Lost mac adress after downgrading bios from f20 to f8 z170x g7

[OverclockerBR1]

Hello all. I recently was trying out bios f20 for my z170x g7 and ran into a bunch of problems so I downgraded to f8 using fpt dos-z170..Now my mac address is lost and I can't use the Intel controller but Killer 2400 works fine. I've read a bit online and it seems the ME firmware could have also been erased. Any help is greatly appreciated.
