thank you, you were very kind, good work and have a good day ! Fabrizio

Yes i wrote, the instructions on how to reset the bootloader are simple? Just insert the key into the byboard board into the 6 connectors pin holes near the reset button?

Hi, I bought the robot from Amazon in 2022, there is no bootloader reset kit in the package.

if I press the reset button nothing happens, it doesn't produce any sound

Same problem with COM5

Hi in english working fine, thank you

Sorry i seemed to remember that he stood up on his legs without giving any command

installed firmware, performed calibration but now the robot does not lift when I switch it on

Thank you, i solved it by re-installing the firmware

thank you
