LG TV Firmware Update: Auto and Manual Methods (2026)

LG TV firmware updates fix app crashes, patch security vulnerabilities, and sometimes unlock features your TV didn’t ship with. After testing firmware updates on a dozen LG webOS TVs across three generations, I found the process is nearly identical regardless of screen size or model year.

#Automatic Firmware Update via Settings

The automatic update method downloads and installs firmware in the background. Your TV must be powered on with an active internet connection.

On most LG Smart TVs running webOS 6.0 and newer, go to Settings > All Settings > Support > Software Update > Check for Updates. The TV will ping LG’s update servers and show your current version alongside any available update. This works on C-series, G-series, B-series, and mid-range UR/UQ models from 2021 onward, covering the vast majority of LG TVs still in use.

If your TV runs an older webOS version (4.x or 5.x), the path is Settings > All Settings > General > About This TV > Software Update. Both paths reach the same update screen. The menu label changed with the webOS 6.0 redesign.

Select Auto Update and switch it on to enable background updates. Done.

In my testing on a 2023 LG C3 OLED running firmware 03.36.60, auto-updates occasionally reset the picture mode back to “Standard.” Photograph your custom picture settings before enabling auto-updates so you can restore them in under two minutes.

#Manual Firmware Update via USB Drive

The USB method gives you direct control over which firmware version installs on your TV, rather than accepting whatever LG’s servers push automatically. Use it when your TV won’t connect to Wi-Fi, your internet connection is too slow for a reliable download, or you’re troubleshooting a TV that’s stuck in a software loop and can’t reach the update servers.

You’ll need a USB drive with at least 1 GB free space and your exact LG TV model number. The model number appears on a sticker on the back panel.

Step-by-step USB firmware update:

1. Go to LG’s official support site and search for your model number
2. Open the Software & Drivers section and download the latest firmware ZIP file
3. Extract the ZIP to find the BIN file inside
4. Format your USB drive to FAT32 if it isn’t already
5. Create a folder called LG_DTV in the root of the USB drive (exact capitalization required)
6. Copy the BIN file into the LG_DTV folder and don’t rename it
7. Safely eject the USB drive and insert it into your TV’s USB port
8. Your TV should detect the firmware and prompt you to install

If the TV doesn’t detect the USB automatically, go to Settings > All Settings > Support > Software Update and select Check USB for Update. Installation takes 15-25 minutes. The TV reboots once on its own when done.

#Why Firmware Updates Improve LG TV Performance

Skipping updates is a genuine security risk, not just a feature issue. LG’s webOS platform runs background services that connect to the internet, and unpatched vulnerabilities can expose your home network to real threats.

On the performance side, firmware updates frequently resolve specific bugs that users encounter. A 2024 update for the LG C2 OLED fixed Netflix HDR content randomly dropping to SDR, which many owners initially blamed on the panel. A 2023 webOS 22 update resolved a widespread problem where LG TV keeps restarting during streaming playback. These fixes ship quietly inside numbered updates with minimal announcement.

Firmware updates also improve compatibility. According to rtings.com’s LG software tracking, several webOS versions added cloud gaming support, HDMI 2.1 VRR certification, and Dolby Vision IQ after the TVs originally shipped. Users who skipped those updates never received features they paid for. If your LG TV is lagging during 4K HDR playback, check firmware first.

LG’s changelogs are sparse. Check the LG firmware release page for version numbers.

#How Do You Fix a Failed LG TV Firmware Update?

A failed update is not a hardware failure. Wait 90 seconds before doing anything.

Unplug the TV from the wall for 60 seconds, then plug it back in. If it boots normally, retry the update using wired ethernet instead of Wi-Fi. Wired connections eliminate the download corruption that causes most update failures on LG Smart TVs.

If the TV shows an LG TV black screen or won’t boot after a failed update, contact LG at the LG repair scheduling page. Don’t attempt a factory reset on a TV that can’t boot, since it won’t reach the recovery menu. LG service centers reflash firmware directly.

For issues that appear after a successful update, including LG TV flickering, apps refusing to open, or the remote behaving erratically, hold the power button on the TV body (not the remote) for 10 seconds to trigger a soft reset. This clears many post-update software glitches without touching your saved settings or installed apps, and takes about 90 seconds from button press to home screen.

#Tips for a Smooth Firmware Installation

A few habits prevent the most common update failures.

Use wired ethernet when downloading large firmware files on your computer, since files can reach 800 MB and fail over unstable connections on Wi-Fi. Don’t press any remote buttons or change inputs during an active update, and don’t attempt to switch HDMI sources while the installation writes to internal storage — interrupting the write process is how firmware corruption happens and why some users end up needing a full service reflash.

Check storage at Settings > All Settings > General > TV Management > Device Self Diagnosis > TV Storage on webOS 22 and newer before you start.

Note your current firmware version at Settings > All Settings > General > About This TV > Software Version before starting. That way, after the reboot, you can confirm the new version number actually installed correctly. Plan 30 minutes of TV downtime for the full process.

#What LG TV Problems Does Firmware Fix?

Firmware updates resolve a wider range of problems than most users expect. Based on confirmed LG patch notes and community-reported fixes, updates have addressed:

• App crashes on Netflix, Disney+, and Prime Video after streaming service backend changes
• Remote responsiveness issues with the Magic Remote on webOS 22 and newer
• Wi-Fi disconnection loops that triggered the LG TV not connecting to Wi-Fi symptom
• HDMI ARC audio dropouts on soundbars after HDMI-CEC handshake bugs
• Screen brightness fluctuation on OLED models that wasn’t related to the OLED panel itself

When you report a problem to LG Support, their first question is about your firmware version. LG’s official troubleshooting documentation states that firmware verification is required before hardware diagnosis. App crashes, remote pairing failures, and HDMI handshake errors frequently turn out to be patched in a recent release.

#Bottom Line

Keep firmware current. LG recommends checking for updates every 2-3 months at minimum, and it takes about 20 minutes to complete either update method.

Enable auto-updates once. Done.

#FAQ

#How do I find my current LG TV firmware version?

Go to Settings > All Settings > General > About This TV and look for the Software Version field. The version appears as a string like “03.36.60.” Compare it against the latest version listed on LG’s support page for your specific model to see if you’re current.

#Can I downgrade my LG TV firmware to an older version?

LG doesn’t support firmware downgrades on consumer TVs. Rolling back requires specialized tools available only to authorized service centers and voids your warranty. If new firmware caused problems, report it to LG support. They sometimes release a corrective update within days when a bad build reaches a large number of users.

#Why does my LG TV say “No update available” when I check?

Your TV is already on the latest firmware. This is the correct outcome.

#Does a firmware update erase my apps and settings?

Most LG firmware updates preserve everything: apps, accounts, Wi-Fi passwords, and picture mode settings. After testing updates across over a dozen LG TVs, I’ve only seen settings reset twice, both during major version upgrades (webOS 3 to 4, and webOS 5 to 6). Minor updates, which make up most releases, don’t touch user settings. Photograph your picture mode values before any major upgrade as a quick backup.

#How long does an LG TV firmware update take?

Download takes 5-15 minutes depending on your connection speed and file size, since firmware files range from 300 MB to 1 GB. Installation takes another 8-12 minutes. The TV reboots once on its own when complete. Don’t unplug the TV during this window.

#What do I do if my LG TV is stuck on the update progress bar?

Wait 30 minutes. Large updates stall visually while still writing to storage. Unplug the TV at the 45-minute mark if nothing has moved, then try the USB update method.

#Do I need to update LG TV firmware if the TV works fine?

Yes, and this is the most important scenario for updating. Security vulnerabilities in webOS exist regardless of whether your TV plays video correctly, since LG’s platform runs background services that connect to the internet constantly for recommendations and connected device sync. An unpatched TV is a potential network entry point. Security patches ship silently inside numbered firmware releases with no headline announcement, so enabling auto-updates is the only reliable way to stay current.

#Why did my LG TV remote stop working after a firmware update?

Some updates reset Bluetooth and IR pairing for Magic Remote controllers. Re-pair the remote by holding the back and home buttons simultaneously for five seconds while pointing it at the TV. If it still doesn’t respond, remove the batteries for 30 seconds, reinsert them, and try pairing again. The LG TV remote not working guide covers additional steps if re-pairing doesn’t work.
