Upgrade Failed

There are two problems that can occur when an upgrade fails. Flirc contains two devices, a bootloader, and the main firmware image.

If you are using windows, it is very possible that the driver for the bootloader specific device failed installation. Please check device manager, and look for the bootldr device.

If the bootloader is found, please try re-installing the graphical user interface. If that doesn't help, please try the following:

Manually installing the driver by specifying the location manually

If that doesn't work, then try using the freely available zadig tool with these instructions:

If the device is not found in device manager, please contact support by following this link:
