Gen 2 120a esc, the program card/box plugged into the esc via usb, the esc just says “esc disconnected” on the trackstar software.

Using a skylink usb connector it shows up straight away “esc connected”.

First time it showed up it came up firmware update, I updated it & gave me the option to roll back to earlier firmware.
Plugged it in the next day & the firmware rollback options were gone.
