I was trying to update software for Hamilton T1, after i had a message ( successfully completed ), then i rebooted it in Service mode instead of normal mode, then it started alarming and never stopped. the screen on and off. i was not able to get either into normal mode or service mode. even i took the batteries off and then put them back, its still the same issue. right now i can turn it off but whenever it turns on i have alarming and screen alternating on and off. anyone can help me out.
