My Roku Ultra LT is stuck in a reboot cycle. I did the 30 second reset to get it back to factory defaults and started configuring it again. During this process it rebooted itself 2 times without completing the setup and went back to the bouncing Roku but fails to go past that. I tried another factory reset again after this, but all it does is stay at the bouncing Roku now. There is no card in the SD slot. I bought this during Thanksgiving week this year (2020) from WalMart so it’s a new device. HELP!
