TUTORIAL ON HOW TO PORT ROMS OR CROSSPORT MT6735

I know that there are actually LOTS of "How to port ROMS" or 
"crossport Mediatek mt6735" in the web..
but I would like to share a certain source I found.
Requirements: 1. Root Explorer 2. The ROM you want to port to your phone (let’s called it the "Port ROM") 3. The ROM designed for your phone (let’s called it "Stock ROM") TUTORIAL From your Stock ROM, copy those files and overwriting the file in Port ROM: 1. stock boot.img 2. system/etc/firmware (whole folder) 3. system/etc/mddb (whole folder) 4. system/lib download the lib.zip below and copy this file MEGA Link
5. system/lib/hw/audio.primary.mt6753.so, camera.mt6753.so, gralloc.mt6753.so, hwcomposer.mt6753.so, memtrack.mt6753.so, sensors.mt6753.so 6. system/lib64/hw/audio.primary.mt6753.so, camera.mt6753.so, gralloc.mt6753.so, hwcomposer.mt6753.so, memtrack.mt6753.so, sensors.mt6753.so
That’s it! Your Port ROM is now ready to be zipped and installed on your device via Clockwork Mod, Philz or TWRP CREDITS: Mark Herrero To all Porters MaximumTeam #Maximum

Hi as my promised I will teach you the basic procedure on how to port mt6592 chipset. I've noticed some of you want to learn this porting or cross porting method.  But before you proceed make sure you have back up and have knowledges in flashing via SPFT because this is not an easy task it can cause bootloop, lost IMEI and sometimes hard brick of your device.

Requirements :

*Windows XP/7/8
* 7-Zip
* Notepad++
* Java Jdk

Note : There are two type of roms
     1. Stock rom [ original rom from your mobile ]
     2. Port rom [ Any Rom you want to Port]

Procedure:
 
 1. Replace it from your Stock rom to the Port rom
     [ FOLDER & FILE TO REPLACE ]

*system/etc/firmware
*system/etc/permission/platform.xml
*system/etc/permission/handheld_core_hardware.xml
*system/lib/hw
*system/lib/modules

And change these line.......
[mmcblkOp3 ----- mmcblkOp9]
Find the mountpoints of your SYSTEM and DATA via MTKDROIDTOOLS or  terminal emulator.
Using this command: adb shell cat/proc/dumchar_info
