Here are tools that you need if you want to
modify a java application (ie, Opera Mini,
2go,ucweb etc.).
1F. X-Plore (1.42):ile Manager that is used to
extract jar archives and edit manifest.mf’s.
2. Zntxhan (2.04):File Editor that is used to
edit .class files and other files. There are
also other files that are supported by
zntxhan. (python needed)
3. Image Designer (1.40):Image Editor that is
used to edit or create image files for icons,
skins and etc of a java file. (python needed)
4. JarBoom (2.0):Compiler that is used to
compile or pack the extracted java archive.
(python needed)
Thats it! For a basic need, that was enough. For
python based apps, you need the python installer
and the module pack to run those apps.

For other s60 such as s60v3. There are also
corresponding apps for your phone version of
the said apps on same name
or s40, I havent tried it yet but i think it is possible
though I see it a little harder. And we will not
settle on that. ;P
ls
I hope you get a little idea about the apps. Up next
is the detailed and step by step tutorial on how to
modify java apps
We will now start on the basic of modding. I will
teach you how I learned this stuff. So the sharing continues credit goes to my modding mentor CHRISTOPHER MARISTELA from phillipines
So let’s proceed.
1.Preparing the java file:for example we want
to modify an opera5 or 2go, we use
xplore to locate it, click it and we see a lot
of files. All we had to do is to extract all
files in JarBoom’s unjar folder using X-plore.
2.Editing the Manifest:Look for META-INF
folder and inside you will see a
MANIFEST.MF file. You can edit it with X-
Plore by pressing [8]. Edit the necessary
details you want to change (ie, MIDlet-
Vendor, MIDlet-Version, MIDlet-Name,
MIDlet-Info-URL, MIDlet-Description and
MIDlet-1). Make sure when saving, the
Save as unicode option is NOT
checked.
3.Editing the Class Files:Using Zntxhan, locate
any .class file via Listway. We need to edit
these to change the server and put a trick
on it. In Opera Mini 5 final the server is
located in f.class (this differs on every java
apps). You can use the functions of Zntxhan
to search for the string of the server in the
class. After editing, save and delete the
created .class_bak (which serves as backup
but we do not need this)
4.Editing the Icon:Here we will use
ImageDesigner, you can edit the i.png file
that was extracted to any design you like,
just make sure you made it small to fit in as
an icon, 50�is enough (I guess).
5.Compiling:After we had edited what we
needed to, we’re off to compiling the files
back into jar file again. In this case, we will
use JarBoom, choose Tools-Compile and
locate the manifest.mf inside meta-inf
folder and give name to your jar file, wait
until the packing completes.
That’s it! Try your modded om. If it installs, great!
You did it. This is all just for now, I hope you get
a little idea about modding and we will proceed to
deeper topics in future. Always note that, what I
post here was based on my knowledge about
this topic. We may have our own style or way.
Explore and you will learn.
