I bricked my GF's X10 trying to install dual touch update yesterday.
I used the exact same process I did with my own X10 last weekend at right at end of process, I got error message.
Right at end of process, I get error screen:
The Update was unsuccessful
The installation failed
Please disconnect the phone and make sure that the battery is fully charged before trying again. If the problem persists, please contact support.'

The 4th time it happened, I never got disconnect phone message. Now I get a Sony Ericsson letters for about 1/10 of a second and then a picture of a white triangle with an exclamation mark in it over top of a dead phone!
I uninstalled SEUS and installed latest. Chose option Factory Reset & Update;
Same thing, it gets to very end of process and same Update unsuccessful message!
I Do NOT want to void warranty by installing non official stuff...
After 5+ hours of effing with it yesterday, I think I'm going to take it back to my service provider's retail outlet today. It will probably take 2+ weeks to get some kind of answer from them.
