Updated the band for the latest firmware yesterday. This morning during listening to music was constantly crashing, freezing and restarting. And now band has died completely. Unable to turn on, unable to charge, black screen and nothing happening. I started to play music again and later I got a message on the phone, that fit 3 disconnected. But unable to do anything with it. Please, could you tell me, how it can be restarted and how the previous firmware can be uploaded to the Fit3, because the new firmware is a piece of *****.
