TUTORIAL PORTING ROM

Ok.. so first thing first…

1. Any Rom can be ported from any device having mt6589 cpu to iBall Andi 4.5h
2. “Base rom” is any full functional rom of andi 4.5h and “port rom” is the rom u want to port.
3. Tools u need are Master Shifu dsixda's Android Kitchen, Apk tool, 7zip tool, notepad
++, photo shop (optional).
4. You should be rooted and custom recovery should be installed.



Now download the rom u want to port (I am saying again… it should be of mt6589 cpu based rom) ….

What actually we are doing here is porting all those features of base rom to port rom which will not work by keeping port’s main features as they are… so that it will feel u are using complete port rom…

I use two phases of porting… one is using kitchen and other part is manual…

Kitchen part::

Use dsixda’s Android kitchen to port base’s kernel to port’s kernel… search for kitchen tutorial in other forums of XDA (how to configure and install kitchen using cygwin)… I assume u use windows xp, 7 or 8…

The procedure is,

• Use kitchen to unzip your port rom… u can add root, add busybox, deodex ur rom, add init.d, add /data/app feature at this stage depending upon the status of your port rom….
• Now use kitchen to decompile boot.img of port rom and also base rom…
• Replace base zImage (kernel) to port’s boot_extracted folder..
• Combine base’s zImage and port’s ramdisk and recompile to create new boot.img
• Now build rom from working folder, zipalign apk’s, sign zip file
• At the end u will find a new zip file in OUTPUT_ZIP folder of kitchen
• Now check updater-script of new zip and compare with old zip file… change things accordingly…
• Remember for our phone system partition is /dev/block/mmcblk0p3
• Data partition is /dev/block/mmcblk0p5
• U need these information frequently

Ok… so kitchen part is done….

Manual Part::

Now open the new port rom zip file using 7zip file explorer… and also open ur base rom zip file using 7zip file explorer…. Keep both explorer window side-by-side… so that u can see contents of both zip in one view… do these…


1. Go to /system/etc/firmware in both the roms… drag and drop below files from base to port

7. Go to /system/usr in both the roms… drag and drop below files from base to port

Whole ‘srec’ folder

8. Go to /system/xbin in both the roms… drag and drop below files from base to port

9. Open /system/build.prop file of port rom using notepad++ and put the same values as base rom for

ro.build.display.id=
ro.product.model=
ro.product.brand=
ro.product.locale.language=
ro.product.locale.region=
fmradio.driver.chip=
mediatek.wlan.chip=
mediatek.wlan.module.postfix=

10. Open /META-INF/com/google/android/updater-script of port rom using notepad++ and put the same values as base rom for

symlink("/system/lib/modules/wlan_mt662x.ko", "/system/lib/modules/wlan.ko");

11. Go to /system/app in both the roms… drag and drop below files from base to port

13. Save files and put them to their proper place in port zip file
14. Now the basic porting is over…. any apk file of port rom can be modified using apktool by decompiling it, modding it and recompiling it… search for apktool tutorial in other forums of XDA…
15. Any background images can also be changed using photoshop and placed back to proper location of apk using decompiling and compiling by apktool….

THIS TUTORIAL I MADE FOR ANDI 4.5H IBALL PHONE… HOWEVER IT CAN BE USED FOR ANY PHONE WITH MT65xx CPU WITH MINOR CHANGES….

DON’T POST ANY ROM UNTIL YOU CHECKED IT ON YOUR DEVICE COMPLETELY…!!!
