Tutorial:
ONLY FOR MEDIATEK SoCs
In This Guide You'll Learn..
How to Port ROMs of the Same CPU
And Also..
HOW TO PORT ROM FROM A DIFFERENT SoC 
Works for-
MT6589 to MT6577
MT6582 to MT6572
MT6577 to MT6575
Only ICS to ICS & JB to JB
May also work with 4.1 to 4.2
No Need of Source Code
No Need of Kernel Source
No Need of **ANDROID KITCHEN
No Need of LINUX... 
Requirements:
* A Brain
* Patience
* Windows XP/7/8
* 7-Zip
* Notepad++
* Bootimg Unpack/Repack Tools for Windows!
* Stock ROM
* And a Little Respect!!
So now Lets Begin...
PORTING For Same SoCs ( Ex: MT6572 to MT6572)
* Replace these from your Stock ROM to the ROM u want to PORT!! Lets Call it "PORT"
FILE LIST FOR REPLACING:
Code:
*system/vendor
*system/usr
*system/lib/modules
*system/lib/hw
*system/lib/libncurses.so
*system/etc/firmware
*system/etc/vold.fstab
*system/etc/vold.fstab.nand
*system/etc/bluetooth
For Fixing Problems...
Code:
*system/etc/permissions
*system/etc/security
*system/etc/audio
*system/etc/wifi
*system/lib/drm
*system/lisystem/lib/soundfx
* Now Replace the Stock Boot.img to Port ROM!
* Now Open The Port ROM folder and go to META-INF/google/android and open updater-script in Notepad++
* Do the same for the Stock ROM
* Now In the Port ROM's Updater Script, find a line that starts with this...
format(".......
and only replace the mmcblk0p.. with the stock one!
* Do the same for this line...
mount("...
Example:
This is the PORT one!!!
Code:
format("ext4", "EMMC", "/dev/block/mmcblk0p5", "0", "/system");
mount("ext4", "EMMC", "/dev/block/mmcblk0p5", "/system");
This is the Stock one!!
Code:
format("ext4", "EMMC", "/dev/block/mmcblk0p3", "/system");
mount("ext4", "EMMC", "/dev/block/mmcblk0p3", "/system");
Now just Replace the "mmcblk0p3" from STOCK to PORT!!
It should look like this:
Code:
format("ext4", "EMMC", "/dev/block/mmcblk0p3", "0", "/system");
mount("ext4", "EMMC", "/dev/block/mmcblk0p3", "/system");
DO NOT REPLACE THE WHOLE LINE!
* Now go back to the Folder of Port ROM and You'll see 2 folders & 1 file named
-META-INF
-system
-boot.img
* Now Select these three and Click Right Mouse Button and Click on 7-Zip ->> Add to Archive
* Now a dialouge box should appear!
* Configure the Format like This:
Archive format: ZIP
Compression Level : Normal
Compression Method: Deflate
Dictoioany Size: 32k
Word Size 32
* Now Start Zipping and Push the ZIP to your Memory Card
* Go to Recovery >> Install ZIP & Wipe Data
Finished!!
Now was that so hard?? Its a Really Easy thing to d0!!
Now Come to the Hard Part!!
Porting From Different SoCs ( Ex: MT6582 to MT7572 )
Read this carefully & apply the way i say!
* Take the ROM u want to port & name it PORT!
* Take your Stock ROM & Name it Stock
* Now Replace These files from Stock to PORT--
Code:
*system/vendor
*system/usr
*system/lib/modules
*system/lib/hw
*system/lib/libncurses.so
*system/etc/firmware
*system/etc/vold.fstab
*system/etc/vold.fstab.nand
*system/etc/bluetooth
* Now Open build.prop in notepad++ & Search for this line
Code:
ro.mediatek.platform=MT65xx
Now Replace this (MT65xx) with your CPU!!
For Example
Code:
ro.mediatek.platform=MT6572
* Now Go To META-INF/google/android and open updater-script in notepad++
* Add this line between the lines of "set_perm"
Code:
set_perm(0, 0, 0644, "/system/vendor/lib/hw/gralloc.mt65xx.so");
[Replace the mt65xx with your cpu]
Example:
Code:
set_perm(0, 0, 0644, "/system/vendor/lib/hw/gralloc.mt6572.so");
* Now Go back to the Rom folder and Take the boot.img and decompile it with any bootimg-unpack tool!
* Now delete the zimage and rename boot.img-ramdisk to PORT-Ramdisk
* Now Do the Same for Stock boot.img and open the folder named
PORT-ramdisk and copy all the fil PORT-[QUOTE]ramdisk to
boot.img-ramdisk of your Stock boot.img
* Now Go to boot.img-ramdisk and open init.rc
* Now find these lines and replace with your cpu
Code:
#Create Chip Property
on early_property:ro.hardware=mt6582
setprop ro.mtk.hardware mt6589
on early_property:ro.hardware=mt6589
setprop ro.mtk.hardware mt6589
example :
Code:
#Create Chip Property
on early_property:ro.hardware=mt6582
setprop ro.mtk.hardware mt6572
on early_property:ro.hardware=mt6589
setprop ro.mtk.hardware mt6572
* Now Compile your New boot.img and Pack your New ROM and Flash!!
Cheers!!!!

Cheers!!
Enjoy your New ROM and Give Credits to me for if I Helped you!
For Advanced Users:
PORTING FIX:
Framework:
* decompile framework.jar
* Go to
Code:
\smali\com\mediatek
* Replace All Files from STOCK to this Folder
* Now go to
Code:
\smali\com\android\server
* Replace All Files from STOCK to this Folder
* Compile framework.jar and Push to Device!
* This Should FIX Bootloop, Mms.apk, Phone.apk, Settings.apk, Contacts.apk Force Close
* Fixing Other Problems:
Files related to Specific hardware:
* Replace if Not Working!!

(Change it to 3 if yours is MT6628)
Code:
mediatek.wlan.chip=MT6620
(Replace mediatek.wlan.chip=MT6620 to your WLAM Chip Type Ex: mediatek.wlan.chip=MT6628 for MT6628)
