Some Xbox One users are encountering the 0x8b05000f error code every time they attempt to install a mandatory update on their console. In most cases, the update stops installing at 47%, making their console completely unusable.
When investigating this issue, you should start by ensuring that you’re not dealing with a server issue. If that’s not the case, perform a power cycling to eliminate any problems caused by temporary files.
However, if your console is registered to the Xbox Preview program, you will need to sign in to your Xbox Live account from a Windows 10 console (via Xbox Insider Hub UWP app) and remove your console from the preview program.
In case the problem occurs due to a firmware issue, you have two ways to resolve the problem – You can either install the pending mandatory update manually (you’ll need a flash drive) or you can use the Startup Troubleshooter to reset your console to factory (you’ll end up losing any data it’s currently holding).
Method 1: Investigating the server status
Before you try anything else, it’s important to ensure that the problem is not being facilitated by something that cannot be fixed by the end-user. The update may be failing due to a server issue that is preventing your console from retrieving the files necessary for the firmware update.
To verify if this scenario is true, you will need to check the current status of the Xbox Live services. To do this, visit this link (here) from a mobile or desktop device and see if any service is currently experiencing problems (especially the Xbox Live Core service)
Note: If the status page reveals an issue with some essential Xbox One services, the issue is beyond your control. In this case, all you can do is wait for Microsoft engineers to fix the problem automatically.
If your investigation didn’t reveal any server issues, the problem is likely occurring locally. In this case, one of the fixes below will end up fixing the issue for you.
Method 2: Performing a Power Cycling Procedure
Since you concluded that the problem is only occurring locally, you should start by ensuring that your Xbox One console is not being caused by a temporary file that is interfering with the installation of the new firmware.
When it comes to doing this, the easiest procedure is to perform a power cycling procedure. This is more than a regular console restart since it will end up draining the power capacitors and fix most firmware issues related to corrupted temp files.
To do this, follow the instructions below to do a power cycle on your Xbox One console to fix the 0x8b05000f:
- Ensure that your console is fully turned on (not in hibernation).
- Press the Xbox button on your console and keep it pressed for about 10 seconds (or until you see that the front LED stops flashing)
- Once the front LED stops flashing, release the power button and wait for a full minute before turning your console back on. During this time, it’s recommended that you also physically unplug the power cable from the power outlet to ensure that the power capacitors are completely drained.
- Next, short-press the Xbox button on your console and keep an eye for the initial (longer) startup animation screen. If you see it, take it as confirmation that the power cycling procedure was completed successfully.
- Once your console boots back up, re-attempt the firmware installation and see if you still end up seeing the 0x8b05000f.
In case you still see the same error, move down to the next potential fix below.
Method 3: Removing Xbox Console from Preview program
As it turns out, you can expect to encounter this particular 0x8b05000f error in case your account is currently signed up for the Xbox Preview Program. The vast majority of users that documented this error have confirmed their enrollment in the Xbox Preview program.
If this scenario is applicable and you are indeed enrolled in the Preview program, you will not be able to unlist conventionally since you are no longer able to access your console normally.
However, you can remove your Xbox from the Preview program from a Windows 10 PC by installing the UWP (Universal Windows Platform) application of Xbox Insider Hub. To do this, follow the instructions below:
- Press Windows key + R to open up a Run dialog box. Next, type ‘ms-windows-store://home’ inside the text box and press Enter to open up Microsoft Store.
- Once you’re inside the Microsoft Store, use the search function (top-right corner) to search for ‘Xbox Insider Hub‘. Next, from the list of results, click on Xbox Insider Hub.
- Click on the Get button associated with Xbox Insider Hub and wait for the download to complete.
- Once the download is complete and the application is installed, launch it and sign in with the same Xbox Live account that you are using on your Xbox One console.
- After you manage to sign in successfully, click on the action button (top-left content) and click on Settings.
- From the settings menu, click on the action button (top-left corner) and click on Manage devices from the Settings menu.
- Once you’re inside the Manage Devices settings, remove your Xbox from the preview program and save the modifications.
- Restart your console and your console should now attempt to install a different update since it’s n longer part of the Insider Hub.
In case you’ve followed these instructions to no avail or you weren’t part of the Preview circle, move down to the next potential fix below.
Method 4: Updating the Console’s Firmware manually
If none of the methods below have allowed you to get rid of the 0x8B05000F error while trying to install a mandatory Xbox One update, the only fix left that won’t interfere with your console files is to attempt to install the console’s firmware manually.
This will require you to use a flash drive of at least 10 GB that’s formatted using NTFS. This is the only prerequisite, the rest you can obtain from the Microsoft’s support website. You’ll need to visit the Xbox Support website and download the latest OS firmware version.
If you are prepared to do this, follow the instructions below to update your console’s firmware manually and circumvent the 0x8B05000F error:
- First things first, you’ll need to prepare a flash drive that you will use to perform the offline update. To do this, insert the USB drive into a PC and format it to NTFS. To do this, right-click on the drive in File Explorer and click on Format… from the context menu. Next, set the File System as NTFS and then check the box associated with Quick format before clicking on Start.
- Once you’ve ensured that your flash drive is correctly formatted, visit this link (here) and download the latest version of your Xbox One console firmware.
- Wait until the download is complete, then extract the contents of the archive ($SystemUpdate) on the root folder of the flash drive.
- After the operation is complete, unplug your flash drive safely and move to your console.
- On your Xbox One console, press and hold the Bind + Eject button at the same time, then short press the Xbox button on the console (while continuing to hold the Bind and Eject buttons).
Note: On Xbox One S All-Digital, press the Bond and Xbox button only.
- After you hear to consecutive tones, release the Bind and Eject buttons and wait for the Startup Troubleshooter screen to appear.
- Once it does, insert the flash drive that you previously created at step 1 and wait for the Offline System Update box to become available. Next, select that option with your controller and press X to access it.
- Confirm the operation and wait for the process to complete. Depending on the aspects of your USB flash drive and if you’re using an SSD or HDD on your console, expect this process to last under or well over 10 minutes.
- Once the operation is complete, the console will restart automatically and your system will attempt to boot normally.
In case you don’t have a USB flash drive to complete the operation above, move down to the final fix below.
Method 5: Resetting the Console via Startup Troubleshooter
In case none of the methods below have allowed you to fix the issue, one last resort is to reset your console completely via the Windows Startup troubleshooter. But before you commit to this, keep in mind that this operation will end up deleting your game data, temp files, video content, and anything else you currently have stored on your console.
Note: Save data will not be touched by this operation as long as it’s backed up via Xbox Live.
If you are prepared to go this route and you understand the consequences, start following the instructions below to get started with an offline factory reset on your Xbox One console to fix the 0x8B05000F error:
- Start by turning off your console completely and wait for at least 30 seconds.
- Press and hold the Bind + Eject button at the same time, then short press the Xbox button to start your Xbox One console.
Note: On Xbox One S All-Digital, press the Bond and Xbox button only.
- After you hear the second tone, release the Bind and Eject button and wait for the Xbox Startup Troubleshooter to appear.
- Once you’re inside the Startup Troubleshooter, select the Reset this Xbox with your controller and press the X button to initiate the process.
- At the confirmation prompt, select choose Remove Everything and wait for the operation to complete.
- Once the operation is complete, wait for your console to boot normally and see if the issue is now resolved.
