Oreo has been out for a few weeks on U1. (I know it has been out for awhile on U, just commenting on official U1)

I actually just carrier switched from U firmware on SPR to XAS. I purposely flashed Nougat to confirm OTA but now on Oreo CRB9 official. Was hoping to find some flashable updates as Samsung seems slow at releasing unbranded firmware updates.

Moving My T-Mobile 955U to Verizon

Hi All,

We just moved to a rural area where Verizon is the clear favorite due to its signal.

I have read through much of the thread but the information appears to be pre-oreo.

My Phone is a T-Mobile SM955U that is sim unlocked.

I've used odin many times, so no questions there.

I'm just trying to figure out which firmware to flash.

Looking at Sammobile https://www.sammobile.com/firmwares/galaxy-s8-plus/SM-G955U1/ is it the USA version, or shoudl I be flashing the Verizon software? I'm thinking I should flash the Verizon firmware. What do you think?

Thanks in advance!

[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] TheTECHIE:
The link doesnt work
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] SupacatSF:
I never thought it would sim unlock and understand the Sim lock. What I was looking for was the prompt when you put in the unlock code after popping in another SIM. I know I need to use an unlock service but there is no prompt to enter unlock code.

I am not looking to go back to AT&T right now as everything is setup perfect for me. Hopefully, someone else can chime in who tries and needs it more than I do. For anyone SIM locked on AT&T, when you put in another carrier sim does it ask for unlock code or says invalid sim like I am seeing in the Canadian firmware?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] guyd:
I unlocked my SIM by using the dialer code #7465625*638*# which prompted me for the unlock code
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] BigHussle:
You can go back using the latest version of Odin 3.12.5 or 7
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] thecrunked:
is one of those versions better/more successful than the other?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] BigHussle:
No I don't think the 7 is easy to find because it may be still in beta. But you have to use all the slots
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] DESERTDART:
It doesn't work

I have both versions. of ODIN. Flashing back the stock firmware does not put back the carrier bloatware and apps.

It passes the flash and I used the Userdata file.

Flashed to get back to T-Mobile and still no T-Mobile Apps or splash screen and it shows model as XAA/XAA/TMB.

And I manually installed the T-Mobile unlock App but get an error when running it "This app is not compatible with this device". So now when the device is eligible for unlock, I won't be able to unless there is a way back to 100% T-Mobile.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] thecrunked:
maybe try flashing to us cellular or at&t firmware and if the firmware actually fully flashes onto the phone you can try flashing tmobile after and see if you can get back to normal

edit: just want to confirm. you started with official tmobile phone and flashed unlocked canadian and are now stuck there correct?

i'm curious to see if you can start with official at&t firmware, flash canadian, and flash back to at&t but for whatever reason the tmobile phones can't do that
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] DESERTDART:
I have tried US Cellular, AT&T, Verizon and T-Mobile. There are other threads about this in the T-Mobile section also. The Flash completes but it doesn't put the phone back to 100% stock. It stays stuck on XAA/XAA/Whatever carrier you flash. No carrier apps or bloatware.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] SupacatSF:
You sir are the man! Thank you as that worked so now I just got to purchase an unlock code. Many thanks!:good:
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] DESERTDART:

[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] thecrunked:
might want to redownload the firmware, sounds more like a corrupt file to me. the poster who wasn't able to flash back from whatever he flashed to tmob said the flash was successful but it didn't actually return the phone to tmobile stock

[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] AndroiderM:
As of right now there is no way to go back to 100% Verizon stock, same for T-Mobile, Sprint, and the jury is still out for AT&T but I suspect the same. You can reflash Verizon firmware but your phone will still read XAC/XAC/VRZ or XAA/XAA/VRZ. I would wait for the US unlocked firmware to release or for a fix to get back to stock if ever needed.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] eddyo1993:

Is this the correct firmware for US unlocked? Had issues downloading from drive so went updato. Just wanted to verify before I flash. Do you know if spotify is baked into this firmware? That's a deal breaker for me cause I use a hacked version of spotify daily lol I can't go back to commercials.

Will this XAA my device across the board or just first 2 slots? Do I need to flash ATT CSC over this or before this. Sorry tons of questions just wanna make sure I do everything correctly.

My phone is already SIM unlocked and my goal is to make it a fully unlocked US variant that receives OTAs directly from Samsung.

My understanding, please correct me if I'm wrong is to

Remove all Google accounts

Factory reset

Boot download

Flash unlocked US firmware XAA

Set up phone as usual

Do I need to flash ATT CSC, enable all bands, set APNs, and or any other steps? Any guidance is greatly appeciated. Paid full retail for my AT&T S8+ and would hate to soft or hard brick it.

[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] Quickvic30:
There's att firmware 5-6 threads down from this one......

To get all the att features working you have to flash user data in the UMS slot after installing the U1 firmware. After you install the U1 firmware set up then phone then reboot back into DL mode and flash att user data. That's​ what I did and have volte, video calling, wifi calling and tethering also works on ATT unlimited plan. Phone is still 955U1 model but has all the att features. You can also delete/uninstall all the Google bloat and only one att app appears after flashing and you can delete that also.

There are some guides in the regular s8 no carrier forum. It's really easy though. What I did.

Flash U1 firmware BL/AP/CP/Regular csc NOT home CSC, will wipe data so beware of that.

Once phone passes and reboots just go through set-up and don't enter any of you accounts, just keep hitting skip. Once your to the home screen reboot DL mode. flash ATT user data in the UMS slot and you'll have all the ATT features with a 955U1 model phone still.

Matching makes sense, especially if you're not changing carriers. Just seeing a lot of contradicting info in different threads. If we want to go back to the complete AT&T branded G955U, would we just flash the QDE software in Odin?

I know this might sound kind of stupid, but my s7e I never flashed and the last samsung I had before that was the S2. Been with LG for a while.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] Quickvic30:
I would assume so yes, haven't tried cause I'm messing around trying to root this pile, been at it for days, still no luck [emoji25]

I bet if you flashed user data in the AP slot it would more than likely bring it to all at, that's just an educated guess though but a pretty darn good one at that. I've flashed just about everything there is to flash lol

Never flashed anything on the S7 edge!? That's amazing, you have strong will power lol, I would never be able to do that.
