[Q] How to re-root once MK6 4.3 installed

OK, think I must be being a little bit blind around the forum, but cannot seem to locate how and links to perform a root once I update to 4.3

I'm running 4.1.2 and am currently rooted (I used CF-Root-SGS3-v6.4 since forever and always seems to work), which seemed to work fine on 4.1.2. However, reading all over the place about rooting being different on 4.3, but as I said, just cannot seem to find links and info on how to do it on the latest

I know I can easily install the 4.3 update using ODIN to replace 4.1.2, but would then like to re-root once this has been done

Any help and links much appreciated

Cheers
Albie
