Xperia T completely dead

[scotteh]

I've had an Xperia T for about a month and it randomly died today. It turned off and I just assumed the battery ran out so I plugged it into my computer and left it. Hours later it was still dead.

The LED doesn't come on when I plug it into the wall or computer. My computer doesn't recognise it. Pressing the power + volume up buttons for 5 seconds makes the phone vibrate once but nothing happens. If I keep holding it for a few more seconds after the vibrate, it will vibrate 3 more times then nothing.

Any ideas would be much appreciated

Thanks

I had the same problem with my Xperia Z yesterday, try this

connect your xperia to a wall charger > press and hold power & volume up for 5 seconds > leave it charging for 1 hour even if you don't see any sign of charging > after one hour repair the phone with SUS 

install SUS > restart your PC > run SUS > follow the steps > connect your phone to the PC > press and hold power & volume up once the phone vibrates release both keys and only press and hold volume down

You have an alternative but you will have to flash your phone with flashtool or flash a kernel on fasboot 

or 

you can take your phone to a Sony repair center

Thanks guys. My phone is back on now, I just plugged it into the wall and left it until the green light came back. Then I turned it on and everything seems fine now.

Is this likely to happen again?

Its possible but not likely
