When the D3 shows following severe symptoms,
use its recovery mode to restore the device.
- When it fails to conduct system updates.
- When it needs to reinstall a current rmware on the device to solve
system errors.
* It is recommended to try ‘Power on/off’ or ‘Reset’ before using the recovery mode.
This mode is the last measure to deal with critical problems.

How to use recovery mode

1. Turn on the device while pressing the Play / Pause button.
2. As the right image shows, the Play / Pause button needs to
be pressed until the device enters the recovery mode.
3. From the step number 2, press the home button and check
whether the following 4 menus show up on the screen.
Use the Volume(+/−) buttons to select the menu and run
the selected menu by pressing the Play / Pause button.

a previously backed-up le.
* If there’s no le while starting the menu number 2, 3, 4, error messages will show up and will not start installation.
4. When using the menu number 3, the same menu will show up again after nishing
installation. Then select ‘reboot system now’, and check the updated rmware version.
