This seems very similar to what I did with my S9, so no longer follow the steps in post 2 for a carrier switch? Looking to go from AT&T to Verizon, I would flash the U1 XAA firmware and then the U Verizon? Keep Verizon SIM in during both flashes? Dont use Home_CSC and dont change any default settings in Odin. I see you mention to wipe after each flash, is that just from the regular android menus after you boot up?

If I stopped with just doing the U1 XAA I would lose some of Verizons advanced calling features?

Thanks.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Using the correct CSC should wipe the device. In order to get Verizon advanced features working, you need to continue on to flash to the Verizon U firmware. The second post should still be relevant. Most say you can skip the U1 step when cross-flashing, but personally, I find that not skipping it always guarantees a smooth transformation from one carrier firmware to another. The reason for keeping the SIM in during flashing, is to tell the device that it isn't going to be receive the firmware of the place of purchase. If you leave the SIM out during flashing, it assumes you are flashing the same firmware that corresponds with where the device was purchased. This can cause the conversion to not complete because the device is assuming you are going to keep using what it came with.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jschramm:
But for my situation do I need to follow anything in Post #2? Or am I just following Post #4 "Flashing Unlocked Firmware" and then Post #3 "Flashing Carrier Firmware"? Thanks.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Skip the stuff in Post 2. There is no real need to mix firmware anymore.

Just wanted to add a quick little note for those interested in upgrading to Pie. I have a Verizon Note8. I used OP's instructions to switch my ROM from Verizon Nougat stock ROM to the unlocked carrier Oreo ROM. Worked great! Used the ROM w/o any issues whatsoever for a few months. Last night I decided it was time to upgrade to Pie. I installed Smart Switch on my PC. It successfully upgraded my unlocked carrier stock ROM to the latest version of the unlocked carrier Oreo ROM...SB1 if i remember correctly. Phone rebooted automatically... I disconnected the USB cable and reconnected... The Smart Switch app told me there's another update... Pie! I went and ahead and proceeded. Phone rebooted again and I now have unlocked carrier Pie. I didn't lose data... My old apps, photos, text messages are still in the phone. It did give me a warning though that some old 3rd party apps may not be updated to Pie, so just a heads up in case you run into 3rd party app issues after upgrading.

Are you using the modded or patched ODIN 3.13.3? Do you have USB Debugging enabled in Developer Options?
[Samsung Galaxy Note 8 Guides, News, & Discussion] dartoo:
ok turned on usb debugging it worked.

i left out this file

flashed all other. its flashing now waiting for it to complete.

the VZW user data file was to be left out. right?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
You can leave it out. The userdata contains mostly Verizon bloatware. If you want complete stock though, flashing it ensures it is jist like you bought your device from Verizon. If your device was already a Verizon device, it shouldn't make any difference at all.
[Samsung Galaxy Note 8 Guides, News, & Discussion] dartoo:
i had an idea that VZW user data would have bloatware so i left it out. was a bit confused thanks for clearing it up

just completed flashing. did a wipe cache.

[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
The USC is for US Cellular (carrier specific). The XAA U1 is a generic US focused firmware that isn't specific to any carrier. It has no carrier bloat but does have Samsung bloat. It will work best internationally.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jery grande:
same problem with my note, have you fix that??
[Samsung Galaxy Note 8 Guides, News, & Discussion] AlpineMan:
It's been a while since I did the steps successfully on my own Verizon Note8 and my memory isn't as good as before. I'm trying to help a friend flash his Verizon Note8 to Unlocked carrier Oreo firmware. Originally, he had Nougat. I think I misunderstood the proper steps in doing it. This is what I did:

0) I went to Post #4 to Flash Unlocked Firmware

1) Put the phone in Download mode.

2) I extracted the following firmware: N950U1UEU3CRC1_N950U1OYM3CRC1_XAA-Pure_Unbranded

3) Launched Modded Odin v3.13.1

4) Put AP file in AP, BL file in BL, CP file in CP, and CSC_OYM in CSC

5) Flash succeeded, phone rebooted

6) Unlocked Oreo CRC1 rom running fine.

Then after I got the ROM running, I just realized I should have gone to Post #2 first (to switch CSC code from VZW to XAA) and follow those instructions...and then go to Post #4 to flash the ROM.

Is that what I did wrong? Can I still perform steps in Post #2 and then do the steps in Post #4 again? I'm already on Oreo though. The files being referenced in Post #2 appear to be Nougat.

Thanks for any replies.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
What ypu did was correct. You can't change the CSC code for the carrier of purchase. So, you should have XAA/XAA/VZW.
[Samsung Galaxy Note 8 Guides, News, & Discussion] AlpineMan:
Whew! Thanks for confirming. I thought I was losing my touch! So is Post #2 obsolete and unnecessary when switching carrier?

UPDATE

I've re-read the the latest posts here and learned that Post #2 isn't necessary, atleast for my case. The step I missed is leaving my SIM card installed before booting my new ROM. So, I just reflashed the ROM while my SIM card is installed, and when it initially booted up, it detected that I have a Cricket / AT&T SIM and it proceeded with the appropriate settings for my SIM. After it booted up to Oreo, I reconnected the phone to my laptop and launched Smart Switch on my PC and proceeded to update twice...latest version of Oreo, and then to Pie. Thanks so much to OP and ofcourse [MENTION=3116388]jcsww[/MENTION].

WOW!!.. 1000X Thank You for this tutorial. :D

I was holding my old bricked Verizon NOTE 8 since last summer since I change carriers to T-mobile and got the NOTE 9 instead. Yeah, I kept the NOTE 8 just in case.

Long story short. I use a GOOGLE Pixel 2 with T-Mobile service as a work phone, but sometimes the battery dies too quick by the afternoon. And today i thought about it to play with the NOTE 8 in terms of software and i found this thread. Works like a charm and the T-Mobile ROM is working perfect (even WIFI calling works 100%). :D
[Samsung Galaxy Note 8 Guides, News, & Discussion] sharpeyedman:
I am really lost and need a help with downgrading and switching from Pie.

My previous Samsung phone was Galaxy Note 4 so it has been a long time.

Now I am just lost and need your help. I hope if anyone can give me some advice.

So I just got myself a Verizon Note 8 and I am using it on T-mobile. The phone came with Android Pie One UI.

I wanted to downgrade to Oreo and possibly use T-mobile version of oreo firmware on it.

I was not quite sure which procedures I should take. I tried flashing my phone with both Verizon version of oreo and t-mobile version of oreo on my phone with patched odin. All files were downloaded from the op.

Odin just gave me errors and failed. I did not want to brick my phone so I just stopped at this point. Could anyone tell me which steps should I take?

Thanks so much in advance!

If I have a Sprint Galaxy Note 8 n950u, can I use post 4 to unlock it and use it on Verizon? Also, I only see downloads for Oreo and Nougat; What if i'm on Android version 9?
[Samsung Galaxy Note 8 Guides, News, & Discussion] ooofest:
We just purchased a Note 8 SM-N950U from Swappa advertised for use on T-Mobile that shows carrier = CCT (Xfinity?) and which the seller said is Unlocked.

After putting in my T-Mobile SIM, it took about 45 minutes for phone calls, messages and mobile data/Internet to appear functional over T-Mobile. So, that seems positive.

The "Service provider SW ver." now looks like: TMB/TMB/CCT

Questions

:

1. Do I need to change the firmware for enabling Voice over LTE or WiFi calling with T-Mobile?

2. Any reason why Software Updates only seems to work when the phone's WiFi is disabled (forcing it to go over the T-Mobile network)?
[Samsung Galaxy Note 8 Guides, News, & Discussion] JLine05:
Does anyone have the latest firmware for the N950U1 they can upload for me? Sammobile isn't letting me download it. It should be the DSC1 firmware.

Since the OP let this thread die, we kind of need a new one that will stay maintained! Hopefully I'm not just missing it.

Edit: Nevermind, found at samdb.org

AT&T Firmware

Which firmware file did you use? Was it N950USQS3BRA8_N950UOYN3BRA8_ATT? When I used it with my N950U1 I don't get any of the AT&T apps/features..
[Samsung Galaxy Note 8 Guides, News, & Discussion] jschramm:
Finally got around to making the switch from AT&T to Verizon. Flashed XAA and then VZW. Everything appears to be correct, Verizon splash screen to start, advanced calling, wifi calling. Software says vzw/vzw/att, is that correct? or should they all be vzw?

[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Modded or patched ODIN and flash the full firmware. With AT&T though, they will not activate WiFi Calling and other features in any device not purchased from AT&T, even if it has the AT&T firmware.

Hi Guys, I need help with my AT&T Note 8. I mistakenly flashed T-Mobile Pie One UI firmware from Oreo on the phone. Prior to flashing the firmware, everything worked fine. After I stalling the pie firmware, I can no longer send SMS. Then I grabbed an AT&T unlocked U1 firmware hoping to get my SMS working again but I am still unable to send SMS. I really love the unlocked firmware free of bloatware but I need to get back to being able to send SMS. Kindly point me to what I need to do.

I'm trying to flash the Sprint carrier firmware for the unlocked variant (950U1) so that I can get VoLTE. There are carrier versions for both 950U1 and 950U. Which of these do I need to flash?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
There are no actual U1 carrier versions. Avoid anything that claims to be.
[Samsung Galaxy Note 8 Guides, News, & Discussion] ctasich:
Oh, I see. Both sammobile and updato have SM-N95U1 (SPR) versions. What are these?

Also, do I need to start by flashing the firmware for SPR on the frontpage. Or can I just download the latest SM-N950U (SPR) firmware and flash directly to that?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Use the latest for flashing. The U1 user created carrier versions are the userdata and CSC of the Sprint firmware mixed with the U1 base. You would not get OTA's to install normally on that mixed firmware but will get OTA's and install fine with the Sprint U firmware.
[Samsung Galaxy Note 8 Guides, News, & Discussion] dhoang:
My buddy has an ATT Note 8 currently on N950USQU1AQIA. The phone is already unlocked and he is currently using it on T-mobile. I wanted to help him out by switching the phone to T-mobile firmware. I have read the instruction multiple times but I still needed some clarifications before I start since it has been awhile since I used odin. This is my understanding from reading the instruction and if I am wrong could someone please correct me.

1. Flash COMBINATION file that matches the phone's firmware, which is AQIA, using Odin

2. Flash XAC_HOME_CSC using Prince Comsy's Odin

3. Change CSC to desirable carrier, in this case TMB, in CMD.

If successful then proceed to flash T-mobile firmware. This is where I have a question on. Can I flash to the latest T-mobile (Oreo) firmware from AQIA, or do I need to do it in an increment.

Thank you in advance.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
I'm not sure what you mean by a combination file but that sounds nothing like the method I have used repeatedly successfully.

Download the XAA U1 firmware, extract it, make sure USB Debugging in Developer Options is enabled, reboot the debice in Downloade Mode, delete the HOME_CSC, connect your device tonthe PC, verify the driver is installed for it, load up the modded or patched ODIN 3.13.3, flash all of the remaining files (which will wipe the device) because that is necessary for a proper conversion.

You could stop there and have a great experience on T-Mobile. The only feature missing would be video calling. If you want to continue on yo the T-Mobile firmware, you need to skip through the setup after the U1 flash, enable USB Debugging in Developer Options, and repeat the rest of the steps from the first flash using the latest TMB U firmware.
[Samsung Galaxy Note 8 Guides, News, & Discussion] dhoang:
My mistake. I meant to say factory binary file not combination file. Sorry for the confusion. I was just following the steps from OP. Thanks for you help.

Let's say I want to go with the TMB U firmware route. I see the latest TMB firmware (Pie) on updato.com. Can I flash directly to that firmware after U1 flash?

Edit: If I follow your guide can I flash the Carrier Branded XAA U1 firmware instead of the unlocked XAA U1 firmware and stop there. Thanks again.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Flashing directly from one U to another sometimes leads to issues. Converting to the U1 first, then to another U, is the best way to go to ensure a perfect conversion.
[Samsung Galaxy Note 8 Guides, News, & Discussion] dhoang:
I think I will listen to you and just flash XAA U1 firmware and be happy with it. Less headache. Thanks again.

Edit: BTW once converted will I receive OTA?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
A proper conversion receives OTA's for the firmware they are on.
[Samsung Galaxy Note 8 Guides, News, & Discussion] dhoang:
Thank you very much for your time. I'd have one last question. What is the lastest XAA U1 firmware I can flash with patched Odin 3.13.3? Do Pie firmwares work on 3.13.3? Thanks
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Anything with the same or newer bootloader than the device currently has. The last 5 characters of the firmware are what is important. For example, 3ARC5, the 3 would be the bootloader version.
[Samsung Galaxy Note 8 Guides, News, & Discussion] dhoang:
If that's the case I can flash any Oreo or Pie firmwares then since the phone is still on bootloader version 1. Thanks
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Yes, but once you flash to a newer bootloader, you will not be able to flash any firmware with an earlier version of what the new firmware has.
[Samsung Galaxy Note 8 Guides, News, & Discussion] dhoang:
I see. Thank you for the heads up. Are you running Pie? Is it stable?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
I didn't like the OneUI so I rolled it back after a couple of days of using it to the update before Pie.
[Samsung Galaxy Note 8 Guides, News, & Discussion] dhoang:
Thank you for helping me. Just flashed the phone to Oreo. Everything seems to be working fine. Is there a way to check if I have done a proper conversion or not?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
If the next OTA shows up and installs fine, then you are good.

Hi all,

Just got a 950u off ebay. It was titled as a Verizon phone but when I turned it on it showed the T-mobile splash screen. I tried putting in my Verizon sim card but it told me to put in a T-mobile sim card.

I was going to return it but then I came across this thread. I'm pretty familiar with using Odin with my note 4 but I haven't used the modded one. And can anyone clarify the steps a little to go from T-mobile to Verizon and get volte/OTA updates? Do I need to flash to U1 first (which I assume is the unlocked version) before flashing the Verizon U? Or can I just get the modded Odin and flash straight to Verizon? How do I know if I need to do post 2 or 3? What's the difference? Is there anything that has changed from the steps on the first page?

Thanks for any help!
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Flash to the U1 first and make sure you use the OYN CSC each time. It will wipe your device.
[Samsung Galaxy Note 8 Guides, News, & Discussion] w00ly:
Thank for the reply but just to make sure I got it right, was OYN a typo? All I'm seeing is OYV
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
It can vary by firmware. Just make sure you use the CSC that isn't named, HOME_CSC.
[Samsung Galaxy Note 8 Guides, News, & Discussion] w00ly:
Sounds easy enough. One more thing before I take the plunge: I noticed that all the firmwares linked are either nougat or oreo. The phone is already on pie so will it allow me to downgrade and flash the U1 oreo fw?

edit: baseband version says N950USQU5DSC1

edit2: After doing more research, I'm seeing that I'm currently on bootloader v5. So I would therefore need to use firmware that has a v5 bootloader. So for the U1 XAA I'm using N950U1UES5DSE4_N950U1OYM5DSE4_XAA.zip and for the Verizon U firmware I'll use N950USQU5DSC1_N950UOYN5DSC1-20190306-USC-Android_9.zip
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Yeah. You can't successfully flash a firmware with an older bootloader. Using the v5 bootloader firmware to convert will ensure you don't run into any issues.
[Samsung Galaxy Note 8 Guides, News, & Discussion] w00ly:
It didn't work. I flashed U1 then factory reset then flashed the verizon U and factory reset. When it booted it still had the t-mobile splash screen and t-mobile apps. It was able to connect to verizon to make calls but no data, even though it says it's on the VZWINTERNET APN. I guess because I missed flashing the combination firmware and XAC HOME_CSC. So should I try to find XAC firmware so that I can flash the HOME_CSC for that before flashing the U1 firmware?

Sorry for all the questions but this is quite confusing. Feel like I'm getting closer though :fingers-crossed:
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Was your Verizon SIM in the device while flashing? Using any HOME_CSC will ensure you never get a proper conversion.
[Samsung Galaxy Note 8 Guides, News, & Discussion] w00ly:
The Sim was in the whole time. My "service provider sw ver" shows TMB/XAA/VZW. I thought I'd accidentally skipped a step with all the XAC HOME_CSC stuff.

What about editing things in ADB from post 2, do I need to do that as well?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Hmmm. Something didn't go right then. Did you flash all of the files in the image? Your first two should both be VZW if you flashed to U1 XAA and then to VZW U. If you are trying to convert it to TMB U, then the first two should be TMB.
[Samsung Galaxy Note 8 Guides, News, & Discussion] w00ly:
Yes, I'm at work but I think my steps were something like put the phone in download mode, load the patched Odin, flash it with U1 XAA files AP, BL, CP, and the CSC file that wasn't home. Odin passed, reboot to bootloader, clear cache, factory reset, loads into Android (didn't show t-mobile splash on boot). Reboot to download mode, back to Odin and flash AP, BL, CP and non-home CSC for Verizon. Wipe cache/factory reset/reboot. This time it shows the t-mobile splash screen. Went ahead and completed setup and was able to make calls but no data connection.

switching Note8 from AT&T to Tmobile

Hi I have a Note8 that I bought on AT&T. I unlocked the phone from AT&T and switched to TMobile network a few months back but since then I have not been able to update my software OTA or through Samsung switch. Neither tech support (AT&T and Tmob) is able to help. I though of switching the firmware of the device to the Tmobile version. Since this is my first time flashing firmware to my phone I'm confused if I should perform only the first step from this guide (Switching Carriers on Samsung Galaxy Note 8) or if I should also do one of the other 2 steps in addition ( Flashing Carrier Firmware on Samsung Galaxy Note 8 and Flashing Unlocked Firmware on Samsung Galaxy Note 8). If someone has gone through a similar situation before, can you please help me by pointing to the right steps that I should carry out? Thanks in advance.
