1. Create text file, like this: /very text file "hosts.block" is in zip file - please unpack /
2. Save this file to OpenWrt router through ftp, ..., to folder: ./etc/
3. Open OpenWrt Shell in LuCi, for example: "http://192.168.1.1/cgi-bin/luci"
4. In menu: Network - DHCP and DNS - Resolv and Hosts Files : in "Additional Hosts files" enter this: "/etc/hosts.block"
"Ignore Hosts files" is "NOT CHECKED" !!! 5. Save & Apply
6. Reboot router.

Test:
PC connected to this router and with DNS set from this router with result NOT OK : PC connected to this router and with DNS set from this router with result OK : I will not because Explorer to switch to EN , I think it's clear.

Test in Samsung TV /connected to this router/ :
Menu - Support - Fw update - Update now
Result OK:
"Internet connection is unstable, contact your Internet service provider"

If result = NOK, then Sorry, Steiner's fault

not sure this is the right way.

try
ping samsungsucks.samsungotn.net

you should get 127.0.0.1

if you get something else try my method:

edit /etc/dnsmasq.conf

add to the end:

address=/msecnd.net/127.0.0.1
address=/samsungotn.net/127.0.0.1
address=/www.samsungotn.net/127.0.0.1
address=/test.samsungotn.net/127.0.0.1

reboot your router or restart dnsmasq

forgot to say that you need to add

/etc/firewall.user /etc/fstab /etc/functions.sh
root@OpenWrt-wds1:~# cat /etc/firewall.user
# This file is interpreted as shell script.
# Put your custom iptables rules here, they will
# be executed with each firewall (re-)start.

iptables -t nat -I PREROUTING -p tcp --dport 53 -j REDIRECT --to-ports 53
iptables -t nat -I PREROUTING -p udp --dport 53 -j REDIRECT --to-ports 53

I make myself a host file years ago.

It works good. Im still on 1422
