So with no more blahh blahh blahh Lets start the PORTING procedure  

What you'll need:

What is base Rom:

The ROM which is Developed For your Mobile..
You can use either CM or any other AOSP roms as your Base ROM

What is Port Rom:

The Rom Which you want to port to your Device.
Make sure that the rom has most of the hardware specifications as of your base rom

STEP 8: .And Then open init.d Folder in Base ROM and Delete Every thing except banner and then copy all the files inside init.d folder of port ROM to Base ROM.

STEP9:

Now open buid.prop file using Notepad++ and make changes to these of Base Rom as you wish.

ro.build.id=
ro.build.display.id=
ro.build.date=
ro.modversion=

STEP10:

In build.prop file change these to same as Port Rom build.prop values.
