You downgraded because no network? Isn't Nougat good? I too am planning to install V29A soon on my H818P

When I've this problem on my LG G4 H818P, I install F500K30c_00_0710.kdz which has been modified. After install system is in bootloop. I don't hard reset because modem. Then I install H81520o Moded.kdz, and then Lollipop or Marshmallow.
