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?
Have you tried updating your H9 via USB using the Direct Updater on a PC or Mac?
