[GUIDE]PORTING MEDIATEK DEVICES

Guide in Porting Mediatek Devices

WORKS FOR:

Only for ICS To ICS & JB To JB(also works with 4.1 to 4.2)
~~MT6589 To MT6577~~
~~MT6582 To MT6572~~
~~MT6577 To MT6575~~

Requirements:
 - PC(Windows XP/7/8)
 - 7-zip
 - Notepad++
 - Bootimg Unpack/Repack Tools for Windows
 - Brain
 - Patience
 - Coffee?

Now?

Porting for the same SoCs(Like MT6572 To MT6572)

~Replace these from your STOCK to the ROM(Call it Port) u want to port!

Files For Replacing

 *system/vendor

 *system/usr

modules
 *system/lib

 *system/lib

//hw

 *system/lib/libncurses.so

tc/vold.fstab
 *syste

 *system/etc/firmware

 *system/

em/etc/vold.fstab.nand



 *system/etc/bluetooth

For Fixing Problems

 *system/etc/permissions

 *system/etc/security

ystem/etc/wifi
 *s

 *system/etc/audio

 *

system/lib/drm

em/lib/soundfx

 *system/lisys

t

* 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!!!

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

 mount("ext4", "EMMC", "/dev/block/mmcblk0p5", "/system");

This is the Stock one!!

 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:

 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--

 *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:

/system/xbin/libmnlp

* Bluetooth & Wifi:

Code:

/system/lib/libbluetooth_mtk.so
/system/lib/libbluetoothem_mtk.so

* Radio:

Code:

\system\lib\libaudio.a2dp.default.so
\system\lib\libaudio.primary.default.so
\system\lib\libaudiocompensationfilter.so
\system\lib\libaudiocustparam.so
\system\lib\libaudioeffect_jni.so
\system\lib\libaudioflinger.so
\system\lib\libaudiosetting.so
\system\lib\libfmar1000.so

\system\lib\libfmmt6616.so
\system\lib\libfmmt6620.so
\system\lib\libfmmt6626.so
\system\lib\libfmmt6628.so

* For Fixing Wifi & FM-Radio do this!

(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)
