LG UF//"V-ZP - How to update from USB

Recommended Posts



First post!


LG 65UF772V-ZP


Menu on the TV, doesnt search proberly on the SW..menu say"cant cant get any update!"


Ive tried to connect the internet from cabel or wifi, doesnt matter!


So, have DL the SW from LG's online site and get a version number: 4.21.00..TV runs 4.00.70 now


Make a map on USB named "LG_DTV"and tried to connect to port 1.2.3..but the TV doesnt promt any screen, so what should i do now?


Is there any "USB service port?"


Any hints?


Best regards
