[Q] i9305 4.3 KNOX Custom ROM topic

To all,

I have a Galaxy S3 LTE (i9505) on Android 4.3. I wanna have it rooted, and a custom ROM as well.
What I've read about 4.3 is the fact that it got KNOX Bootloader, and that KNOX can cause problems when installing custom recovery.
How can I put a custom recovery on it? Just flash CWM in ODIN or do I need to root first, disable KNOX and then flash with ODIN? How u guys have do it (if you did it)?

Also, if you have a custom rom on KNOX 4.3, what are you experiences? Stable?


Thanks,
Daniel
