Step 3. Porting
Go to the Port Rom folder.
You need to delete some 3 folders from Port Rom system folder are below:


system\etc\firmware
system\lib\hw
system\lib\modules


Now paste system folder (Created with Stock Rom files) and replace files and folders to the port rom system folder (Not inside the port rom system folder)

File copied completed. 

Now you have to edit Mount Point 

Go to Port Rom META-INF\com\google\android open updater-script with Notepad++ change the mount point.

Find the line /dev/block/mmcblk0p and you will get the line like below. 

format("ext4", "EMMC", "/dev/block/mmcblk0p5", "0", "/system");
mount("ext4", "EMMC", "/dev/block/mmcblk0p5", "/system");
mount("ext4", "EMMC", "/dev/block/mmcblk0p7", "/data");

Mount point I marked in red color 5 & 7 now change it as per your device mount point. (Do not need to change the whole line.) If your device mount point for system is 3 then make it 3 instead of 5. If your device mount point for data is 5 then make it 5 instead of 7. To know your device mount point run MTK Droid Root and Tools and connect your device. Then click Block Map.
