Has anyone else had their ERX (newest version) front derailleur die from a firmware update? I was downloading/installing the firmware for the front derailleur and it cut out and subsequently killed my front derailleur. Nothing will revive the FD and I've tried absolutely everything under the sun to fix it. The app just shows "Front derailleur status is abnormal and cannot be used".
I'm at my wits end with trying to fix this.
