You have lost your original remote and got into this by pressing info select and the option 7 UART Download. Happened to my 95 year old aunt in assisted living. You will need the original remote and simply hit (EXIT) or another LG branded remote that has the (ROUND RETURN BUTTON) on the left. Once you accidently get in to this, I have not found a universal Zenith remote that can get you out even though Channel up/down and basic funtions work.Bud retired Bud's TV Service.
If you notice it tells you at the bottom of the message to hit Exit. I am not saying another universal remote won't work for you ,but once in this state you cannot program it to the set for the set will not respond. When you apply power it will be on with the message TV Software Upgrade as described. When you hit EXIT the snow will return if you have the antenna disconnected and everythig is back to normal. With the original remote you can't get int this mode accidently.

What if u don't have the orignal remote cause it got broken
This worked: Logitech remote programmed with the computer. Hit Exit. Problem solved.Will NOT work if you CAN NOT hook up the Universal remote to PC and PREPROGRAM it FIRST. If you use a remote that requires you to test the code on the TV to make sure it will work, it wont. No need to update software or replace motherboard. Used Logitech Harmony 550 remote to fix my problem. I am sure any Logitech remote will work with it as long as you program it on the PC using the USB cable and the software on your computer. Glad to help!
