Looks like Samsung did us a favour and didn't include that obKNOXious thing in the new firmware That's great news. I wonder if it's because of missing hardware or simply because they don't care enough about their old devices (spoiler alert: they don't) to add features from their newer ones.

If they had added KNOX however, that could lend more credibility to the theory that even on new KNOX-enabled devices the flag is NOT an efuse and that it's actually stored somewhere in the emmc. Oh well, I'd rather enjoy my tablet unrestricted than be concerned about triggering a stupid flag. Thanks for checking guys

It is possible, as with the Note 3 3G version, Knox was included but there is no counter. It seems only on the 4G Qualcomm variants that the "Knox counter" is apparent. If you checkout the N9000 part of the Note 3 forums this seems to be true. I wonder if it is CPU specific? They only trigger a physical change on the CPU that isn't Samsung's own...

I've been looking into this matter quite a bit lately since I also own a Note 3 (Qualcomm LTE version - N9005) and from what I've gathered, the Note 3 N900 does have a KNOX flag and counter. However, a while ago a special service bootloader was leaked specifically for that variant, which apparently wipes this flag altogether and allows users to flash custom roms freely and downgrade to earlier software versions. The security implementation likely differs between Note 3 variants but I'm not really convinced that the flag is stored in an efuse on the Qualcomm chip. Even if that's the case though, I think Samsung so far have failed to add efuse-equivalent technology to their Exynos chips and this means that the only way for a KNOX flag to exist would be on the device memory, probably somewhere within the sboot partition or a partition of its own maybe. I don't think they would go into so much trouble to add all these security features to an almost 2 year-old device that probably also lacks the proper technologyNot to mention that many original Note 10.1 devices are not covered by warranty anymore (ie outside the EU where warranty is valid for only a year in some places) so they wouldn't really care about users voiding their warranties at this point and thus no need for the KNOX flag.

We got lucky with the Note 10.1 actually. Only a custom flash counter that's easy to reset thanks to TriangleAway and now we also get KitKat. Very nice
