I have UE40H6670 tv
I have firmware T-MST14DEUC-2740.6
How to come back 2130.0 firmware.. Please help

Sorry, there's no going back. Samsung prevents downgrading.

Jtag ?

WARNING!!! Looks like on some routers it is NOT possible to block firmware updates. For example on DD-WRT you have this:

TV should report "Failed to connect" if blocking on router was successful!!!! If blocking worked you should NOT be able to load this page:
Router blocking test page

Fritzbox no Problem

Seems to work

With blocking:
Without blocking
Using URL filter on RT-AC66U MerlinWRT

If my test "works" for you should be safe to try updating TV over the network it should say "failed to connect" or something similar

Will report later this week on non rooted T-MST14DEUC-2135.4

Don't know if this info is useful:

Just checked today two UE40H6640 tvs from relatives. One has T-MST14DEUC-2135.4 with OTA / OTN disabled. No option to block in router. But tv says no upgrade avaible when trying to update.

Second UE40H6640 has T-MST14DEUC-2604.1 with OTA / OTN disabled. Blocked the 4 links in router. Will report if this will update

Hi there,

I just want to let you know that disabling OTN on T-MST14DEUC-2740.6 worked, it was not greyed out.

HOW about a screenshot of your routers "access restrictions" page? preferably where it says "blocking by url"
