Question Changing CSC will trip Knox? - Samsung Galaxy S21 Ultra

I have a Canadian S21 Ultra Snapdragon (SM-G998W) and I want to change it to the American version (SM-G998U1).
If I perform this process via Odin, are there any contraindications? Will trip Knox?

I went from 998U to 998W and it was fine.

Did the process via Odin and Knox was ok? That's great, I'll do it on mine!

Note 9 N9600 SDM845 HongKong Version to N960U1 firmware ?

Hello,
I have a Note 9 N9600 SD845 HongKong Version, I am using Lyca Mobile sim( Tmobile MVNO) with it .
I have gone through this forum and could not figure out if its possible to install the N960U1 firmware on N9600.
If yes, will it activate all the tmobile bands on N9600 ?
I also have a ATT unlocked note 9 N960U, I have flashed it to N960U1 successfully using Odin. Is it the same process for N9600 ?
Thanks in advance
I there, I have the same phone model and the conclusion that I made was that you can't just flash the u1 firmware like how awe are used to. I had to root mine in order to install tmb software. I then had 4g Lte and wifi calling, but before you root look at what you may be missing out on. It is usaully stuff dealing with knox i.e samsung pay, secure folder, etc.

Unless you flash the official Samsung software using Odin, you will not be able to install OTA updates. But from my understanding you can't flash USA U1 firmware onto the Hong Kong/International N9600 Note 9. The bootloader will only accept firmware for their respective models. All U.S. Note 9's can flash any of the carrier versions or the unlocked U.S. firmware, but you can't flash the international N9600 firmware... and vice versa.

Question about Verizon Note 9 on AT&T

Hi guys,
I recently switched from iPhone to Android, and I love it.
I purchased a carrier unlocked Verizon Note 9, and I'm using it on AT&T. I was wondering if flashing it to AT&T firmware would require rooting the device and would that trip Knox hence disabling Samsung pay and other features?
I have also heard that rooting Samsung phones voids warranty and I'm just trying to avoid that.....
I love the phone the way it is, but I want to use WiFi calling and other AT&T apps. I have done my research regarding whats needed to flash the firmware, but nowhere it says the method is actually "rooting" the device. I just want to double check before I flash.
Any feedback would be highly appreciated.
Thanks in advance.
You don't need to root it. Download the ATT firmware with the SamFirm tool, then use the patched ODIN 3.13.1 to flash it.

Well, I don't know. You have to provide more info. How is not working? At what point does it fail? What firmware did you download? How are you trying to flash it. What steps are you taking?

Help needed with new phone.

So I just bought my Note 9 and have been away from Samsung for a while so I'm not really up-to-date. I have the N960F DS model with COS (COSMOTE Greece) CSC still on Android 8.1.0
How can I change my CSC and flash the latest EUR CSC (Greek CSC) Android 9 update?

If I flash the EUR CSC ROM through Odin even though I'm on the COS CSC, is KNOX going to be tripped?
Official firmware, no tripping of Knox

What about updates? If I flash it and perform a full flash, am I going to continue receiving updates under EUR OTA?

For sure you can't downgrade bootloader. I don't think you could change international unlocked version to US locked version. I'm not not sure though. Have you asked in the patched odin thread?

You can't change G965U to G965F. I guess it should be the same for note 9
1. You cant. YOU MIGHT SUCCEED TO FLASH IT with the patched Odin, but that will most certainly brick your phone. These are two different phones, PERIOD.
2. What you can do is FLASH SM-N960U1 firmware with XAA CSC to your phone, and have all the AT&T stuff away. This too needs the Patched Odin.

One UI 3.0 can be loaded on SM-F916U1

I'm using an unlocked U1 on T-mobile US and just used the google dialer to switch CSC to XAR (Which I don't think you HAVE to do). Just use frija and download SM-F916W region XAC and use Odin patched. Up and running with no issues.
**updated i actually used model SM-F916W region XAC in Frija.

did you have to wipe your phone? Same on T-Mobile and getting antsy waiting
Is there any drawbacks whatsoever for changing your CSC?
Or let me rephrase, do you still have 5G, Wifi Calling, samsung pay, etc.?

Which CSC did you use when searching in Frija? XAR returns no results for the SM-F916W.
XAC?
After looking on Frija I'm seeing XAR is for SM-F916U1 and it's US based Android 10. Not sure how you got Android 11. If you meant XAC there's no option to change the CSC to that.

My apologies i was running on very little sleep. I did indeed use XAC in Frija. So I suppose you could try leaving it on TMB and flashing since i flashed the XAC version for SM-F916W over XAR on my U1. I do have a bunch of extra dev options though that i'm not sure would be exactly the same. I will confirm later but so far, I haven't found a dialer code on XAR that works to change CSC on version CTLL with XAC. But your sim will automatically flip your network CSC to TMB regardless. I'll update my previous posts thanks for the catch.

Like i mentioned in my post above, so far, I haven't found a dialer code that opens up the CSC menu on the new version. I'm going to try again shortly but your sim will automatically set your network to TMB. I can say that VOLTE and WFC works much more efficiently for me on the new version. You just have to wait for setup to complete and the WFC option will appear as usual.
ODIN allowed you to flash SM-F916W firmware on a SM-F916U1 model? Typically cross flashing between models fails when using ODIN and even if it let you, you'd probably be soft-bricked.
This does work. I have tried it. My fold 2 was bought from Samsung unlocked. It now shows the device as SM-F916W. I am with AT&T and 5g doesn't show up but everything else seems to run just fine.
I was also able to go back to u1 firmware with CSC XAA .

Yeah the patched ODIN 3.1.4 did work in this case. I did some checking of the partitioning among various regions/versions and the canadian version didn't really require any changes so i thought i'd take a chance. I do have 5G so that tells me you need to apply sales/network CSC of something that isn't carrier locked prior to updating and everything should work ok. That's speculation and my personal experience.

Hey! So, I have SM-F916U. I flashed SM-F916U1 firmware to get rid of the AT&T Bloatware. Everything is working fine but my Samsung Pay shows USA Offers but I live in India.
Going by the same logic as you mentioned, Can I flash CSC of SM-F916B (India Version) to get Samsung Pay Indian Offers?

I'd be hesitant to do anything with a non-unlocked variant.

This isn't surprising at all. Since the Galaxy S8 and Note 8, the U models and the W models have all been cross compatible with firmware. They are actually the same exact device, and the W only indicates it's running Canadian firmware. Just like the U1 indicates it's non-carrier branded and U indicates it's a carrier model. No issues cross flashing at all.

916B and 916U are not the same devices. There are hardware differences, so you can't crossflash firmware.

Flashing firmware doesn't do anything to affect the locked or unlocked status. Many, many people here have flashed U1 firmware on locked U devices over the last few years.

I honestly have no idea. I'd check some of the other Samsung forums, like the Note 20 or Note 10 forums.you may find an answer there as they are more popular devices.
I actually went and flashed my u1 to this version .. everything else works as it should but so far my only drawback is that my samsung sofi account has been deleted after it updated to samsung pay Canada...
Edit: although it samsung pay Canada all I had to the was verify my samsung password and accept samsung pass terms and I was good to go everything is there and works as it should.
