Want to edit firmware version, but need to be in Maintenance or inventory state, but already in Deployed state. How do i change it back.? Help would be most appreciated.
You cannot go back to the inventory state. You can refer system lifecycle here:
If you just want to edit the firmware version in Airvantage. Please follow these steps:
Go to Monitor → System as the picture below
Search for your system
On the monitor page, select More → Edit
Search for your desired firmware version in the field named Firmware& Applications and save.
