This option boots your system as normal without changing any settings or files.

2. Rebuild Database

This can be a usefull feature if you have lost files on your system for no apparent reason. Try using this feature to see if it can restore those files. This will also rewrite corrupted files within the database, potentially eliminating future issues. This feature should not erase any of your saved data or settings.
Deletes messages, playlists, changes made on "Information" screens, trimming information for pictures in "Photo", video thumbnails, video playback history and video resume information. This operation may take a long time depending on the type and number of data items.

This will format the memorycard, effectively erasing all data currently on it.

4. Restore the PS Vita System

Demo Mode

The demo mode at a PS Vita

[Available only via an external software (IDU) Cartridge]

It will show 'DEMO MODE' in the bottom right corner of the PS Vita, and said demo mode will hide most pre-installed applications.

To enable this mode: An external PS Vita (IDU) Cartridge is necessary to add the demo mode to a retail model.

To (temporary) disable this mode: Hold L + R + UP + START (for a few seconds)

Not much is known about the demo mode (aka. Kiosk firmware) of the PS Vita. It is just known, that temporary disabling it with restart the PS Vita on its own after 5 minutes, if the device is not running any kind of software (e.g. a game) and if it is not connected to an external power charger.

Updating/Downgrading the PS Vita will not remove the demo mode, the device remains a kiosk device, unless one removes the demo mode with the IDU cartridge which installed it in the first place.

2. Press simultaneously RTrigger + LTrigger + DPad Left + Square for a few seconds
3. Release those buttons then immediately press the start button
