I got the navbar update right after flashing the latest unlocked rom (FULLY UNLOCKED USA VERSION XAA). Can't speak for the US Cellular unlocked rom. Had to do one update before it then the navbar update was the next one. Working perfectly on my AT&T S8+. Pretty awesome to be getting updates directly from Samsung now!
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] JoeJWbD:
Hi Sean,

Thanks for the image, were you able to maintain your data file after the upgrade? is there is home_csc file with the firmware, could you contribute and provide me the Odin version you've used?

Thanks,
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] sean8102:
This is the version of Odin I used.

https://www.androidfilehost.com/?fid=24591023225177749

This is what odin looked like when I flashed.

I did a full reset on the phone first, then put it in download mode and used odin to flash. Got the two system updates second being the navbar after the flash. I haven't tried getting volte, or wifi calling to work by flashing the AT&T CSC yet. Might do that tomorrow.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] JoeJWbD:
Thanks for the prompt response! Do you whether it is mandatory or not to reset the phone before applying the firmware?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] sean8102:
No, not sure if its really needed or not. At the least I would remove your google account, then add it back after flashing. I mainly did a reset because of the tutorial video in the original post suggesting it. Hopefully someone more knowledgeable than me can clear up if its mandatory.

Samsung backup worked well though. I told it to restore all my settings and apps after flashing and my phone is pretty much right back to where it was already.

Upgrade action on Samsung Galaxy S8+ AT&T

I just have updated my S8+ AT&T. AT&T Logo boot-up disappeared so far so good! I have used home_csc to maintain my data, and I had NO data lost! No factory reset needed!!! "Special Thanks for sean8102"

Going to post another review after couple of days

---------- Post added at 10:46 AM ---------- Previous post was at 10:41 AM ----------

Thanks for the information! Just did my upgrade, I haven't received the update immediately. Have you received updates from Samsung immediately after the upgrade? When I click the "Download update manually" bottom it is doing no action, is that regular?

Note: I have used home_CSC and I successfully maintained my data and no loss or errors occurred.

Many thanks,
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] sean8102:
I got a notification for a system update about 10-15 mins after flashing. The first was just a security update. Then after that ~10 mins later I got another notification for a update that contained the nav bar stuff. Currently on build AQG2.

This is what I get when I check for updates manually now. The August security update has not been released yet for the US Unlocked model.

Hello,

I was able to receive the updates after resetting my phone then upgrading to the firmware. Thanks for all your help!
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] blkghost22:
So after flashing all u1 and using hone csc. All of the att feature are there or no?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] sean8102:
I haven't tried that yet. To be honest the AT&T features that aren't here aren't a huge deal to me. But I've seen other posts on here say that they got wifi calling, volte etc back after flashing the AT&T CSC file from one of the AT&T official roms. I don't know if doing so prevents you from getting system updates though.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] blkghost22:
Yea.... ive been trying that but no luck for me lol
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] PinoyKool:
This is amazing! I have a Galaxy S8+ (ATT Originial w/ T-Mobile sim) and just used odin to put the XAA version! Finally getting updates after I fully reset my phone! At first I didn't want to reset my phone but I waited 12 hrs and no update was pushed, so after backing up everything I decided im going for the full reset and TADAH! started to get all the updates (still on going) plus I can finally use Wifi Calling again.

Thanks to everyone that had posted legit information here!
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] sean8102:
Just curious, what did you do to get wifi-calling again. That's the one feature I kind of miss because coverage is poor at my house.

Edit: NM I see you're using T-mobile instead of AT&T.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] PinoyKool:
Steps to activate Wifi Calling:

1) Go to "Phone" app

2) Click the 3 dots on the top right corner

3) Click Settings

4) 10th icon from the top it should Say "Wi-Fi Calling"

hope this helps! i know the usual WiFi calling is attached with the Wifi settings so it took a while before i found it.

P.S. I used "HOME_CSC_OYM_G955U1OYM1AQDC_CL11247461_QB13384431_REV00_user_low_ship_MULTI_CERT.tar" and still did the factory reset and "Wi-Fi Calling" and "Identify Spam Numbers" works great.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] dtomlin:
Does this work on AT&T or only T Mobile?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] PinoyKool:
I have an AT&T phone with a T-Mobile sim card and it works. I'm not sure about the other way around, but i don't see why it shouldn't work because the phone model actually changes from G955U to G955U1.

No! Don't ever do that. SD only
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] Zach5608:
So after flashing this my at&t phone will no longer have a carrier or just switched to an unlocked carrier? Cause my phone is already unlocked but I can't receive regular OTA updates because I'm not connected to at&t towers. So I should be able to receive regular OTA? And is this the GL update?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] rogerandgina:
Does anyone have the csc for at&t they can link for me? I'm on the updated fully unlocked version XAA and I think it comes with the sprint csc.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] XS7V3N:
Hi guys, I am new to this forum. This is my first time flashing. I have an unlocked Sprint Samsung Galaxy S8+, currently using Verizon Sim service and I am currently trying to install the FULLY UNLOCKED USA VERSION XAA firmware (https://redirect.viglink.com/?forma...drive.google.com/file/d/0B7r...ew?usp=sharing) and used Prince's Odin for this package (https://redirect.viglink.com/?forma...ww.androidfilehost.com/?fid=24591023225177749) and I added everything to their respectful sections; used HOME CSC for the CSC section however I keep getting "<OSM> All threads completed. (succeed 0 / failed 1)".

Please see img at (http://imgur.com/a/A3lod) if img isnt working on my post.

Any assistance would be greatly appreciated!
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] monkey39:
Here's another link that provides all of the XAA firmware releases (make sure to choose the S8+ firmware): http://updato.com/firmware-archive-...+S8+&rpp=15&r=XAA&order=date&dir=desc&exact=1

Also, have you tried using the non-HOME CSC? From what I understand, the difference between the HOME and non-HOME CSCs is that the HOME CSC leaves all of your data, while the non-HOME wipes your data along with everything else when you flash. Maybe something in your data is causing the flash to fail? Not sure, but I used the non-HOME CSC when flashing (came from the AT&T branded firmware) - wiped my phone, but flashed fine and received OTA updates. Good luck!

Edit: Also, just a thought, but if it were me, I'd try flashing one of the older versions of the XAA firmware from the link I provided, just to make sure that the OTA updates were working. Up to you, though.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] XS7V3N:
Thank you sir! I figured it out. I didn't have USB Debugging enabled upon installing the firmware and now it successfully installed it. I am able to use my Verizon service with VoLTE calls!

[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] DESERTDART:
I should probably post this in the T-Mobile forum.

I used PrinceComsy Odin and flash passed with no problems.

Phone booted up and setup fine. No T-Mobile apps or anything and no T-Mobile splash screen.

Model shows as G955W now.

Inserted and non-T-mobile sim and got a 'SIM not supported pop up'. Not a prompt for unlock code.

Was able to access APN and could add an APN but would not save. Hit Save and just went to previous screen without saving.

No service with non-T-Mobile sim so appears still locked.

Was trying this to see if I would get an unlock code prompt and maybe have a way to unlock T-Mobile models without the unlocking App.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] jonathan3579:
Well, the good thing is we now know the software conversion is working. It's a shame the SIM card unlock isn't. I guess I'll have to figure if I want to unlock before converting it or not. Either way, thanks for getting back.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] SupacatSF:
So just an update on mine but the Canadian version seems so much smoother and faster than the AT&T version. To answer your question and it makes me super happy to say but Mobile Hotspot and Wi tethering now work without issue! Happy times!:D

Now that we know about the unlock status I wonder if I will be able to unlock once I get a code on the firmware or would I have to flash back to AT&T to unlock her?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] X_Fact0r:

I have not been able to return to 100% stock. There is another thread in T-Mobile section and nobody has been able to go back.

https://xdaforums.com/tmobile-galaxy-s8+/how-to/flash-canadian-firmware-bloat-free-t3602667

I am guessing AT&T would be the same until somebody figures out how to do it.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] thecrunked:
your phone won't let you use a t-mobile sim because it is locked to at&t's network most likely. Just because you can get another network's phone software on your device doesn't mean it will allow you to use that network's sim without being sim unlocked.

Let us know if you are able to flash back to at&t firmware. I would like to flash canadian firmware on my at&t device but only if I can flash back to at&t if i need to.
