1stly , are you still under warranty ?no longer under warranty, still remain stock 4.3 and knox not tripped
wanted to have phone root but keep the stock 4.3 rom, will update to 4.4 when it comes and look for root method for 4.4 later
Which part of my statement makes u think I assume u r rooted ? i was asking what happened to me if i tripped knox, you got talk about root, well extra info always better

As for the part locked from update to newer version, what they actually mean is the bootloader itself and firmwares but not roms?
ROM is the firmware , same as some users referred to the " phone " as the " device " Some facts about KNOX status:
It isn’t possible to downgrade to KNOX-disabled firmwares/bootloaders (An attempt sets 0×1) (even though some people state, downgrade is possible when omitting the bootloader file in a firmware package).
By downgrading from KNOX-enabled to KNOX-disabled firmware, your devices will be locked to installation of newer firmwares.
is that mean it only happens if i try to downgrade my knox bootloader to previous non-knox bootloader?

I never say Odin is not usable after rooting , only OTA and KIES update 
not quite catch your meaning for the last line[/B]
users tripped their knox to install custom recovery to go to custom rom , so what do u think ? for example, I've seen number of users on xda who have minor problems with their custom rom + custom kernel based on stock kernel will have frequently FC problems, it's something related to knox bootloader
actually not a big problem, just wanted to ask

used to mod my LG O2x, now using note 2, because knox thingy need to be more careful
really thank you for help and info, I'll do more research again
if can, i just want to keep stock 4.3 , all i want just root my note 2
Odin , OTA , KIES are 3 different thing . Rooted device cannot update via KIES or OTA but have to do it manually via Odin . My advice , stop researching as it seems to make u more confuse more and more .
KNOX is a security feature , implemented by Samsung . There are pros and cons , more to cons for people who dont use it .
Basically , what u should know
1 - With KNOX , it's not possible to roll back . Even when u r on 4.3 , it doesn't mean u can go back to earlier version of 4.3 . U can only keep updating forward . That's for stock rom . For custom rom , I was on 4.3 yet I rolled back and used SpeedWiz 2.2.1 ROM which is 4.1.2 with perseus kernel , both were long abandon . Only that rom seem to work , the others , I ended up with a corrupted EFS after flashing
2 - IF u plan to stick to stock rom , that means once u r rooted , u can no longer receive OTA or update via KIES . U need to dl the latest firmware from Samobile and update it manually via Odin .
