Forget the Bluetooth update, it has never worked!
Try it via USB-cable.
Every time I try to upgrade my H9 max to the latest firmware I get a communication error (see photo). I’ve factory reset the unit twice and the same message appears. I’ve tried upgrading from two diff phones as well :-/ any idea what’s going on?
