Hi there,
I'm a noob and my LG is my first 'proper' smartphone so bear with me. I've just had issues transferring files to/from my laptop via Bluetooth (it's a HP running Win 7 but I don't think that's the issue). I would only be doing file transfer via BT very rarely and just wanted to see if it was possible.
Basically I could 'pair' the phone and the computer but I couldn't 'connect'. Is this the same problem you had?
Anyway, I downloaded the bluetooth file transfer app and this didn't work either.
Finally I downloaded OBEX Commander - a small freeware program for the pc. With this installed and set to 'object push', I was able to connect to the phone and transfer the files.
Hope this helps, and if anyone knows how to fix the original problem I had more elegantly, please chip in.
For reference, I'm using a rooted LG P500 with the standard ROM and V10a firmware.
