[Q][SOLVED] Phone will not respond when trying to update

I have the Xperia T and I am trying to update to 4.3, I had tried to use flashtool, but the phone isn't recognised by the computer when I plug in the cable holding the down button. Now the update is finally here for me I tried using PCC but again having the same issue. I have tried two different computers and all the USB ports on them. I have also fully switched off the battery (holding down the power and up button keys for 10 seconds).
I am stumped as to what is wrong with the phone??
thanks
Can no one suggest anything I could try? I have a feeling its a hardware fault, but it seems like a strange one at that... I dont know if its related but the phone also sometimes doesn't wake from sleep, it seems to be awake but the screen is not on, which requires me to do a hard restart
I am really desperate! thanks

turn of your phone. open flashtool. do not connect the phone to pc. select the firmware and click on flash,. after a few seconds it asks for the phone to connect. the hold the vol - button and plug in the usb. release the vol - button after the green light turns on. this may solve your issue

I have tried this, and it still does not work
thanks for the suggestion though
Interesting update (well not really), but I did some troubleshooting and stuff and found that when plugging my phone into the charger when it is switched off, it doesn't respond either (i.e. boot up). So I have a feeling that its the actual phone with a fault such as damaged pin in the usb port that relates to power when the phone is switched off?

I have the same problem.
When the phone is turned off it won't charge, either wiht the wall charger or with the USB cable connected to the computer.
I've sent an email to SONY but they told me so sent it to tech support.
It's not very easy to do it where I am so I'm looking for some other options.
I also noticed it when I was trying to update to 4.3.
PC Companion isn´t a solution since it asks to connect the phone to the PC while turned off pressing the volume down button, even to try the repair.
Can someone help?
Found the issue here http://forum.xda-developers.com/showthread.php?t=2018466
Such a weird problem, but unplugging and reconnecting the battery solved all the issues I was having!

Have a look at the thread link above, very simple to solve just take off the back cover and disconnect the battery for a couple of minutes

Plug it into the charger, does the led light go on? Also try holding the power button and both volume buttons for 15 seconds.

I'm not 100% sure but if there is vibrating and no screen, you've probably bricked your phone.

Try to connect your phone to PC while pressing on vol. Up
And wait for blue light
If you see blue light ....
You have a chance
Note: be sure that your drivers installed on PC

Connect to pc to back your data up. Also does the touchscreen work? And did you drop your phone or something else?
the touchscreen doesn't work
debugging mode is not activated, I cannot transfer my data to the pc.
I had the touchscreen bug for some time and suddenly, the screen did not turn on. The phone did not fall.

If it still under warranty i would send it to where you bought it. Even if you dont have warranty try it because the device should not be broken under normal use.
keep pressing the power button and when your phone vibrates try and hit restart. i know your screen is blacked out but if possible just try and locate. it happened with me too and thankfully my devices' screen recovered. the pop up comes just adjacent to the power button. first option will be your power off and then just below will be your restart.
I already tried
the phone reboots well but still black screen
