Hi folks, I received my gbc 8-bit boards which was in 2.2b2, and only automatic roll was working. No action on pitch despite of correct wire connection...
I decided to upgrade with the latest firmware 2.40b8. My baaad! I tried through GUI (flash failed), and XLoader and AvrdudeR... I believed it was failed as well, but when I connect it using GUI, something changed: it's stuck to 'Connecting ...'
I understood(too late that I would have used the GUI 2.2b2 instead of flashing a bad version. That's why I would like to know how to do a factory reset or something like that, because my gimbal is bricked for now...
