How To Hack J2ME

Monday, June 25th, 2007

If you get a J2ME game or application for your handset in trial version, you can hack this. The requirements:

  1. you must be familiar with java, and j2me
  2. Decompiler Java, I used the free one Jad
  3. Java Editor, used eclipse
  4. Java Wireless Toolkit, you can download from here
  5. WinRAR, compress tools

After you get the applications of J2ME, find the file with .jar extension. Uncompress it with winrar. in the uncompress you will find the the files with .class extension that is class file. find the main class. To find the main class you can get this information from xxxx.jad file, it’s text file open it and find variable name MIDlet-x, x is indicate the x-th midlet in the jar files. It may be only 1 class. the format of MIDlet-x value is: [name],[icon],[main class]. Get the main class, and decompile it. by using jad. eq:

    $jad -s .java -f -ff Main.class

You get Main.java, It’s the java source file, but the class file is come from obcuscaste, so the source not read easly all fungction and variable in short alphabetic such: a, b, c, etc. You must gues the actual function. The clue you can get from label.

Create new Procject on WTK. put java file from decompile to src directory and the .jar into lib directory, process .jar file: open with winrar and remove all files that extension no .class, and remove the Main.class

Others file that uncompress from jar file insert into res directory.

Try to build in wtk wheter it can be build.
