My Ronin S powers on correctly but motors just wont engage. I´ve been using it for a week without problem and last night on the set Ronin S stopped working during the shoot. Battery seems fine. But when I press motor button, LED blinks 1, 2, 3 without the beep sound. Now the motors just wont work. And when I try to connect to the ronin app a message with a disconnection appears. I appreciate any advise. I'm in local town in Cambodia and don't have access to get replacement.  

I tried to update firmware to 1.8.0.70 but it failed.
