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.

After an additional update, the NTFS USB hard drive won't work anymore. I formatted it to FAT32 and that won't work either ( the TV wants to format it to be used as a DVR).

I would like to know if there is a code or something that will set the TV's firmware back to default.

Hello all,

I believe these steps will fix your issue:

1. Download the following files:

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

hi this even works for LA6600?

의 답변

No sure if this helps

LG TV

Press Menu

Press Settings

Scroll > Option > Factory reset (Yes)

reset to out of the box (yes)

This will reset the TV's settings, please do not play with the TV in the future.

Don't believe this will roll back the firmware. I believe the one I want to treat has some custom ROM flashed since it will not see the updates. Using the settings is important for any TV since the default picture has way too high a contrast but none of these settings will break the firmware!

I just upgraded the firmware for the 2014 smart TV to get the free view option, now the volume on the magic remote does not adjust the sonos sound bar when the TV is on (does control the sound bur when music is playing). I think they have disabled the optical volume control on that output, unless you use an LG compatible sound system. Any idea if it's safe to downgrade the software on a 2014 model yet? Not something I've ever attempted.

all of the TVs ranging from 2011 to present time perfectly rolled back.
