Enable IDU Mode

To enter IDU Mode, it is required to insert a PS4 IDU Utility disc in the console or to enable it in Debug Settings.

Via PS4 IDU Utility disc

No PS4 IDU Utility disc was ever dumped, although the PS Vita one was dumped and the PS5 one is proved to exist.

Via Debug Settings

You can enable IDU Mode in Debug Setting by selecting "IDU mode" then "On".

<list id="id_system_idu_mode" title="IDU mode" key="/SYSTEM/SPECIFIC/idu_mode">
<list_item id="id_system_idu_mode_off" title="Off" value="0"/>
<list_item id="id_system_idu_mode_on" title="On" value="1"/>

Via registry edit

Setting SCE_REGMGR_ENT_KEY_SYSTEM_SPECIFIC_idu_mode registry entry value to 1 should theoretically enable Idu/Kiosk Mode after rebooting.
