\begin{enumerate}
\item Get a copy of the original \playerman{} \playertype{} firmware from
  \url{http://www.cowonglobal.com/zeroboard/zboard.php?id=C08&bmenu=support}.
  It has to be of the same version that is currently installed on your \dap{}.

\item Build the mktccboot tool or download a binary for your operating system.

\item Build the bootloader (\fname{bootloader-cowond2.bin}). Pre-built binary
  is available at \download{bootloader/cowon/d2/bootloader-cowond2.bin}.

\item Patch the bootloader into the \playerman{} firmware using mktccboot:
  \begin{code}
    mktccboot D2N.bin bootloader-cowond2.bin D2N-patched.bin
  \end{code}
  \note{The filename depends on the firmware version and hardware revision as
    shown in the table below (for the \playertype{} use the file found in folder
    ``\fname{1}'', not ``\fname{0}'')
    \begin{table}
      \begin{rbtabular}{0.6\textwidth}{XXX}%
        { \textbf{FW / HW} & \textbf{\playertype{}} & \textbf{\playertype{}+}}{}{}
        \textbf{1.xx, 4.xx} & \fname{D2.bin} & \fname{D2\_P.bin} \\
        \textbf{2.xx, 3.xx} & \fname{D2N.bin} & \fname{D2N\_P.bin} \\
      \end{rbtabular}
    \end{table}}

\item Copy the output file (``\fname{D2N-patched.bin}'' in our example) to the
  root of the \daps{} internal memory and rename it according to the above table.
