What is anti rollback version of mm

[TheMadScientist]

So my version of 7.0 is antirollback version one. Which means mm is also version 1 or 0. But im assumming zv5 and 4 are zero and everything else so far is 1. So i can dg to zv6 or higher if i want to or is that a bad assumption

You can't downgrade if you're ZV5 or higher.

Thank you for your response.
With a long history in the g4 threads. Secure boots errors and no dl mode. I got her unlocked. Im not even worried about dg. All seems smooth and long battery life. If ibwant full root i should by a unlockable device.
I was just wanting to verify before i did attempt if it was possible.
