Default [Q] C6902 USA specs root

I have a C6902. I've rooted it and my firmware is .534 .

----If I OTA update, will I lose root?----

Apparently I've been misreading the how-to's.

Also, if this loses root, do I perform the following :
Use flash tool to flash ftf downgrade to .534 euro spec.
Upgrade to Latest firmware
check root...
