I have an Xperia T on O2. I got it this week and it said in my notifocation bar that i have a new softwear update (0.1.A.1.141) and that i needed to connect to a computer to do this. So i installed the Sony compaion softwear and connected my phone. I then went on to a support zone and clicked update. It downloded the update to my computer and it then sid that it was prepearing the update for my phone. BUT then my phone just turns its self off and starts charging when it has 100% charge. The computer then says that you have to dissconet usb from computer, then from phone, turn off phone, connect usb back to computer and then hold down the down volume key and incert cable into phone. I then did that and it just starts charging again. Please can somone tell me what to do
