@ammar:

At least with the EMP modem driver that LG supplies (on the GR500 disc - and seems to be the only one that even recognizes the phone) and my AT&T-branded firmware, nothing will stay connected over USB except for the GPRS data connection.

LG's EFS explorer gets disconnected shortly after connection, so I can't "get in."

This happens even with bootmode enabled.

Happy to hear results to the contrary... Smiley

EDIT: Ahh, haven't checked out the driver Ammar referenced - will give it a shot when I get a chance.

Note: Java application permissions are defined (and somehow stored) at install, so deleting the att.pol may not affect currently-installed applications, but I'm curious to know if you can install something new and if it works OK.

Well the att.pol is a set of permissions the phone needs to allow certain access points. So if you are missing that file, newly installed apps will not be able to access certain functions (I.E. A mini browser, such as Opera Mini, will not be able to access the connection point to allow to connect to the Internet, etc.). Now, to my knowledge, I have not heard of any major complications coming from removing it (Although if I remember right, it would brick the Vu if that file was not present).

SOrry folks, I've been doing other things lately and haven't gone back to playing with the phone yet.

That's what I did with Opera Mini. You'll get one "data charges blahblahblah" prompt per session, and that's it. Much much less irritating then getting that prompt every single time you send a request.

Also, deleting the att.pol did not help with allowing java apps to access the filesystem...as far as I can tell.  I tried to reinstall liteftp onto the phone, but it did not have read access. But there were some other things I was going to do and I never got to it. I've been too busy working on my website.

Installed it, what now ? What should I do ? (What software should I run etc.)

@Tongle, could you guide us on how you accessed the file system ? I'm familiar with OBEX, so you probably won't have to detail it a lot.

I used obexftp.

Pair the phone with the computer using bluetooth, then I would issue commands, such as obexftp -c / -l, to list the contents. For some reason though, only 4 SETPATHs are successful before it fails, so I can't get into a 4th subfolder. NOt sure if this is the phone, or if it's a bug with openobex.

To get beyond 4 layers deep, you'll have to alternate forward slashes (/) with backslashes (\)
I found that trick in the comments of one of the early KU or KF series Sony Ericsson phones with regard to BlueSoleil 1.6

It might work for openobex, not sure.

@Tonglebeak:
Do the carrier-supplied applications still work OK?  (IM, Yellow Pages, etc)
I'm very worried that without the policy file any new carrier-signed downloads (like from MEdia Mall) won't get proper permissions.
Also to verify, your carrier is AT&T, correct?

@ammar:
The USB modem drivers are phone-specific as the USB device itself has different identifiers.  We already have a working LG modem driver for the GR500/Xenon from the LG PC Suite CD, so that's covered, though it seems cable connections differ in behavior between Rogers and AT&T firmwares.

@sumo:
Appreciate your attention and sharing your knowledge!
The GR500/Xenon definitely has a main SWF-based interface, along with various PAF and PXO files that are mainly graphical in nature, as you say.

I'll post a map of the AT&T firmware's filesystem here in a few... need to transfer the file to an accessible machine.

Interesting...  Keep us updated, especially if you download/purchase a program that accesses Internet or GPS from MEdia Mall.

Well, the new thing I've been working on is faking certificates. I have a signed midlet ready to roll, but for some reason the phone states "Authentication failed" Sad

Perhaps one of you can figure out why shit doesn't work. And I'm having a hell of a time getting my fake certificate onto the phone (can't download it for some gay reason).

Technically JARs are Zip files.  But specific MIME types are needed to do direct-to-phone download.
