Why my Xperia U restarting over and over again with some kind of flash I don't know what is that. Someone help me please! It stuck at Xperia logo followed by some kind of flash on the screen.

Hi Uliwooly,

Yes have tried removing the cards and battery in/out, still boot only displays Sony logo then Experia logo ona loop!! I can only stop it looping by dissconnecting the battery.

that seems to be a hardware issue and you will have to get it inspected by your Local support
