http://www.sonymobile.com/gb/tools/update-service/ Try updating on a PC using the update service directly instead of PC companion.
I am trying to use the update service but on step 2 it doesnot check the software version when i hold the volume down button and connect the micro usb to the phone. It just starts charging the phone.
Is your phone recognised by the application?
It is recognized by PC Companion but no response on Update service
You can try disabling your PC's firewall/antivirus and see if that helps. Otherwise, try it on a different PC.
I tried on a different computer and it worked but it also states that you have the latest software and if you are experiencing any problem than you can update it.
So are you sure that there is an update for your phone?
Here is my detailed information of the phone
Model No: ST25i
Android Version: 2.3.7
Baseband Version: u8500-480202-R1G_EC14
Kernel Version: 2.6.35.7+

and the latest build is 6.0.B.3.184
