This is reserved for W8 only! If you have any other model, this will not work
Whats different from the other other upgrade threads? This one doesn't block you from going back to 4.3, it allows you to retain knox 0x0 and it's safe.
Just tried this, worked perfectly. I came from X-Note 7.0 and did this on my friends Note 3 and he was on stock. I already had knox 0x1 but i was alble to keep his at 0x0.
As of now, this has only been tested on W8 model as it takes the files from the Telcel firmware (mexico). You can use this method on any W8 model,
the only thing you will have to change is substitute my modem (CP) by the modem from the latest 4.3 firmware of your carrier. It seems as the MD5 from all modems for all canadian carriers match exactly, so the model for rogers also applies to Bell and Telus
If you are coming from a non-canadian W8, you can extract your modem directly from stock firmware. Here is how:
Upgrading to Kit Kat and downgrading back to 4.3 does not trip knox, and rooting using my instructions either. Be sure to turn off reactivation lock before flashing this. This method gives you an easy way to official 4.4.2, once you're there, you can flash any 4.4 rom.
Also, and this is an important factor for a lot of people, this doesn't block you from going back to 4.3. If ever you want to go back to Jelly Bean 4.3, just flash back to it via ODIN
Download all the files, PIT, BL, AP. CP and CSC, the flash via ODIN 3.09. Then flash CF-Root and CWM if you wish. I did not check re-partition in ODIN, it worked for both of my Notes, most users didn't check it either, but a small few said the flash failed until they checked re-partition, either way, it should not brick your device.
Here are the links to the files:

Don't use included ODIN in CF-Root, use 3.09 and flash via AP

Thanks to Oogar
for a more complete version of this process. This method does break WiFi and NFC so head over to his thread for the patch and a proper thanks
