Samsung Star 3g Install Full Screen Java Games/Applications

Hey all,

I am back with another great tutorial about how to install Java games & application in Samsung  Star 3g with full screen. Because by default it comes with a virtual keypad, which is not necessary in touch screen applications & games. So have fun with this trick.

Here is step by step procedure for installing full screen games.

1. You need to first download star 3G games or application that supports touch, you can get it from google. Any touch supported JAVA games/ apps will work with it.

2. Then Open the .JAD file with notepad. You’ll see something like this.

Manifest-Version: 1.0
Created-By: 1.4.1_02 (Sun Microsystems Inc.)
MicroEdition-Configuration: CLDC-1.1
MIDlet-Name: Roland Garros 2008
MIDlet-Icon: /icon.png
MIDlet-Vendor: Gameloft SA
MIDlet-1: Roland Garros 2008, /icon.png, GloftRGAR
MIDlet-Version: 1.4.7
MicroEdition-Profile: MIDP-2.0
MIDlet-Jar-Size: 576987
MIDlet-Jar-URL: RolandGarros2008.jar
Nokia-MIDlet-Category: Game

3. Then add this lines at the bottom of this file text.

MIDlet-Touch-Support: True

4. Now it would look like this :

Manifest-Version: 1.0

MIDlet-Touch-Support: True
MIDlet-Jar-Size: 576987
MIDlet-Jar-URL: RolandGarros2008.jar
Nokia-MIDlet-Category: Game

MIDlet-Touch-Support: True

5 . Then save wfile & install files by using unlocking Smasung star 3g Procedure for installing Java games & apps.

6. Thats it. If this does not work you can use it following four lines instead of above line.

NUMPAD: true
MIDlet-Touch-Support: true

Hope this tutorial will hekp you. Comment here is you have any problem with this trick. Also we love appreciations, is this one has worked for your Samsung Star 3G.

      If it is not there add it in a jar file.

  15. Hi. Thanks for the installation instructions. I can install any java app on my S5603. However, I have one basic question for midlet touch support. How do I enable it. I mean how do i edit the already installed jar or jad files ? They do not show up with my phone connected as mass storage. Also, TK explorer does not allow editing or opening jar files. Is there some tool (some explorer) i need to use ? One solution I see is copying the java files back to the PC, editing them and then copying them back to the phone. Is that my only hope? Thanks in advance.

  16. Hi,
    Thanks man for the installation instructions, they really worked well. but there is one problem i could only hide the virtual keypad with this process but i am unable to run the game in full screen mode. there is some blank space left at the bottom of the screen instead of virtual key pad its really annoying, please help me with this.

    After downloading, the game works fine but motion sensor do not work even after turning motion sensor option on.

  30. New Method
    Using Minicommander (FREE and NO ANNOYING ADS)

    Steps in Mobile Browser:
    Open from your mobile browser.
    Search for Minicommander in the search box. (If not found try ‘Mini Commander’ instead of ‘Minicommander’, or simply go to from ur pc and search for mini commander, get the quick download code and then download it using ur mobile)
    Click Minicommander in the search result.
    Now click Download Minicommander, It will be automatically installed in your Phone.
    Steps in PC:
    Download the necessary game or application to your PC.
    Let us consider you have downloaded Mario.jar.
    Create a folder called ‘Mario’ (Consider G:\JavaGames\Mario)
    Copy the Mario.jar file to the G:\JavaGames\Mario.
    Download and install JADMaker in your system.(Note : JADMaker needs .NET Framework 2.0 or above, you can download it from microsoft website)
    Run JadMaker from the Start Menu.
    Open the folder G:\JavaGames\Mario
    Drag the Mario.jar to the JadMaker window.
    New .jad file called Mario.jad will be created in the folder.
    So your folder G:\JavaGames\Mario will have Mario.jar and Mario.jad.
    Connect your mobile to PC:
    Now connect your phone to PC using your USB cable.
    You can either choose PC studio option or you can choose Mass Storage option. (These options will be provied only if you have selected the option Menu -> Settings -> Phone Settings -> PC Connections -> Ask on Connection)
    Copy the folder G:\JavaGames\Mario to your menory card. For example consider you have copied the ‘Mario’ folder to a folder called ‘Applications’ in memory card.
    Now disconnect your phone from PC.
    Steps in your Mobile :
    In your phone goto Menu -> Application ->Games & more -> Minicommander
    It will ask ‘Minicommander may access read user data continue?’
    Give ‘Allow, ask once’.
    Minicommander’s UI will be like this.

    Open /filesystem/ in the left hand side.
    Open /Mnc/Applications/ in right hand side
    select Mario folder in right hand side.
    Press ‘5’ in the number pad at the bottom of the screen.
    This will copy Mario to /filesystem/
    Exit Minicommander.

    Final steps to update Mobile Java DB:
    Now open up your key pad and enter *#6984125*#.
    This brings up Admin Settings.
    Choose INTERNALS and enter the master key *#9072641*# and confirm.
    This brings up Internals screen.
    Now scroll down and choose Storage Settings.
    First press Update Java DB
    Then Update App database
    Then Update Media database.
    Finally Create AX Dat File.
    Exit the settings by pressing the Call Cancel key.
    Thats it.
    Go to Menu -> Applications -> Games & More.
    You can see your newly installed Mario Game.
    It will be named as something like ‘Minicommander/mnc/Mario’, just rename it to ‘Mario’….

    Cool…… Similarly you can install any number of Applications and Games….
    Hope this helps you….

    Please comment if it works for you…. 🙂
