actually, i have the same problem that just occured yesterday except i was just using my phone normally when it happened! I didn't flash it , but I was just talkin normally with my friend until it turned off. I tried turning it on after, and i get a white screen and it freezes at the sony logo afterwards. now, my phone doesn't turn on at all, even after i "tried charging" it (the charging screen doesn't even show anymore. But when you say the red led light, is it the light on the bottom right side of the phone? because mine flashes when i try to turn it on by pressing the power button, but the phone just doesnt turn on at all.

i'm a noobie to these phone flashin and stuff, anyone else know what the problem is?
