My TCL ROKU TV (65S405) has been stuck in version 9.00 Build 45. I have tried to update through the internet and found the version unchanged after reboot. I have then factory reset and connect to both wireless/cellphone hotspot, both returned to a fresh start and version still remains in 9.00. I then tried flash with USB and still to no avail. Now my ROKU TV is just a TV.
What's the issue? Is it software or hardware? What's your experience dealing with TCL in this regard? It's weekend and couldn't get through to the customer support.
