I have a Canadian Note 5 (W8) that was originally locked to Bell which I unlocked and am now using on Rogers.
Whenever I flash a stock ROM in Odin, the phone goes for the unlocked CSC (XAC) instead of the Rogers CSC.
How do I force it to use the Rogers CSC? This is because I want to make use of features like VoLTE or WiFi calling which Rogers provides, and they're not available on the XAC CSC.
Thanks.

I used the patched Odin from https://forum.xda-developers.com/ga...ock-sm-n960u1-usa-unlocked-firmware-t3833566/ and SamFirm to download the firmware.
I tried going from stock Verizon to N960U1 TMB and then to N960U TMB (as I've read in a few threads). Going to U1 TMB works fine (no carrier branding anywhere), but going to U TMB (or U1 ATT to U ATT) just goes back to Verizon firmware...
Any ideas? Been at this for two days.
It's been 8 years since my last Samsung phone (S1 Vibrant) and I just got a SM-N960N Korean Unlocked variant. Spent the last decade with the Nexus 5 and LG V20.
Planning to use Cricket (ATT MVNO) with it in San Francisco, CA. I know that not all the bands are supported but what is the deal with the csc?
Does it only effect wifi calling and voip or are there other carrier customizations I'm forgetting?
It wouldn't change supported bands of the modem?
And the detonator tool for changing csc doesnt work for the N960N, if I needed to change it can it manually edit it using a root file manager?
Also, I'm confused by why rom devs link odin flashables while not touching on them in the instructions.
Is it expected to odin flash the model's bootloader and modem before or after following instructions for wipe and rom install in twrp?
Thank you! It is nice returning to the phone that has almost everything
Verizon is my carrier and I am upgrading to an S10 from an S7. I bought a new S10 loaded with the first Verizon version of Android 10, G973USQS2CSL1. I want to get rid of the bloatware and go back to Android 9. My plan is to flash the U1 firmware, G973U1UES2BSIV, using all 4 of the U1 files. Then flash the Verizon CSC file from this firmware, G973USQS2BSIV, so I can get the "Advanced Calling" for Verizon. I was going to try to do that on my S7 but never got around to it. Here's a thread I created on the S7 forum that said that's what I would need to do to run the unbranded firmware on the S7 but also have Verizon's Advanced Calling (wifi calling, video call, hd calling). https://forum.xda-developers.com/galaxy-s7/help/install-verizon-advanced-calling-g930u-t3997525
I noticed the S10 Verizon firmware now has a 5th file, a USERDATA file. Will I need to also flash that?
I wanted to point out, my new phone is currently locked, but Verizon automatically unlocks it after 60 days. https://www.verizon.com/about/consumer-safety/device-unlocking-policy Will it be a problem if I flash the unbranded firmware on a phone that is still locked? Since Verizon is my carrier, I will obviously be using a Verizon SIM card.
Thank for the help.
You can flash any firmware to your phone as long as it's for the U or U1 models as the "U" means Universal. Bought a phone from AT&T? Flash the Sprint or T-mobile firmware without issues. Same for Verizon and other U.S. carriers firmware.
Flashing the unbranded firmware will get rid of the bloatware, but will also get rid of other features like wifi calling, advanced calling, etc. The user data file is just all of Verizon's bloatware and info crap.
As for going back to Android 9, you can do that as long as you're still on the v2 bootloader. If you've upgraded to the v3 bootloader via OTA, you won't be able to return to Android 9.

I'm on v2 bootloader. Have you heard of flashing the VZW CSC file on top of the U1 unbranded firmware? Apparently people have done it on older devices, like the S7, that only took the 4 files when flashing. I'm trying to run unbranded firmware but still have the Verizon Advanced Calling (wifi calling, HD calling, video call).
Okay if you're on bootloader v2 then you can go back to Android 9. I haven't heard of flashing the carrier CSC file with the unbranded U1 firmware. It might work or might also brick your phone.
How can this be done? I'd like the stock UK one (BTU service provider I believe?) as currently it's showing as VOD/VOD EUX etc.
Will my data be wiped? Is it really worth changing and going through the hassle? I've always had stock firmwares either out the box or flashed on Odin by myself but this time it didn't remove the carrier stuff.
I did initially flash the latest stock BTU firmware (all 4 files including CSC not home CSC), yet was still met with the carrier apps and the service provider info says VOD, I'm on Three the phone is unlocked but from Vodafone

csc detect from SIM CARD .
I have a verizon branded s21 ultra. Switched to tmobile and flashed the u1 firmware. Flash went fine, rebooted, put in tmobile sim, but still shows VZW/VZW/VZW. Cannot receive tmobile ota's. Model number says U1. Any help is appreciated.
It should show TMB/TMB/VZW correct?
I remember going through a similar issue on A20. The steps are probably the same https://www.droidwin.com/change-csc-codes-samsung/
Even if you can't change the CSC, you can always flash the Tmobile rom (zip) using SamFirm and install them manually https://www.xda-developers.com/download-samsung-updates-free-tools/
Tried flashing tmobile software using Odin. Booted up to verizon splash screen and still showing VZW/VZW/ VZW

SM-G998U1 isn't the model number for the TMobile Branded device, it's the Unlocked variant. You can download the TMobile firmware here. You may not receive TMobile's OTA's even after you flash TMO Firmware since your Primary CSC will always be VZW.

When I flashed the TMB firmware, it still boots to Verizon splash screen and still shows VZW/VZW/VZW even though there is a tmobile sim installed
Try changing the CSC to TMO by entering the following code on the Dialer TouchPad. *#272*YOURIMEINUMBER# In the string replace YOURIMEINUMBER with your actual IMEI Number. You may see a list of regional CSC's. Select TMO then select install. I'm not sure this method still works on the Verizon device or after the latest updates but it's worth a try.
