\subsubsection{Installation}
\begin{enumerate}
  \item Download 
  \opt{iriverh10}{\download{bootloader/iriver/H10_20GC.mi4}}
  \opt{iriverh10_5gb}{
    \begin{itemize}
        \item \download{bootloader/iriver/H10.mi4} if your \dap{} is UMS or
        \item \download{bootloader/iriver/H10_5GB-MTP/H10.mi4} if it is MTP.
    \end{itemize}}
    \item Connect your \playertype{} to the computer using UMS mode and the UMS trick%
        \opt{iriverh10_5gb}{ if necessary}.
    \item Rename the \opt{iriverh10}{\fname{H10\_20GC.mi4}}\opt{iriverh10_5gb}{\fname{H10.mi4}}
        file to \fname{OF.mi4} in the \fname{System} directory on your \playertype{}.
        \opt{iriverh10_5gb}{\note{If you have a Pure model \playertype{} (which
            does not have an FM radio) it is possible that this file will be
            called \fname{H10EMP.mi4} instead. If so, rename the \fname{H10.mi4}
            you downloaded in step 1 to \fname{H10EMP.mi4}.}}
    \note{You should keep a safe backup of this file for use if you ever wish
        to switch back to the \playerman{} firmware.}
    \note{If you cannot see the \fname{System} directory, you will need to make
        sure your operating system is configured to show hidden files and
        directories.}

  \item Copy the \opt{iriverh10}{\fname{H10\_20GC.mi4}}\opt{iriverh10_5gb}{\fname{H10.mi4}
      (or \fname{H10EMP.mi4} if you have a \playertype{} Pure)} file you
      downloaded to the System directory on your \dap{}.
