The attached latex produces header of page 2 and page 4 to look like
where I would have liked "CONTENTS" to be "Contents" and "Chapter 0: Rresumé" to be "Rresumé".
All the following chapter headers should still be "Chapter 1: Something".
Question
Does anyone know what I am doing wrong?
Latex
\documentclass[a4paper,12pt]{book}
\usepackage{fancyhdr}
\usepackage{titlesec}
\usepackage[nottoc]{tocbibind}
\pagestyle{fancyplain}
\renewcommand{\chaptermark}[1]{\markboth{Chapter \thechapter{}: #1}{}}
\lhead[\fancyplain{}{\bfseries\thepage}]
{\fancyplain{}{\bfseries\rightmark}}
\rhead[\fancyplain{}{\bfseries\leftmark}]
{\fancyplain{}{\bfseries\thepage}}
\cfoot[]{}
\addtolength{\headheight}{1.6pt}

\cfoot[]{}

\renewcommand{\chaptertitlename}{}
\titleformat{\chapter}[hang]{\normalfont\huge\bfseries}{\chaptertitlename\ \thechapter:}{1em}{}
