iphone keeps on rebooting it self darwin kernel loop

[pinkie71]

Hello All

Im just wondering is there any one can help me.
My iphone has gone into a continues loop when switching on darwin kernel version.

The screen stay blank and when switched on the apple sign shows on screen then darwin kernel version starts and then shows lots of data 30-40 seconds screen flashes crashes.
The apple sign is shown again and back to the same again and again until the battery is completely drained.

I can not reboot it as it will not let me if i plug it in to my computer it will not seem to register that the device is pluged in so i can not even restore it with itunes.

And help with this problem to resolve it would be great.

Thank you

When you plug it in are you able to hold down Sleep and Home for 20 seconds to get into Restore mode? If you are, you can just restore.
