So... mini jack stopped working nor lightning menu button

Hey folks!

So basically, my mini jack stopped working at one point + menu button on this side stopped lightning up.

Button itself works without problem.

Bought a new daughterboard, replaced it aaaand.... guess what - everything works like before - still no reaction from jack and no lightning is up.

What's going on?

What might be the problem?

I'm strugelling with this for some time now... I WANNA LISTEN MUSIC!
