installing java

I hope this tutorial will help you install games on your cell phone. This works perfectly on samsung sgh z170. (http://forum.gsmhosting.com/vb...p?t=609664).

Each game should have a jar and a jad file.
First you need to put your jar and jad files in one folder and save it under Local Disk (C ).

1. Download Driver & File Explorer from
(http://forum.gsmhosting.com/vb...p?t=609664).

2. Uncompress (or extract to) SAMSUNG_Composite_USB_Driver and execute Setup.exe.
3. Connect phone to PC. First time you should be prompted with a 'device installed and ready' message.
4. Execute TkFileExplorer_2.2.exe
5. Go to Settings - COM.
6. Scroll down Port window: You should get just one COM option. Choose it and press OK.
7. Go to File - Connect. You should see the File System Tree at TkFileExplorer bottom half side.
8. Go to /Exe/Java or you can go to Media/Games.
9. At TkFileExplorer upper side open Local Disk ( C ) and select JAD/JAR folders which you have saved previously and drag and drop them under Java or under Game folder.
10. Then under File menu choose disconnect then exit.
11. Dial *#6984125*# on your phone. This will open the 1.software version, 2. pre-configuration, 3. network and call settings, 4. internals
12. Choose Internals (Master Key: *#9072641*#)
13. Go to Storage Settings and select Update Media database, Update Java DB and Update application database.
14. Open the games folder in your phone and start the game!

Enjoy! ...and save money!

NOTE 1:
You do not need to change Samsung USB mode to Qualcomm. Leave it at its default Samsung mode (if you do not understand this just do nothing )

Note 2:
Be careful!
Once you are inside TkFileExplorer dont delete any built-in folders as this may damage your phone. Also before physically disconnecting the cable from your phone, disconnect it first from the File menu

Note 3:

If the game has only a jar file, you have to make a jad file from the jar file by using the java maker which you can download from (http://www.softpedia.com/get/I...Maker.shtml)
All you have to do is to drag the jar file into the "Make Jad" window and a jad file will appear in the desktop.
