I can not downgrade firmware.
I do everything according to instructions viewtopic.php?f=22&t=4199 but the TV still says that the update has been found for my machine.
TV connected to the Internet through a router.
DNS on TV 46.4.199.222
but why did not roll back? Please help me.
In any case, post the screenshots of the settings OTN
And a screenshot of the brain tv
