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 ofBase 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 openinit.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 BaseROM'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/etcfolder 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 ro.config.alarm_alert=GoodMorning.ogg ro.config.sms_received_sound=FadeIn.ogg ro.config.sms_delivered_sound=MessageComplete.ogg
FOR ParanoidAndroid And PAC: Quote: Quote:Copy paranoid folder inside system/etc to yours.. Go to META-INF/com/google/android/Updater-Script of your base ROM and open it with Notepad++ Copy this line:
Code: set_perm(1000, 1000, 0644, "/system/etc/paranoid/properties.conf"); Quote:Specially For PA:
Quote:Now Open Build.prop in /system with Notepad++ Copy these lines in Additional Properties of Build.prop:
Code: #Depends on Resolution Of your device can be pa_hdpi/pa_mdpi/pa_xhdpi. Change it according to your device. ro.pa.family=pa_mdpi #Depend on pa version. Replace x.xx with the version of PA you are porting. ro.pa.version=x.xx Quote:Specially For PAC Rom:
Quote:Now Open Build.prop in /system with Notepad++ Copy these lines in Additional Properties of Build.prop:
Code: #Replace the x.x.x with your PAC Rom version ro.pac.version=x.x.x #Customize these lines according to your wish. ro.pacrom.version=mesona_PAC_jb-alpha-v19.0.0 ro.modversion=mesona_PAC_jb-alpha-v19.0.0 #Depends on Resolution Of your device can be pa_hdpi/pa_mdpi/pa_xhdpi. Change it according to your device. ro.pa.family=pa_mdpi #Depend on pa version. Replace x.xx with the version of PA you are porting. ro.pa.version=x.xx #Modify this line according to your AOKP version ro.aokp.version=mesona_jb-Milestone-1 #Modify it according to your base ROM's build.prop ro.cm.version=xxxxxxxxxxxx Replace any line in Your build.prop which appear twice mainly ro.cm.version and ro.modversion Quote:For HTC Devices:

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 computerBe sure to have USB debugging enabledNow 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
