Phone just got delivered now from FedEx. I called Samsung and provided my order number to get the imei number and submitted Friday night to att Device unlock page. Got my unlock code from them this morning in a email approving my request!

So even though i bought the phone from Samsung, (saving an extra $200 for the att variant, att still provided me the unlock code for free. And hey fast at that!

Going to unlock then flash the T-Mobile firmware now. Thanks guys!
[Samsung Galaxy S9+ Guides, News, & Discussion] theredspecial:
What color and model did you get? Everyone with the black S9+ over on slickdeals can't get AT&T to unlock it because the IMEIs aren't in their system yet.
[Samsung Galaxy S9+ Guides, News, & Discussion] dannyHD2:
So phone unlocked successfully, flashed the T-Mobile firmware and Odin said pass, however still att at boot? Do i need to flash unlocked first? I read another post where you needed to do that first.

I flashed regular csx not the home csc. Going to try again using the home csc

Should i fully boot the phone if it falls again and see if i can do oem unlock in Dev options? I wouldn't think that matters if flashing completely fresh firmware. Thanks

I got the coral blue.

So i checked and build number shows latest, however it still has att/att/att and is all att bloat still? Any idea how to get rid of the att and get my tmobile stuff? Phones working great and has lte etc otherwise. But has att boot animation and boat still

Tried flashing just csc and user data but still att bloat. How can i get this converted? Odin passes every time but upon reboot i still get the att stuff..... Using latest patched Odin from first post. Anymore know what's happening here?
[Samsung Galaxy S9+ Guides, News, & Discussion] dannyHD2:
So I was told carrier switching isn't possible with the s9 due to Knox update which is why this hasn't worked for me. Though everything is working except for wifi calling, hd voice and direct video calling, another member has successfully converted his standard att s9 to tmobile by going to unlocked rom first then to tmobile.

My issue is I'm already on bootloader v2so I can't go to unlocked.

Any ideas? All help is appreciated.

Thanks

I have the same kind at@t. I flash the unlock version after I reset and then flash tmb but when I put my sim in tmk pop up because my carrier is metro but try the unlock rc7 with the model odin
[Samsung Galaxy S9+ Guides, News, & Discussion] theredspecial:
I guess that means for now the best bet is just to stay on U1/unlocked because the new V2 bootloader prevents any carrier switching? Am I understanding that right? Presumably because there are no other V2 firmwares?

Hey all. My model is SM-G965U originally on Verizon and recently switched carriers to TMobile and I'm looking to get a 100% TMobile device. I was told in the U1 firmware thread I just need to flash the U1 firmware after a good wipe then flash the TMB U firmware. Is this correct? My current baseband is G965USQS2ARF4. By doing so will the phone be 100% TMobile including the boot animation? Are there any negatives with doing so besides the full wipe? How about OTA's, will they come from TMobile now since I'm now in there network?

---------- Post added at 02:38 AM ---------- Previous post was at 02:26 AM ----------

[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
Will there be any issues with future OTA's? Where will they come from my new Carrier TMobile?
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
OTA will cone from the firmware you have. And you can always use Odin to flash a newer package with HOME CSC and not wipe your device, too. Have fun!
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
Ok cool, thanks for your easy to read and understand instructions. It would be amazing to not have to wipe to get on the TMobile firmware! I definitely need to look into this HOME CSC before I Odin anything.
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
OTA will come from your carrier, assuming you are on the current release prior to that. If you flash another update that your carrier isn't on, you will not get an OTA.

That said, the firmware files work across all U devices. So if there's a more current firmware for another carrier, you can flash it. Just make sure to use the CSC file that doesn't wipe. I've flashed TMobile firmware to my ATT device in the past.

You will need to wipe to switch carriers. You need a clean wipe to the U1, then another wipe to the U version, using the carrier CSC, and then you should be fine.
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
Oh don't get confused. You're going to need to wipe in the steps listed above. Going forward you could always flash to a newer U without a wipe. That's all I meant.
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
Do I just do a factory reset in the settings, or do I need to reset via the Bootloader?
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
Bingo. People worry too much about finding the "right" U. I intentionally flashed the wrong U from U1 and still ended up with the CSC and bloat I wanted. From there, I ran a bunch of update zips intended for a different carrier (nothing got wiped) and kept the right bloat. U is U.

---------- Post added at 10:54 PM ---------- Previous post was at 10:53 PM ----------

When you Odin with a non-HOME CSC it will wipe for you.
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
Cool, thanks for all your help. It's been a year or so since I've flashed anything and a few years since I've rooted anything. If I've learned anything in my past it's to ask as many questions as needed to fully understand, so you don't turn your $1000 phone into a paperweight.
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
Absolutely. Take advantage of the knowledge of lunatics like us who risk life and limb with these things. Lol

Oh BTW - use the 3B patched Odin 3.13.1. Not sure if you knew that part.

Yes, but you need to flash and fully wipe to the U1 firmware first. Once you are on the U1 firmware, which will work fine on T-Mobile. You can then flash to the T-Mobile firmware, if you still wish to.

Im very sorry guys, I have not had a lot of time and just skimmed the last page. Yeah, I know I am breaking like every XDA rule about READ! SEARCH! BLA BLA BLA. So I am lecturing myself so you dont have to....

So here is the deal....

Right now I am getting a push from T-Mo to update G965USQU3ARG7...

Now from what [MENTION=1613431]elli[/MENTION]wgy had explained was the ux is the bootlaoder version.

So to me that is version 3? Am I reading this right?

Also, would this not locke me down to the current carrier firmware until the unlocked version is posted again?

Im just trying to clarify is all....

Thanks!
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
Yes, the last part of the version is <bootloader>xxx#. So for instance there was 1ARB1, version 1 Bl. There was 2ARC6, v2. 3ARG7 is v3 BL.

There is no U1 (non-carrier) v3 rom as of yet. ATT has not gone to a v3 as of yet. When the v2 U1 came out, all US carriers were on v2 for probably a month. If you want to swap carriers, do it before going to v3 or your stuck until the U1 gets a v3 update.
[Samsung Galaxy S9+ Guides, News, & Discussion] Scott:
Thank you, that is the exact info I needed.

Now, I need to figure out which up is the auto-updater and disable it. Or... Shut my phone off within 15 minutes as I have run out of delays and dont want to be locked to carrier firmware. Just to be safe I am even going to odin back to unbranded until v3 is up because I dont ever want to take a chance to be locked to a carrier when I dont need to be.

I have verizon device, flashed to International, then to T-Mo all v2. Im actually kinda shocked its updating but the op did say that for all intent and purposes his drugs, ooops I mean ROMS would make the device 100% legit to whatever carrier he was pushing I mean uploading and sharing to the internet! :p :angel: :eek:

This Op ROCKS! His files are legit and I can vouch for that 100!

If you go to the U1 version, it won't update since there's no update for the U1 yet.

I read somewhere on the forums that the U1 is only getting quarterly updates, so you may not see the U1 update until next month.

Need help flashing ATT based unlocked 965U to TMB to get wifi calling

Guys I'll appreciate the help on this. I have factory unlocked ATT s9+ build/baseband. G965USQS2ARF4. I want to flash Tmobile firmware to get wifi calling working.

Do I have to flash to U1 first then use the Tmobile file from this thread?

Or straight flash the attached file in the beginning of this forum: G965USQU2ARC6.

Also any tips on user data, wiping cache, etc.

Thank you in advance
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
Flash U1's ARF4, then flash U's ARF4. Go ahead and factory reset both times using the normal CSC. Wiping cache will happen as part of the process, but if it makes you feel better you can do it manually once U is back on the phone.
[Samsung Galaxy S9+ Guides, News, & Discussion] Primo13:
Brother thank you for answering quickly my question. Abit new at this and sorry for my ignorance. So I won't need to use this firmware G965USQU2ARC6.

Right. You won't need or want ARC6, because it's really old. Sorry I don't have a link to ARF4 U for TMB handy. I'm sure if you search in the forums here, you'll find it.

My understanding was it wasn't possible on either bootloader but maybe I'm mistaken? Someone said they accomplished the switch with a regular s9 by going to the unlocked rom first so I'm starting to believe is possible but I'm uncertain if it's possible for me at the this point it if i need to wait for some new developments?

Both AT&T and T-Mobile released 2ARC6.

You should be able to wipe data and cache in recovery and set up device with AT&T Sim and get the notification to restart to set up device with carrier settings if not you can flash device without userdata but it as same as wiping data in recovery
[Samsung Galaxy S9+ Guides, News, & Discussion] lethalboy:
Flashed the 2ARC6 file without User data and nothing happened. The tmobile boot logo still there and carrier bloatware. Also, I inserted the att sim when the configuration menu started but nothing happens. Even wiped data and cache in recovery.

Generally the device pops up asking to restart to configure device according to SIM then you get the bloatware and settings.

Sometimes you would have to put in a at&t SIM card or Whatever your carrier Sim first, flash and you should be prompt to restart and it would change.
[Samsung Galaxy S9+ Guides, News, & Discussion] lethalboy:
Tried it also. :/
[Samsung Galaxy S9+ Guides, News, & Discussion] dannyHD2:
I believe you just flashed the same ROM you already have, essentially basically doing a factory reset. The user data is where the carrier software lies. 2arc6 is the latest ROM for US (att and T-Mobile currently running since they updated to v2 bootloader officially) and on bootloader v2. The firmware is technically the same across all carrier branded s9/9+ the user data is where the bloat and specific software is. The csc is where the radio stuff is for the particular carrier (as far as I'm aware). So flashing without user data nothing would change and that wouldn't give you an unlocked firmware because 2arc6 is "U" firmware which means carrier variant. "U1" firmwares are the unlocked unbranded variants. Hopefully that makes sense

---------- Post added at 12:55 PM ---------- Previous post was at 12:46 PM ----------

But you came from an unlocked firmware and bootloader v1.

If you're carrier branded you have to go u1 turned first then to u. If your already on bootloader v2 you can't switch carrier yet. Maybe when the unlocked with v2 bootloader is released it'll work again for people already on v2 but I'm not sure. Hoping so. This is my understanding though.
[Samsung Galaxy S9+ Guides, News, & Discussion] yeltrah123:
Oh ok. I just flashed the T-Mobile carrier firmware on my U1 device since I had network connectivity issues. The ARC6 fixed my issue with that. I didn't buy a carrier S9+ as I noted before, but since my S9+ is now on Bootloader V2, I have to wait till the unlocked S9+ gets its software update on bootloader v2 if I wanted to go back to its software.

It should be possible, because I had once flashed the W firmware on my U model to see the difference and it worked. So it suppose to work vice versa, it would just change your device to XAA I believe since Canadian firmware are XAC by default.
