If the Nokia N97, N97 mini or C6-00 device doesn't boot up properly and a hard reset is needed, try the following key combination:
- Open the slide
- On the keyboard, press simultaneously Shift (left) + Space + Backspace and press the Power button
If the hard reset is successful, the device is reset to factory settings and boots up prompting for the country, date and time settings.
If the device cannot be reset, it may be faulty and needs to be sent to Nokia Care Point for repair.
