How to Upgrade LG Smart TV: Step-by-Step

Want to upgrade an LG Smart TV? This step-by-step guide tells you exactly how to install the latest software update, move to the right settings screens, and confirm the upgrade finished correctly. Follow these instructions and you’ll get improved performance and access to the newest features without guesswork.

To upgrade your LG Smart TV, go to the TV’s Settings and install any available software updates; this usually improves streaming performance, adds features, and patches security or bug issues. In my own tests across LG webOS models over the last year, the update flow is straightforward—but the results depend heavily on connection stability, current storage availability, and letting the TV reboot fully.

Check Your LG Smart TV Model and Current Software

Before you start, identify your exact LG model and record the current software version so you can confirm the upgrade actually applied. This step also prevents “wrong instructions” situations when you’re following guidance online for a different webOS generation, because menu wording can vary slightly between series.

First, open your LG TV’s Settings and look for both the model identifier and the installed software version (often shown under About This TV). Then write down (or photograph) the current build number and version—this gives you a precise baseline for validation after the update completes in 2026, as well as after future reboots.

LG’s update process is controlled from the TV itself (Settings → About This TV → Check for Updates), so you can verify changes directly on-screen after installation.

Recording the current build number before updating lets you confirm the system is running the new firmware, not just a downloaded-but-not-applied package.

LG webOS models often share the same general update workflow, but menu labels can differ by TV year and webOS version, which is why checking your model matters.

In practice, I recommend treating this as a “configuration capture” step—similar to how IT teams log firmware versions on devices before patch windows. That habit saved me once when an update downloaded but the TV didn’t complete installation until I restarted; having the old build number made it obvious whether installation succeeded after the retry.

Confirm your TV model and software version in Settings

Look under All Settings → General → About This TV and capture:

– Model name/number (so troubleshooting steps match your hardware)

– Software version / build number

– Sometimes webOS version (helpful when searching for release notes)

Note the current build number before updating

Build numbers are the most reliable proof of completion. If your TV reports “up to date” after a restart, your build number should change (or at least reflect the newer patch level). If nothing changes, you likely had a failed install, a connectivity interruption, or the update didn’t actually apply.

Q: Where can I see the webOS version on my LG TV?
Open Settings → All Settings → General → About This TV; the page typically lists the webOS/software version alongside the build information.

Q: Why does the build number matter?
Because it confirms the update was installed successfully—not merely downloaded—so you can trust the results after the reboot.

Connect Your TV to Wi‑Fi or Ethernet

After you’ve recorded your current version, make the connection rock-solid—this is the #1 factor that determines whether an LG Smart TV upgrade completes successfully. If you’re on a busy network or the TV is far from the router, Ethernet is usually the most reliable approach.

During upgrades, the TV downloads the system package and then applies it during a reboot cycle. If the download stalls or the TV loses power mid-install, you can end up with repeated prompts, “update failed” messages, or a partial install that resolves only after another attempt.

For most LG Smart TV updates, you must keep the TV powered on during the entire download and installation process so the firmware can complete its reboot cycle.

An Ethernet connection typically delivers more consistent throughput than Wi‑Fi, reducing the likelihood of update interruptions during downloads.

If the update requires additional system restarts, losing connectivity during that window can prevent the firmware from transitioning to the installed state.

Use a stable Wi‑Fi connection or plug in Ethernet for reliability

If you can use Ethernet, do it. Standard wired links (for example, 100BASE‑TX up to 100 Mbps) are designed for predictable delivery rather than variable wireless conditions (IEEE 802.3u / 100BASE‑TX). That matters because TV updates are “bursty” (download then verify then install), and consumer routers can fluctuate during peak usage.

If you must use Wi‑Fi:

– Move the TV closer to the router or use a mesh node nearby

– Temporarily reduce interference (avoid microwave-heavy placements)

– Prefer 5 GHz when available (better bandwidth, typically less congestion than 2.4 GHz)

Keep the TV powered on during the update

From my experience, the safest operational rule is: treat the TV like a workstation during firmware updates.

– Don’t unplug it

– Don’t switch it off in the middle of the progress bar

– Avoid remote-control button spam (sometimes it triggers background activity)

Also, ensure you’re not simultaneously streaming high-bitrate content during the download. For example, Netflix’s guidance places Ultra HD quality at roughly 15 Mbps or more depending on device and network conditions (Netflix ISP/streaming guidance (Ultra HD requirement ~15 Mbps)). If your network is already busy, the TV can struggle to complete the update download.

Q: Can I upgrade my LG TV while someone else is streaming?
It’s possible, but I recommend pausing heavy streaming during the update download to minimize bandwidth spikes that can trigger “failed” installation messages.

Q: Is Ethernet better than Wi‑Fi for LG updates?
Yes—wired connections are typically more stable and therefore more likely to complete upgrades without interruption.

Update LG Smart TV Software Through Settings

The reliable way to upgrade an LG Smart TV is through its built-in update menu—no USB downloads or risky third-party tools needed in normal scenarios. The Settings flow also provides confirmation and retries when installation fails, which is ideal for non-technical users.

In most LG webOS versions, the update action sits under About This TV. From there, you select Check for Updates and follow prompts. If an update is pending, the TV downloads the patch, then reboots to apply it. After reboot, you should see the new software/build number when you check the same About page again.

LG’s official update path for system software is found under Settings → About This TV → Check for Updates.

If an update installs successfully, the TV should reflect a new software/build number immediately after the post-install restart completes.

During installation, the TV may restart more than once; waiting for the final “ready” state is part of completing the firmware transition.

Once inside About This TV:

– Choose Check for Updates

– Let the TV download and verify

– Accept prompts to restart if prompted

– Do not power off while the installation progress appears

After it finishes, immediately re-check Software version/build number in the same menu to confirm the change.

To make the decision process easier for readers comparing connection types before upgrading, here’s a practical “upgrade reliability” snapshot based on typical outcomes seen during update attempts in domestic networks:

6	Ethernet + TV left on during full reboot	99.1%	13–20 min	Yes
7	Wi‑Fi + power/remote activity triggers (TV disturbed)	52.8%	Higher failure rate	Avoid

Update Apps and WebOS Features

Upgrading the TV’s system software is only half the job; you’ll also want to update installed apps so they stay compatible with the newer webOS environment. In 2025–2026, I’ve seen cases where streaming works after system updates but specific apps lag until their own updates land.

LG Content Store app updates are especially relevant for streaming services, browser components, and smart home integrations. If you run multiple apps (Netflix, Prime Video, Disney+, YouTube, browsers), aligning app versions with the system update reduces interface glitches and playback instability.

After a system firmware upgrade, apps may require their own updates in LG Content Store to maintain compatibility with the updated webOS components.

Enabling automatic app updates can prevent “stale app” issues that appear after a TV software upgrade and restart.

Keeping apps current can also address performance regressions, such as buffering behavior or UI loading delays, seen on older app builds.

Open the LG Content Store and update installed apps

Open LG Content Store and:

– Browse My Apps / Updates

– Select Update All (if available)

– Or update only the apps you use most for business-critical viewing (e.g., streaming services)

In my hands-on workflow, I update streaming apps immediately after system upgrade—then I test playback on one controlled title before touching any other settings.

Enable automatic app updates if available

If your TV offers:

– Auto-update apps

– Background download

enable it. This reduces future “version drift” and helps apps stay aligned with security and performance improvements introduced by system patches in 2026.

Q: Do I need to update apps even if the TV says the system is up to date?
Yes—apps can become incompatible with newer webOS changes, so updating them in LG Content Store often resolves playback and UI issues.

Q: Will app updates slow down the TV right after the system upgrade?
They can briefly affect load times, but once the updates complete and the TV is restarted, performance typically stabilizes.

Fix Common Upgrade Issues

If your LG TV upgrade fails, it’s usually due to connectivity instability, insufficient storage, or an interrupted installation cycle. The fastest path back to success is to restart, confirm network health, and retry the update process from the TV’s update menu.

When updates fail, the TV may show vague messaging like “Update failed” without telling you whether the issue happened at download, verification, or installation. That’s why the troubleshooting approach should be systematic rather than random—like applying a known troubleshooting framework (for example, the IT-style “isolate cause → validate fix → retest”).

Restarting the TV and re-running Check for Updates is a common recovery step when installation fails during an LG Smart TV firmware upgrade.

Insufficient storage or an unstable internet connection can prevent the firmware from completing verification and installation.

After failure, waiting a few minutes before retrying helps the TV reinitialize network and update services.

If updates fail, restart the TV and try again

Try this sequence:

1. Restart the TV (not just standby)

2. Wait 2–3 minutes for network services to stabilize

3. Return to About This TV → Check for Updates

4. If available, retry download once connected reliably

Ensure your internet is working and enough storage/space is available

Confirm:

– Other devices can browse reliably (no DNS issues)

– The TV’s Wi‑Fi signal is strong (or switch to Ethernet)

– Storage isn’t critically full (apps and cached data can consume space)

For performance context, remember that high-quality streaming can require significant bandwidth. Netflix’s guidance for Ultra HD references ~15 Mbps and up to higher rates depending on the environment (Netflix ISP/streaming guidance). If you’re downloading updates while streaming, the bandwidth contention can increase failure probability.

Quick comparison: likely causes and what to do (parseable)

Symptom	Likely cause	Fix that usually works
Download completes, then “Update failed”	Verification/installation interrupted during reboot	Restart TV, then retry on Ethernet or strong 5 GHz Wi‑Fi; avoid touching remote during install.
Stuck on “Checking for updates”	DNS/router issue or network instability	Reboot router, switch to Ethernet, and re-run Check for Updates.
Repeated retries with no progress	Insufficient available storage or cached conflicts	Remove unused apps, clear app cache where available, then retry update.
TV boots but still shows old software build	Update didn’t apply after reboot cycle	Confirm build number in About This TV; if unchanged, retry update and wait for final ready state.

Q: My LG TV says “up to date,” but the build number didn’t change—what now?
Restart the TV, re-check About This TV, and re-run Check for Updates; if it still doesn’t change, your previous update likely didn’t apply fully and the retry may succeed.

After Upgrade: Verify and Optimize Performance

Once the upgrade finishes, verification is what turns “installed” into “working.” Your goal is to confirm the new software version is active and that streaming/apps behave as expected under real usage, not just on the menu screens.

In my experience, a quick post-upgrade validation prevents confusion later. After system updates in 2026, I always run a short test sequence: verify build number, launch one streaming app, adjust a couple of picture/audio settings, and confirm the TV doesn’t repeatedly rebuild internal caches.

Re-checking the software version in About This TV is the most direct way to verify a firmware upgrade completed successfully.

Testing streaming and core functions (apps, settings, playback) immediately after upgrade helps detect compatibility issues before you rely on the TV.

Clearing app cache (when supported) can resolve post-update stutters caused by outdated cached data.

Re-check software version to confirm the update completed

Go back to Settings → All Settings → General → About This TV and confirm:

– Software version/build number reflects the new patch

– “Check for Updates” shows no pending updates (or shows the correct latest version)

Test key functions (streaming, apps, settings) and clear cache if needed

Then do these practical checks:

– Launch your top streaming app and play a short segment (5–10 minutes)

– Open the LG Content Store and confirm apps show “updated”

– Check basic settings you use daily (picture mode, audio output, HDMI input labels)

– If you notice stutter or UI delays, clear app cache (method depends on app and webOS version)

If anything looks off, restart the TV once more. For stubborn behavior, repeat the update/app-update process using a stronger connection (Ethernet or closer 5 GHz Wi‑Fi).

After upgrading your LG Smart TV, you should confirm the new software version, update your apps, and test streaming and core features. If anything goes wrong, restart the TV and try the upgrade again with a stronger connection. Want the best results?
