Probably your internal flashcard has corrupted data.

Try to manually update firmware (so it will restore boot sectors)
Download http://www.entourageedge.com/support...1.0/update.zip to the root of sd card.
Press and hold the menu button and the rotate button
While still holding the menu button and rotate button, press the power button to turn on the eDGe
Release the menu and rotate button 4-5 seconds after hitting the power button
The eDGe should enter an update screen displaying 'Update in Progress'... wait until it boot in android.
