... OK, I'm sorry for the clickbait title, but I think it could work.
I have a US Cellular Note 4 in-hand, and with CF AutoRoot and Flashify, it's permanently-rooted and TWRP is flashed as a custom recovery.
The device is carrier unlocked "for use on any CDMA network" and by default... it supports all the same bands as Verizon, with the exception of LTE band 13, which isn't an issue for me. (There is a method of enabling it, but that's a topic for another thread)
So, essentially, it's a Note 4 running on Verizon bands, and the bootloader is unlocked. Other than the USC software running on the phone, it's pretty much a Verizon Dev Edition in USC clothing.
Now... Verizon is currently working on acquiring the MEID from US Cellular, so I still have yet to actually get the phone activated... but everyone is optimistic. Even Verizon, and they're never cool with anything like this.
So my question: This USC Note 4 does not currently recognize a Verizon SIM. It came with a USC SIM which it recognizes fine, but I get "Invalid SIM" in my ongoing notifications, and "unknown" under About Phone > Status > ICCID. Verizon has told me that when the MEID transfer is complete, the phone will magically recognize a Verizon SIM. Is there truth to that? My thought is that I might need to flash Verizon software on the phone to get the SIM to recognize. Sooo...
Is it safe to flash software from a Verizon release to this phone? Will flashing a Retail Edition rom in Odin lock the bootloader like it does on the Dev Edition?
Am I even accurate in thinking that there's some kind of support file that's missing from the USC rom that allows the phone to see my Verizon SIM?
If anyone has any knowledge of these topics... please reply.
Thanks!
So I just switched to T-Mobile from Verizon and kept my Galaxy S8+. Obviously, I cannot do the system updates through the phone anymore. Therefore, I wanted to know if there is a way to flash the T-Mobile firmware so I can operate the phone as if T-Mobile issued it.
If that is not possible, any suggestions?
Thanks!!!!
I'm sure this is a good place to start. Please research and read through good before proceeding. I almost screwed up my phone going from Verizon to unlocked.

I switched to AT&T on my Version S8 plus. I just updated to the latest Version update by taking out the sim card, turning on Airplane mode and connecting to wifi. This allowed me to take the update.
I'm sure you can flash to another carrier's firmware. Take a look here:

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.

Unlock firmware
1) any carrier SIM card
2) Odin v3.12.5 Prince Comsey or modified Odin, make sure extract
3) 2BQK1 firmware, extract all files.

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.

Nevermind, I fixed it. I had to perform the carrier switch and flash Tmo's firmware. Running perfectly!

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.
Hey guys, just had a question. I have a SM-N920A phone. Will it brick my phone if i flash it through ODIN with "N920TUVS5ERC1" thats meant for the SM-N920T Tmobile Note 5. I hate the AT&T bloatware and would like to have the Tmobile Version of the Note 5. Just not sure if the Tmobile Firmware will brick my AT&T phone. Will it work ?
Thanks guys

It will not work. Locked bootloader for AT&T signed software. Maybe it will flash but virtually no chance it will boot. Even if it did boot, there most likely won't be any cell service.
Oh ok, i see. Yeah you problaly need the same basebands or something for the firmware to work. Well, thanks i appreciate it
If you did get it to boot, using an unlocked modem firmware would be the trick to getting cell service again.
Please, please, don't flame me if I bumped this as it's been inactive for a while... but I wanted to know if there was any progress with this?
I also have a Note 5 N920A that I'd basically like to make into a N920T. I understand that the bootloader is unlocked, but where keys exist, is there not a way to unlock it? I've been out of the development community for quite a while and will catch up a little but I hope someone would have time enough to explain a little.
I unlocked this phone and use it on T-mobile but it doesn't get service where the almost identical T-mobile version of the phone does...
What if I left the bootloader alone and just wanted to take full advantage of T-Mobile's LTE bands? Can I just flash an unlocked modem from _____?
What're the workaround options for this?
Please and thanks in advance
I've been searching for the answer to the same, if not similar, question. I'm trying to find a way or work-around to get T-mobile wifi calling to work.
I flashed att firmware on an unlocked note 10 plus but att still sees it as an unlocked phone. Is it possible to change the phone to completey read as an attvbranded model? I called to see if they could provision the IMEI of my phone and they were able to tell right away it was not one of theirs, even though it was running att firmware.

No, because (as you found out) the IMEI number is not from an AT&T branded phone.

I have a GOOGLE unlocked phone. I flashed N975U firmware on my phone and also flashed ATT USER DATA at the same time.. When my phone booted up - it had all of the ATT BLOAT that comes on an Att phone - it booted up with the ATT LOGO - it shows ATT ICONS in the Status Bar for Data (5GE instead of showing LTE or 4G) and I have Wifi Calling and Video Calling working on my phone...
https://androidfilehost.com/?w=files&flid=301224
That is all it took. I didn't have to call ATT - It all just worked - and it was not working that way BEFORE I flased Userdata.
YMMV but I have heard about others who had the same experience. Go tot he N975U Firmware thread and find the download for ATT USERDATA - That is where I found it....
Hope that helps you.....
Pixel and iPhones are supposedly able to do those things. I think that may be why it worked for you

Wish it was possible, but unfortunately no way exists.
If you have WiFi Callling, Video Calling and Volte working, why does it matter if ATT recognizes your phone as one of theirs or not? Just curious about what you are trying to accomplish ?
