[GUIDE][MOD][4.0.4] Add Hide time and am/pm toggle topic

***Here is a guide for Adding Hide time and am/pm toggle in Samsung ICS Devices***

This guide is specially for GT-S7562. But should work for other Samsung ICS devices also. Values may differ.

Quote:

Things you need: Tool for decompiling/compiling work (I will not cover this, there are many guides for this) Notepad++ Patience Some common sense :D

Here, we will edit two files:

• SecSettings.apk


• SystemUI.apk

Here we start-

Decompile SecSettings.apk

Open smali/com/android/settings/DateTimeSettings.smali

Add blue one
