I have a 4255 that I inherited in my new position and after failing to connect via conventional methods (SSH, telnet, IPS Event Viewer) I connected to the console. No response from the device. I cycled the power on the device and the only thing that comes up on the console is "Booting Device, Please Wait..." and nothing follows. Is there any way to hard reset the device to a factory default config if it will not come up to the CLI? TIA for any help
