My XL keeps on restarting everytime suddenly. It keeps on going, sometimes it restarts atleast 10 times again and again sequentially. Dont know what to do. I've cleared the cache, dalvik cache, flashed new ftf, used SUS, done everything i can do, but it is not helping... My mind is totally blank. Dont know what to do, please help me... 
Hi there,
Sorry to hear that, contact your local Sony Xperia Care for more informations.

You'll probably have to visit your Sony repair center.
I wish you luck.
OK, don't exaggerate "mani 90". It's not gonna be on repair for month...
I had mine XL on repair back in Sony , waited for 10 days and they get me a new one.
It's sad that there is so many XL's with software and, more problematic, hardware problems.I'm very disappointed with my Xperia.
Sony was respectable brand back in the day....They loosing it.
try not to use the SD card or replace it with another
I am not exaggerating . it happened with my friend,s Sony Erricson. Still, i bought sony only because of the brand name and Japanese origin.
But they have let me down.. Its very very frustrating. Now, my phone doesnt stay for a minute in normal mode. It restarts the second i draw the pattern to unlock it. Using it in safe mode from yesterday. i am resetting it AGAIN hoping for some miracle.. Lets see..
