HOW TO MOD OR COSTUMIZE OPERA MINI FOR URSELF
all you have to do is to follow these simple steps
having said that now lets go there! or rather
come with me guys
REQUIREMENTSOperaMini 4.2 UNmodifed please download
directly from opera website
HxD hex editor(this i know u already ve from my
other thread on cracking java)
WinRAR for extracting a.class, f.class and v file
Computer(most important of all)
pngout.exe program
Paint
Pixelformer
Splash image in .png format(as time progresses i
will let us know how to do this)
Scientific Calculator (u can simply use the one in
ur system cos that is what i used through out)

please use without internet connection)
Topic 1. Embedding the Skin on v file1. Open v file and the skin (pic u want to use
in .png) file in HxD hex editor.
2. Highlight all the contents of the skin file and
copy it. You may press Ctrl A then Ctrl C. Take
note of the value in Lenght indicator. This is the
filesize of skin in hexadecimal.
3. Goto the v file tab and press Ctrl F. Search for
"png" text string.
4. Highlight the bytes starting from 89 50 4E 47
0D 0A 1A or the address 00001DA0 x 0E until the
Lenght indicator reaches C7C.
5. Press Ctrl V to embed the skin image on v file.
Now we're ready to change those addresses
embedded in the v file. Change only the
addresses enclosed with the blue boxes.
These addresses are for unmodded v file and
often times changes if modifications were already
done on the v file.
6. Open the scientific calculator and put it in hex
mode. If the filesize of the skin in hex is greater
than C7C then subtract C7C from the filesize of
the skin. If the filesize of the skin is less than C7C
then subtract the filesize of the skin from C7C.
Take note of the the answer.
Add the answer in procedure 6 to the address
enclosed in a box in procedure 5. Change
them accordingly to the result of adding or
subtracting those embedded addresses
7. Save v file and exit HxD hex editor.
8. Open operamini 4.2 with WinRAR and drag the
v file from the desktop to operamini...jar.
9. Click Ok and close WinRAR.
10. Finally, install your modified Operamini...jar
on your phone or use microemulator on your
computer to test your work.
Topic 2.
Changing the Welcome Page1: First, we need a webpage address. For this
guide I will be using the address "http://
www.mozilla.com/en-US/firefox/firefox.html" as
my welcome page.
2. Open v file with HxD editor. Click the Edit menu
then click on Replace. At the Search for box, type-
in "http://www.operamini.com/firsttime/4.2/"
and at the Replace with box, type-in the URL of
your welcome screen. Click OK.
3. Highlight all the text that are red color and
takenote of the Lenght value. In the screenshot I
got a 31 hex.
4. Change the hex value of the character just
before "http" to the of length in procedure 3.
5. Now where done with editing the URL of the
welcome screen. The next thing to do is to
change the embedded addresses on the v file. If
the length value obtained in procedure 3 is equal
to 27 hex, then proceed to the next procedure. If
the length value obtained in procedure 3 is greater
than 27 hex, then subtract 27 hex from the length
and add the answer to each of the boxed
addresses. If the length value obtained in
procedure 3 is less than 27 hex, then subtract it
from 27 hex and subtract the answer to each of
the boxed addresses.
6. Save v file and exit HxD.
7. Test your mod.
