/android/software/patched-odin-3-13-1-t3762572 for this?

3: Will the firmware from this thread work? https://xdaforums.com/galaxy-s9-plus/how-to/g965u-g965u1-firmware-links-t3763487 specifically the one from November 1st named "G965U1_RJ2_3_wipe.zip". Or just go with the latest U1 firmware from https://updato.com/firmware-archive...65U1&rpp=15&r=XAA&order=date&dir=desc&exact=1 or another source?

4: If downloading from one of these places, do I need to use region US XAA specifically?

5: They mention getting USERDATA from Samfirm (thread from question #3). What is that about? Is it something I somehow completely missed in this thread?

Sorry for the question vomit.
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
No worries! I would use the latest firmware to save you having to go through an update or two via OTA, unless you want to go that route. The modded or patched ODIN both work fine. U1 non-carrier firmware does not contain a flashable userdata file. When you get to the download page on Updato, if you go that route. Confirm it is XAA again before hitting the download button on the download page. Some say USC for US Cellular.

If you eventually intend on flashing a U firmware after the U1, you want to make sure the userdata comes with the firmware. As much as you can flash any U firmware with any carrier userdata. Some carrier specific firmwares were not released, leaving you on a build that the carrier doesn't provide an update for. You also can't flash a userdata from an earlier factory image without running into some major issues. ATT is a good example of this. You can't (well, you shouldn't) flash the userdata for AT&T on 2ARF4 on a v3 bootloader firmware or newer.
[Samsung Galaxy S9  Guides, News, & Discussion] ReapersDeath:
Honestly? I think I'll go one or two updates behind just to verify OTA is working. On some older phones (S5 on AT&T), I was stuck on wrong carrier firmware and OTAs would not work at all unless on that network. Soo i was required to odin every single update manually.

What are the boxes I need ticked in Odin?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
The default options need to stay the way they are. Nothing needs to be changed in ODIN for flashing options.
[Samsung Galaxy S9  Guides, News, & Discussion] 911jason:
Is it possible to go back to AT&T U firmware after going to U1? Where would I find the Odin files?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
It is, but AT&T current and complete files are harder to find than most other carriers.
[Samsung Galaxy S9  Guides, News, & Discussion] 911jason:
I don't necessarily need it to be current, though, right? Just need to find one with the same bootloader version (3)? Any idea where I could look? I tried searching before posting...
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
Yeah. It would need the same bootloader or newer than your device currently has. The last AT&T complete firmware though that I have seen, was 2ARF4. Maybe check Updato, SamFirm, or Samsung Science Firmware.
[Samsung Galaxy S9  Guides, News, & Discussion] PherChe:

[Samsung Galaxy S9  Guides, News, & Discussion] ReapersDeath:
Sooo everything was working fine. Went from AT&T to the U1 version. Wifi calling works and such, and data and MMS was working, but now its near impossible to receive or send any MMS. and occasionally I get a webpage to load when not on wifi. When I first put in my SIM my phone restarted and I got texts that told me to select some auto configuration thing from my notification area and press install on these two APN settings. Everything worked fine at that point. Buttt I messed with APN settings and had to reset to default, and now they're gone, I don't know exactly what they contained, and I can't figure out a way to get them back. They appeared different from what my carrier provides on their website (ting). and of course whats on their website only has data working occasionally. Is there any way to get these install prompts back? a rep from Ting told me there's no way and they only appear during activation. But this being the community it is, I'm sure someone knows of some dial code. and unlocked is GSM if someone didn't know.

Little extra info, i made sure not to flash the Home version thing in odin. I assumed since it wiped everything, I wouldn't have to factory reset as well.

Edit: So I narrowed down the issue. I CANNOT send or recieve MMS, IF I have wifi calling enabled. If disabled, then I can send and receive MMS. Is there a fix for this?
[Samsung Galaxy S9  Guides, News, & Discussion] Jj icefish:
I recently flashed pie beta ZRK9 for G965U .I wanted to switch to U1 firmware for tethering. Could I Odin back 3ARJ6 then sideload updates from there? Any guidance would be highly appreciated?
[Samsung Galaxy S9  Guides, News, & Discussion] Jj icefish:
Possibly?? ?

Swipe up.

Select Settings.

Select Connections.

Select Mobile networks.

Select Access Point Names.

Select the Menu button.

Select Reset to default.

Select RESET. Your phone will reset to default Internet and MMS settings. MMS problems should be solved at this point.
[Samsung Galaxy S9  Guides, News, & Discussion] ReapersDeath:
Nah that just deletes the APNs i manually put in. Nothing else.

But I did get stuff working. Wifi calling was the culprit. After setting it to prefer cellular when available, wifi if not available, MMS worked again. Wish they'd work at the same time though.
[Samsung Galaxy S9  Guides, News, & Discussion] Jj icefish:
Nice!!!

I've heard Wi-Fi calling doesn't work on the U1 firmware that's great to hear I was wondering does tethering work for you ( mobile hotspot)?
[Samsung Galaxy S9  Guides, News, & Discussion] ReapersDeath:
Unfortunately I don't have any input on the hotspot. My plan has a small amount of data. But the times I did use Wifi calling it was pretty good. But the big thing is carrier compatibility and such.

Im still trying to get edge lighting to work with screen off or always on display. It only works if the screens awake, sooo I'm forced to use glimpse notifications to get it working. If anyone hears of a fix, let me know.

on another note; has anyone heard of a custom infinity wallpaper? As in set what ever image you want as home screen, but keep the AOD and lockscreen effects?
[Samsung Galaxy S9  Guides, News, & Discussion] ZuluAlpha:
The U1 firmware will allow wifi tethering. You are still at the mercy of any data limits from your carrier but tethering will work fine.
[Samsung Galaxy S9  Guides, News, & Discussion] dglaboi:
Any possibility for getting these files from another source? Free version of these sites only allow 2GB download.

Also, I have 2 different S9's. One is a 960U1 and the other is an unlocked AT&T 960U. Everything works fine on both exept on the 960U my banking app keeps crashing upon opening. Same app works fine on mu 960U1. Will flashing the 960U1 on to the 960U remedy this? 960U is on binary 3 right now (with latest ATT updates), will I still be able to flash this U1 firmware?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
It should work fine on both. There isn't a lot of difference between the U and U1 firmware. If it works on the specific U1 your other device has, it should work on your AT&T U model once you flash it to the U1 firmware. You will lose AT&T's WiFi Calling and some other features by flashing to the U1 firmware if you are using that device on AT&T.

You can flash the AT&T U to the U1. You need to make sure that the bootloader of the U1 firmware you are flashing is the same or newer than your device currently has. Use the OYN CSC. Do not use the HOME_CSC when flashing.
[Samsung Galaxy S9  Guides, News, & Discussion] dglaboi:
I actually only want to flash U1 onto the ATT phone to have the banking app work. Even when logging onto banking app via web browser on the phone it gives me some kind of security error. But my ATT phone currently has binary 3 and the U1 firmware presented here has binary 1. Means I can't flash it onto my ATT phone? Or can I download any U1 firmware with binary 3 and flash that on the ATT phone?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
What are the last 5 digits of the build number on your AT&T U and U1 devices? As far as I know, all of the U, U1, and W Note 9 firware are still on the v1 bootloader, but I am on T-Mobile and have only used the TMB U and U1 on my W.
[Samsung Galaxy S9  Guides, News, & Discussion] dglaboi:
960U is on 2AFR4 and 960U1 is on 3ARJ6
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
Ahhh. G960. Simple enough. The AT&T one has the v2 bootloader and the U1 has the v3 bootloader. You can find the U1 your device has and flash that to your AT&T U phone. Once you flash a device to the v3 bootloader though, you won't be able to go back to the 2ARF4. Updato, SamFirm, or Samsung Firmware Science should have the files you need as well as a few places on Android File Hosting. Just make sure the one you download is tagged XAA and not anything else. If you want the same firmware as your U1, look for that build number and XAA on one of the many places to download firmware. Some furmware list USC for U1 but are not the XAA.
[Samsung Galaxy S9  Guides, News, & Discussion] dglaboi:
Can someone upload odin from first post? File has been deleted from that link. Or can I use odin supplied with the download from updato (v 3.12.3)

[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
There is no official T-Mobile U1. The T-Mobile firmware is a U firmware, not a U1 firmware. The U1 firmware works well for T-Mobile though, but you don't get Video Calling and the T-Mobile bloat on the non-carrier XAA U1 firmware. OTA's will come normally on stock official firmware versions.
[Samsung Galaxy S9  Guides, News, & Discussion] Kevotwo:
So u1 isnt a proper firmware with OTAs? Is there a unbranded CSC for 960u?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
The U1 is a proper firmware, but not the one known as the T-Mobile U1. The U1 firmware is similar to the W, just for the US. It is a generic non-branded, non-carrier specific firmware. The T-Mobile U firmware is a specific firmware geared for the best experience according to what T-Mobile thinks their firmware should include..
[Samsung Galaxy S9  Guides, News, & Discussion] dglaboi:
Will my phone be wiped if I flash U1 firmware on 960U?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
If you do it right, then yes.

Hmm...that means I did it right cuz it's wiped. Kinda hoped it wouldn't though...
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
If you flash to the U1 and it doesn't wipe, you will have more than enough issues from it not wiping tp have to do it again properly.
[Samsung Galaxy S9  Guides, News, & Discussion] dglaboi:
No biggie. Made a samsung backup before I flashed anyway. It booted up without errors and now it's restoring data. Hope it will fix my banking app issue.

[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
Converting to the U1 does a little more than just remove carrier related bloat. It will also potentially make some carrier features no longer work, like WiFi Calling.
[Samsung Galaxy S9  Guides, News, & Discussion] MathGuy284:
OK thanks! I think that's a trade-off I'm willing to make. If I decide it's not worth it in the future, could I flash back to Sprint U and reverse the problem?

In the following page https://www.sammobile.com/firmwares/galaxy-s9/SM-G960U1/ , I see so many variants. For a U1 firmware, isn't XAA the only firmware available ? What are the Verizon or T -mobile firmware variants under the U1 firmware section.

Can someone please clarify ? I am confused on the correct firmware to download
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
XAA is the only official stock firmware. The carrier specific U1 firmware do not exist and are combination firmware mixed with carrier firmware CSC's.
[Samsung Galaxy S9  Guides, News, & Discussion] yongendundas:
Hello,

I think this question has been asked before, but I really don't know much about flashing cell phones and need to double check.

Basically, I have S9 from Rogers (SM-G960W, running on G960WVLS3ARL6)

Recently moved to states and using Mint mobile (mvno using T mobile) and noticed my Wi-Fi calling feature isn't working.

On the notification, Wi-Fi calling button is on, and I can't turn it off nor can use it. This feature cannot be found in the setting either.

My plan is to try T mobile firmware, hoping that this feature works (since where I work doesn't have a good signal).

I think I read somewhere that I have to make sure the bootloader version is v1 or something so I can revert back to the original firmware.

My plan is to use flash with G960U1UEU3ARK5 (XAA) first then flash with T mobile one, G960U1UEU3ARK5 (TMB).

Is this the right step to apply T mobile firmware?

Also, worst case scenario, I can revert back to the G960WVLS3ARJ6, right?

Thank you so much!
[Samsung Galaxy S9  Guides, News, & Discussion] m1batt1:
U1 is a non carrier specific unlocked firmware so it probably won't help you at all although you could give it a shot. For instance I have an at&t phone on at&t. When I flashed to the U1 I lost wifi calling.

Your best bet would be to hunt down the U firmware for T-Mobile and see if it works for you.

As for the bootloader version you just need to make sure your current software version and the one you're flashing to is the same. So any firmware you use should have 3xxxx at the end.
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
The U1 has working WiFi Calling for T-Mobile. The only aspects you lose by not flashing the TMB U is T-Mobile's video calling and all of their carrier bloat. U1 also has band 71.

Being on the v1 bootloader, you can move to the v3 bootloader firmware if you decide you want to move to the TMB U. However, you can't go backwards, whichbis why I think you should try the U1 first.

Before flashing, delete the HOME_CSC from the firmware. You have to use the other CSC inclused, which will wipe your device to ensure the conversiin goes well.
