SONY A7R2 E FRONT CURTAIN STUCK - No working!!!

My A7R2 front curtain not working, it apparently stuck and can not release after shooting in Poland at -5˚ C.

I try to removed battery... still like that.
So after try to research in some forums without luck, I tried this quick fix.

I'm planning to sent to Sony center anyway to avoid future issues but in the meantime will keep my settings on silent mode.
