[Q] Installing KK Bootloader - what is my D802 version?

I've been wanting to install CloudyG2 v3.3 to my D802 and I figured that I'll have to flash KK bootloader.

Where can I find my current D802 rom version (30a?30b?etc...)? - I understand that I need 30a/30d to install the AutoRec KK bootloader.

Should I event try to find it, or can I just flash the latest one? I'm a little bit confused...

P.S - Yes, I've read the D802 NOOB manual.
