How do you know you have an update - Do you have Java installed are the drivers installed

Hi,

Since it looks like you are using Windows XP, I suggest that you check the following thread for some tips that you can try:

Looks likes your phone is locked.  Please unlock the phone and try connecting. That should do the trick.

hi,

I can#t connect to PC Companion either. I think it's because I get an error message during installation of of the MTP drivers, saying that it is not a regular MS DOS application.

I use Windows 7. How can I install the phone drivers properly to connect and update my phone?
