[Unitree Go1] Go1 Battery not working

Hi,
I have the Go1 and was testing the different controllers. I was testing the white controller which is called emergency braking i think. And clicked one of the buttons while the battery was of i think.
When i tried powering it back on it just flashed the battery level. ( Which was full ) And when i tried it again it didnt show any light. It will not turn on and i have tried charging it without luck. What should i do

@Azib Could you please check.
