menu_alter did not work
This is very common problem. What's your module weight? You can find the value in the table system. Try to change it to something more "heavier".

update DATABASE_NAME.system set weight = '99' WHERE name = "MODULE_NAME";


Standard approach hot to set a modude weight is to declare it in MODULE_NAME.install file:

/**
 * Implements hook_enable()
 */
function MODULE_NAME_enable() {
    db_update('system')
    -&gt;fields(array('weight' =&gt; 99))
    -&gt;condition('type', 'module')
    -&gt;condition('name', 'MODULE_NAME')
    -&gt;execute();
}
