I've purchased a VESC 6 75V and it came with beta firmware 6.0 (status beta 56). The VESC software complains that I have to downgrade the firmware or upgrade the VESC software. Since there's no newer version of the software available, I need to downgrade the firmware. When I go to the firmware page, it shows all available versions as long as I don't connect to the VESC. But in order to download the firmware, I must first connect to the VESC, but as soon as I do that the list with available versions is cleared. So it looks like I'm not able to downgrade the firmware or upgrade the software.
What am I supposed to do now?
