Symptoms
- Progress bar stops moving during an update
- TV shows an update error message
- TV restarts mid-update and won't finish
- Update has been 'installing' for over 30 minutes
Likely causes
- CommonWeak or interrupted internet connection during downloadUpdates can be tens or hundreds of megabytes and will stall if the connection drops mid-download.
- CommonUpdate process needs more time than expectedSome updates genuinely take 20–40 minutes and only look stuck.
- PossiblePower interruption during installationLosing power while writing new firmware can leave the update incomplete.
- PossibleUpdate server issue on the manufacturer's sideRarely, the update file itself can be temporarily unavailable or corrupted at the source.
What to do
- Leave the TV alone and powered on for at least 30–45 minutes before assuming it's truly stuck.
- Make sure the TV stays connected to power and Wi-Fi throughout the entire process; don't unplug it during an active update.
- If it's been over an hour with no progress and no error message, try unplugging for 60 seconds and powering back on.
- Check your internet connection strength near the TV and consider moving closer to the router or using Ethernet.
- Look up your model number plus 'firmware update stuck' on the manufacturer's official support site for known issues.
- If the TV won't boot normally after a failed update, check the manufacturer's site for a manual firmware recovery procedure, often done via USB.
- Contact the manufacturer's support line if the TV is unresponsive after a failed update.
Tools and parts
- USB drive (if manual recovery is needed)
When to call a pro
If a manual USB firmware recovery doesn't bring the TV back, a technician or the manufacturer's authorized service center can attempt a deeper recovery.
