...???
I didn't get any updates.
I purchased mine with 4.3 out of the box.

NOTE 3 (4G/SQD 800), 32GB, Black.

As far as I know, there is no "eFuse" in the device... the KNOX feature is 100% software just like "Flash Counter" or TriangleAway as was introduced in earlier "Galaxy S" devices.

Right now there's no way to "flash" things to the Note 3 without installing a custom recovery (Odin), and there's no way to install a custom recovery without tripping KNOX. And once tripped, there's no way to revert the KNOX counter.

There is this, one way of r00ting without tripping KNOX:

I think once we can revert KNOX, or flash without tripping things should get interesting.

I'm really looking forward to this setup:
-custom recovery, busybox, r00t
-chroot ubuntu (or dualboot)
-remove (heaps) of bloat
-MOD collections (fix phone, sms, mms, gallery, multiwindow, status bar transparency, change touchjizz colours, torch on lockscreen, fix headset button actions, etc etc)
-install favourite apps (SwitchR PRO, Kii PRO, Apex PRO, 500 Firepaper, Flipboard, etc etc)

Honestly, even though an upgrade, there's lots of frustrating things with this phone.
For starters, when I'm gonna make a phone call from someone's message list... hitting the volume buttons (by accident/altering volume).... it doesn't change the music volume, it friggen zooms the text messages up by many folds. Stupid.

Its attention to detail. This is why Apple rules and Samsung sucks.
If only Blackberry strived on, and MeeGo wasn't aborted : (

...HONESTLY here's what this community needs.
1) Stock AOSP Android.
Modify it to run on Linux kernel. Port over the necessary frameworks from Linux such as (proper) C++, Qt, Python, etc etc etc.

2) Then support devices which have proper documentation (OMAP is dead, Tegra is no-go, Exynos is frustrating, Snapdragon only option)

3)...and are not hardware-bootloader locked (Motorola is no-go, HTC is frustrating, LG is okay, Samsung is workable as long as its a flagship, SONY is the legend).

4) ???

5) Profit.
