I guess you must have heard about java phones having the ability to minimize Applications, in a way that if you are browsing the internet and someone send you a text message, instead of closing the browser to go and read the message, you can simply minimize the application, after reading the message you can still go back to your browser and start from where you stoped. I know that you are still wondering whether it's really true.
Yeah it's absolutely true! You don't need to be in position of Apple phone, Symbian phone, android phone, window mobile etc.. before you can be able to minimize applications.
So, on this article, I'll be teaching on the above stated topic. The practical steps on how it can be done and equally how it can be undone.
1. Install Phoenix on your computer
2. Connect your mobile to your computer in PC suite mode, open the Phoenix (before opening phoneix exit PC suite on your computer using exit option in PC suite
[file exit] ) now open Phoenix and click on File -Scan Porduct.
3. Then Phoenix will find your cell phone and shows your phone information in bottom line of Phoenix.
4. Click on Product- Product File.
5. In the bottom of pop-up window click on Read
6. Turn to an option for Java TCK Support. It is 28th option in some mobiles, 48th in some other mobiles, if not 28th 0r 48th option scroll through options you will get some where in options after you got ''Java TCK Support''option.
7. In the right drop-down menu to select the Java TCK - ON (JSR75 R W).
8. Click-Write.
9. Close Phoenix, unplug the phone, shut down and then boot. At this point the certificate have all been cracked, If you need to undo or restore permissions, then follow the steps above "Step7" will be amended to default the first one
(JAVA TCK OFF) option.
10. There is the need of PPU files in this processs of hacking, just we are changing a setting in product file.
11. The product file will normally be inside the package u downloaded from http://allnokia.ru but NOTE: Only use PPU from package, because every different firmware version has different PPU you can use this method of hacking in minimizing java APPs also after hacking your phone using the given method.
Editing java apps for minimizing
*. Open jar file which you want to minimize on your computer using winrar,
*. there you will find META-INF folder open that folder in that folder you will get MANIFEST.MF file Open that file using notepad and add these line at last Nokia-MIDlet-no-exit: true after that save that,
*. press ok for every thing that asked,
*. now send that jar app to mobile and test it,
*. press red button(call end button) to minimize.
