[GUIDE]How To Port Different ROMS to Your Device (Simplest and Fastest)

Many people have requested me to share the method which I am using to port roms..

THIS IS THE SIMPLEST AND FASTEST WAY TO PORT ROMS!!!

This is the method which I use in porting Roms-
Things Needed- Winrar, Notepad++

You can use this Method to port roms From armv6 to armv7 devices but I dont know about the method used to port roms from armv7 to armv6 devices..

Quote:

What is base Rom:

Quote:

The ROM which is Developed For your Mobile..

Quote:

What is Port Rom:

Quote:

The Rom Which you want to port to your Device.

Quote:

STEP1;

Quote:

Take any clean CM9, AOSP, CM7, CM10, CM11 ROM which is running on your device as Base ROM.

Quote:

STEP2:

Quote:

Extract it Using Winrar.

Quote:

STEP3:

Quote:

Take the ROM you want to port. This Port ROM. Extract it also using Winrar.

Quote:

STEP4:

Quote:

Delete app, Framework, Fonts and Media folder in System Folder of Base ROM.

Note: To Port Kitkat base ROM, you also have to copy the priv-app folder from port to base. Thats It.. (Credits to @thelegend10 for informing me that this guide works with KK)

Quote:

STEP5:

Quote:

Now copy app, Framework, Fonts and Media folder in System Folder from Port rom to base rom system folder.

Quote:

STEP6:

Quote:

Now open etc folder in both the ROMs folder.

Quote:

STEP7:

Quote:

In etc folder of base ROM open permissions folder and copy all the permissions files in Port rom to your base ROM folder except platform and handheld_hardware .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.

Quote:

STEP8:

Quote:

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

Quote:

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

Quote:

STEP9:

Quote:

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

Quote:

ro.config.ringtone=
ro.config.notification_sound=
ro.config.alarm_alert=

Also Copy anything you Find Extra in ADDITIONAL BUILD PROPERTIES related to theme..

Quote:

STEP10:

Quote:

COPY THE set_perm Lines in META-INF/com/google/android/updater-script From Port to Base ROM After Deleting set_perm lines in Base ROM's Updater-Script.

Quote:

STEP11:

Quote:

If You find any extra file or folder in system folder of PORT rom than copy them to your base rom system folder.

Quote:

STEP12:

Quote:

Last Step to ZIP THE FOLDERS IN ONE..
SELECT META-INF, system, boot.img(if it is having), data(if it is having).
Right Click and Select Add to Archive..
Select Zip..
Type the Name.
Click OK..

FOR MIUI:

Quote:

Quote:

Copy telocation.db and yellowpage.db From /system/etc folder to yours..

Copy content-types.properties file From /system/lib to yours..

Copy invoke-as from miui4 rom to /system/xbin and give it permissions on updater-script
set_perm(0, 0, 06755, "/system/xbin/invoke-as");
Note:It is needed for backup & themes app to work

Quote:

Copy liblbesec.so from miui 4 to /system/lib and give permission on updater-script
set_perm(0, 0, 0755, "/system/lib/liblbesec.so");
It is needed for superuser app from miui to work

Quote:

Change values Some of the Values in build.prop of your ROM:
ro.build.id=MIUI
ro.build.display.id=MIUI
ro.build.version.incremental=2.x.x (version number)

ro.config.ringtone=MI.ogg
ro.config.notification_sound=FadeIn.ogg

How to logcat?

I know that many of you are having problems while porting and I know that those problems cannot be solved simply by guesswork..
There is a solution to find the problems which are causing BOOTLOOPS OR OTHER PROBLEMS IN YOUR PORT ROM..
The SOLUTION IS TO TAKE A LOGCAT..

Quote:

LOGCAT ARE OF TWO TYPES:

Quote:

• In your Phone(if the ROM is booting)
• Through adb(if you are stuck in bootloop)

Quote:

In your Phone:

Quote:

There are two ways to take LOGCAT in mobile:

Quote:

FIRST WAY--THROUGH APPS WHICH ARE MADE TO TAKE LOGCAT:

Quote:

There are two apps which you can use to take a LOGCAT..
They are aLogcat or Catlog.
Taking logcat through apps is very easy.

Quote:

SECOND WAY--THROUGH TERMINAL EMULATOR

Quote:

SEE THE INSTRUCTIONS BELOW TO TAKE A LOGCAT THROUGH adb

Quote:

HOW TO MAKE PC READY FOR LOGCAT?

Quote:

IN WINDOWS:
Download Android SDK From Here
Install or Extract it to your desired Directory..
You also need to install Java JDK.
Download it here
In the Guide, we are taking C: as the Root Directory and android as the main Folder

• Navigate to Android SDK folder and open 'SDK Manager.exe'
• Only check 'Android SDK Tools' and 'Android SDK Platform-tools'
• First connect the device via USB to your computer
• Be sure to have USB debugging enabled
• Now Navigate to C:/Android/android-sdk/platform-tools/
• Now Open a Command Prompt there By holding Shift+Right Click Button

Quote:

IN LINUX:
IMPORTANT: If someone has a 64bit linux then they need to download 32-bit libs
for this, before all these steps run this:

Code:

sudo apt-get install ia32-libs

Make sure that you have Android-SDK and JDK downloaded on your PC
If you have not installed them, Android SDK from here and Java JDK in this way:

Code:

sudo add-apt-repository ppa:ferramroberto/java
sudo apt-get update
sudo apt-get install sun-java6-jdk sun-java6-jre sun-java6-plugin

OR

$ sudo add-apt-repository ppa:sun-java-community-team/sun-java6
$ sudo apt-get update
$ sudo apt-get install sun-java6-jre sun-java6-bin sun-java6-jdk

OR You Can Simply Do This: (Credits to @Androguide.fr)

This process saves a lot of storage. It uses the Ubuntu Touch ppa:

Code:

sudo add-apt-repository ppa:phablet-team/tools
sudo apt-get install android-tools-adb

You can also install fastboot in the same fashion:

Code:

sudo apt-get install android-tools-fastboot

Then follow the Below Instructions Carefully:

Make a new directory by this command in terminal:

Code:

mkdir android

Then extract the downloaded SDK by

Code:

tar -zxvf ~/Downloads/android-sdk_r21.0.1-linux.tgz

Then move it to the directory we just made

Code:

mv android-sdk-linux ~/android/sdk

Then open android sdk manager by

Code:

android/sdk/tools/android

This will open Android sdk manager. Just select android sdk tools and android sdk platform tools for adb and then select install packages

Go into your Home folder and Press CTRL+H (This is done to show hidden folders and files)
Look for the file '.bashrc'
Open it and put the following or similar:

Code:

export PATH=$PATH:~/android/sdk
export PATH=$PATH:~/android/sdk/platform-tools
export PATH=$PATH:~/android/sdk/tools

You will need to add something for any devices to be recognized:
Open terminal(Ctrl+alt+T) and enter:

Code:

sudo gedit /etc/udev/rules.d/51-android.rules

Enter the following in the file:

Code:

SUBSYSTEM=="usb", ATTR{idVendor}=="0502", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="413c", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="0489", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="091E", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="12d1", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="0482", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="1004", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="0955", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="10A9", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="04dd", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="0fce", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="19D2", MODE="0666"

Now save and close the file, and in terminal enter:

Code:

sudo chmod +x /etc/udev/rules.d/51-android.rules

Now Type:

Code:

sudo gedit /etc/rc.local

This will open a file
now add the line mentioned below just above where it is written exit 0

Code:

/home/user/android/sdk/platform-tools/adb start-server

"Enter your username in place of user"
After this we don't need to cd to adb directory..We just have to type adb devices and the phone will surely show up.

Now that everything is installed
Open terminal and type:

Code:

android

OR, if that doesn't work

Code:

cd ~/android/sdk/tools
./android

Quote:

HOW TO TAKE LOGCAT?

Quote:

To verify that the device is connected Type:

Code:

adb devices

Now type:

Code:

adb logcat > logcat.txt

The LOGCAT will be Saved in the logcat.txt File
You can also type:

Code:

adb logcat -f logcat.txt

Or

Code:

adb logcat -v long > logcat.txt

With the -v flag & the long argument, it changes output to long style, which means every line of logcat will be on its own line (makes it a little neater, imo)
Note: When outputting to a file, you will see a newline, but nothing printed, this is normal. To stop logcat from writting to a file, you need to press ctrl+c.

Quote:

Meanings of symbols in a logcat !

Quote:

You usually see this at the start of a sentence in logcat .
I/> ===> Information
S/> ===> Silent
D/> ===> Debug
W/> ===> Warning
E/> ===> Error
F/> ===> Fatal

Build.prop and Updater-Script Terminology and Guide to Edit it

Quote:

Standard build.prop properties

Please read the hashed out lines : It is selfexplanatory.

So the normal build properties start with:

Code:

# begin build properties
# autogenerated by buildinfo.sh

Quote:

This mentions that the build prop is built by build info shell script during the compilation of the ROM.

Code:

#First up the build id (Here JZO54K) is the build id for the version number for Jellybean 4.1.2
ro.build.id=JZO54K
#It is the version of the ROM which appears in the about phone. This is a cm10 build by sakindia123.
ro.build.display.id=cm_pico-userdebug 4.1.2 JZO54K eng.sakindia123.20121117.161006 test-keys
#This is the software development kit version which is needed and used for building the ROM.
