I am just copied/pasted the solution posted for the following question.

My problem is that box does not appear in the center of frame.
Below is the snap shot of my code along with its pdf version

\makeatletter
This is make at (@) a letter. That is: allow \c@page to be the command with name c@page
with @ part of the name. In normal document code it would be parsed as the command
\c the punctuation character @ and then the normal letters to be typeset page.
\apptocmd
this is a command from the etoolbox package that app(ends) extra code to a command.
{\beamer@@frametitle}
This is the beamer command that is being modified.
{
\addtocontents{toc}
{\protect\beamer@subsectionintoc{\the\c@section}{0}{#1}
{\the\c@page}{\the\c@part}
{\the\beamer@tocsectionnumber}}
\bookmark[page=\the\c@page,level=3]{#1}}
\addtocontents adds the specified line to the table of contents, by patching it
to the beamer frame title command this will happen automatically every frame.
{\message{** patching of \string\beamer@@frametitle succeeded **}}%
{\message{** patching of \string\beamer@@frametitle failed **}}%
The etoolbox command lets you specify additional code to run in the case it found the command that is being modified or not. Here this is just used to give a suitable message.
\makeatother
Put @ back to being a punctuation character so internal commands can not be accessed.
This is a possible solution where absolute position via tikzpicture environment \node[<option>] (<label>) at (current page.south east){<content>} is used.
Code
%\PassOptionsToPackage{demo}{graphicx}
\documentclass{beamer}
%\usepackage{textpos}
\usepackage{tikz}
\setbeamertemplate{navigation symbols}{}
\begin{document}
\begin{frame}[plain,fragile,label=here]
\begin{center}
\includegraphics[width=3in,height=3in]{crocuses}
\end{center}
\begin{tikzpicture}[remember picture, overlay]
\node[shift={(-0.6cm,0.5cm)}]() at (current page.south east){%
\hyperlink{there}{\beamerreturnbutton{Back}}};

The code in the linked solution works as expected. The problem in your case is that you are using an old version of
beamerin which an explicit end of paragraph was needed before\end{frame}for commands such as\centeringto have effect. Add an explicit end of paragraph (a blank line or\par) before\end{frame}:I'd suggest you to update your LaTeX system.
