I have an Oled CX series. My webOS Ver is: 5.2.1-290906 (jhericurl-jardine).
The TV has software ver: 03.21.18. I downloaded the software from the LG site, and copied to a USB stick. Next I tried in eirher port, but the only options are what I usually see, (1) Photo/Video or (2) Music. It's not like what the LG web page shows for using a USB drive.
But, since it appears I have the latest software
How did you get WebOS 6.x, and what series TV do you have?
I've only had mine a little while so I'm not all that familiar with everything yet...
Thanks!
