I am trying to upgrade to the Akira firmware and I keep getting "Handshaking Failed". I am connected via Bluetooth. The configurator app is showing "Connected" but I am getting no readings in the app. The Movi is unresponsive at the moment, basically hanging limp. The wireless light is the only light that is on. It is blinking, staying on for about 5 sec then off for 1. The three lights on the back are not on, even though it has a fresh battery. Updating on a Win10 Surface and Movi M15. Need help fast as we have a shoot in a few days. Thanks!
