Default [Q] knoxraid v2 kitkat rom recovery for SM-N900A

Do you need to install first version of this before v2 or can you just flash v2 with new safestrap version.

I know that v1 didnt work with safestrap making it difficult to flash back to 4.3 rom. If using this new safestrap should I be able to access my 4.3 recovery files? Please let know ASAP. Very interested in having kitkat. If v2 and this version of safestrap allow me what I need I'm going for it.
