Porting Process

All the Things you have to do at your won Risk. I will not be responsible for any kind of Brick/Damage of your phone.

Step  –  1

First of Download both “Stock ROM” and which “Portable ROM”. Usually you find Stock ROM on your handset manufacturer official forum. Stock ROM and Portable ROM both ROM can be found in .ZIP format. First Unzip them both, than Create a New Folder anywhere in you computer and rename it

• System

Inside the system folder create 2 “New Folders” and rename them as

• etc
  
• lib

Step –  2

Now You have to copy some files from your Stock ROM to newly created System folder. Open your Stock ROM folder and System folder.

• Folder
  • firmware 
    
  • permission 
    
  • security 
    
  • wide-dhcpv6
• Files
  • vold.fstab
  • vold.fstab.nand

Copy From Stock ROM “lib” folder to “System\lib” folder

• Folder
  • hw
  • drm
  • modules
  • soundfx
• Files
  • libaudio.primary.default.so
  • libcamalgo.so
  • libmhaldrv.so
  • libcamera_client.so
  • libcameracustom.so
  • libcameraprofile.so
  • libcameraservice.so

Now copy full “usr” and “vendor” folder from Stock Rom to System folder.

Step – 3

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.
