• A Custom Recovery: If you don’t have follow this tutorial to port one!
• Custom ROM (from a device with almost same specifications and SoC) [i hope you have read the guides mentioned before, if not go and read them].
• Your Stock ROM Zip.
• Now you need 2 android applications, One which can handle .zip archive and one that can edit .txt files. There are plenty of apps available on play store that can do mentioned tasks so do search on play store. Or you can Use FX File Manager  or  ES File Explorer these both file managers can do both tasks (Open .zip files and edit .txt files). Choice is yours.

What you need to Port Custom ROM to your device [Your Chipset to Your Chipset only]:

• The ROM you need to port [in .zip]. [Port Rom]
• Your stock ROM [extracted with /system and build.prop]. [Base/stock Rom]

1. Extract the ROM you need to port and you will have these main things:

1. META-INF
2. System
3. boot.img.

• If you have them then you are ready for next step.

2.  Extract both stock and port roms zip with any zip archiver application and then replace files mentioned below respectively :-

For Porting CyanogenMod 12.1 Lollipop

Just find the files and replace :[From Stock To Port]

• a. hwcomposer.mt65xx.so  <--- File
• b. libmali.so  <--- File
• c. -system/etc/firmware   <-- Folder
• d. -system/lib/modules*  <--- Folder
• e. -system/usr/keylayout/Generic.kl   <--- File
• f. Open system/lib/hw folder in Stock ROM folder, then select & copy all files and paste to inside the system/lib/hw folder in Port ROM and replace files don’t delete.
• g. In boot.img: (read guide to know how to port boot.img on mobile)
  - kernel/zimage
  - ueventd.rc

Note: - if you porting a ROM from a different SOC [6582 to 6592], delete these files before in port rom, like this:

• ·         audio.primary.mt65xx.so,
• ·         audio_policy.mt65xx.so,
• ·         gralloc.mt65xx.so,
• ·         hwcomposer.mt65xx.so,
• ·         ligths.mt65xx.so,
• ·         sensors.mt65xx.so etc.

After doing this go to step 3. 

For Porting CyanogenMod 13 Marshmallow

Just find the files and replace :[From Stock To Port]

a. In system/lib/:

• - libMali.so
• - hwcomposer.mt6582.so
• - libaudio.primary.default.so
• - libcameracustom.so
• - libcamalgo.so
• - libcamdrv.so

3. Finally At the end:

Open the updater-script in META-INF from port rom, open it with any text editor application and. Edit the format & mount points(compare with your updater-script from stock META-INF)

format("ext4", "EMMC", "/dev/block/mmcblk0p7", "0", "/system");

format("ext4", "EMMC", "/dev/block/mmcblk0p5", "0", "/data");

mount("ext4", "EMMC", "/dev/block/mmcblk0p7", "/system");

• The final step! Press back button to go to the main folder where you have the Stock ROM. Copy boot.img [From Stock ROM]and replace it with the Port rom‘s boot.img.
• Then go to port roms parent directory and select both folders and your ported boot.img and archive/compress them in a zip file.
