@Riot question about "remake" mechanics invloving demotion/ promotion/ protection

i am curious as how a "remake" works if you are at 0 LP, or in your promotion series

because i have heard on the forums that it counts as a loss for both

i am also wondering how it works for your "protection from demotion" games after reaching a new teir/division.

will it count against the 3 game or 10 game protection?
