Bought the TCL-S355 about a month ago, working fine until this morning. Tried all suggestions about resetting tv, internet and checking connections to no avail. Contacted TCL customer support, nothing. I read one message saying that it's possible to manually update the box if you have the Roku model number which you cannot access while it is in this update loop. I would like a solution or will be returning it to Best Buy for a refund or exchange. Thanks.
