[GUIDE] [PORT] [ROM] All About Mediatek ROM Porting

HOW to Port ROMs...

For Begineers & Advanced Users

Almost Any Device to Any Device!


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!!

* Camrea:

Code:

\system\lib\libcamalgo.so
\system\lib\libmhaldrv.so
\system\lib\libcamera_client.so
\system\lib\libcameracustom.so
\system\lib\libcameraprofile.so
\system\lib\libcameraservice.so

* GPS:

Code:

(NOT NEEDED IN MT6572)

Code:

fmradio.driver.chip=1

(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)

Code:

mediatek.wlan.module.postfix=_mt6620

(Replace mediatek.wlan.module.postfix=_mt6620 to your WLAM Chip Type Ex: mediatek.wlan.module.postfix=_mt6628 for MT6628)

* Now open updater-script and Find this line or ADD a New one(If Not Found)!!

symlink("wlan_mt6620.ko", "/system/lib/modules/wlan.ko")

(Replace wlan_mt6620.ko to your WLAM Chip Type Ex: wlan_mt6628.ko for MT6628)




It Took Me 2Days & 5 Hours to Collect Data & Write this Thing!
I didn't Eat or Drink Water Properly,I Didn't Sleep Properly,
I Created This just for you all!
So That No ONE Ever Says Modontek Again! Its Against Humanity!
Please Value my Work & Do Not Blame me if it Doesnt Work!
I Work Day & Night to Learn More & More!
I Respect All the Developers & Modders of Android
But Some Jerks Just Dont know How to Behave like a Human!
Some Developers Behave like they are the BEST! LOL!
But It's NOT TRUE!
We Can't Be the Best! We Are All the Same!
We all are the Students of XDA-University!
We all use Others Work!
Why Not Work together? Why Not Develop our Knowledge More & More!??
I Don't think I Own any Respect from anyone!
But I Think I Own Respect for my Works & Contributions to Andoid Open Source Project!
I Believe in Humanity! Please Do NOT Copy This and Take Credits!
If This Was Helpful to you in Any Way...
Just Mention my Name in your ROM and Give me Some Credits!
