[Unitree Go2] Go2 not standing up

Hello guys, can someone help me, i was trying to connect my go2 pro robot to a sensor and the my computer, so i used this command
“sudo ip addr flush dev eth0
sudo ip addr add 192.168.1.10/24 dev eth0
sudo ip link set eth0 up”
inside the robot. after using this command, the robot fell down and since then, it has refused to stand up again. it is only blinking green light and a sound of the motor that is trying to start. please can anyone help me with what to do in order for the robot to stand up.

Oh, it seems the ip has permanently changed due to which it cannot communicate. Some steps have been missed which caused this. This too would cause the fall. Please contact support@mybotshop.de. Im not sure if it can be recovered without reflashing.

i have reached out to them but no response, how can i reflash the robot
