LG TV Error 125 — What It Means & How to Fix It

What Does This Error Mean?

Error 125 on an LG Smart TV means an app failed to download or install its update from the LG Content Store. This is usually caused by a temporary server issue, insufficient storage on the TV, or a network interruption during the update. Retrying the update after a router restart resolves Error 125 in most cases.

Affected Models

LG OLED C3
LG QNED85
LG UHD 75UP8770
LG NanoCell 90
LG OLED evo G3

Common Causes

LG Content Store server had a temporary error while delivering the update package
Network connection dropped mid-download, leaving the update incomplete
Insufficient storage space on the TV for the updated app version
The app update package is corrupted on LG's server (usually resolved within hours)
TV firmware is too outdated to support the new version of the app

How to Fix It

Wait 30 minutes and retry the app update from the LG Content Store.

Error 125 is often caused by a momentary LG server issue — simply retrying after a short wait resolves it in many cases.
Restart your router by unplugging it for 30 seconds, then retry the update.

A brief network interruption during the previous update attempt may have caused corruption — a fresh connection gives the download a clean start.
Power cycle the TV by unplugging it from the wall for 60 seconds, then restart it.

This clears any partially downloaded update files that are blocking the new update attempt.
Check available storage: Settings → General → About This TV → Storage and free up space if it is nearly full.

LG Smart TVs have limited internal storage — if it is full, app updates cannot be installed and Error 125 will keep appearing.
Delete the app showing Error 125 and reinstall it fresh from the LG Content Store.

A fresh install downloads the current version cleanly without inheriting the broken update state.
Update the TV firmware: Settings → Support → Software Update → Check for Updates.

Some app updates require a minimum firmware version — updating the TV OS ensures all apps can install their latest versions.

When to Call a Professional

Error 125 is a software update issue — no professional repair is needed. All fixes involve retrying the update, clearing app data, or freeing storage space. If Error 125 persists for more than 48 hours on a specific app, contact LG support to report a Content Store issue.

Frequently Asked Questions

Can I still use the app while it shows Error 125?

Yes — the existing installed version of the app still works even if the update fails. Error 125 only affects the update process, not the currently installed version. You can use the app normally and retry the update later.

Error 125 keeps failing on the same app — what should I do?

Delete the app completely and reinstall it from the LG Content Store. This forces a fresh download of the current version rather than applying an incremental update. If reinstallation also fails, the update package on LG's server may be corrupted — wait 24 hours and try again.

Does Error 125 mean my TV is running out of storage?

It can — if your TV storage is nearly full, app updates cannot be installed. Check Settings → General → About This TV to see how much storage is available. Deleting apps you no longer use or clearing app cache frees up space for updates.
