Have explored most of the available LG webos firmware downgrade instructions but found  nothing that addresses downgrades of 4.2 Android upgraded Google TV G3 series GA6400.

Trying to find a firmware downgrade, upgrade, or anything that will give me back the use of the coax/TV port so i can conect to an OTA antenna.

      Have a good time! I have such a problem. The OLED42C3RLA TV Accidentally installed the engineering firmware 66.66.ff (99.99.00.01) How do I return the official firmware?

      Hello,
      I have a problem with my new LG OLED G2 newest version 4 firmware.
      I tried sorting my satellite channels with chansort programm from github, because sorting them with the tv remote is a pain.
      When I try to sort them with the remote and have selected about 10 or more channels all the selected channels get suddenly getting deselected, so I can only select up to 10 at a time  to 
      sort them -> must be some kind of firmwarebug? 
      After exporting the channellist to a usb stick then editing it with chansort an importing it back into the tv all my channels are gone, all transponderns are deleted.
      First I thought it was a charsort problem but all channels and transponders get also deleted when I simply export them to a usb drive an import them back, without editing the file at all.
      Does someone know how to fix this problem? 
      And yes I´ve done multiple factory resets -> did not fix any of this behaviour.
      I also discoverd another bug the deletes all channels, because I needed to reboot the tv I searched for a reboot option in the tvs menu, but there is no reboot option.
      To do a full reboot (except from forcing it through cutting the tvs power) you can deselect the privicy agreements, after that the tv reboots, but then all channels are gone too.
