3. What can I do if firmware update stuck at 20% and failed?

Here follows some suggestions for you to troubleshoot the problem:

    1. Check if the cable is original, since there's similar cable but without data transfer function, try using the original USB cable;

    2. Check if the CH340 driver is successfully installed in your "Device Manager" on PC, sample as below screenshot, make sure the driver exist and without any warning symbols(Small yellow triangle); If there's any abnormity, try re-install the software and please let us know;

    3. Try using mBlock5 web version for firmware updating;

    4. Select the correct USB port that connect with mBot2, DO NOT select "Show all connectable devices"
