I updated my 49SJ800V TV's firmware from 04.70.95 to 05.80.15 and my smart remote controller not working properly. I can't use cursor and back button also i have connection problem with LAN and WLAN. I use my tv with cable connection but every 15 minutes LAN disconnecting and try to connect again. I resetted my tv to factory settings but result is same. I can't use my tv now normally. how can i downgrade my tv's to last working firmware. I couldn' t find old firmware. Could you help me to downgrade my tv' s FW ?

I have the same exact issue since the last update, i tried to contact with support but they told me that i should send it to local LG service. Its obviously a firmware issue and there is no way to downgrade, my tv is literally not useable right now. 49SJ800V on 05.80.15 fw version. I found a fix by myself but its temporary. If you disable Wi-Fi or Ethernet the problem goes away but you can't use any of the online features. Hope they fix this ASAP.

I’m sorry to say this, but I’m glad that I’m not the only one with this problem. I have a 43UH650V, with 05.30.45 software version. First it started with a weird error message preventing to start Netflix. So had no other option than resetting my TV. Netflix uninstall reinstall didn’t help by the way. After resetting the TV first noticed that I can’t accept the User Agreements because it doesn’t load. Tried everything what I could find possible solutions on different forums. • Changing location and language. • Changing DNS to Google DNS IP address. • Using a mobile hotspot. • Disconnecting everything from the TV, reset. • Disconnect from power for 24 hr. Non of the above helped. interestingly, when the TV starts up now instead of software version I see ##.##.## for long minutes. Automatic time and date setting doesn’t work either. If I unselect Set Automatically option, it show 1:00 Friday 1 January 2016, doesn’t show the current time. I think this was the original problem with Netflix, the TV didn’t set the date and time automatically. Tomorrow I will try to call support, weekdays is not possible for me, as their opening hours are the same as my work hours too. I have no idea what else to do with a TV now, shame because I was a huge fan of LG TV and webOS too.

Good luck with all the time wasted looking for an answer, but whomever said, unplug your tv, anything hooked up to it, and unplug your router should be highly rewarded with a big bag o’ cash. This worked for me. I did every option except changing the dns - that looked too scary, I did re-set, went to every available thing available. Use my phone as a hot spot? Come on? Lg is supposed to be the best and this is something someone had to figure out as an option? Very disappointed with my new tv not being smartly, and I was too stupid to know how to agree to a user agreement, was making me think I actually had to hire someone to figure this out. I am in a learning curve with this, and the smart tv scenario is really defeating, but unplug, wait and find your user agreement and agree to them! Netflix marathon is happening.

copy / paste from my reply on the firmware topic : ever since i updated to the last fw, my tv turned into a total piece of trash , although it was not working so well before the update but after that, it is completely useless i can tell you . wondering how much longer we have to wait for a real fix ... been facing this issue since may 2018 and it get worse and worse with any new update ... plz fully test fw before u turn our tvs into a useless pos . 49sj800v .

Having the exact same issue with the magic remote on my 49uj7500, same firmware. It's so annoying. Tried everything but could not downgrade. Magic remote comes and goes randomly.
