Since I got Xperia T updated to Android 4.3 I have been through problems. The problem now is that the phone can't be charged when it is turned off and I got my battery completely drained resulting in a dead phone that can't either get charged or turn on, only blinking red LED when power button is pressed. I have tried many methods like putting it on charge over night and even 24 hours, putting the tape on power button while charging (it turns on though but as soon as it pass the boot animation the battery looses its charge and it turn itself off and this keeps happening). Now I'm really wondering if someone here had faced such problem and was able to work it out so please share what you did.
