To reboot the phone, you have to perform a soft-reset. Press and hold the volume-down-button and the power-button at the same time for at least 10 seconds. This will trigger a power-cycle and the phone will reboot. Once fully booted, the phone may show strange behavior, like complaining about mail-accounts, showing old text-messages, inability to load https-websites, etc. This is expected behavior, because the time-settings of the phone are incorrect. Just wait a few seconds for the phone to get a data-connection and have the date/time synced. After that the strange behavior will stop automatically and normal operation is resumed.";
