Updating Firmware - TV

Repair TVs Last Updated 03/28/2017
Updating Firmware - TV

Firmware updates are released on an as-needed basis for Smart TVs. These updates are used to enhance current features, fix bugs, and in some cases add additional applications to the device.


Note: An Internet connection is required to perform a firmware update. If you do not have Internet available on the TV, you may need to perform a Manual Firmware Update.

How to Check Automatic Updates

Press the Home/Smart  button on your remote to bring up your launcher bar.

Click the Settings icon in the top-right.

Choose the All Settings option at the bottom.

Choose the General menu from the left.

Scroll down, near the bottom of the list, and select About this TV.

From here, make sure Allow automatic updates is checked, and click the Check for updates button.

If an update is found, follow the steps on screen to download and install it.

Back Next Home

Press the Home/Smart  button on your remote. From the Home Screen, choose Settings from the bottom-left.

From the Settings menu, navigate to the Others tab in the bottom-left, then choose Software Update to open the update options screen.

This screen will display your Current Software Version, and provide some additional Software Update related options (explained over the next few slides).

Turn Software Update on or off. If set to Off, Software Updating will be disabled, and you will not receive update notifications. To proceed, set this to On.

Check this box to allow your Smart TV to automatically check for, download, and install software updates. If left unchecked (with Software Update set to On), you will be notified when an update is available, but will have to manually complete the process.

Click the Check Update Version button to manually perform the check.

If an update is available for your TV, you will see the following notification. Click the Update button to start.

You may choose to Hide the update progress screen if you'd like to continue using your TV during the update. Press the Info button on your remote at any time to view the progress.

Note: This process may take some time and will need to be plugged in and powered on until it's complete.

Firmware can be updated manually by downloading the update file from lg.com and placing it on a USB storage device.

To perform the update, you'll need:

  • A USB flash drive with at least the size of the firmware update of available storage(check the file size on your product support page).

  • A Computer with Internet access.

  1. Find your Product Support Page

    You can find the firmware file for your tv on the Product Support Page for your model.

    1. Visit the Support Home Page.

    2. Enter your model number into the search box.

    3. Click your model from the predictive drop-down list that appears below the search box (as you type).

  2. Download and unzip the file

    From your Product Support Page, download the latest firmware file.

    When it finishes downloading:

    1. Open your Downloads folder (or the folder where the zip file downloaded to).

    2. Right-click on the zip file's name, then choose Extract All... from the menu.

    3. When the extraction dialog opens, you can leave all of the deafult settings and click Extract.

  3. Put the file on the USB

    On the root of the USB drive, create a folder named LG_DTV.

    Important: The folder must be named exactly as shown above. The tv will look for only this specific folder when searching for updates.

    Place the unzipped file into the LG_DTV folder. The file type should be EPK.

  4. Insert the USB

    Turn on the tv first, then insert the USB drive that you have prepared.

    Follow the instructions on the tv.

Note: The tv is very particular. If you are having trouble, make sure the firmware file that you're using is made for your TV, and make sure the folder on your USB drive is setup properly.

    • Some updates are large and can take time to download, especially over slower Internet connections. If the percentage is increasing, please let it continue.

    • If the percentage is not increasing, ensure the TV is within range of the wireless router with minimal obstacles between.

      Note: The wireless receiver built in to the TV may not be as strong as other devices.

    • If the screen says Downloading, Restart the TV and wireless router (unplug them then plug them back in).

    • If the screen says Updating, do not unplug it!

    • If the issue persists, Contact Us.
