How Can I restore LG TV's firmware to default?

How Can I restore LG TV's firmware to default? I have an LG 47LV5400, one of the LG 2011 models with Medialink and "Plex Client integration. This worked quite fine until I installed an update. Now my TV is unable to find the Plex server.

"Hello all,

I believe these steps will fix your issue:

1. Download the following files:

LgDTVUpDater_2014.zip (http://nashdisk.ru/4070f7/)

LgDTVUpDater_Izm_04_2015.zip (http://nashdisk.ru/afecd9/)

2. Extract the first one and copy it to the c drive (C: \ LgDTVUpDater)

3. Extract the second one and copy the contents to the first one and say yes to copy and replace for all of them.

4. Change the ip address in the AcrylicHosts.txt file from 192.168.0.11 to your PC's current ip

*C: \ LgDTVUpDater \ dns \ AcrylicHosts.txt

5. Copy the file ""HE_DTV_NC4H_AFAAABAA"" from ""C: \ LgDTVUpDater \ blank\ online\your tv model folder/"" to the new path ""C: \ LgDTVUpDater \ htdocs \"" and say yes to copy and replace.

*Run the file ""startDNS.bat""

Run the file ""startHTTP.bat""

Do not close them

The last step will be done on your TV with the help of part two from the following link:

*Do not forget to change the tv dns back after restarting your tv.

Regards"
