plssss help me..
pcc says installation error while upgrading to ics
sus says unexpected error and doesnt start..
what to do??
So many users are reporting the same problem 
i guess something is wrong going on with the servers
Try to use this
SUS ( Sony Update Service) ... download and install it on pc and follow the on-screen instructions http://www-support-downloads.sonymobile.com/Software%20Downloads/Update_Service_Setup-2.11.12.5.exe
or
http://www.sonymobile.com/global-en/tools/update-service/
Both the links are same

naah..noo help..
same old story..''unexpected error..''
You should read it through carefully.
"sus says unexpected error and doesnt start.."
it says.."unexpected error the application will shut down"
I know, i have the same problem 
I get the same error.
The SEUS logs yeild this:
Tue Jun 26 11:42:48 PDT 2012 | Fetching generated static remotely...
Tue Jun 26 11:42:48 PDT 2012 | Fetching remote startup data from url <</span>http://emma.extranet.sonyericsson.com/ns/common/1/staticdata/staticdata.ser.gz
Tue Jun 26 11:42:48 PDT 2012 | Could not fetch remote startupdata:Failed to objectify from serial object input stream.
Tue Jun 26 11:42:48 PDT 2012 | Failed to verify local storage: Failed fetching remote startupdata
Manually downloding and extracting http://emma.extranet.sonyericsson.com/ns/common/1/staticdata/staticdata.ser.gz results in an "unexpected end of file", and forcing gunzip to dump to the console works for a while, but eventually gives this:
Loader_AIDt ♠SW_AIDtCust_AIDt ♦HWIdt ♣Modeluq ~ e ►▒
gzip: staticdata.ser.gz: unexpected end of file
So, it looks like SE has a truncated/corrupt file at http://emma.extranet.sonyericsson.com/ns/common/1/staticdata/staticdata.ser.gz
Please fix ASAP, my device is dead in the water without SEUS.
