LG VM510 filesystem innards, tricks, and treats

Thanks for all your work on this guys!

haven't located the browser at this time. I bet it's written in BREW. I'll go digging... my priority was to write a J2ME downloader app, the only freeware I've gotten to work pulls down 64k of a file and stops there. Assume they haven't accounted for page limits or it's written for midp 1.0...I hate the lousey-browsers which come with all the mobiles I've used.

That would make sense--there's no Java splash screen on the Netwave browser. I hadn't noticed that before, heh...

Here's the complete guide to user ringtones on the LG Rumor Touch

The user ringtones are stored in the directory mms/Sound on your RT.
They can be just normal MP3 files with an MP3 extension.
They are indexed by the file setas/mmsRingerIndex.map on your RT.

setas/mmsRingerIndex.map is little-endian, 17202 bytes long

struct
{
   WORD count; // number of active index entries
   struct
   {
      BYTE index;         // 0 to 99 in sequence
      BYTE something;     // 0x54
      char filename[170]; // "fish.mp3" for example
   } links[100];
}

Here's a little Windows command line utility for generating mmsRingerIndex.map

[Only registered and activated users can see links. ]

1) copy all your .mp3 ringtones to the mms/Sound directory on your RT

2) generate a mmsRingerIndex.map file using a list of the filenames without paths.

lgring fish.mp3 cows.mp3 birds.mp3

3) copy the generated file to the setas directory on your RT

4) Go to the menu Settings/Ringer/--whatever--/My Audio and assign your ringers.

Note: The order of the filenames to lgring.exe is important.
If you have the first entry assigned to a ringer and you change the filename
then that file will be assigned to the ringer, i.e. assignments are made by index number.

nice info, Renate! I appreciate it and will mess around with it soon.

If anyone wants to modify the icons which show up for MMS attachments (downloadable or not), they are stored as .jpg files inthe directory
/mms/default_img/
with fairly descriptive names.
I've lost track of the character set I found buried in the phone filesystem, but I'll post the location for it as well once I find it again.

The opening menu on the RT is configured by the file /homescreen/shortscuts.dat (yes, that is "shortscut").
It's a simple file, consisting of 5 tab-separated fields, terminated by a *nix-style 0x0a.
1) A link for language-dependent titles
2) A text title
3) A link to an icon
4) Another link to an icon
5) A command
The entire file is terminated with one null.

You can obviously rename the entries.
You can remove the "Add" if you think that it makes no sense there.
You can specify a URL as the command. This is probably the most useful feature so far.

VarLabelID=0&Arg=  YouTube  home_web_n.png  home_web_n.png  http://www.youtube.com/

Note: you must use tabs, not spaces as shown above

The home menu only allows a total of 15 links (including "Main Menu").
You can remove the "Add" selection.
Deleting any selection will reinstate the "Add" selection.

here's how

way too cool.
since my last hard reset of my handset, I hadn't emailed myself my text message ringer again yet, so both the directory /mms/Sound and the mmsRingerIndex.map file didn't exist on my handset when I tried this.
created the directory and put my single .mp3 in there, and generated a .map with this lovely tool, and sure enough, my ringer was not only accessible but also shows its correct filename instead of the date-based filename the phone assigns MMS downloaded ringers using the [Only registered and activated users can see links. ] method of inserting ringtones.
not to mention the .mp3 to .qcp filename extension change is now unneccesary.
Renate, you rock! Thanks to you I now have custom wallpaper which looks the same whether the slider is open or closed, and I can read the title of my custom ringtones! I'm still trying to find where the start menu icons are hidden so I can insert my own or at least modify the originals, but I haven't seen 'em yet.
