Xbox Error Code 0x8B0500C8 — What It Means & How to Fix It

What Does This Error Mean?

Xbox error 0x8B0500C8 means a game or app update failed to install correctly. The update may have been downloaded but got corrupted, or the installation was interrupted. The fix usually involves clearing the update and reinstalling it — or in stubborn cases, uninstalling and reinstalling the full game. Your saved game data is stored in the cloud and won't be lost when you reinstall.

Affected Models

Xbox One
Xbox One S
Xbox One X
Xbox Series S
Xbox Series X

Common Causes

Game update download was corrupted by a network interruption mid-download
Insufficient free storage space on the console for the update package
Console was powered off or went into rest mode during the update installation
The game has a pending update that conflicts with the currently installed version
Xbox storage drive has a read/write error causing the update files to fail verification

How to Fix It

Restart the Xbox completely. Hold the Xbox button on the front of the console for 10 seconds until it shuts down. Wait 30 seconds, then power it back on. After restart, go to My Games & Apps > See All > Updates and check if the game's update is listed. Try installing the update again.

A full shutdown clears the update queue and forces the console to re-evaluate which updates are ready to install.
Check available storage space. Go to Settings > System > Storage. If storage is nearly full, delete games you're not currently playing to free up space. Updates need free space to download, unpack, and install — tight storage causes frequent installation failures.

Keep at least 5-10 GB free as a general buffer. Some game updates are 2-5 GB by themselves.
Try pausing and resuming the update. In My Games & Apps > Updates, highlight the stuck update, press the Menu button (three horizontal lines on your controller), and select Pause. Wait 30 seconds, then select Resume. This can restart a stalled download segment.

If the update shows 0% progress and doesn't move for several minutes, it's stalled — pausing and resuming restarts the transfer.
Uninstall and reinstall the affected game. Go to My Games & Apps > See All > Games, highlight the game, press Menu, and select Uninstall All. Then reinstall from your Games & Apps > Full Library. The reinstall will include the latest game version with all current updates already integrated.

Your save data is stored in the cloud (Xbox Live cloud saves). It will still be there after reinstalling — just re-sync when you first launch the game.
If errors persist across multiple games, clear the persistent storage on your console. Go to Settings > Devices & Accessories > Blu-ray > Persistent storage > Clear Persistent Storage. Also try Settings > System > Storage > Clear local saved games (these will re-sync from the cloud). Then restart the console.

Clearing persistent storage removes locally cached disc and update data, forcing a fresh download. Cloud saves are unaffected.

When to Call a Professional

Error 0x8B0500C8 is almost always software-related and doesn't require a repair technician. If reinstalling the game doesn't help and you see this error across multiple games, the console's storage drive may have an issue. In that case, contact Xbox Support at support.xbox.com or 1-800-469-9269 to discuss repair or replacement options under warranty.

Frequently Asked Questions

Will uninstalling a game delete my save files?

No — Xbox automatically saves your game progress to the cloud (Xbox Live cloud saves). Uninstalling a game only removes the game files, not your saved game data. When you reinstall and launch the game, it syncs your saves from the cloud automatically. Make sure you're connected to Xbox Live when you first launch after reinstalling so it can download your cloud saves.

Why do game updates fail so often on Xbox?

Update failures are most commonly caused by storage issues (low space or a slow drive) and network interruptions. Large update files — some are 10-30 GB — are prone to corruption if the download is interrupted. Keeping storage reasonably free (20% or more), using a wired ethernet connection, and letting the console sit quietly during updates significantly reduces failure rates.

Can I play a game while its update is installing?

Yes — Xbox allows you to launch and play a game as soon as the 'Ready to start' portion is downloaded. The rest of the update continues downloading in the background while you play. However, the game version you're playing may be outdated until the update finishes. Online multiplayer features typically require the full current version.
