Running new programms on early firmware is problematic, our robot dog cannot standing up or work under this circumstance.

1. Check software version using our mobile APP (Sport Mode). If software version not available, please follow the step 4.

2. If software version is Go1_2022_01_14 or earlier (sport mode <= 1.34.0), you need to update firmware following step 4.

3. If software version is Go1_2022_01_26 or later (sport mode >= 1.36.0)，simply update software directly.

4. Check your hardware version before updating firmware：
    Read hardware version using mobile app.
    Check the surface of the power port on the right side of the robot body. If the color is black, the hardware version is H0.1.7. If the color is green or blue, the hardware version is H0.1.9.

5. It is recommended to use cable connection to update firmware, but connecting WIFI("Unitree_Go1******") is also an option.
    When using cable, make sure your computer ip address is 192.168.123.xx，and visit 192.168.123.161:8080/update_firmware on browser (chrome prefered).
    When using wifi， visit 192.168.12.1:8080/update_firmware instead.
    If your hardware version is H0.1.7，upload and update CoH017_xx.zip.
    If your hardware version is H0.1.9，upload and update CoH019_xx.zip.
