LG don't appear to have the user agreements working for all countries, which is ridiculous but there you go. In my case, it was South Africa. I had to manually switch the country to Saudi Arabia on the LG device in the location setting (which caused a reboot), then go to the LG website on my PC and register a username with the country as Saudi Arabia, then back to the LG device (now booted up again) and choose the agreement option in the menu, then use the newly created username to sign the agreement(s). I connected the LG device to my mobile hotspot for all of this, then switched it back to the usual wifi router afterwards.
