[TUT] How to port mt6572 (ubifs) to mt6572 chipset

Hi guys, Sorry it's been a long time to make a tutorial on how to port Rom. Since a lot of member in rio fun fb group want to learn how to port ubifs. Almost 4 months that I don't have a device and since I'm busy now I'm no longer  to make a new Rom for you. This method will help you to port by yourself. I just want you to learn how to port mt6572 ubifs chipset from ROM of mt6572. This porting method was tested in MyPhone Rio Fun mt6572 ubifs running in jellybean only.


Requirements :

* Windows XP/7/8
* phone mt6572 ubifs
* 7-Zip
* Notepad++
* Stock ROM
* Port Rom

Golden Rule: Backup First

Note: : There are two type roms
    1. Stock rom [ orginal rom from your mobile ]
    2. Port rom [ Any rom want to port ]

 Procedure:
    *SO NOW PORTING START
# TIPS FOR SYSTEM FOLDER

 Step 1:  Replace it from your stock rom to the port rom
[ FOLDER & FILE TO REPLACE ]

-System/bin/ipod
-sytem/bin/vold
-system/lib/hw
-system/lib/modules
-system/etc/firmware
-system/etc/vold.fstab
-system/etc/vold.fstab.fat.nand
-system/etc/vold.fstab.nand
-boot.img
-META.INF




Step 2: Now open the Port Rom folder go to META-INF/google/Android / and open updater-script in Notepad++
And change these line.......

format("ext4", "EMMC", "/dev/block/mmcblk0p4");
mount("ext4", "EMMC", "/dev/block/mmcblk0p4", "/system");

into

mount("ubifs", "MTD", "system", "/system");
mount("ubifs", "MTD", "userdata", "/data");

.Step 3:  Edit updater script via notepad++  check this
symlink("/system/lib/modules/wlan_mt6582.ko", "/system/lib/modules/wlan.ko");

Step 4: Replace the stock boot.img to port rom

Then Check or copy this code below in updater-script

assert(package_extract_file("boot.img", "/tmp/boot.img"),

      write_raw_image("/tmp/boot.img", "boot"),

      delete("/tmp/boot.img"));

Step 5:  Now go to back the folder of port rom and you will see two folder and one file name
+ META-INF
+ system
+ boot.img

Step 6:
* Now select these 2 folder 1 file and click right mouse button and click on 7zip ->> add to archive
* Now a dialogue box should
appear!
* Configure the Format like This:
Archive format: ZIP
Compression Level : Normal
Compression Method: Deflate
