1. Just format a USB falsh drive in FAT32.

2. Create a folder named: LG_DTV

3. Copy the firmware file inside the folder LG_DTV

4. Insert the USB on TV

5. Press install

6. Check on TV settings, general, about TV. You will see the firmware being installed, just like normal download over the internet.

7. When finished, turn off the TV and then turn it back on.

Thank you very much! I installed that version (05.00.55) in my 50LB6500 (I'm from El Salvador, but I don't know what's the tv region).

I've had my tv on for a couple of hours and so far everything looks good. I'll post another update after more hours of use.

Just installed the version 05.00.55 (corrected, not .50) from that link and it seems to be solved! My TV: LG WebOS 42LB6500. I think this firmware is multi language, since I can choose the language and region on settings. Maybe you guys can give it a try! Hope it helps!

How did you install it?

Hey guys! I've found a post on a forum here in Brazil. A lot of people are experiecing the same issue. It is a firmware (05.00.35) issue. The new 05.00.50 solves it. Here is the link for the new firmware for manual instalation. At least for my 42LB6500 Brazilian TV: http://su.lge.com/GlobalSWDownloadCdn.laf?IMG=/201512/starfish-atsc-secured-m14tv-25.ashley.m14tv-2515-05.00.55-prodkey_nsu_V3_SECURED.epk

Thanks! Hopefuly I can find the new version for my tv.

I was about to send for repair, because it is out of warranty. Now I'll wait if there are any solution, since other people are experiencing the same problem. I've also tough of downgrading the firmware, will try. Thanks!

If you find a way to downgrade the tv software, please let me know how.

Exactly this is happening to me. I upgraded the firmware of the theater but didn't solve the issue. I thougth of dowgrading the tv webos software to the previous version, but haven't found a way to do it

I have another model, but I just upgrade the firmware. Hopefuly this solves the issue.

Thanks @Jecamacho, I'll check it out

Hi all,

I have a 50LB6500-SF and I have an LG home theater connected using the optical port. I configured this with Simplink, So I can control the home theater with my tv magic remote control. In the audio setting I have the Audio Output as Optical, and it has been working great until last update. Now almost every hour, the Audio output changes to the TV Speakers by itself. So I have to go the audio out setting and changing it back to the Optical port, but then after a while it changes back to the TV Speakers and it's really annoying. I haven't changed anything, that's why I think is a bug that came with this update. Does anyone have this issue? Any idea of how to solve it? I tried removing and adding the home theater, but didn't fix the issue.

here are the more details about the tv:

LG 50LB6500-SF

Software version 05.00.45
webOS TV version 1.4.0-2513 (afro-ashley)

Thanks in advance!!!
