Now the upgrade is finished.
Typical Errors:
1. Invalid Port Number: in Device Manager, make sure you have the correct COM port
number for CP210x.
2. Wrong “.bin” file: make sure you have the correct “.bin” file for firmware upgrade.
3. Wrong downloader, you should use iOptron Downloader instead of the Flash
Downloader.
4. Use cp210x driver provided by iOptron. The newest version from SiLab may not work
properly for iOptron’s hand controller.
