Mine started this yesterday 10/25, Westinghouse Roku TV. I did multiple resets, unplugged it for almost 24 hours, tried the update with the USB and no internet connection and its now been stuck in a continuous reboot loop for close to an hour. It gets me to the "Please don't turn your tv off" right after it says it updated and then just runs through continuous off and on and the Roku TV pops up on the screen then shuts off and right back to it. I don't even have this tv 4 years. Tried the reset button, power reset, factory reset, recovery mode, setting the tv up without internet and connecting from the settings menu and NOTHING IS WORKING
