    Looks like my Juniper EX switch just keeps reboot cycling in the console to "main menu" I was able to recover from snapshot and get into the cli but not sure what to do from there.

    Hello Steven,

    after recovering from your snapshot, try to type on the CLI :
    request system snapshot


    It will copy your actual configuration on the main part and you will able to recover Junos from the main disk.

    Are you able to install the latest Juniper suggested version ?

    https://supportportal.juniper.net/s/article/Junos-Software-Versions-Suggested-Releases-to-Consider-and-Evaluate?language=en_US#ex_series

    Software upgrade documentation :
    https://www.juniper.net/documentation/us/en/software/junos/junos-install-upgrade/topics/topic-map/install-software-on-ex.html 

    Before the upgrade, try : request system storage cleanup
    Upgrade using : request system software add "link_to_your_package_path" no-copy force no-validate
