Hi @BeeTun,
Thanks for the first post to the Roku Community!
We appreciate you letting us know about your trouble with your TCL Roku TV, which will not activate after a factory reset with a link error. ACTIONID: 0 err:0:0.
In this case, we recommend restarting your modem/router, even if other devices on the network are not having problems. When your router has completed its startup, try repeating your Roku setup.
Additionally, you can try using a different WiFi network to do the update—perhaps via a WiFi hotspot on your mobile phone or by taking it to a friend's house—and see if it will complete the startup. If successful, redo the WiFi connection to use your intended WiFi network via Settings > Network > Set up connection.
Please keep us posted on what you find out, and we'll continue assisting you from there.
All the best,
Chel
