You can flash the userdata from any other firmware to the U1 to get the carrier bloat. I am not sure about mixing and matching CSC's though but in theory, it should work. The U1 will download and install everything for US carriers but not for the Canadian carriers. The W is essentialluly the Canadian U1 that downloads what it needs for the carrier based on the SIM inserted during the setup.

Yep on all counts. Dobuble checked settings again and its enabled. ODIN settings check out, just those 2 checked each time I attempt. I've used the 2 versions of ODIN in the OP (PrinceComsy and the patched ODIN) as well as the slightly newer one you linked me; none worked - ran all as administrator. I'm really puzzled. I've also tried with 3 separate USB cables in a front port, rear port and hub as well as 3 different firmware.

I'm convinced it has to be user error at this point. Is there a bare minimum I can flash without messing with the phones functionality if all parts are unable to flash? All parts seem kind of necessary to not screw up the phone. I've been flashing BL CP CSC and AP all at the same time and not flashing Home_CSC at all or anything in the UserData field.

I have to reinstall one of my PC's later in the week. When I get everything reinstalled, I will see if anything jogs my memory as to what might be the issue or that we are over looking.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Symber:
Holy crap its flashing! Finally! lol Now to wait and see how it goes. This is a combo I've tried at least half a dozen times. Rear port, stock cable, patched ODIN, N950U1UES4CRE1_N950U1OYM4CRE1_XAA firmware. I have absolutely no idea why it worked this time other than this phone is apparently slightly less stubborn than we are.

Edit: Passed! Thank you for all the help and great ideas. No idea if it was totally necessary, but I give all the credit to the rear port idea you suggested and switching through various cables that [MENTION=4629807]UltraNoob[/MENTION] suggested. You guys rock, thanks for the patience. Now I just hope the phone works lol

Use the samfirm tool.

Model SM-N950U

Region TMB

It will download the most current Odin firmware package.

I installed the W FW and i still don't have access to VoLTE or Wi-Fi calling. Any ideas?

***edit**

Ignore this, i made a mistake and reflashed the U1 FW instead of the W. I flashed W correctly now, and all features are available
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Good to hear! Enjoy!
[Samsung Galaxy Note 8 Guides, News, & Discussion] UltraNoob:
Hopefully my last question here haha.

I was using the W fw, and although the options are available for VoLTE and WiFi Calling, they do not work. This must be a restriction on the carrier side.

I would like to go back to the U1 firmware, but i did apply an update which updated my BL to V3. Can i flash any U1 FW that is V3 and up to go back?
[Samsung Galaxy Note 8 Guides, News, & Discussion] The_Keeper86:
I was a dumbass and decided it was a good idea to go back to stock and it installed the SQS4 update. I'm guessing I can't install the factory unlocked firmware? Wish I could downgrade back to U3 I kinda miss root too.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Canadian carriers require you to call in to activate WiFi Calling. Telus currently doesn't permit WiFi Calling on anything outside of the LG G6 and LG V30. There are lots of unhappy Samsung owners complaining about the lack of working WiFi Calling in the Telus Neighbourhood forum. Did you try double checking the APN settings? Rogers uses the IMEI to restrict WiFi Calling and VoLTE devices to only devices sold by Rogers directly.

You can flash any W or U devuce to U1 as long as you have a firmware with the same bootloader vrlersion. If you are on the v3 or v4 bootloader, you shouod be able to find a U1 ODIN image to flash with either of those bootloaders.

Hello,

I have the T-Mobile version of Note 8 (SM-N950U) and had successfully flashed it to the Verizon firmware using the instructions in this thread a few months ago.

Baseband version: N950USQU1AQI5

Android version: 7.1.1 (Nougat)

Service provider: VZW/VZW/TMB

How do I get it to the latest Verizon Oreo firmware? I don't mind performing a factory reset and doing it from scratch. I cannot update it via OTA since I am with a Verizon MVNO in the US.

Thanks for any assistance.

Thanks Kevin. So do I just need to perform a factory reset and flash the above Oreao 8.0 Odin files and that's it?
[Samsung Galaxy Note 8 Guides, News, & Discussion] kevindevonwilliams:
A reset is not needed so early, you can flash the device as it is using the CSC, not Home CSC and that would give you a clean install.

I had oreo unlockedfirmware running on my phone. Overnight the phone updated on its own. Can I flash an old Nougat firmware or am i stuck with this most recent firmware? Thanks
[Samsung Galaxy Note 8 Guides, News, & Discussion] fogame:
If your on the 4th bootloader version, your stuck.

Post your bootloader and we can help check.
[Samsung Galaxy Note 8 Guides, News, & Discussion] gregcapps:
No going back to Nougat since you are on bootloader v4 and Nougat is v3. Can't downgrade the bootloader.

Am I able to use a custom Oreo rom? Or am I stuck with this current rom?
[Samsung Galaxy Note 8 Guides, News, & Discussion] gregcapps:
Don't know. Haven't even attempted to root because of the charging issue it causes. I don't think there is currently a root method for Oreo
[Samsung Galaxy Note 8 Guides, News, & Discussion] fogame:
No root method for Oreo so as it stands you are stuck.
[Samsung Galaxy Note 8 Guides, News, & Discussion] maxshop:
So I was able to install Oreo 8.0 successfully. I used Odin3_v3.13.1 to flash. Here is my feedback and questions:

1). What is Odin3_v3.13.1_3B_PatcheD used for and was I supposed to use it instead?

2). The Service provider is now: VZW/XAA/TMB. Shouldn't this be: VZW/VZW/TMB?

3). The Samsung Calendar "List" widget does not refresh. I searched online and tried many things, but none of them worked. It seems like an issue with Oreo (?)

Thanks
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
XAA is what you get when either your SIM isn't installed when flashing to U1 or when you don't fully wipe when changing firmware. In some cases, leftovers can cause issues, like installing the correct settings for your carrier, features like WiFi Calling, etc.
[Samsung Galaxy Note 8 Guides, News, & Discussion] kevindevonwilliams:
Modded Odin is mainly used for flashing from U to U1 or vice versa. As in flashing from carrier firmware to unlocked firmware or from unlocked to carrier branded...

What sim are you using in the device currently? Did the device wipe when you flash to Oreo?

The calendar issue am not sure cause I don't really use it..
[Samsung Galaxy Note 8 Guides, News, & Discussion] maxshop:
I am using a Verizon MVNO (Red Pocket) SIM. I did not wipe the device prior to flashing Oreo. I thought the flashing would do it - no?
[Samsung Galaxy Note 8 Guides, News, & Discussion] kevindevonwilliams:
Maybe that's why it says XAA, try using a different SIM from an actual carrier and see if it changes.

Normally if you flash using the CSC it would wipe but not always guaranteed.

You can however wipe and set up from scratch to make sure all old files are gone etc
[Samsung Galaxy Note 8 Guides, News, & Discussion] jahmezis45:
Is there no video calling on Oreo?
[Samsung Galaxy Note 8 Guides, News, & Discussion] maxshop:
Ok, so here is what I just did:

1). Took the SIM out

2). Performed a factory reset

3). Flashed the Oreo firmware (again) and performed a factory reset

4). Powered on the phone and it showed: VZW/VZW/TMB. So far so good.

5). Powered off the phone, inserted the SIM card and powered it back on

6). The phone now shows: VZW/XAA/TMB

Not sure why...It did not do this on Nougat 7.1.1 after I had performed carrier switching from TMB to VZW and then flashed the VZW 7.1.1 firmware
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Further proof that the extra wipe before flashing saves a lot of possible issues and hassles later on.
[Samsung Galaxy Note 8 Guides, News, & Discussion] maxshop:
Agreed - although the end result is still the same as before i.e. VZW/XAA/TMB instead of VZW/VZW/TMB
[Samsung Galaxy Note 8 Guides, News, & Discussion] kevindevonwilliams:
All your Verizon features working?

I think the reason you are seeing XAA is because Samsung is recognizing the SIM as international since it's a MVNO and not an actual carrier it self like Verizon, ATT, T-Mobile. But the vzw infront means you are running the Verizon firmware and the TMB means it's a T-Mobile brand device. The second code is base on the SIM
[Samsung Galaxy Note 8 Guides, News, & Discussion] maxshop:
Well, the Verizon features (VoLTE, Wi-Fi calling, etc.) are not available since I am with a MVNO. So they didn't work Nougat and neither do they work in Oreo - which is fine with me. What is throwing me off is that I had VZW/VZW/TMB in Nougat, but now have VZW/XAA/TMB in Oreo. I am with the same MVNO and have not changed the SIM, etc. So I am not sure why Samsung now suddenly thinks that the SIM is international.

Also, when I look at the SIM Card Status under "About Phone", it shows the Network as Verizon. I am able to make and receive calls, send text messages, etc. - so everything appears to be working.

The only other difference that I see is under Mobile Networks. I noticed that there are no APN settings to add/view/modify, and the Preferred Network Mode is set to: CDMA/EVDO/GSM/WCDMA. However, when I click on it, I don't see it as part of the choices that are presented which are: LTE/3G/2G, 3G/2G, 3G only and 2G only. I don't remember seeing these in Nougat.

Guys, Iam on Verizon N950USQS2BQK2 Nougat. But my SIM is from ATT. I am unable to use ATT calling at this tim, because I am on verizon phone version N950USQS2BQK2. What's the best version to flash to ATT firmware. Can you assist me on this to switch to ATT firmware? If I am moving from Verizon to ATT, will it lock the phone ?
[Samsung Galaxy Note 8 Guides, News, & Discussion] thedrizzle:
Firmware is universal. If your phone is originally a Verizon phone, it is unlocked and should just work with at&t, although you probably won't have all the features unless you factory reset it. Switching carriers will not SIM lock the phone.

But, if you'd like to do the full carrier switch, you can because you're still on bootloader 2; follow the directions in the OP to do the carrier switch, then flash the full at&t firmware if you want that experience.

Looking for some advice not a noob at all but I must be missing something I flashed the unlocked verizon firmware onto my Verizon note 8 and the service kinda sucks where I live and rely on wifi calling so I tried to flash the verizon firmware over it and it keeps failing with a mis match or something of the sorts. I originally flashed the newest verizon unlocked firmware and took an update and tried to flash the only Verizon oreo firmware I could find.

If I could get wifi calling and what not on this software that would be great but I'm not having much luck with that either without having to root the phone. I'd like to preserve my secure folder. Any help or advice will be greatly appreciated!
[Samsung Galaxy Note 8 Guides, News, & Discussion] jahmezis45:
if you flashed the newest version you can't flash anything else from my understanding. That happened to me. I kinda wish I read that on the download link it would have swayed me not to flash

Have a Tmobile Note 8 that I was able to unlock and needed to switch over to Verizon firmware. This worked beautifully! Thanks for the post!
[Samsung Galaxy Note 8 Guides, News, & Discussion] whatsitsnamenow:
I have a T-Mobile Note 8 that I bought from Samsung. I got the phone sim unlocked and was using it for a few months. I flashed the unlocked xxa firmware after the phone was sim unlocked.

Then the phone had a defect so I flash the phone back to T-Mobile firmware and send it back to Samsung for repairs. They replaced the main board and sent the phone back to me. But the phone is now sim locked to T-Mobile again even though the imei is the same as before. They say it is not suppose to happen but if it is lock to T-Mobile again just submit another request to unlock from T-Mobile. Already did that but the problem is that the "device unlock" app doesn't work correctly. When I click on it, it just says device not recognized by provider. It is suppose to give the option of temporary unlock or permanent unlock but I can't get it to go to that option.

So far I have tried, clearing "device unlock" cache and data, clear phone cache and data, factory reset phone, reflash the firmware (v4). Tmobile says that they have done all they can on their end. The device unlock app needs to work and communicate with their end or it won't work. They told me to contact Samsung to get that fix. Samsung told me that device unlock is not their problem call T-Mobile.

Does this seem to be firmware problem or something else? Any help would be appreciated.

[Samsung Galaxy Note 8 Guides, News, & Discussion] markfothebeast:
Perhaps you need to edit the APN settings. Android 8.0 on my Verizon Note 8 had hidden the APN settings menu on me so I had to use the "Change APN" app (I believe it's called) to pull up the APN settings menu. Locate the appropriate APN settings via Google search for the carrier you are attempting to connect with.

I am having similar issues with a Verizon Note 8 and Android 8.0. The device is paid for and I cancelled Verizon and went to Straight Talk using the Straight Talk BYOP (bring your own phone) CDMA Verizon SIM. I was unable to send or recieve texts, calls, or mobile data. I had to use reset "Network Settings".

After that I was able to make calls but could not send text/MMS. I installed a 3rd party texting app which fixed that issue. However, I still do not recieve mobile data. I went through and removed the Verizon bloatware via ADB and was analyzing some of the APK files I'd extracted from some of the network related services. Several background services and applications on the phone appear to be intended for use only with Verizon. Including some Samsung specific OEM features. Which I believe may be at fault.

Verizon confirmed my device is unlocked and was NEVER locked to begin with. So anyway, I'm going to give the US Unlocked XAA firmware a shot. I've had to go through and read the tutorial several times to understand it. My ADD brain is struggling to absorb some of the information. I'm hoping that this XAA firmware is okay to install on the VZW N950U.

One thing I should mention, the latest Verizon update had blocked some key-pressed boot features so some VZW Note 8 owners will need to use ADB to access boot functions.
