Firware downgrade On UE40EH6030

[Markeu]

Before dumping my tv into the street i would like to ask for help

Since my tv did an update to firmware 1017 is no longer HD ( on xbox it shows that he uses 640x480 resolution) and also does not work with the old CI from the cable guy ( he was here scratched his head and left)
I honestly tried to install Samygo .but to no succes i guess my tv is not that smart or me .I just want an old firmware that will make my tv back to the good old days like a 1016 if it is any OR any simple stuff to do to revert.


soory for my poor english im just mad.

Manny thanks and God bless

ok looks like the only answer will be to replace the main board because they dont do down grade of firmware in the Samsung service here.

Also no known way to downgrade firmware on your TV model here, sorry.
