My android tv is stuck on upgrading. When I start tv, it shows samsung logo, then few seconds of android is upgrading app and then it shuts down automatically. I'm not able to reach settings option or even hard reset option by pushing (mute+1+8+2+power) buttons on remote. No matter what I press, it stays on the same upgrading android screen for few seconds and shuts down. It doesn't do anything else. Does anyone has any suggestion? What can I do to fix this problem?
