It still does not work(still layer only on first page in Mk IV). What am I doing wrong?

A typo in pack-lyr.mkiv for the \dodoflushlayer macro.

In MkII a line of the macro is

      \doifnotvalue{\??ll#2\c!position}\v!yes
        {\doifvalue{\??ll#2\c!repeat}\v!yes\!!donecfalse
         \doifvalue{\??ll#2\c!state}\v!repeat\!!donecfalse}%

while in MkIV it's

    \ifx\@@currentlayerposition\v!yes
      \edef\@@currentlayerrepeat{\csname\??ll\currentlayer\c!repeat\endcsname}%
    % \edef\@@currentlayerstate {\csname\??ll\currentlayer\c!state\endcsname}% actually this is already set
      \ifx\@@currentlayerrepeat\v!yes
        \!!donecfalse
      \else\ifx\@@currentlayerstate\v!repeat
        \!!donecfalse
      \fi\fi
    \fi

MkII expects position ≠ yes while MkIV continues only when position = yes
what's wrong, you can add \unless before the \ifx and the layer mechanism works.

    \unless\ifx\@@currentlayerposition\v!yes
      \edef\@@currentlayerrepeat{\csname\??ll\currentlayer\c!repeat\endcsname}%
    % \edef\@@currentlayerstate {\csname\??ll\currentlayer\c!state\endcsname}% actually this is already set
      \ifx\@@currentlayerrepeat\v!yes
        \!!donecfalse
      \else\ifx\@@currentlayerstate\v!repeat
        \!!donecfalse
      \fi\fi
    \fi
  \fi
