What a red flashing light on your VICTORY smart trainer means.
If your VICTORY LED is flashing RED, this means that during the unloading of the firmware the connection has been interrupted somehow. Your trainer now has lost calibration and will need a special firmware to re install.
Please email support@jetblackcycling.com with your trainer serial number and we will come back to you with instructions. FYI it will take our engineers a couple of hours to build this specific firmware for your trainer.
