after the discharge of the battery in the device I can not charge the battery and turn on the device.
when device is connected via USB (to charger 5V 2.1A or to PC), we have:
1. led status - slow blinking amber (for about 20 second)
2. led status - slow blinking green and orange keyboard button is blinking
I took the battery out of the device - did not help.
I'm going to read documentation on compass... maybe there is a way to reboot or something.
any advice for me?
