unpack both images using carliv image kitchen

and replace all files except ramdisk folder from stock to port.

then open ramdisk folder and replace a file named ueventd.rc from stockboot.img to portboot.img.

NOW the tricky thing here...

Rename all files having other chipset name like your stockboot.img, SEE SCREENSHOT

now open  init.mt65xx.rc in with notepad++...

-find for mt6582 and replace with mt6572 as shown in SCREENSHOT

UNPACK portboot.img and copy to port rom folder...
