TCL 55S401 Roku site Model number?

I have a TCL Roku TV stuck in a boot loop. I tried all the available reset methods, and none have revived the TV. It shows the red TCL Roku screen for a while, then goes black and comes on and repeats over and over. 

I want to direct flash the firmware if I can, but the first step is providing a model number other than the 55S401 printed on the back of the TV. I need a number only found in the TV settings. This is impossible since the TV will not work correctly enough for me to retrieve this information. 

I reached out to TCL to see if they could provide the information based on the serial number, and they could not. 

I get to this site (https://tvupdate.roku.com/index?p=select) to see if I can get the firmware to flash, but it rejects 55S401 as a model number. 

Service No.: 55S401LDAA

Model: 55S401

I like the TV and would love to revive it. It is too cheap to have repaired, so this is a last-ditch effort before it goes in a land fill. Sad. Is there another use for the panel? Is there a way to jump it right to an HDMI input bypassing the Roku? I really would hate to throw it away.

      That worked. Thank you. 

      This file on a USB stick requires the TV to function normally, though. Is there a way to force the update, like installing a ROM on a cell phone?

        I was afraid it wouldn't automatically recognize it.  I saw other people post that they needed to disconnect all external devices, so if you haven't already, give that a try.

        If holding in the reset button for 30+ seconds doesn't change things then it's probably time for something more drastic like searching for a compatible main board on ebay and giving it a shot.  Other than that selling the parts or the whole thing to someone else that may want to try fixing it is probably the only way to recoup some money.
