I downloaded the firmware files but I can’t open them on my computer.
Your computer may consider the software to be a threat, as it is coming from an “unknown developer”. You may have to manually override the security settings on your computer. Please see the Download Instructions above for more details.
When I plug my device to the computer, I get an error message saying “the update software is not fit for this device”.
Each firmware file is specific to the device. This is a failsafe to ensure users do not inadvertently corrupt their device. If you see this message, double-check to make sure you downloaded the correct file. If you still get the error message, contact Interfit Support.
