| Title downgrading via [[Application_Manager_Services|AM]]([[Application_Manager_Services_PXI|PXI]])
| When a title is *already* installed, Process9 will compare the installed title-version with the title-version being installed. When the one being installed is older, Process9 would return an error.
However, this can be bypassed by just deleting the title first via the service command(s) for that: with the title removed from the [[Title_Database]], Process9 can't compare the input title-version with anything. Hence, titles can be downgraded this way.
| Bypassing title version check at installation, which then allows downgrading any title.
