Download Java software to Contents Bank
On your PC, using your file manager such as Windows Explorer or My Computer, in C:\Program Files/LGGSM/LGContentsBank/Contents create a new folder inside the Contents folder, and call it Java. (The Contents folder will then contain 3 folders called Java, Picture and RingTone.)
Download and save into that new Java folder the Java software you want for your mobile. You must put the downloaded Java files in that folder, or it won't work.
Java software often comes as a duo - a .jar file and a corresponding .jad file. Both files need to be in that Java folder.
If, there's only a .jad file available, then unfortunately the following steps will NOT work as it's the .jar file which is recognised by the LG software.
If you only downloaded a .jar file, you should be fine provided you make the corresponding JAD file first. Use Mango's excellent free JadMaker software which can even batch process multiple JAR files. Note that the JadMaker makes a jad file in the same folder as the original jad file, so don't be fazed if you drag and drop and can't seem to see anything happening - just check in the folder. Make sure both JAD and JAR files are copied to the C:\Program Files/LGGSM/LGContentsBank/Contents/Java folder.
Edit configuration and transfer to Chocolate phone
Then, follow these steps:
1. Making sure that the Contents Bank program is not open (close it first if it is), in a text editor like Notepad open the config.ini file (on my PC at least, that file is located in C:/Program Files/LGGSM/LGContentsBank). Save a backup first just in case, e.g. save it as backup.ini or config.bak, whatever you wish. Remember in the File Open window you may have to change "Files of type" to "All Files" to open the .ini file.
2. Find the line in the PROG_SETTING section that reads "EXIST_JAVA=N" and change it to "EXIST_JAVA=Y" (without the quotation marks, but still uppercase).
3. Find the line that reads "MODEL_NAME=XXXX" (where XXXX is something, on my system it was L3100, yours may be different), and change it to "MODEL_NAME=KG800" (again without the quotes) or =whatever is the model number of your LG phone (though note my warning above that I don't know how well this works for other phones).
4. Now "File Save as" the edited file, remembering to change "Text Documents (*.txt)" in the "Save as type" line of the "Save as" box to "All Files" before you hit Save. (Or else it'll save it as "config.ini.txt" which will stop it from working).
5. In Notepad or other text editor again, open the downloaded .jad file (or the JAD file you made from the JAR with JadMaker, above) and at the end of that file in the last line paste the following line in:
MIDletX-LG-Contents: KG800
(or instead of KG800 whatever is the model number of your LG phone). Important: the model number here must match the model number in step 3, or it won't work.
6. "Save as" the edited file, again remembering to save it as "All Files" so it will save as a .jad file and not a .jad.txt file (as per step 4).
(To restore your backup later, just make sure you're disconnected, delete your edited config.ini file and rename your backup.ini or whatever you called it to config.ini.)
7. The order of the following is very important: if you change the order in which you do these things, it may not work. Do NOT launch LG Contents Bank yet, do NOT connect your Chocolate phone to your computer with the USB cable yet.
8. Instead first turn the phone on, and as mentioned, keeping the phone slider open at all times, activate the modem (menu Settings, Connectivity, Modem, Activate modem, Yes, then the back button a few times to get back to the standard "home" screen on the phone, what it looks like when you first turn it on. Do NOT close the phone slider, always leave it open.
9. Now you can connect the phone to the PC via the USB cable.
10. Then, and only then, open LG Contents Bank on your PC. You'll see a new Java icon pic underneath the music and pic buttons (thanks to what you did in steps 1 to 4 above)
11. Click that icon (there's also a Java option now in the View menu, but it just doesn't always work for me so I don't use it). You'll see that the bottom left hand of the window now lists the .jar files which you'd previously put in the Contents Bank/Java folder.
12. In the Contents Bank Tool menu, pick Option and under Setting, Port, pick "LG USB Cable" and OK. Then click the Connect button in the middle/bottom right of the window.
13. Once it's connected (there's nothing to confirm this really, just give it a couple of seconds), in the bottom left quarter of the window click on the name of the Java file you want to transfer to the Chocolate phone to select it. Then click the Download button in the middle of the window to start the transfer, and let PC and phone do their stuff.
Οι οδηγίες αφορούν το LG Chocolate αλλά εγώ τις δοκίμασα σε LG KG320 με επιτυχία. Δεν γνωρίζω για τα υπόλοιπα LG αλλά στο δικό μου υπάρχει περιορισμός στα .jar αρχεία έως 100kb. Ελπίζω να βοήθησα.
Καλή επιτυχία…
