Several Xbox One users are reporting that they end up seeing the 0x80270300 error code whenever they try to install or update a game on their Xbox One console. This issue is reported to occur with both digital and disc-based games.
Before trying anything else, you should start this troubleshooting guide by ensuring that the game you are trying to start or update manually is not already updating in the background. You can check this by viewing the My games & Apps Queue.
If that’s not the case, you should do a power cycling procedure to clear the power capacitors and ensure that the problem is not being caused by a temporary file. And if you didn’t already try this, reinstall the game conventionally and restart your console at the end of the reinstallation.
However, if the 0x80270300 error code is caused by some type of underlying OS issue, you will need to do a soft reset to refresh every operating system component and eliminate any corrupted instances.
Checking if the game is Currently Updating
As it turns out, one of the most common scenarios that will ultimately trigger the 0x80270300 error is when the user tries to launch a game that is being updated in the background. In most cases, your console should notify of this, but you can also expect to see this ambiguous error message.
To verify if this potential scenario is true, you will need to check your current My games & Apps Queue to see if the game you want to launch is getting an update.
To do this, follow the instructions below:
- Press the Xbox button on your controller to bring up the guide menu.
- From the guide menu, select My Apps & Games > Games.
- Next, select the Queue category and see if the game triggering the 0x80270300 error is currently being updated.
In case your investigation has revealed that the game currently causing the error is not being updated, move down to the next potential fix below.
Power Cycling your Console
Another potential culprit that might end up causing this issue is corruption located inside the temp folder that your console maintains. This might end up interfering with the installation of new games or even with the launch of new games.
To resolve this issue, the easiest procedure is to perform a power cycle. This will clear any temp data and drain the power capacitors (also good for resolving the majority of firmware-related issues).
Follow the instructions below to do a power cycle on your Xbox One console to fix the 0x80270300 error:
- Ensure that your console is fully booted in idle mode (not installing everything and not in hibernation mode).
- On your console, press the Xbox button and keep it pressed for about 10 seconds (or until you see that the front LEDs stop flashing)
- After your console no longer shows signs of life, release the power button and wait for at least one minute before powering ON again. While you wait, also disconnect the power cable from the rear to make sure that the power capacitors are completely drained.
- Next, turn your console back on by pressing the power button on your console once again. During this startup, keep an eye out for the longer startup animation – if you see it, it means that the operation was succesfull.
- Once the startup sequence is finished, launch the same game that was previously causing the error and see if the issue is now resolved.
In case the same problem is still occurring, move down to the next potential fix below.
Reinstalling the Game
If the two potential fixes above didn’t work for you, your problem is most likely caused by a corrupted game file that ends up making the game unplayable. Several affected users have confirmed that in their case, the problem was fixed and they were able to start and update the game after they reinstalled the game conventionally.
To do this, follow the instructions below to reinstall any Xbox One game to fix the 0x80270300 error code:
- Press the Xbox button on your controller to open up the guide menu, then navigate to the Games & apps menu.
- Next, from the Game & apps menu, navigate to the game that you’re trying to uninstall, press the start button and choose Manage game.
- Next, use the Manage menu to navigate to the right pane and click on Uninstall all to ensure that every add-in or update is also removed.
- Confirm the installation by choosing Uninstall all, then wait for the process to complete.
- Once the operation is complete, return to the Manage menu on the left-hand side section and go to the Ready to install section. Next, go to the right pane and select Install all. This procedure will end up re-installing the base game plus any game addons that you are currently entitled to.
- After the game is successfully reinstalled, restart your console and launch the game at the next startup to see if you’re still seeing the same error message.
In case you are still greeted by the same 0x80270300 error code when trying to launch, install or update a game on your Xbox One console, move down to the next potential fix below.
Soft Resetting your Xbox One Console
If none of the methods above have worked for you, likely, you’re dealing with some kind of corruption originating for your console OS files. To deal with a problem of this kind, you will need to reset every file belonging to your OS – which will also end up deleting corrupted data.
Note: If you want to avoid total data loss, you can make it so that only OS files are touched by this procedure – allowing you to keep your games, applications and other types of media that you’re currently storing.
Several affected users have confirmed that this operation was the only thing that allowed them to install, update, and start games without encountering the 0x80270300 error code.
To enforce this fix, follow the instructions below:
- Press the Xbox button (on your controller) to open up the guide menu. From there, navigate to System > Settings > System Console Info.
- From the Console Info menu, choose Reset console from the list of available options.
- After you’re inside the Reset console menu, select the Reset and keep my games & apps.
Note: You can also select Reset and remove everything if you don’t have anything of importance on your Xbox Storage that you are afraid of losing.
- Start the procedure and wait for the operation to complete. At the end of it, launch the game that was previously showing the 0x80270300 error code to see if the problem is now resolved.
