Accessing OrientDB console for password Reset with Nexus 3.0.2

Hi together,
is there a way to get into the OrientDB with a console for password reset with Nexus Version 3.0.2 ?
I only find a documentation for 3.2.1 and newer.
It’s also a solution to upgrade to the newer version but I’m completely lost with the upgrade failures and cannot find anybody to help me. (see: Upgrade Nexus 3.0.2 to 3.1.0)
Thanks in advance!
