Just few days ago there was a breakthrough for users of MediaTek devices as an XDA user Aditya Kr who successfully ported Android Nougat Custom on his MTK device.
Other users of MediaTek devices started to port for various devices and successfully booted it also. This guide will help you to Port Lineage OS Nougat Custom Rom on mediatek device.

Follow the below guide carefully and in no time you'll also enjoy Nougat on your Android device.

This porting method has been known to work on these chip sets: 
Mediatek MT6582 chip set running on KitKat kernel
Mediatek MT6592 chip set running on KitKat kernel

FILES NEEDED:
.Boot Image Unpack Tool.
Read:
.File explorer
.Stock ROM
.Custom/Port ROM you want to port from

  • First create two folders called Stock and Port
  • Place Stock ROM in stock folder
  • Place Custom ROM in port folder
  • Use 7zip to unzip both ROMs in respective folders
  • Port boot image with THIS or THIS method
  • Copy boot.img to Custom ROM folder you extracted and replace boot.img there
FOR MT6572 CHIP SETS:
Use boot image from any device (same chip set) with a working lineage OS ROM

Now copy these files from stock to port:
  • System/lib/hw/hwcomposer.mt65**.so
  • System/lib/libaudio.primary.default.so
  • System/lib/libcameracustom.so
  • System/lib/libcamalgo.so
  • System/lib/libcamdrv.so
  • System/lib/libfeatureio.so
  • System/etc/firmware
  • boot/kernel
  • boot/unventd.rc (only if you are getting stuck at logo)
  • boot/Replace only camera lines under #Camera from stock boot.img init.rc to init.mt6572.rc

    From System/lib/hw: Delete all mt6572.so blobs and replace with these blobs: DOWNLOAD BLOBS 

    Now copy these files from stock to port:
    • System/lib/hwcomposer.mt65xx.so
