here's my thesis Latex files: http://www.mediafire.com/download/c7q8z4v6gv864rk/triet_thesis_clean.rar
Please help me to fix the error, I've tried all the things I can find with Google :( :
! Missing \endcsname inserted.
<to be read again>
\begingroup
l.52 ...}intopreamble]Deobfuscation}{{4.1.1}{xii}}
The control sequence marked <to be read again> should
not appear between \csname and \endcsname.

You have a wrong character in one of your labels:
\subsection{LLVM}
\label{subsec:LLVMDeobfuscation}
where, between LLVM and Deobfuscation, you have the Unicode character U+200E (LEFT-TO-RIGHT MARK) that somehow sneaked in.
Retype the label and you should be OK.
\usepackage{underscore} the '_' character in labels will cause this error. To fix this also use \usepackage[english]{babel}
For others if you have not tried to delete all the generated files from pdflatex and bibtex, then do that before any other changes, because it could be a compilation error.

I never wrote Vietnamese and don't know if it can be done with pdflatex. However, if I use xelatex instead and
\documentclass[a4paper,oneside]{report}
%\usepackage[utf8x]{vietnam}%% xelatex is by default utf8
\usepackage{fontspec}%% load unicode fonts
\usepackage{graphicx}
\usepackage{pdfpages}
\usepackage{suthesis-2e}
\begin{document}
...
I'll get a proper output with out any errors.
xelatex instead of pdflatex. Every editor ahopuld have such a button or topix for xelatex
xelatex
\ref{...} by copy-pasting from the argument of \label. If you type directly \ref{subsec:LLVMDeobfuscation} you can't get a correct reference.
If you use \usepackage{underscore} the '_' character in labels will cause this error.
To fix this add the following: \usepackage[english]{babel}
Here's an example to show the fix works.
\documentclass[10pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
% try commenting out the packages below
\usepackage{underscore}
\usepackage[english]{babel}
\begin{document}
The banana figure, see Figure \ref{banana_two}.
This is going to be a line with an underscored filename: Banana_getting_unpealed.png
\begin{figure}
\caption{Bananas.}
\label{banana_two}
\end{figure}
\end{document}
In some cases, malformed options in \includegraphics (from the graphicx package) will cause this error (! Missing \endcsname inserted.). One example is forgetting width=, thus \includegraphics[1.0\textwidth]{filename} instead of \includegraphics[width=1.0\textwidth]{filename}.
I am uncertain if this occurs in every case or just with particular documentclasses (beamer here) and in the presence of particular other packages.
