How to get the build.prop values?

Question

How do I get the build.prop values that are found in /system/build.prop without root access? How do I edit them?

Answer 1

On the setting page of your file manager, set home as /system, then you could browse system folders and copy build.prop and paste to sdcard. I'm still trying to root my phone but I have no problem tweaking on the way (no pun).

Answer 2

To read properties using reflection on the hidden API :

static public String getprop(String key){
    try { Class c = Class.forName("android.os.SystemProperties");
        try { Method method = c.getDeclaredMethod("get", String.class);
            try { return (String) method.invoke(null, key);
            }  catch (IllegalAccessException e) {e.printStackTrace();}
            catch (InvocationTargetException e) {e.printStackTrace();}
        } catch (NoSuchMethodException e) {e.printStackTrace();}
    } catch (ClassNotFoundException e) {e.printStackTrace();}
    return null;
}

To edit them (Root required) manually, you should extract them with adb :

adb pull /system/build.prop

Edit them on the computer, then "install" the new build.prop :

adb push build.prop /sdcard/
adb shell
    mount -o rw,remount -t rootfs /system
    cp /sdcard/build.prop /system/
    chmod 644 /system/build.prop

Would be safer to keep an original build.prop copy.
