Please elaborate for bootloop.
as you said replace these files from port system folder & repack your boot image.
what changes it will make to boot image ?
will this work for 32 bit or 64 bit ?

Always when i had that problem, i had to go to system/etc/dhcpcd and change the permission of dhcpcd-run-hooks so that "Owner", "Group" and "Others" can execute. Also in build.prop you can change ro.secure.storage=true to false (if it's not already). This is usaly for not saving the password but worth a try.
And by the way if someone has more knowledgement than me:
I'm on the Note Edge and therefor does no exist a CM 13 version. I have read somewhere you can do it also with a sammy rom as base. So i took a S7 edge rom and a Note edge rom, both 6.0.1. I get it to flash and boot but endless boot. I pulled the prev_dump.log to get the errors but all i can see is this

But i don't know how to solve it.
Or is it kernel related because of selinux (i use stock Note edge)?
Code:
