You can flash the U1 3BRA5 firmware using Prince Comsy's Odin...if you have issues, reboot to recovery and perform a factory reset, then back out to main recovery menu and select reboot to bootloader...then flash U1 3BRA5 firmware using Prince Comsy's Odin...

If you still have issues, downgrade to another carrier BRA firmware...maybe download was bad
[Samsung Galaxy Note 8 Guides, News, & Discussion] raejr78:
Thanks. I'll try that and update you afterwards.

Man I love seeing how active these threads are! Lots of problem solving and people willing and able to help! Love this community!
[Samsung Galaxy Note 8 Guides, News, & Discussion] raejr78:
I tried to flash the U1 3BRA5 but I had no luck. Kept getting the SHA256 fail. I used the Odin you provided with the UMS/PATCH set to 1 and still no luck. So I flashed the Verizon U 3BRA5 firmware with success, flashed the ATT 3BRA8 firmware, got 32% fail, and used the CRB7 update zip to get back to Oreo. I'm not sure why it wasn't working. I'll try to download again tonight and see if maybe it was a bad download. I did the factory reset before flashing just to be sure there were no obstacles. We'll see. Thanks for your advice before.

What firmware should i flash with my N950UZKAXAA*?

I try to flash N950U firmware but i don't receive any OTA update, even Smartswitch told me my firmware is lastest ! Any firmware N950U i flashed told me the carrier provider is XAA/XAA/VZW . Now i'm on N950U1 firmware, but I feeling this firmware is not perfect for my phone, because i don't like the model mistake of the firmware. Anyone tell me what firmware for my phone ?
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
To get T-Mobile updates, you need to switch CSC code to T-Mobile by following switching carrier section...and then flash the T-Mobile firmware.

Updates are not coming because you are on Verizon Firmware settings with VZW CSC code...

After following guide your device will be TMB/TMB/VZW
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Use Switching carrier section to change CSC code to your intended carrier... then flash that carrier's Firmware...For instance, for Verizon change to VZW in step 26, then Flash Verizon Firmware

hi all , i've bought a branded note 8 international variant (SM-N950F) and i want to change the carrier id. i was able with odin to change only the first two part of csc (in my case ITV) but the last part says TIM: ITV/ITV/TIM.

there is a way to chance the last part?
[Samsung Galaxy Note 8 Guides, News, & Discussion] cam30era:
No. The 3rd part of CSC is hard coded and can not be changed.
[Samsung Galaxy Note 8 Guides, News, & Discussion] imSh0w:
there are some malus to not change that part of csc?
[Samsung Galaxy Note 8 Guides, News, & Discussion] cam30era:
When I said it can't be changed, what I meant was there is no way to change it. It is hard coded into the device.
[Samsung Galaxy Note 8 Guides, News, & Discussion] imSh0w:
understood that, my question is : whats the difference beetween unbranded and branded csc fort the last part of the string. thanks
[Samsung Galaxy Note 8 Guides, News, & Discussion] cam30era:
It depends on your carrier. On some carriers, WiFi calling won't work, or visual voice mail. You'll have to try it and see if all premium features offered by your carrier are available on your device.
[Samsung Galaxy Note 8 Guides, News, & Discussion] imSh0w:
thanks for the answer , appreciated

ATT 3BRA8 updated in OP, shouldn't be any errors now. Make sure to extract all files, they are individually compressed to save space.
[Samsung Galaxy Note 8 Guides, News, & Discussion] junkath:
I tried this switching carrier and made it to flashing ATT firmware using steps for flashing carrier formware, however I got a problem when going to abd/platform tools using command prompt, it didn't work, but all using the odin & flashing files with matching att firmwares, they're all pass. In short, when typing adb reboot bootloader, adb shell, installing xac or changing the csc codes to ATT, I kept trying went to binar homescreen, then I did not see that IME part. So now, I still have the same problem, no wifi calling, video calling, not sure yet group sms(no incoming text from group sms).

Sorry if this has been asked, there are a lot of posts I may have passed up the answer.

I have a carrier unlocked note 8 from Sprint, I want to use it on a Verizon prepaid service. Do I need to follow carrier switching and then carrier flashing or just one of those?

Thanks
[Samsung Galaxy Note 8 Guides, News, & Discussion] junkath:
Btw, I got an unlocked note 8(sm- n950u1), with at&t sim card. Initially, I flashed with ...s3BRA8 w/ at&t variant, still wifi calling and video calling are not working. Tried doing carrier switching, no problem from step 1-10, however steps 11 - 27, right after step, my phone went recovery but does not have the option of resetting, and doing step 11, (adb already set up & on the right folder), its says my phone not listed or is not authorized, so it stuck on the boot, no option to slide the vol up/down, so I have to turn off, put it on downloading mode, wherein I go straight to step to step 28(flashing carrier firmware).

Other problems encountered: phone went to factory binary homescreen, (at least 15- 30 min waiting)but it did not load up to IME, to dial the code step 22. So, I have to skip to step 28, because it stock to boot/recovery.

So now, my note 8, which is on 7.1.1(android ver), N950U model, NMF26X.N950USQS3BA8.

Problems so far encounter w/ the phone: no video calling, no wifi calling, group sms incoming text partial or not receiving text from from iphone/android user.

Last, I think my unlocked phone does not have the right recovery mode, because there's no option of resetting, power off, reboot, mounting the phone so I can connect to adb.

Any help, will greatly appreciated

Is the phone registered on Verizon network? Have network bars, data connectivity etc
[Samsung Galaxy Note 8 Guides, News, & Discussion] drgn86:
I get bars but it says roaming and there is no data connection. When I try to register the imei it says, "phone is not compatible"
[Samsung Galaxy Note 8 Guides, News, & Discussion] kevindevonwilliams:
That's because both Sprint and Verizon are CDMA networks and a Sprint phone won't register on Verizon or vice versa.

You can use the carrier switch to achieve the specific carrier features...Try switching to a GSM carrier, I currently have a Sprint N950U unlocked and running the N950U1 software
[Samsung Galaxy Note 8 Guides, News, & Discussion] Hoshii:
Okay, I have read almost every page on this thread to make sure I am doing the correct item. Could someone just tell me before I go through with everything?

I am going to change an unlocked AT&T Note 8 so I can use it on Verizon. Basically, I need to do the Carrier Switching and then do the Flashing Carrier Firmware steps correct? After I complete those two items I will then be able to use my Verizon sim in my AT&T branded Note 8 that I have unlocked?

Sorry for the basic question, but it's been a few years since I did any flashing to my phones. Thanks!
[Samsung Galaxy Note 8 Guides, News, & Discussion] Blackhawk163:

If I change carrier with a combination file to XAA/XAA/TMB can I have Id caller and antispam or video call?
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Different features work with different carriers even on xaa firmware...I found that there are even differences in changing to the carrier code, TMB for example, and flashing XAA firmware and changing code to XAA and flashing XAA firmware...

On my SM-N950U1 I took notice of features while my code was XAA, changed to SPR by the SIM, vs changing the code to the carrier version of SPR...when starting on XAA and having SIM change to SPR, I had to manually force some carrier features...But when I changed the code to SPR with the guide and flashed the XAA firmware, some extras were already included...I still had to manually turn on volte though...

But T-Mobile and Sprint were the best on XAA firmware with having carrier features on...
[Samsung Galaxy Note 8 Guides, News, & Discussion] serchfx:
Ok with n950u you recommended change to n950u1 or only change carrier to XAA with file combination
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
You will get caller I'd and anti-spam on SM-N950U1 firmware but video calling is only on SM-N950U firmware...I'd try the different ones and see which one you like best
[Samsung Galaxy Note 8 Guides, News, & Discussion] dazemc:
Or root........
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Yeah...root is definitely an option as it gives the ability to edit more...lol...they could even run my N950U1 ROM...although, the carrier features work out of the gate with Carrier firmware and U based ROMs...

I have a Verizon Note 8 and am currently running the unlocked S2BQL2 unlocked build. I am in the process of downloading the U3BRA5 unlocked build. Once I've upgraded to that, are there any custom roms that I can run? Or are we still unable to based on my bootloader being locked?

Also, can anyone tell me what benefits there are in upgrading to the newest U3BRA5 build from where I am at?

I am using the unlocked builds so that I can charge to 100% and be able to use my hotspot on my grandfathered unlimited plan.

Thanks in advance for any input you all have. I hope you all have a blessed day!
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
SamFail V3 is out...so you can root...

If you go to OP and look at links I have a ROM based on SM-N950U1...2BQL2...that can be ran with V3...I will be updating with BRA5 build soon...

Some say that better connectivity comes with BRA5 but mostly added security and it is the Jan patch

But rooting on BQL2 is less steps
[Samsung Galaxy Note 8 Guides, News, & Discussion] Stevieboy02008:
I will download that one and flash it now. I'm on Verizon
[Samsung Galaxy Note 8 Guides, News, & Discussion] Exdaver:
Few questions...

I'm trying to switch my N950U from T-Mobile to Sprint. I already paid to get my phone unlocked through the app and it works on AT&T, but can't activate on Sprint.

What do I need to do in order to activate the phone on Sprint? Would flashing any of these help me use my phone as byod?

Does flashing any of these things trip knox?
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Flashing does not trip knox...

Sprint is currently not allowing other carrier Note8's on their Network, however, if you use switching carrier guide and change csc to SPR and then flash the Sprint Version of Firmware, you may be able to go in and have them do it anyways...it is the iemi that they allow or disallow....they have done it for me in the past but I had to call customer service and have them force the iemi to their whitelist...it took a while but they did it....

The other carriers accept the devices...as is...

You just have to keep calling them and state thast it is loaded with Sprint and have your Sprint SIM in...

Sometimes the activation on the phone will bypass as long as everything is sprint...Sometimes not
[Samsung Galaxy Note 8 Guides, News, & Discussion] Exdaver:
Hey BlueFox! Thanks for the quick reply. I had a few more questions and pmed you about it.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Stevieboy02008:
Ok my question is. On the first Odin I just need to flash the AP only?
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
The combo first in ap then Home csc in the csc section of Prince Comsy's Odin
[Samsung Galaxy Note 8 Guides, News, & Discussion] ChadH42:
I have a Verizon N950U. I have switched carriers to Total Wireless (CSC = TFN). I have executed the steps in the OP to switch XAA/XAA/VZW to TFN/TFN/VZW but the phone always winds up back with XAA/XAA/VZW. I can't figure out what I'm doing wrong. After I flash the Canadian CSC file & run the adb steps and then select XAC & press Install I get a screen asking if I want a Full Customization or a Network Customization. Has anyone else gotten this screen after selecting XAC then pressing Install??

I bought a Cricket SIM card because I was told my Sprint Note 8 would work on their network and it also says on Cricket's website it's compatible. However, after inserting the SIM card, the top right says "Invalid SIM Card." Will using this carrier switching / firmware unlocking method allow me to use the Cricket SIM card? If it has an AT&T carrier firmware, could I flash that since Cricket is AT&T?
[Samsung Galaxy Note 8 Guides, News, & Discussion] Exdaver:
Tried to flash AP the combination, but odin returned "FAIL! Model dismatch fail". My build number ends in BRA9, so I assumed I would be using: COMBINATION_FA71_N950USQU3ARA3

HOME_CSC_OYV_N950WOYV3BRA5

Can someone please advise?

Edit - Nvm. I can't read instructions it seems...
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Did you use regular Odin?
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Full

You can also factory reset before flashing combo in regular odin
[Samsung Galaxy Note 8 Guides, News, & Discussion] kevindevonwilliams:
Your Sprint Note 8 needs to be carrier unlocked first before you can use a GSM Sim hence you get "Invalid SIM Card"..

What baseband is your phone on?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jmdomini:
Enable RCS on Sprint with unlocked?

I know that it's not possible to enable RCS on Samsung's Messaging app on the unlocked U1 firmware with Sprint, however I thought I had read it would work with Google Messaging. Seems that isn't the case, if I go to the chat features menu and try to enable RCS it just clocks forever. If I flash the CSC from the Sprint firmware that gets RCS working, but then I lose "Caller ID and Spam Protection".

So is there any way on Sprint with the unlocked firmware with Google Messaging (or any messaging app) to get RCS without losing unlocked features?

Thanks!
[Samsung Galaxy Note 8 Guides, News, & Discussion] Exdaver:
Yeah - I realized, after I read through the instructions one more time. I've successfully done the flashing! Just called Sprint and got through to the tech team. Just got a "special" ticket number for forcing my imei into their system as my phone is a "Sprint" phone now!

Thank you!

Flash combination file "COMBINATION_FA71_N950USQU3ARA3" then unlock device with Z3X box :good:
[Samsung Galaxy Note 8 Guides, News, & Discussion] mobbdeep:
Is Z3X Box something I have to purchase and is it physical or online?
[Samsung Galaxy Note 8 Guides, News, & Discussion] kevindevonwilliams:
Technically yes, but Google around you might find a cracked version ;)
[Samsung Galaxy Note 8 Guides, News, & Discussion] mobbdeep:
Sorry, let me specify what I was asking. Is Z3X Box program based only or is it a physical item? I was seeing on the Z3X Team site it was a physical item.
[Samsung Galaxy Note 8 Guides, News, & Discussion] kevindevonwilliams:
Both :good:

But there is a few cracked version around, so Google is your friend :cool:
[Samsung Galaxy Note 8 Guides, News, & Discussion] mobbdeep:
I'm having the same issue. What exactly do you mean, regular Odin? I used the Android File Host - Odin3_v3.12.7 / _v3.12 (PrinceComsy) link you provided.

---------- Post added at 01:27 AM ---------- Previous post was at 12:38 AM ----------

Edit: I didn't enable developer options.
[Samsung Galaxy Note 8 Guides, News, & Discussion] kevindevonwilliams:
What exactly did you do?
[Samsung Galaxy Note 8 Guides, News, & Discussion] mobbdeep:
I did everything in the Carrier Switching part but I want to confirm..

When I got to Step 23, chose XAC > Install, it automatically selected SPR (Sprint). However, when I got to Step 25, I did:

echo "ATT" > /efs/imei/mps_code.dat

Is this what I'm supposed to put where it says XXX as carrier code? I am wanting to use my Sprint Note 8 on Cricket and you recommended to flash that file first for my baseband which I've done if i did steps 23 and 25 correct. Once I do the carrier switching, do I need to do Flash Firmware too and if so, which carrier? Once this is done, I will be doing the Z3X Box if that's what I'm supposed to do next.
[Samsung Galaxy Note 8 Guides, News, & Discussion] kevindevonwilliams:
You had to flash combination file and unlock the device with Z3X software before proceeding with carrier switching.
[Samsung Galaxy Note 8 Guides, News, & Discussion] mobbdeep:
I'm confused then. I flashed the combination file you mentioned and used BlueFox's tutorial. Do I only only do up to Step 10 on his Carrier Switching steps, unlock with Z3X, then finish the rest of the steps? Or is there just steps for combination file itself?
[Samsung Galaxy Note 8 Guides, News, & Discussion] kevindevonwilliams:
Follow these steps:

1.) Download Odin (Regular Odin)

2.) Download Combination File

3.) Google a cracked version of Z3X

4.) Put phone in download mode, and flash Combination file in AP using Odin

5.) Unlock device using tool.

Now your phone would be unlocked to all carriers including Cricket (AT&T)

Afterwards proceed with carrier switching which is changing the CSC & flashing ATT full firmware.
[Samsung Galaxy Note 8 Guides, News, & Discussion] mobbdeep:
Okay so I will do those steps including unlocking with Z3X. I then proceed to carrier switching steps OP provided? If I do that, isn't steps 1-10 flashing the combination file?
[Samsung Galaxy Note 8 Guides, News, & Discussion] kevindevonwilliams:
Yup step 1-10 is flashing combination file as stated in the guide, once you unlock with Z3X then proceed with changing the CSC.

[Samsung Galaxy Note 8 Guides, News, & Discussion] jmdomini:
To answer my own question, and help others that may run into the same issue. It seems that when you go into the IMS options with Shortcut Creator and turn on all the switches, there's one item under RCS that should not be turned on called "OPTIONS". Once I deselected it, Google Messaging enabled RCS almost immediately.
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Yes...you can flash csc from carrier

Are you using the correct version to your latest bootloader? Are you using proper Odins for each method? Did you perform factory reset before flashing combo? Are you using USB3 or 2?
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
The fingerprint issue on root is due to using the wrong root files...you can use the official SamFail Firmware or the updated Odin Files from my ROM thread...
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
They are the same unless Sprint has added a userdata file...if not the version is same...I think the main reason the branded versions are to keep servers balanced...while having the ability to add branded options....flashing N950U carrier CSC will enable VoLTE
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
The problem is that you have flashed 3ARA3 bootloader and your system is still AQI5....at this point might as well root using SamFail V3 completely then try unlock again
