Porting From Different SoCs ( Ex: MT6582 to MT7572 )

By
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

ro.mediatek.platform=MT65xx

Now Replace this (MT65xx) with your CPU!!

For Example

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"

set_perm(0, 0, 0644, "/system/vendor/lib/hw/gralloc.mt65xx.so");

[Replace the mt65xx with your cpu]

Example:

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 files from PORT-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
#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 :

#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!!!!

Porting Lewa OS5 ROM:

* Replace These files from Stock to LeWa OS5 ROM

* Replace Stock boot.img to Lewa OS5 ROM

* Unpack boot.img

* Open init.rc

* Find these lines
