Convert Verizon Note 9 to AT&T Note 9 - Samsung Galaxy Note 9 Guides, News, & Discussion

Is it possible to convert via firmware update a Verizon sim unlocked N960U to fully branded AT&T N960U to get wifi calling and all the other branded features from AT&T? Right now I am using AT&T sim but when my device boots up it shows Verizon and all the Verizon stuff is there. Thoughts.....

I believe it is. It's a couple of threads on XDA talking about changing firmwares.

Thanks I figured it out.

Just in case someone stumbles on this thread I will post the solution.
You will need to flash the US Unlocked version of the phone then flash which ever carrier you want.

Just for clarification purposes, are you saying that once you flash the ATT firmware onto a Verizon device that all ATT functions work? Or did you have to also provision the IMEI to achieve this as well.?

sorry for the late reply. But I was able to achieve everything working on my device now. Brief description of what I did to get everything to work:
1. flash unlocked firmware
2. flash att firmware (not unlocked)
3. put sim in another AT&T branded phone
4. Call AT&T have them activate and provision everything on account as normal
5. Put sim in note 9 and activate wifi calling feature
6. DONE you now have a fully fuctional AT&T device, I even got an update from their servers.
I can go into more detail of the steps if needed.

I am looking for the AT&T firmware. I am currently in Kuwait and destroyed my phone. I had to buy an unlocked Note 9 version with the exynos cpu. The problem is I can't WIFI call or use any of the Volte functions my other phone had. Does anyone have the firmware for AT&T? Will that only work with snapdragon? I have already rooted this phone and it is ready to go. I need these functions so I can call back to the States.

Thanks for the quick reply. It looks like I need to wait for Detonator to come out with the AT&T zip. It says coming soon so hopefully soon is in the next couple of weeks. That looks like the best route to go. This is the first phone I have ever rooted. I work with networks and sometimes software kicks me in the butt!

Since this will be the 1st phone you'll have rooted, be aware that, especially with Samsung devices, there's a couple of trade-offs that aren't reversible:
1) Samsung Pay will never work even if you unroot.
2) Knox features (I believe) are also a casualty.
There's an e-fuse, for lack of a better word, that once tripped on Samsung devices, cannot be reset. That's why even if you restore the phone to its original condition, those things will be permanently gone.

Thanks for the info. I read up on all of that and the trade off is worth it. I just need all the Volte features and hopefully the correct frequencies for the U.S. I had a note 3 forever and it got destroyed. I loved that phone. This Note 9 is awesome but without being able to manipulate the IMS settings it is a PITA. I just want to be able to call home from time to time. Emailing the wife is no fun especially with the tech available today. I will keep an eye out for Detonator to provide the AT&T CSCs and all that fun stuff. Then this phone will officially be outstanding. I do have to admit that the rooting process was fun. I am all about modified anything. Stock sucks. LOL

Im not a phone guru like others on here. But from my experience that is all I did. A really important step I didn't mention is leave the cable PLUGGED IN when you flash the unlocked software then the locked software. This caused my device to read the "sim info" and provision its self for ATT and get rid of the verizon stuff and install the ATT stuff. Hope this helps you out.

[Q] Switching to AT&T

Hey,
I just recently moved to the USA and I am trying to set up my Note 3 to work with AT&T but I'm not sure how to do that.
The phone I currently have is a Rogers Galaxy Note 3 N900W8 (Already knox 0x1), and I'm curious what I need to do to make it work with my AT&T sim card.
I was hoping to stick to ViSiOn-X but from what I can see that is not available for AT&T, so I'll probably just stick with the stock ROM, whichever that is.
Though, I do still have a phone plan in Canada and would like to switch between the sim cards so that I can check my voicemail if at all possible.
Is it possible to set up my phone to work with both Rogers Canada and AT&T USA? Or am I required to purchase a factory unlocked phone to do that?
If it is possible, how?

You need a factory unlock so you can switch carriers now as for the rom I'm not sure if the rom will work on AT&T, you should check the rom forum an see if other AT&T users used it an if don't already know the Model for AT&T is SM-N900A, also you could always try the rom once you get an sim unlock, an try it with that rom but if it don't work flash a rom that you kno will work

Ive got my phone unlocked now, but I think there may be some issues with the ROM. When I first unlocked it I was getting the 4G connection to AT&T. Now I just have the regular phone connection, no 4G. Data is on.

T-Mobile stock firmware on SM-G920T factory unlocked version

I recently purchased the G920T factory unlocked version on eBay, is it safe to Odin any T-Mobile stock firmware, any info will be appreciated, thanks in advance.
Once you above a certain firmware you can't go back. What firmware you currently on?
It is currently on G920TUEU3COK1 can I Odin to the latest T-Mobile G920TUVS3DOJC I understand that I can't go back but is it safe and will it function normally, thanks for the reply.
i have this same question because from what ive read 3COK1 is for Cellular South (aka C Spire). while the 3DOJC is for Tmobile, both under the G920t firmware. are you also on tmobile network with this phone?
What are the benefits of flashing T-Mobile firmware on the USA factory unlocked phone? I have this phone on T-Mobile and wifi calling works. I also get great reception. I assume this phone will get Marshmallow months before T-Mobile releases their build

Are you getting LTE on it.
So I flashed the C Spire firmware and it asked for an unlock code. I flashed back to the original tmobile firmware and it is still locked although it was unlocked before, but the device unlock app says its ineligible for unlock now.
Anybody else encountered this?
Call t mobile customer service and ask them. They can adjust their servers and then the unlock app will work.

I'd advise that you dont.
To unlock it I had to flash back to the original tmobile rom. From the tmobile rom, the device unlock app failed in different ways.
After i called tmobile over and over I got it unlocked (like 2 hours of calling).
Hurts my heart to see all the tmobile bloat, especially when i dont even live in the US, but at least my phone works

Stock 960U firmware for ATT, VZW, TMO, SPR, USC AND 960U1 XAA

I uploaded most of the stock SM-N960U firmware below to my google drive since Sammobile is slow going. It includes ATT, Verizon, T-Mobile, Sprint, and US Cellular. Also, the unlocked SM-N960U1 XAA firmware.
SM-N960U ATT
SM-N960U VZW
SM-N960U TMO
SM-N960U SPR
SM-N960U USC

Yes that's why. Starting with Oreo on the Note 8 (and some late Nougat builds on the S8/+) Samsung software will automatically switch carrier versions to match your SIM card. Manually flashing carrier firmware when changing SIMs is no longer necessary.

Are you referring to carrier rebranding that the note 8 "U" models used to do? If so , I don't believe the note 9 "U" models are so far capable of this.
With rebranding/brandswitching I'm referring to when I switched my Note 8 sim card from a T-Mobile to Sprint SIM then the device would change the device into a completely Sprint branded Note 8 , Inc bootup logo etc.

Hey, Limey! Yeah that's what I'm referring to. That's weird the Note 9 can't do that. I always thought it was cool to pop my ATT SIM in my Note 8 and watch it completely change to an ATT device, then back again.
I'm looking for a Note 9 now to possibly upgrade. Can we not do carrier switching at all now? I know a Verizon or ATT Note 9 would work on TMo, but I don't want to see the VZW or ATT splash screens. I guess I could just flash the U1 firmware.

Flashing the U1 firmware works. I did this with my Verizon Note 9 and it changed everything to the U1 including the model number. I'm pretty sure you can flash any carriers firmware as well.

Hey buddy, good to see you on here. Hopefully see more of you soon when you get the Note 9.
I also found it weird that the unlocked carrier branded Note 9's didn't have this feature, going by the S9 I don't think they do that either. I think it was just the note 8 and s8, but I could be wrong that had that capability.
What region/type note 9 are you looking at buying ? Cheers.

Yes correct , flashing works. But on the Note 8 carrier branded SIM unlocked versions one could switch SIM cards from different USA carriers and the device would automatically reconfigure rebrand itself to the inserted SIM card carrier firmware. Was a wonderful thing

Yes , that made carrier switching much easier than having to flash the firmware and possibly resetting.

I actually just bought a nearly new, mint Verizon Note 9 off eBay. Guy listed it for $690, and I had $63 in eBay bucks, so it was a no brainer. Well, as long as it's actually mint, paid off, and clean IMEI as described. I'll find out when it gets here.
I flash the U1 firmware, stick my T-Mo SIM in it, then flash the T-Mo firmware and see what happens. God, I miss the automatic carrier switching.

Sorry for the novice question. I've been out of the world of rooting since I had my Note 5 so I'm kinda starting completely over.
I have an unlocked Note9 with the Snapdragon processor and I'm trying to get wifi calling to work on AT&T. From what I gather, AT&T has blocked that on unlocked phones.
Can anyone tell me if I root the phone and load the SM-N960U ATT firmware from above, will I then be able to use wifi calling? It should basically be a completely rebranded AT&T phone at that point, correct?
Another question related to that... Even though I would have the AT&T Firmware on it, I assume I would NOT get OTA updates from AT&T because the phone is rooted, correct?
Thanks for your time and putting up with this "noob's" questions.
i have the same question

Another question related to that... Even though I would have the AT&T Firmware on it, I assume I would NOT get OTA updates from AT&T because the phone is rooted, correct?
Thanks for your time and putting up with this "noob's" questions.

The US version of the phone has no root.
To change and successfully run from one carrier to the other.
1. Flash U1 ROM with sim card of desired carrier
2. Boot up
3.Flash U ROM of the carrier with userdata in the patched odin
That should make it carrier branded
Can I flash the unlocked version from sd card

no you need a computer
I ran into an issue, i got an ATT SM-N9650U which i purchased so its unlocked, but i want to get rid of all this carrier brand and leave my phone completely carrierless, using U1 firmware when i try to flash i get an error, im trying to flash on a new phone with an original cable, ran into admin mode and also tried on both my pc and my laptop without any success, when i hit start on Odin this appears:
<ID:0/009> File analysis..
<ID:0/009> SetupConnection..
<OSM> All threads completed. (succeed 0 / failed 1)

Can I flash Sprint S10+ to look like unlocked version direct from Samsung?

My dilemma. I purchased a S10+ unlocked from Samsung.com and I use it on the Sprint network. I am having data/cell problems like a lot of others are having. Samsung refuses to fix or replace the phone saying it will be fixed with an update. Sprint says they will replace my phone but it would be the Sprint version. If i do the replacement with Sprint can I later flash the U1 making it act like the unlocked version? No carrier bloat?

Service issues with T Mobile and Sprint are known. Neither have been addressed since release. As for your question, yes, it's possible to convert a U SPR to U1 XAA (and vice versa). You will lose data following the use of non Home CSCs in Odin.
You can technically preserve all data, but it's strongly recommended to follow the steps as they're written.
E: firmware is here https://forum.xda-developers.com/galaxy-s10/how-to/s10e-g973u-g973u1-firmware-links-t3905852
You can also use Samfirm and other places.

No prob. I converted my Tmobile N8 950U to U1. Bought an unlocked U1 S10+ so no need this time around.
I have the sprint variant as well of the s10. Would flashing this sim unlock the phone?
No

Nope. You're only changing the firmware on the phone, you're not unlocking anything.

Unlocked vs AT&T branded, will unlocked version support AT&T WiFi calling

With other S series devices there was a U and U1 model and only the U model supported AT&T WiFi calling.
Do we know yet if the same will be true of the S20 FE?
(As explained in other threads, with other S series devices it was the same hardware just different firmware and you can flash the phone to switch from one to the other)
I have the unlocked model from Best Buy and I'm on At&t. I don't see any option for wifi calling.
The Wi-Fi Calling app is installed on the phone, you can see the app in the list of system apps. I tried accessing it using Nova Activities & making a widget shortcut on the home screen but when I click on the icon it says permission denied. So it's there but Samsung / AT&T aren't letting us use it. I found this document, (I can't post the link since i'm a new user) google "service capabilities unlocked device att", which shows that previous unlocked Samsung Variants did not have Wi-fi calling on AT&T. Maybe there is a way to bypass the permission denied or access it? It's a deal breaker for me and I'll be returning the phone if it doesn't support Wi-Fi calling. I just signed up for a year of AT&T prepaid.
I was able to convert my Unlocked Model Firmware to the AT&T Firmware and now Wi-Fi Calling is enabled. It came with some other AT&T apps (Bloatware) but I don't mind since Wi-Fi Calling is a major plus for me. It's essentially an AT&T Branded Phone now except it has all the bands that the Unlocked version has.
Would you please care to elaborate how you did it? I’ve tried the typical Odin process with no success

Sure, First make sure you have the Samsung USB Drivers installed. You can find it on the support page of the S20 FE. I Downloaded Frija 1.4.2 in order to get the latest Firmware. Model "SM-G781U", CSC "TMB" for the U.S Version. As I understand the Carrier versions are all the same and will load up the correct one based on the sim card you have in your device. I downloaded Odin 3.14.4. Unzipped and placed the correct files into Odin, I did the non Home CSC file and left USERDATA blank because Samsung switches the version based on your sim card. Put your phone in Download mode. I got an error the first time but switched to a different USB and it flashed it to the AT&T version.
Thank you!

I've done this process numerous times (with success) but with this S20 FE from TMO the XAA firmware does not prompt me to reboot on SIM change (carrier change). I've found that this process works flawlessly to change the CSC:
Go to "Settings" then "About phone". Write down your IMEI Number. Open dialer and enter *#272*IMEInumber# (In the thread replace IMEInumber with your actual IMEI Number). Press dial, you should see a screen with the list of available CSC codes for your device. Select the CSC that you want and tap the Install option.
In my case, this won't wipe the data on the phone, your experience may vary.
Another note: if you're using the "U" firmware, a CSC change will prompt the installation of carrier bloatware upon reboot. If the "U1" version of the firmware is used, the carrier changes but without the added bloatware.

where did you download the roms from is it the same model as the regular s20 unlocked ones or ?
Can someone confirm the *#272*IMEInumber# does, indeed, work on the unlocked S20 FE sold in US? What CSCs are available? Can you really switch between them without losing data? Do any of the available CSCs have eSIM enabled? What about native call recording? Which ones?

No, use Frija 1.4.2. It has the lastest Firmware for the S20 FE.
I'm using an AT&T MVNO and I am able to get wifi calling. I popped my sim in during the setup process and it rebooted a few times. No bloatware or anything. I think as long as it's the first sim in the phone, it should do the trick.

You know what I needed to type to get unlocked U.S XAA? Been searching and no luck.

I have the SM-G781U1. Tried the *#272*IMEInumber# trick but after I change the CSC to XAA, the phone reboots twice and goes back to previous CSC (ATT) with no Wi-Fi calling. Also, cannot find any firmware for this model on Frija. What is the difference with the SM-G781U?

Last I checked there's none at&t firmware. You should wait for now. Terrible, At&t still don't play nice with unlocked phone.

So you were able to convert firmware on G781U1 to AT&T G781U for Wifi Calling? In regards to bands, if you switched firmware from AT&T to unlocked, shouldn't it also enable all the unlocked model bands?

I confirm what posted by Donatelloj. Starting from SM-G781U1, I installed firmware for SM-G781U (CSC TMB) with no USERDATA and Wi-Fi calling is working now! I had an issue with the fingerprint sensor not working but after 2 reboots everything looks fine. Now having troubles syncing Gallery with OneDrive but I believe this is a different story.
I've just installed unbranded Android 11 (G781U1UES1CUA2) on US unlocked SM-G781U1 and ATT Wi-Fi calling is working. No need for branded firmware anymore.
