This error appears to be quite commmon when upgrading to Android 2.1, yet there seems nothing posted on fixing it.
Is there a directory on the PC or phone which is blocking this?
Anyone tried it on a second PC?

I went to the web site and search for a download, but could not find it. It keeps saying that I should do it through PC Companion. Can you please give us a URL for this download.
PC Companion is normally found on your phone memory and will install when you connect your phone to the PC first time round.

The other one to try for updating is Sony Ericsson Update Service which can be found here

Yipppeee!!!! Thank you so much. This worked! I am now on Android 2.1
If you're with Vodafone and trying to update to 2.1 then you will have to wait because they have not released the software. Vodafone have sent me an email. confirming this. I have been advised by a T-mobile customer that she has been able to update her phone. The reason I upgraded (and spent more money) to a X10i was because I was able to update over the internet but Vodafone neglected to advise me that I wouldn't be able to do this.
how do you login in that app??? I mean where should I register to in order to have a username and password?
thanks iceboy, i have wasted a day with pc companion, and SE troubleshooting and on the phone to them and got nowhere, your option updated phone in about 10 minutes, cheers

i took off all the antivirus took down the firewall and used the update service and STILL SAME PROBLEM/... i get the bit where it says insert usb into phone while pushing on the back key.. NOTHING im just tired now of all this crap!
jezus christ im fed up!
I had the same problem using my XP x64 PC but when I re booted into my Windows 7 partition it worked like a dream.
I am finding that W7 seems to have solved a lot of the old niggling problems.
