I have Sony D6653, It was working well. I was chatting on messenger and downloading an app from google play, Suddenly my phone froozes and sometimes later it automatically show Sony logo and wait for 2 seconds and turns off automatically. Now when I try to power it just vibrate one time and show Sony logo and restart and again same thing. When I pluge in the charger, the red led glows and again same thing. Now please tell me what should i do. Plzzzzzzzzzzzzzzzz
Try reflashing the firmware using Xperia Companion from this website: http://support.sonymobile.com/au/xperia-… You will most likely have to lose data in this case unfortunately as it seems like the phone is bricked. It could be battery instead of firmware being corrupt, hard to tell at this stage.
