You can also add earlier platform versions to the list if you want to go back further. See:

WAY Behind in Software Updates (2.2.3)

Since no one answered your questions.... Use this endpoint to download any final version of past major versions. Where 234 = 2.3.4, etc... change to any version you want /hub/advanced/downloadPlatform/234 Once downloaded it will be available in the Diagnostic tool under "Restore Prior Version..." Was it referring to restoring a backup or restoring the platform? I suspect it may have been saying you cannot roll the platform back. The actual database backup can typically be restored.
