Help Can I downgrade my ROM?

[lotus49]

My Note 10.1 2014 is running Kitkat 4.4.2 (specifically ROM ND2).

Can I revert to 4.3?

The reason I ask is not that I prefer 4.3, 4.4.2 is a big improvement. It's just that there is a safe root exploit for some 4.3 kernels and I still haven't rooted my Note but I'd like to be able to without blowing the Knox fuse.

Although I don't know the answer to my question (I think it's yes) but it won't make any difference. It turns out that the earliest ROM for the Note included a kernel that was already patched for the exploit on which saferoot is based so I'm out of luck.
