49SJ800V Firmware Update Problem

[Blackstone]

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 ?

 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.

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 .

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.

same issue wifi and remote control stop responding randomly since 05.80.15, model 43uj750v.

the TV is now unusable outside manual control located on the bottom of the screen.

revert to factory settings didn't help much, after a couple of days the TV become unusable again.

LG software Q&A is disgusting.

I called the LG local service and made a servise request. When they came home they only opened the back of the television and clean and fixed the sockets. It means there was a socket cable that was wrapped. They opened it and flattened it. My problem resolved my TV is working properly and they didn't make any FW downgrade. My firmvire version is 05.80.15 Ithink you need to call your local LG service and tell them my story 🙂
