Hi, I have a Sony Xperia L C2104 which happens to have a booting problem. I was playing a game on my phone when suddenly the phone shutdown but itself and now it is stuck or happen to restart or shutdown itself. Sometime the phone start by itself but does not pass the Sony logo and sometime it by passes the Sony logo and then Sony Animation starts but sadly shuts down itself again. I have tried updating the phone couple of times even if it says it has the latest version. I tried to hard reset by pressing the Volume UP+DOWN and the power button but still fails, so thus I cannot get the boot menu/recovery option. I also dont know whether is phone has a unlock BL or lock BL and I dont know whether the phone can be unlock if needed.

Please HELP
