Verizon Note 8...T-Mobile sim - help

Hello all, new here and I just purchased a Note 8 from Verizon. The device is paid off fully and i wish to use my T-Mobile simcard in it but it does not seem to be picking up a signal. I did update the verizon software to the latest version when i had my verizon sim card inserted. Verizon customer service told me i need to reset to factor setting then my t-mobile sim should work but this has not helped.
How can i get my t-mobile sim to work? Any help appreciated as i am new to android phones!
Thanks

Hi there, you must flash the new N950U1 2BQK1 or N950U 2BQK2 stock firmware to have full access of T-MOBILE Network. It's the only way it will work, I have AT&T NOTE 8 working on Verizon network with zero problem.

It's a very easy process to flash the 4 US Carriers firmware, I have done it more than 50 times and I'm not a developer.

I would like to know where to get the firmware and with what do you flash it with? Is there a instructions thread or link.
It's been over 5 years since I have tinkered with a Samsung device.

Hi there. You'll need to have your Note 8 Bootloader version on level 2, meaning 2BQK2, 2BQJA or anything with 2 before the last 4 digits.
1) tmobile SIM card in device
2) Odin v3.12.7 make sure extract
3) 2BQK2 firmware extract all files
4) put all 4 set of firmware files in the right manner, bl,ap,cp and csc. Don't used home-csc only CSC.

First instructions is for if you want stock US CARRIER BLOATWARE FIRMWARE, second instructions is if you want SAMSUNG STOCK FIRMWARE. Follow steps and everything will be fine, happy flashing.

So wait, I have a Verizon Note 8 (currently using MetroPCS perfectly), but I wanted a stock Samsung ROM (without the Verizon crap on it), I can just flash the second set of files instead and done with it?

Yes

Can I use a gsm sim card and a verizon sim card at the same time on verizon branded phone? I see you have to flash the firmware above but am wondering if this would help me.

So much misinformation in this thread.
I don't even know where to start:
The OP was asking why his T-Monile SIM wouldn't work. It doesnt matter which firmware you're on, if the Note 8 is unlocked (the Verizon Note 8 IS unlocked), and it has a clean IMEI, and your SIM is already activated, then it will get 4G LTE. I know. I have a Verizon Note 8, and use it on Tmobile. I used it for over 24 hours with my T-Mo SIM but running thr Verizon firmware with no issues. Only reason I flashed T-Mobile firmware was to rid myself of Verizon bloat and to get wifi calling.
As far as bootloader, that has no effect on the SIM card working. The OP would need a v2 bootloader firmware if his current firmwarealso had the v2 bootload. It probably does, so thats a moot point, but the implication was the v2 bootloader was the only one that would make his SIM work.
I hope the OP got it all figured out.

plus the second SIM wouldn't have an IMEI assigned to it.
And I agree the OPs best bet is to flash thr T-Mobile firmware. But his issue was he wasnt getting a signal at all with his T-Mo SIM. Flashing firmware won't fix that. Source: I have a VZW Note 8 on T-Mo. Used it with the VZW firmware and a T-Mo SIM with no issues.

Another user had SIM issues and flashed back to factory (theirs was unlocked) then changed carriers and SIM worked again...sometimes a clean flash can work...

Hi all. For me I flash all firmware at clean wipe, never any issues. I have an unlock AT&T Note 8 unlock running the latest Verizon firmware with VZW SIM active. I also have a t-mobile S8+ unlock and running the latest U1 firmware and working with Verizon SIM active. I constantly switch my firmware between tmobile, verizon and at&t to see performance and what ever else feature added.

How did you get ATT N8 to work on VZW? I flashed my Tmo to VZW and i could never get speeds above 1mpbs. Even with unlocked firmware it did not get anywhere with VZW. I heard that its because the IMEI is not in VZWs database.

Hi there. My AT&T Note 8 works great on Verizon network, it's running the latest N950U1 Firmware 2BQL2, everything works great. It will work good on T-Mobile too, lately tmobile network giving trouble, sometimes less than 1 mbps on download. Since June 2017 I been having trouble with tmobile network in my area and around, so I switch to Verizon, couldn't bother the crappie service. My location I get 215 mbps on my note 8, IPhone 8 plus 147mbps download. I prefer Tmobile but it's not working good in area anymore.

@Mr. Orange 645
I currently have a Verizon Note 8 with a TMO SIM and I'm getting 4GLTE but a few problems. Most of the incoming calls forward to voicemail and all outgoing calls the data has to drop completely before the call can connect. Will doing the carrier switching updates listed in the link above as well as flashing T-Mobile firmware assist with this problem? The phone is on 2BQK2 currently.

Verizion note8 with tmobile sim card
This is what happened when I changed carriers from the original verizon note8, on verizon network, with verizon sim and the most recent verizon pie update, to a carriers sim, that is tmobile service. And what happens, I didn't even think was possible... I put the new carriers sim in, truconnect, booted and let the phone register the new sim and network. Checked for update.... the was one, let the phone download and update. And you know how Verizon's boot logo is... it wasn't anymore. Booted the tmobile boot logo and sounds, strange. I'm not super noob and the little bit of knowledge and experience that I do have with roms and updates across carriers usually require physically flashing the rom. Correct me if I'm mistaking. Continuing.... optimizing apps....., huh?! The update flashed the tmobile software, without effecting any personally installed apps. Though the update did remove all the verzion software/bloatware, without permissions, and installed tmobile apps. 2 that are meant for user usage. They are tmobiles device unlock and the tmobile app. Which I might add, do not function, I surmise, because in not on the actual main tmobile network, but a scabbed on. I have never seen or experienced anything of the short. Please tell me if this is normal.? I was a bit upset. I did not give any carrier the permission to delete or install any app on my phone. But maybe things have changed since I dabbled. And If they have, maybe this might help the people that have been using Odin to get tmobile version rom while originally being a verzion phone. I dont think it's normal. Please tell me if this has happened to you.

Any way to get wifi calling on unlocked s9?

Is there any way to get wifi calling on att with an unlocked s9 from best buy? Flashing att firmware or would it be best to get the att model? Must have wifi calling for work reasons and I hate all the bloatware but might not have a choice.

at&t probably blocks it, if you don't get their version. I have an unlocked, but on T-Mobile, and it works.

I flashed the AT&T firmware on my unlocked S9 and wifi calling and video calling worked.
With the stock firmware on the unlocked S9 nether option was there

Can you point me in the direction of a download for the stock firmware for AT&T? I'm wanting to do the same as well, but feeling pretty clueless about where to obtain it. thanks!

Same here. It works for me on T-Mobile

If I flash the att firmware will I still get firmware updates?

if you flash the att firmware or buy it straight from att you will end up a device supporting the same capabilities. So it's down to your tech skills or budget.

Where can I find the latest att firmware? I did not see it on sammobile.

How to
Step 1 Go to this thread for Firmware (thanks @iBowToAndroid)
You will want to go to the link for the U firmware and find the folder with the AT&T userdata file (RB7) download the user data file and the full firmware.
Step 2 Go to this thread to get the modified version of Odin that recognizes the GS9 firmware files. (Thanks @mweinbach and Raymondf )
You will then flash the downloaded files from Step 1 in Odin, after flashing the firmware the phone will boot into recovery and you will need to wipe data and cache.

Thanks so much... that did actually help me... as a fairly tech savvy person who doesn't really get into this stuff much, the lingo I didn't know was leading me astray... I had come across that thread but didn't recognize it as anything that would help me. Thanks again! Onward to bricking my phone!

Thanks for the info. A follow-up question: is it possible to flash it back to the stock unlocked firmware? The reason is that I'll need to use foreign SIM card when I travel overseas.

I have unlocked version on TMobile and wifi calling works just fine.

Do you have to flash the att firmware to the unlocked version in order to get VoLTE? I don’t care about WiFi calling, just hd calling and being able to stay on lte when making a call, rather than have it drop to HSPA during the call.

I understand, but unless att has changed its policies in the last month, if u do not have an imei number on that account that is an att phone with wifi calling it will turn itself off as soon as your phone is interrogated by the network. Theres 100 threads on it , applies to unlocked s8, s7, etc...
Toggle is there because of firmware, not because it works.

Any help/guidance for me??
I have tried a few times to use the March 2018 RB7 files with the ATT user data to get my phone to ATT stock - primarily for the Enhanced LTE (data and voice at the same time), as well as Wifi Calling. I can't get that version to load. I did get a more recent version to load (RK1) - and maybe that is the issue. Just wondering if there is a newer set of files and what specifically I should use (AP,BL... UserData) to get the phone fully set to AT&T. I now have the wifi calling option, just can't get it enabled. Any help is appreciated.

When you try to enable it do any of the AT&T Wifi calling configuration screens pop up?

Can all USA Galaxy S9 models be flashed to each other's firmware?

I've read that the Galaxy S9 hardware is identical for all carriers in the USA.
If I bought a factory unlocked Galaxy S9 can I flash it to the carrier I am using (Verizon, Sprint, T-Mobile, AT&T) to enable carrier specific software and features? Can I flash it back to the unlocked firmware?
I already see a thread about flashing the unlocked firmware to carrier models so I am assuming there are no issues there.
Can one carrier model be flashed to another carrier model?

No, bootloaders are different, with the S7 there was an unbranded U firmware that was compatible with most of them, unlocked firmware will be that one for the S9, but no you cannot just flash different device firmwares to the wrong model

I was able to flash the ATT rom onto my Verizon S9. I got a VZ s9 from work but I'm on ATT. For the most part it's worked great, I had done the same thing previously with a Galaxy S7. I say for the most part b/c I am on here tonight to post a question myself about the fact that I'm getting a delay with MMS messages. I imagine it has something to do with the APNs I have setup, but I can't seem to figure it out.

Did you have to flash to the U1 software first?

I do think that is what I ended up doing... tried to go directly first and it kept failing. Got fed up and decided to just try and put the bone stock rom on it, and that went on really easily.... so after using it like that a few days I tried to drop the ATT rom on it and it worked without issue.

Yes, but you need to go to the u1 firmware 1st then to the other carrier firmware. Also make sure you avoid the newer firmwares with the new bootloader, as the unlocked model and certain carrier models don't have the new bootloader.

I tried downloading vzw firmware G960USQS3ARI6 to my unlocked sprint s9 and still not vzw flashed. want to do this so can have voice over LTE. Any other steps im missing? flash went through but still sprint

As soon as Firmware ver. 3 came out for the G960U1, I was able to flash it to my Sprint G960U and finally have VoLTE, WiFi calling and stable LTE for MetroPCS. Used samkey to unlock it from Sprint. My phone is actually performing much faster without all of Sprint's bloatware hogging my RAM and storage space. I can confirm that OTA updates still work the same...I received September's security patch (current) with no problems. Device is still official status and Knox hasn't been tripped.
A lot of people think you can just flash the carrier firmware of your choice and boom, it works...I had the same thought process....that's not the case. You have to make sure that there is a matching firmware version for the carrier you want to flash to, as well as make sure the G960U1 firmware version (the unlocked version of the S9's software you have to flash first before even carrier flashing) is the same version of what is installed on your phone now. It's easy ya'll......just READ lol.
I'm in love with my phone again thanks to XDA. ?

Well first off, you have the unlocked phone. I don't. My G960U is originally from Sprint, so I'm not sure about carrier flashing regarding the G960U1. I thought it was supposed to provision itself after you put the sim in, and the associated carrier apps will download since it's the unlocked model...but I may be wrong...

I know so many people have already answered your question from some saying No to others saying Yes but you need to Install U1 first and Bla Bla Bla.
I want to give you one specific answer: With S9 you can any Carriers firmware you wish or even Unlocked phone's firmware. You will never have any issue. And you don't ever need to flash U1 or something else before changing carrier firmware you can Flash from ATT S9 firmware to VZW S9 firmware without any issue. You can also flash from U to U1 which is from Carrier specific to Unbranded/Unlocked but only hiccup is original Odin will give you SHA-256 error, which is normal because you are flashing U1 firm to U device or vice versa. This error can easily be resolved by used Patched odin that disabled SHA-256 check. And trust me you will never have any issue.
You will never want to do this but I have gone as far as mix-matching U and U1 firmware together as well. Like flashing AP, BL and CP of U device but flashing CSC of U1 device. and it still works.

hey there, a little late to the party, having trouble with going from a Verizon to a Sprint, even by way of U1. I can't get any of them to work. And I've been told I have to go from VZW to U1 before I went to Sprint. Is that not the case? I'm having a hell of a time getting anything to flash, everything fails.

well, I tried to load the Sprint image from the VZW, no dice. It said it passed, but upon reboot loaded up the old Big Red (even with the Sprint SIM in it).

Help with getting volte working on non ATT S9

Hey can anyone give me advice on how to get volte to work on my unlocked s9? I've flashed everything from the ATT rg7 folder including the att userdata file and still no volte. The software tells me I should have it but nothing will enable or work. I even tried putting another s9 (actual att model) imei number on that phone numbers account and still no go. What am I missing??? I must be missing something.... I'm at a loss.

So do you have all the AT&T Apps? Also the only way to get the imei of the the AT&T phone to stick in AT&Ts system is to have them set it while you are using the AT&T phone.

explaining the carrier switch capabilities (ATT->Tmobile)

I have a "carrier-locked" ATT note 10 (SM-N975UZKEATT) that I would like to use on Tmobile.
1) Is the only thing required to get the phone working with Tmobile a carrier flash? Do you really no longer need to unlock the device (carrier unlock)?
2) any guides that show this process from att to tmobile?
Thanks

You still need to get your device carrier unlocked before it will work on another carrier.

Adding a little more to this:
1.) As an option (if preferred) you can most likely just keep the firmware installed on the phone and use it as it is. Tmobile is rather friendly with BYOD compared to AT&T. The phone will reconfigure some settings based on the settings that the Tmobile SIM card will have on it. Once unlocked just put the Tmobile sim card in and that should be all it takes. You may need to double check the APN settings though to make sure they are complete and accurate.
