Updated Nougat Porting Guide For MTK 6592 KK Kernel (3.4.67)

 Many MTK6592 users asking me for perfect Nougat porting guide  so here's the guide for Nougat . 

Simply follow it and port Nougat ROMs for your device. It's the tested guide.

So let's start :-

=============================================================

First extract your Port rom then follow below instruction : 

 ==============================================================

<<<< In META-INF Folder >>>>

Go inside folder then go to com>google>android>updater-script and then edit mount points of "system" and "data". Mount points like this "mmcblk0p6" this is my device mount point of "system" and "mmcblk0p8" this is mount point of "data" you have to replace these mount points with your device mount points (install disk info app and yo can see the mount points of your device there).

===============================================================

<<<< In system folder >>>>
Go inside system folder then go to etc folder
Then copy and replace these files from your STOCK ROM to PORT ROM :

bluetooth (whole folder)

firmware (whole folder)

wifi (whole folder)
spn-conf

apns-conf

In  lib folder :-
Go inside lib folder
Then copy and replace these files from your STOCK ROM to PORT ROM :

libaudio.primary.default

libcam.camadapter

libcam.exif

libcam.paramsmgr

libcamalgo

libcamdrv

libcameracustom

libdpframework

libfeatureio

libimageio

libimageio_plat_drv

libMali

Inside hw folder :-
hwcomposer.mt6592

===============================================================

 In Boot img :-
Replace from STOCK ROM to PORT ROM :

zImage

Camlines(in init.6592.rc in Camera Section)

===============================================================

Now repack your extracted zip and flash it via custom recovery (TWRP suggested)

And Enjoy new Roms for your device 

Happy porting !!!

=============================================================

Bugs Fixing :

1. If you face no sound issue then flash this patch NoSoundFix

(if still no sound then replace "libaudio.primary.default" from stock rom)

2. If you face scratches like screen then replace "gralloc.mt6592" from your stock rom.
