You've done everything I'd think to do. What's odd is that the FD is the brain of the system and sends commands on to the RD, so if there was am issue with the FD I'd expect it to affect both.
You able to warranty it?
** last thought. Have you tried swapping the batteries over?
Thanks but I've tried swapping the batteries and it's the same. It'll soon be on its way back to Germany. Hopefully BD will replace it. Trying out Etap 1x in the meantime...
Is the FD really the brains? One of the benefits is that if the RD battery runs out of power you can simply swap the batteries over and it allows you to still shift on the RD, presumably whilst the FD is dead.
Yep, rear is working perfectly. Tried pairing it again. Changed batteries. Same thing. Dunno what else to do. I see no reboot button :(
