most likely not, you have a locked bootloader

Any way to unlock the bootloader?

no devices from ATT are basically big locks

I called tmobile and ask them if they could flash my unlocked att samsung galaxy note 4 to the tmobile software. They said that they could not and i have to call samsung. I called samsung and spoke to level 2 tech support. Level 2 told me that i can go to a bestbuy store and visit the samsung shop inside of bestbuy and they can reflash the software. I ask the level 2 person again that i did not want a reflash of att software but i wanted the att software fully removed and tmobile samsung note 4 software flashed. He said again that it could be done because the att and tmobile versions of the phone are same hardware wise only thing that is different is the software. I can not say for sure of this works because i have not gone to bestbuy yet to have it done. I wanted to see first what other people here thought about what i was told. Then i would go and get it reflashed.

Doesn't work that way.
The only Note I ever seen that was crossed flash was the OG AT&T Note 1. There is a literal T-Mobile Rom for the AT&T Note 1. It even lets you use a T-Mobile sim on a sim-locked AT&T Note 1. Problem is it's buggy. and sometimes you would lose a signal, or get random freezes and reboots.
For your AT&T Note 4 to work in that fashion, they would have to make a TouchWiz rom from a stock T-Mobile Note 4 ported to work on your phone. A straight flash or even using ODIN to put the T-Mobile Note 4 Rom to your AT&T Note 4 will brick your phone. Modification would have to be made. Don't worry about the locked bootloader as with previous AT&T Samsung phones flashing TouchWiz roms can be done, you just cant flash Cyanogenmod or ASOP roms that's all.

Is not the tmobile software touchwiz based? I thought it was.

It is, but they can't completely strip your phone of the AT&T software. and dump T-Mobile on there. Someone has to create a modified ROM for it to work on your phone.

Why?? Can they not flash baseband and modem and rom to my phone without brinking the phone?

Hey, man from 2017 here.
I stumbled upon this post while I was trying to figure out what the hell I just did to my phone. I've spent the last 4 hour of my life trying to unbrick my Galaxy S7 Edge; just installing firmware after firmware hoping that it would post with Odin. Right when I was about to give up I noticed something happen on Odin that I had never seen before: a green box that said "pass!" rather than "abort!". I looked at my phone to see if it had actually made it out of this boot loop that I had been dealing with for the last four hours, and to my surprise I saw a T-Mobile logo. This stood out to me because the Galaxy S7 Edge that I own is an AT&T device. I don't have the energy to figure out who I unknowingly managed to bypass the Qualcomm Snapdragon's locked boot loader, I just wanted to share my discovery with anyone who was curious. If anyone is wondering: the device is running perfectly with no lag, I now have all the T-Mobile bloatware (lucky me), I can still connect to AT&T cell towers.
One final note that I feel like I should mention: When I initially bricked my Samsung, it was because I forgot to turn on OEM Unlock and turn off SafeBoot. It's puzzling to me how I was able to unknowingly do something that few have ever accomplished and doing so with all of Samsung's security measures still in place.
Update: Wanted to also mention that knox never got tripped however so far Samsung Pay is not useable.

I think you can cross flash with certain phones and carriers. I flashed tmobile galaxy s7 software onto my girlfriends sprint s7 and it works perfectly gets even better coverage then my tmobile note 4.The phone jst has to be unlocked by the carrier that it!

Wait.....so your saying you took full tmobile (gsm) software and flashed it to a sprint (cdma) device?....and it works perfectly?...and by flashing you don't mean swapping of motherboards?.... Common mistake I'm sure

Exynos version on Verizon

Anyone know if the exynos version would work on verizon? I assume that that it would but the 1x and 3g would not. lol, i would be ok with that if i also go root and TWRP.
My follow up question is where could we order it? It would be nice to get it right from samsung, but i don't see that option.

I have the same question

i think this is the place to buy it. Since they will open it up and use one of their sims to make 5 minutes of calls before sending it to us, so it doesn't lock up once we get it.
Has anyone used 4g exclusively on verizon, what are the drawbacks?

I know where to buy it here in the US. I could actually buy it today. Just want to know if it will work on Verizon

I dont think you will be able to use it to make phone calls or msg because verizon use a CDMA network for this and the exynos version doesnt have this. Just my guess.

Samsung's soc never supports cdma (big Q owns the patents) so that's why the rest of the world who aren't on cdma gets the exynos versions

That's not true at all, my Galaxy Tab S2 is an Exynos and runs on Verizon LTE., and the galaxy S6 was an Exynos 7420 on Verizon.

Oh I stand corrected. I knew the tablets were supported but figured since you don't make calls from them, it wouldn't need cdma. In either case, unless it's made for Verizon, the exynos versions won't natively support Verizon.

The FCC filing shows it support the Verizon LTE bands, but no CDMA bands.
It would probably work for data but I am not sure if it would work for calls, unless they implement VOLTE on the international version for Verizon.

Guys it's best to wait for the North American unlocked version (Qualcomm chip) to become available in a couple of weeks or so.
It will definitely work on both Verizon and Sprint and their MVNOs.
I can see bhphotovideo taking preorders for it already, and the page is setup on bestbuy. This is the S8 version I'm gonna go for. Downside is it will cost you a little more, but it is worth it to me to know I can use it on all US carriers.
Edit: looks like bhphoto added the model numbers for their preorders as "SM-G950F" and "SM-G955F", which is the same as the European/global GSM version. So that is Exynos chipset powered, and it's a no go for CDMA guys.
The plus on this model is it gets the software updates more quickly than the US unlocked model. (This is still speculation based on Samsung not updating SM-G930U to Android 7 for months while the SM-G930F and the US carrier models already received their updates.)

unlocked as in unlocked BOOTLOADER? Or just for use on any carrier?

Unlocked as in "unlocked for all carriers" (or "sim free" is what Samsung UK calls their SM-G95*F versions). But I wouldn't be surprised if the bootloader is also unlocked.
My guess, even with the unlocked (unencrypted) bootloader, is once you flash a custom ROM/recovery it will still trip the Samsung Knox binary counter and void the warranty. This is just speculation based on Samsung's devices in the past. We have to wait until someone gets their hand on the US unlocked version.

Sim unlocked at best buy will be out may 9th priced at 725/825

i buy international versions all the time...
don't listen to all these people who just make things up but never used it.
supported bands according to this site just an example:
http://www.china-prices.com/phone/bands/7922/samsung-galaxy-s8-exynos
I have the exynos s7 i bought from B&H in US. on verizon CDMA won't connect, but if you are in a region with VOLTE and you don't travel within US, it should be fine.
all the international versions have much better support if you are on ATT/Tmobile where GSM is the "3g/crippled 4g" I left verizon for Tmobile just to get better support for Exynos.
now... i didn't check validity of the site above, but it gives u an idea. i just wanted to chime in.
Exynos has much better power management IMO. my wife's phone is S7 tmobile variant, and when i was using s7 Exynos, my battery life was BETTER AND i use the phone way more than her throughout the day.
going to, i actually bought s8 TMobile this time... just so i can use samsung pay... samsung pay will work if you modify the CSC and install spay/framework, but guess i'm getting old and getting lazy
exynos will likely get rooted FIRST, and the first root type will likely trip Knox, and without Knox, no samsung pay...
TLDR. Exynos will work on vzw but not all the bands. if you think it's too risky, don't get it.
2 upsides that actually matter IMO when it comes to Exynos versions.
1. less bloat, I say less, because Exynos versions come with all kinds of CSCs from all over the world. and depending on where it came from... you'll see it installing regional specific apps on your initial boot. 1 year i had a phone with Arab CSC and it installed bunch of apps made for Arabs... on another phone i had a UK CSC and it installed all kinds of UK news apps.
2. better battery
3. faster updates from sammobile

I read it I just think its a dumb GSM phone for people that have a dumb CDMA phone provider. LTE only is not a solution Verizon people simply need Verizon phones. Just like Sprint people need Sprint phones. Getting international GSM phones for use on CDMA service providers is stupid. Thats one reason CDMA is crap compared to GSM. Unlocked phones like some apple and moto and rare samsung are the best solution. Best Buy will have the unlocked snapdragon available in 2 weeks for $725/$825

You dont need regular calls? You are going LTE only and hoping you dont miss any calls? If you are using hangouts for calls and don't need cellular phone calls then go get one. Ebay, amazon, they have them for sale, forget warranty unless you want a huge hassle.

I understand everything. I was wondering who has done it in the past. Everyone in my company with the latest update from Verizon has seen their CDMA coverage disappear. Where they once had CDMA service, they now have none. Verizon seem to really be pushing the VoLTE. I've had phones where i have disabled all non 4g bands, because i didn't like it switching, and it actually worked better for me. The main reason i ask is because the international version has root and TWRP. Hopefully the US version will get root, but i don't think we'll every get an unlocked bootloader. The verizon version is already sim unlocked, so i'm not looking for more sim unlocked phones that don't have root.

ATT Note 9 unlocked Can it run on Verizon if so how?

I have an ATT phone inbound that is unlocked by ATT however the owner says he tried his Verizon sim and it did not. work.
Can I flash unlocked stock firmware and have it work with Verizon sim or are they two different models with different internals.
If it will work can someone point me in the direction of the firmware that will work Please.

In the title, you say note 9, this forum is for note 8, I think it will more useful for you to look over there

Let me tell you, you've come to the right place. As you can tell in the subforum title, this is clearly the Note 9 forum. You've done well to come ask your question here.
More seriously, if I'm not mistaken, from what I've read around these parts of town, flashing the unlocked firmware should allow you to use a different carrier SIM. It's my understanding that most carriers use the same model, safe for maybe one, but I can't recall which one that is, now, since I'm not American and I don't really pay attention to those things.
I believe the Note 9 models will work the same as the Note 8 and previous models, in that regard. You can't really lose or break anything by flashing the unlocked firmware. Either it'll work with Verizon or it won't. Might as well give it a try.

It will not work 2 different kind of cell service. Tmoblie and ATT can work together and Sprint and Verizon can work together. One is CDMA and one is GSM

Question about possible SIM locked SM-G973U

So, I have been trying to get a Verizon Galaxy S10 working on straight talk.
I have a previous S8 that works just fine and even says "Tracfone" upon reboot once activated.
The s10 was sent via the Samsung B2B program and I put in a Verizon sim and it activated right away on a line that did not have a contract at all on a business account.
I went ahead and deactivated the line and tried the Straight Talk sim in the S10 and keep getting a message that states "Sorry, your device cannot be activated on another carrier right now."
Have tried texting "APN" to 611611 and calling straight talk multiple times. Finally, I managed to call up Verizon and they stated there was a spot that said "Locked" on their side and spoke to a tier 2 rep and they mentioned that they "unlocked" my device and it should be fine. The phone still keeps showing the same message so i tried popping in an active Verizon SIM thinking that would help and it is still doing it.
Funny thing is everything appears to work for a minute with talk, text, and data then this message keeps appearing making me think the device is still locked.
Anyone else have a similar issue trying to get straight talk working on their S10?

I guess at this point I am just curious if this is typical behavior of a device being sim locked to this specific carrier. I was under the impression that you usually get an option to enter a code to try and unlock the sim is why I am asking.

The S10's in general are not locked unless it was pre-paid. You said you got yours through the B2B channel? I have an S10 as well and I am running a Metro PCS SIM as we speak. I believe there is a condition in which the device can't have a new SIM inserted, Ill ask around and see if I can recall what that is.
---------- Post added at 04:13 AM ---------- Previous post was at 03:57 AM ----------
OK, official answer is its SIM locked for 90 days. You have that issue because Straight Talk is a wholesaler of VZW services. If you use a different provider, such as T-Mobile, AT&T, etc. you would probably not have that issue.

This is what I was afraid of.
The tier 2 Verizon rep seemed more than helpful and said they definitely "unlocked" on his side.
At this point I will simply wait the 90 days and try again since I don't see a work around making its way out before then.
The Samsung B2B in my case is because my work is a Samsung house with about 10k smartphones and tablets and it offers me 1 free Verizon Samsung device for testing/review/company approval.
This device is NOT tied to our Verizon account nor Knox account and is usually sent directly from Samsung.
I have gotten Google devices the same way. This s10 appears to be the first one that has given me this issue as my note9, S9+, S9, s8+, and her current s8 do not do this at all and they were all b2b devices as well.

Sorry for the confusion on this. I think I have the right answer finally. I had to consult with a few folks that would know for sure. So, here's the reality. Verizon does not want you to be able to take your VZW LTE device to another carrier, however they can't legally SIM lock them (at least not for that purpose). That was a result of some agreements that were made with the FCC during a previous merger. So, they DO SIM lock them, ironically, but they basically label it as fraud prevention. So, the way they get around it is that they SIM lock the device for the first 24 hours after activation, however, you can call and have it unlocked. The official answer is that it is in fact SIM locked, and you should be able to call them and have it unlocked.

In case anyone wanted a follow up on whether or not Verizon auto unlocks these after 30 or 60 days the answer appears to be a big fat NO.
This S10 still appears locked and cannot be used with any other sim card than Verizon.

When you get a phone through Samsung for a particular carrier you still get a locked phone for that carrier. I researched this during my searches for a Note 10. Because I use another MVNO and do not wanna switch just to get a newer phone.
I did find Verizon's policy which you have stated.... and my experience from the past is that you have to make sure it is unlocked while you are still on that carrier as a legit & paid up customer.
I also from the past , get this...... On Sprint.. I was with them for years starting on the Cool Sero plan. (Not cool anymore) after contracts were up I would just buy newer phones. Well.... I left Sprint & had a bill. I just had some employment issues at the time. Then it was with a Note 4 that I DID NOT BUY FROM THEM. Having a bill.... they blacklisted that phone... lol. I still have it cause well it's the last Note with an IR blaster & there is still a community for it working to get newer software on it. You can put Pie Android on it.
So..... if you still have Verizon try factory resetting the phone then pop that SIM in. It should still work for Verizon. If you still run into that message. Another option is to flash the Verizon firmware onto. A kind of rewriting over it with Verizon again. Then try it. If you can get passed it... unlock it then with Verizon. & make sure the time frame their unlocking policy states is passed.

Also.... something I just confirmed. You will need to get a straight talk sim card for tmobile. You may have a sim card from them for Verizon I your phone now. Someone mentioned Straight Talk as Verizon which is true but they are also Sprint Tmobile ATT. BUT.... to get the most out of your phone feature wise you will need to grab a straight Talk tmobile sim card. Tmobile is more liberal than the rest. You more likely have a better time getting wifi calling and stuff to work.

Does anyone have a non blacklisted imei for SMG973U and a way to flash it onto an old device? Someone sold me a device that wasn't paid for and Verizon won't fix it

Is it locked or blacklisted? Their policy is 60 days and that's required by law so ?*

Question Completely lost here. Tmobile to Verizon

Afternoon all. Haven't been on these forums in some time. Started on the galaxy nexus and eventually faded away from any tinkering a few years ago. Currently using an S21 Ultra that was t-mobile locked. Got it unlocked and switched to Verizon. Trying to research everything I can to get myself on the unlocked or VZW software to make sure I've got all that I should be getting from VZW.
I've so far found samkey to change ny CSC, unlocked software and a whole bunch of other **** and I'm completely lost
Any chance I can get pointed in the right direction? Nothing seems to make sense to me for some reason.
Sorry to come off as a bit stupid, I'm just very much out of practice.

It probably work better on AT&T I think.

The phone has all the radios needed, just have to update the software/csc to make use of them.

You're kind of in no mans land. Unless you have a very good reason to change service to Verizon, Tmobile would be the best option. Samkey won't change your Primary CSC to VZW. Verizon Firmware will remain in conflict with your TMO Primary CSC. Hard to say what compatibility issues this evokes. Samsung is making it more challenging to mix and match Firmware/CSC's. If you have a Multi-CSC device normally you SHOULD be able open the dialer and enter *#272*IMEInumber# (In the thread replace IMEInumber with your actual IMEI Number). Press the Dial Icon, you should see a screen with the list of available CSC codes for your device. Select VZW and tap the Install option. Another user with similar issues stated Android 11 eliminated Multi-CSC options so if you are bent on having Verizon as your Service Provider give it a shot and see what happens.

Circumstances changed and my reception has taken a serious downgrade. Add in the awful experience getting the network unlock done. I changed to VZW already.

Well if you're fine being on "unlocked" firmware, just flash to G998U1

Honestly, I haven't flashed a phone since my galaxy s5. I'm in the exact opposite situation you're in. Was going to try flashing tmobile firmware, and saw this post. Curious if it all worked out for ya

Not hard at all. Fire up ODIN, use the XAA (Or whatever region you are) U1 firmware, flash the wipe CSC in ODIN, boot, insert VZW SIM when it asks. Done.
*Edit I flashed a Tmob to unlocked in about 5 minutes. Check the U1 firmware post for instructions. https://forum.xda-developers.com/t/...1-firmware-links.4220223/page-6#post-85580269
