Now the upgrade is finished.

Typical Errors:

1.Invalid Port Number: in Device Manager, make sure you have the correct COM port number for “Prolific USB-to-Serial Comm Port.”

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 PL-2303 driver provided by iOptron. The newest version from Prolific may not work properly for iOptron’s hand controller.
