I believe this works but you will lose your recovery,

As Savoca states above...
Flash that you will either:
A) Get ZVA - Loose recovery and have a loki-proof aboot
B) Fail - Nothing happens
C) Be forced to run a .tot if the ROM doesn't boot. Since you will loose your custom recovery if the flash does not fail.
It's bad practice to just go flashing up something in which the origin, author NOR true use is even known or posted.
If Savoca posted something and said, "I made this and it should work, I did it, this is what happened and why" then sure, that's one thing BUT the mystery zip, while the intention of sharing was good, it's only adding more noise and unknowns to the equation for people to sift through.
Savoca has clearly and plainly stated in the OP what needs to be done and how to do it. These other mystery (if it'll work or even what it will do) work arounds honestly have no place in this thread but that's just my opinion and you know what they say about those.
