sometimes you just need to reset with back button and start over.. hold back button in for like 40 seconds and release and come back in 5 minutes..if it does not reset you can hold 40 seconds....then unplug power.. keep holding in button and after 40 seconds plug in power keep holding and finally release after 40 seconds.....or you can also try to get in by tftp program which worked a few times and saved my butt..
