How to make some modding to TouchWiz 3 on androiid phones!

This is a guide on on how to make some modding to TouchWiz 3.
[Important] it is recommended to have a second launcher installed as a backup before you start.
Make a full backup of your phone in case something goes wrong. you never know.

The guide is set in 3 parts:

Part I: Copying the TouchWiz apk file to your computer and decoding it.
Part II: Editing Files. Here are included different modifications. you can chose the ones you want to apply and skip the rest and go to part III.
Part III: updating your apk file and copying it to your phone.

You will need:

• Apktool to decompile/build your apk files. (download it and install it)
• ADB (download it and install it) I use Android Commander but adb commands make the guide simpler :P )
• winrar or 7zip or any archive manager
• Notepad++ or any text editor

Part I: pulling & decoding

1. Create a folder in your computer to work inside it. for example C:\twmod
2. Connect your phone with USB Cable.
3. Copy the TouchWIz apk file from your phone to C:\twmod on your computer. you will find it under /system/app
   to do this i recommend using Android Commander because it's easy to use. you can also use Root Explorer or ADB. i will include the ADB commands in this guide.
   [if you're using ADB] open a command prompt and enter the following commands:

   adb pull /system/app/TouchWiz30Launcher.apk c:\twmod\TouchWiz30Launcher.apk

4. Decode the file using apktool. In the command prompt enter the following commands:

   cd c:\twmod
   apktool d TouchWiz30Launcher.apk

   a folder will appear next to your apk file named TouchWiz30Launcher
   (leave this command prompt open)
