Are you still getting this message when trying to recover the switch? Or has it changed to a different message. If you could include additional console output to help show the current state of the switch. Please detail any steps you tried to follow, but ran into error messages, or just in general steps that were not able to be completed.
This additional information will help guide our troubleshooting efforts.
