I'm asking because I was trying to help another XDA member that is having trouble with his s3 that's running stock AT&T 4.3 ROM.
I rooted with Chainfire autoroot, when it booted Knox was blocking and force closing Super SU. I flashed TWRP with Odin, Knox is still there and no root access, but now you have a custom recovery and can flash a custom rom that has Knox removed. I'm running this:

Also, I believe that you needed to update supersu to the latest version and then update the su binaries to disable knox. The latest version is 1.89, but it's currenly only on XDA, not in the playstore

As I said before after I rooted with CF, Knox blocks SuperSU or something and it force closes. No way to get into it and update binaries, and yes I was on the latest version. There are many people reporting this on the CF autoroot thread. This is the only way I was able to obtain root.

I'm well aware the bootloader cannot be downgraded. It also seems as long as you are on the new bootloader you can not use the normal unlocking methods. That's the reason this thread was started to begin with.
