After installing H-E-N then appropriate kernel (both latest versions) I accidentally tried to close the HEN program with the usb mouse. After I clicked close(the x) on H-E-N. My Nokia n900 turned itself off. Now whenever I turn it on. The Screen sticks on the Nokia logo for a few seconds then turns itself off again.The white light remains bright and on until nokia n900 switches off (Battery is full) I'm Very Worried What should I do??? Anyhelp would bring light to my day
