As @Dumbo53 has mentioned below posts, there is a root method by the developer @designgears and it seems that this root method does NOT trigger the knox flag.
Unfortunately, it is just for the AT&T Note 3 devices.
Maybe someone could port this root method for our international N900 and N9005 model devices?
Root de la Vega:
I wanted to share something from Chainfire's Auto-Root thread.
Chainfire has mentioned:
Using this root method sets current binary and system status to custom. Additionally, it will also trigger the KNOX warranty void status.
This device store the traditional flash counter. Nor is is possible with Triangle Away to reset the current binary status. You will need to flash a stock kernel and stock recovery to reset the binary status.
The KNOX warranty status change is permanent, and a service center may deny warranty based on this flag - even if the other flags are reset correctly. The KNOX flag being tripped may also prevent certain Samsung KNOX features from working (enterprise security features).
If this is something you care about, use a root method not based on custom kernels or recoveries, like a modified system partition. These are possible, but I don't personally make them, so look around!
So my question is simple:
Is there any talented developer who can look at the system partition on the devices N900/9005 and somehow to look if he can modify it to root without triggering the knox counter. Iaw chainfire's post, it seems to be possible, but we need a talented developer to look for this
I would be really so happy, if it can be done this way...
