3. Start PC Companion again and try to do the SW Update of the phone.
I have just tried that on my x10i with no joy.I am on firmware 2.1 update1.
I open pc companion and it states new software, so I click to update then a new screen pops up to which I click start phone update another page screen pops up with estimated time etc which I click next ,next screen is about backing up contacts etc so I click continue
then the final screen tells me to go to Se website and the next button on the pop up is not highlighted only the cancel button can be used,going back to the SE site is no good as it is just the install for PC companion.
Any help would be great........
