Hi . 6200 won't turn fully on. Gets to a screen which shows a broken connection (x) between device and computer. When I try to connect its begins to restore but switches off after about 10% and starts all over again. Cant get the 6200 to go to the white text for a factory reset. not sure what to do next.. Also the device doesn't show on my connect account, but I can't add t as it won't connect to the PC (Mac). Bought new July 2018. Any thoughts anyone??
