Issues with service pack rollback

[aemninja]

Hello Community - There are some issues with rollback of the installed service pack (6.5.11) on our AEM instance. We have followed the below forum to rollback to previous version but no luck. Even after the uninstall of the service pack or installing the /lib folder taken from the other environment and restart the instance, the environment is not accessible.

Can someone tell me process to rollback the changes?

•  Please restore the instance from your backup or EBS snapshot if you have.
• What's the error the you are getting in the error log while accessing the server ?
• Did you see any error while restarting the server ?
