5. Problems may be encountered
If the firmware update fails, please try the following:
1. Use a different USB port. We recommend using a USB port on the back of the desktop computer first. If the issue persists, try connecting the device to a USB hub with an independent power supply.
2. Use a different USB cable. We recommend using a cable no longer than 1.5 meters. Please connect the device directly whenever possible, and avoid using adapters or converter cables.
3. Try updating the firmware on another computer.
4. Try entering DFU mode, then perform the firmware update again.
