Is it possible to flash firmwares freely from a samsung device?
I just purchase an s23 phone but the firmware is from taiwan.

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)
Will I trip Knox? I want to use Samsung Pay.
Hi, I want to flash a ROM from a different region on my Note 9. Will Knox be tripped if I use Odin to flash a stock ROM from sammobile?
I know Samsung's have either the Exynos or the Snapdragon chipset and it's not possible to flash a Snapdragon firmware on a Exynos phone.
However, I have an Exynos Note 9 (SM-N960F) and I'm planning to flash another stock Exynos ROM from a different region (also model SM-N960F).
My question is, will Knox be tripped if I use Odin to flash a different region, stock ROM from sammobile?
Knox won't trip if only flash original different firmware
Has anyone tried it?
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 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.
