[Unitree Go1] Bootup Failure, Active Torques

General Discussion
1

Hey all, our Go1 suddenly stopped booting up, after we ran a few trajectory tracking experiments on it.
The FL leg has had some trouble during bootup before, we noticed it has a puncture on its foot sensor, so we believed that it might be causing issues. Applying some generous tape to the puncture does nothing.
Here is the detailed scenario:
We use a fully charged battery and turn the robot on, while its laying flat on the ground, fans turn on(they hum quietly), and the legs most definitely have torque in them for some reason(even though the robot has not stood up). I dont think we can use any app or diagnostic tool, as the hotspot nor the Bluetooth of the robot turn on, hence the robot is not discoverable.

I noticed there are existing topics with the robot not standing up after bootup, but they still have connectivity with the robot, we do not have that. Any advice?

UPDATE: We found a loose wire on one of the motors. Re-soldered and its seems to get up frequently now. However, the Unitree WiFi is not turning on, we cant SSH into the thing as the Ethernet port is broken.

@Noor @Azib Could you please check the issue.

Dear @Rtics
According to the information you provided, to get internet access on the internal developer PC, you will need to use a USB Type-C hub together with a Wi-Fi adapter (as recommended here and here).

Once connected, you will need to SSH into the robot to activate the Wi-Fi connection.

You mentioned that the Ethernet connection is broken. Could you please clarify what you mean? Is it physically damaged, or is it a software/configuration issue?
