Hi Ateyi
You are encountering the error due to a bug below
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvg37458/?rfs=iqvred
Issue boot command on rommon mode - It will boot with the available ios on the flash.
Once it boots, you need to upgrade the firmware to the unaffected like release 16.9(1r).

I dont think there is a priv mode on rommon. It has to boot on an image then you can go to priv mode. Issue boot command.
