To change the icon of NavigationDrawer backbutton, you need to call following method, with your image resourceid:

mDrawerToggle.setHomeAsUpIndicator(resId);

and setDrawerIndicatorEnabled() method should not be set to false to update the icon:

mDrawerToggle.setDrawerIndicatorEnabled(false);

because is setDrawerIndicatorEnabled(), is set to false it will do two things:

disables the HomeAsUpIndicator icon
disables the clickListener.

Also you can try it with actionbar:

The below function is added in android API level 18 and upper.

ActionBar().setHomeAsUpIndicator(R.drawable.ic_yourindicator);

If you use support library, try this:

getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_yourindicator);

Also you can try it with Styles:

The "up" affordance indicator is provided by a drawable specified in the homeAsUpIndicator attribute of the theme. To override it with your own custom version it would be something like this:

<style name="Theme.MyFancyTheme" parent="android:Theme.Holo">
    <item name="android:homeAsUpIndicator">@drawable/my_fancy_up_indicator</item>
</style>

If you are supporting pre-3.0 with your application be sure you put this version of the custom theme in values-v11 or similar.

if it's still not working, you can try by replacing:

<item name="android:homeAsUpIndicator">@drawable/my_fancy_up_indicator</item>

with:

<item name="homeAsUpIndicator">@drawable/my_fancy_up_indicator</item>

Add this to your option menu selected listener.

@Override

public boolean onOptionsItemSelected(MenuItem item) {
    Intent intent;
    switch (item.getItemId()) {

        case android.R.id.home:
            onBackPressed();
            break;

    }
    return true;
}
