Hi. I'm planning to buy S21 Ultra 5G at my trip. It is cheaper in there then my own country. I'm lucky, there and here using both Exynos SoC.
I was away from Samsung for a long time, as I remember Samsung was locking devices with CSC and Region based firmwares. That time Samsung Knox was not that expanded, as I see now it controls all system and builded top of it. I talked a bit now let me ask my question.
Is changing CSC blocks OTA? Or changing all firmware blocking OTA? I think odin is still around, Is using ODIN tripping Knox or blocking OTA? As I see Knox have 2 different fuse; one of them trips from custom firmwares&root other one trips from Odin with official firmware. Is that true? Actually my main question is, am I able to keep Knox untouched and OTAble after changing region.
Edit: It's not carrier locked.
Thank you.
csc transfer will not be blocked OTA if you transfer using samkey.
the use of odin for flash firmware does not trigger knox it is the custom recovery installation or root that triggers it.
Changing csc does not block OTA if you have not made any software modification (root & twrp).
Thank you for this post. Actually i have and exynos model too non carrier locked. My phone originally come in XSP firmware and service software provider is XSP too.. i have tried flashing XME firmware however that did not change my service software provider it's staying the same. I used odin to flash with.

I've got a Telstra-branded S8+ (code TEL according to Sammobile) and I want to flash regular unbranded firmware onto it but I'm a little confused by all this talk of CSCs and so on. Is it safe to download the Australia (XSA) firmware and simply flash the HOME_CSC file over the top of what's already there, or is there more to it than that? Do I need to worry about this tripping Knox/breaking Safetynet/disabling OTAs/etc?
I have had no issues with flashing XSA on my Singapore model Note 8. As long as it is the official firmware this will not trip Knox.
Though your original CSC will appear in the Software Information as the third CSC. Mine currently shows XSA/XSA/XSP (XSP is Singapore)
Hey All -
As a newbie I'd like to get some clarity as it's a little unclear to me still....I almost purchased a Note 8 from my carrier (AT&T) and
prefer to remove all the bloat so I wanted to get more details before finalizing my purchase. So the phone would be a Snapdragon CPU and carrier locked - which isn't a big deal for me. My goal would be to install pure Samsung firmware and be able to receive updates from Samsung without waiting for the carrier and remove the bloat.
Btw, I did a forum search and found something close but it was a Verizon related topic.
So my questions:
1) Is this possible without tripping knox?
2) What is lost between stock firmware and carrier firmware other than bloat? I'm assuming all the bands and network features keep working as before.
I'm also assuming since the IMEI number is an ATT branded phone Wi-Fi Calling and VoLTE is not lost or is CSC uploading still required with stock firmware?
Thanks!

There isn't much bloat on them anymore these days. Yes, anything you do will prompt Knox. You can disable almost any app now without rooting the phone, so no root is needed at all for that purpose. Just disable it in settings, or if not allowed on a specific app to do that, just install "BK Disabler" from the play store.

I've flashed the stock rom through Odin and fairly certain it didn't trip Knox or any issues that aspect since my company verifies Knox compliance.
With the stock rom I get my hotspot through AT&T which I couldn't on the AT&T rom, I just used the tutorial on here to flash it with no problems. I will get the updates for the U1 when it gets pushed down and have got security updates just fine. You can disable a lot of apps already though on AT&T stock
Oh and you don't lose anything other than the AT&T pre installed garbage that nobody really uses
**edit just checked and yes I'm 0x0 on Knox so it didn't trip it

Yes you absolutely can install the unlocked 950U1 firmware on your ATT device. All the 950U devices are identical and the firmware is 100% interchangeable and will NOT trip KNOX. I'm running for T-Mobile firmware on a Verizon Note8 right now. KNOX is only tripped when you flash unofficial firmware, such as custom recovery and ROM.
There's really not much of a reason to do it though. Theres very little bloat on these, and you will lose VoLTE and WiFi calling by flashing the unlocked firmware.
But if you still want to flash the unlocked firmware, follow this post:

Did you guys who flashed stock firmware get stuck with the 80% battery issue? Cause I thought about it just to get Oreo early but I don't want to lose 20% of my battery. Also have any of you tried to flash a regular update to a carrier note 8 using the update from SD card option?

You only lose battery capacity if your root a snapdragon. Not just by flashing official firmwares.

Okay I was confused. Thanks for clearing that up for me. I hope they find a fix for that eventually.
Don't hold your breath!
I bought a Korean version of Note8 N950N. I am having some problems using it in Bangladesh. For example, I can't turn off camera sound, Bixby search results in Korean language etc. Now I want flash N950F Rom. Is it possible to flash N950N to N950F without tripping Knox ? if yes, then how ?
Thanks in advance.
I think you can change CSC to Bangladesh CSC but you need Root your phone and that will trip knox.

not sure if we can simply flash another region stock rom over another.
As long as its same CPU class

I don't care about Samsung pay or health. But I need secure folder and OTA update. That's why I do not want to root/trip knox. Any other method will be very much appreciated. I tried using odin. Though both of the device have same hardware, but it doesn't allow me to do so.
One of the reasons why N950F firmware won't work on our N950N model is because of the PIT (Partition Information Table).
PIT is unique to a specific model number and storage capacity. So if you try installing N950F firmware, the information contained within that PIT doesn't correspond with what the N950N is expecting and will fail.
I am considering purchasing the Note 9 but it is an international variant. I was just wondering if there is a way to flash the UK firmware onto the phone without tripping Knox. The Note 9 is a SM-960F/DS I want to flash a SM-960F firmware onto the phone. Is this possible?
You can but It will always remain as DS which stands for Dual SIM
Check here for more and detailed info

the question dosent make sense.

The firmware for SM-N960F is the same for SM-N960F/DS!
Dial *#1234# in dialer and look at the CSC line.
If it reads N960FOXM.... then you're on the multi-CSC OXM, if not then you're on a Carrier csc and to go to the OXM csc you'll need to do a factory reset and flash the oxm CSC firmware of your choice.
Check sammobile.com for SM-N960F and look for csc - N960FOXM....
It shouldn't trip knox since your flashing Samsung approved firmwares but there might be a very small, I mean very small, chance that it might. (If done correctly it should go without an issue with knox. Just given a little warning so take it with a grain of salt.)

One thing to add, when flashing and to ensure you are getting UK settings and so on is you must be having UK SIM cards in both slots when the mobile is restarting after the Odin flashing.
Else you will stay on the international setup

I currently have a XFV Samsung Galaxy S21 Ultra.
Will knox trip/void warranty when I flash a different regional csc(XFE) firmware (using Odin) as the current one as a lot of default bloatware and Vodacom bookmarks that can't be removed.
As far as I know, changing CSC using Odin shouldn't trip Knox. If you want to be extra safe just make sure your bootloader is locked and there shouldn't be a problem.
