a few days ago i bought a xperia s , from 2nd hand market. and i used it for a month without any kind of problems. i rooted my phone, and i was using xperia SL' rom... yesterday i plugged the charger and went to sleep.. when i woke up in the morning, my phone was not on, i tried to switch it on but it didnt, i tried all resets, i mean, volume up+power button , i tried to connect it by usb , my pc couldnt detect any device.  .. No led, no vibration, ... when i tried the reset (volume up+power). i thought it will be a battery draining problem, so i plugged the charger 6-7 hours , but still no response.. plz help me!!!
