I have an Osmo Mobile 2 which haven't been used in 2 years. Last time worked perfectly. It was stored in original package.
Obviously battery was empty, so I did a full charge. Device turned on, motors didn't move, phone was balanced, bluetooth connection OK.
I turned off and on several times. One time motors began to move like crazy, turned it off immediately. Turned on again, no signs of life from motors.
Buttons work (except joystick obviously), zoom and rec do its respective actions.
Light stays solid green.

Any ideas?
Thanks in advance.

As you can see phone is balanced. Device turns on and connects to phone but gimbal doesn't work. You can record and zoom using the buttons.
It was difficult to record with one hand and hold the phone with the other
