hi to all so i have been searching about knox tripping i have found something system property ro.boot.warranty_bit which is what the knox status samsung apk looks at when checking to see if knox has been tripped i was woundering if someone could help me of pulling this file from there samsung s8 or anything on firmware 7.0

im still new to this developmentt of android devices

The new Knox implementation is different from previous iterations, when Knox is tripped, it permanently triggers an e-fuse, there is no way to revert that, Knox can only be faked to show intact Knox with a custom kernel.

i see but then you cant reset the counter tho and flash back stock to see if knox been triped tho

You don't need to flash anything to check if Knox is tripped. Just go into download mode and it will tell you if warranty is void 0x1 = tripped 0x0= Not tripped.
You'll never be able to fix the e-fuse as it's in the exynos socket chip so it's litteraly impossible now.

it could be done something through the bootloader and kernel i just need them dumped files and ill look into it

In computing, eFuse is a technology invented by IBM which allows for the dynamic real-time reprogramming of computer chips.
By utilizing a set of eFuses, a chip manufacturer can allow for the circuits on a chip to change while it is in operation

The Nintendo Switch and Xbox 360's bootloaders for instance will check the amount of burned fuses before attempting to install new firmware

You can reset knox by changing the motherboard.

Is there actually any proof that it's an e-fuse? I have seen a lot of conjecture, but no real evidence. It could just be a section of memory that is normally read-only.

Either way, we currently have no way to reset it.

It's not anything physical as far as I can tell, it there's plenty of xda articles, but there is definitely what's called an e-fuse involved with tripping knox

Ok, can you provide a link to something that actually proves that it's an efuse? I have never seen any actual evidence. People merely calling it an efuse is not evidence.

Older phones which had Knox did not have e-fuse which is why in phones like the galaxy s3 you could revert Knox to 0x0, from the s5 or s6 they implemented Knox with e-fuse hence why there's been no way to revert it since then, only way was too fake Knox 0x0 through custom kernel

Just to add, chainfire confirmed a long while back thay e-fuse was involved

None of this is proof. Most of what you posted just explains what an efuse is. Where is the actual evidence? Chainfire said he does not know whether it is an efuse or not, and if you read the top post at this link, would suggest that it is not an efuse...

They've used the word fused here, now I know this doesn't prove anything but it more than likely is pointing to it considering the language used, having actual proof would mean a Samsung dev releasing closed sourced info.

Or perhaps a savvy engineer with a microscope could show us real evidence of an efuse.

That is not what "fused" means in that context. Listen, I'm not saying that it definitely isn't an efuse, but to assume that it is without proof is a bit foolish. If it is an efuse, then can you explain how the Exynos processor-equipped variants HAVE been resettable from 0x1 back to 0x0?

Old Samsung phones have been able to reset Knox, as far as I can tell from s6 which i owned, once Knox was tripped that was it, the only way to have 0x0 is though faking it through at a kernel level, that's why 100% of custom kernels available for the exynos variation have fake 0x0 flag. If you've seen otherwise please show me that, as far as I know no one with 0x1 Knox flag on exynos has done that, i have the exynos variant btw.
