System Dev Error 11255 Modern Warfare 3

My Xbox series x is updated and I have reinstalled the game four or five times and I’ve even reset the Xbox to out of box state and still didn’t resolve the problem. And for the games support them they said that they have transferred the case to the specialized team and they will investigate it and that there’s no specific time of resolution for the cases. $100 and can’t even play the game. This is the first cod I’ve played and enjoyed since blops3 and now it’s just taking up space in the hard drive.

Did you ever get this figured out? Myself and two other people are having this same error for Xbox.

I was getting kicked every other game due to this error.

Hi. My name is Brilliant, an independent advisor, happy to assist you today.

Here are some possible solutions that may help you resolve the issue:
1. Clear your cache: Clearing your cache can help resolve issues with the game’s files. To do this, go to the game’s settings and select “Clear Cache”.

2. Update your drivers: Ensure that your graphics card drivers are up to date. You can do this by visiting the manufacturer’s website and downloading the latest drivers.

3. Reinstall the game: If the above solutions don’t work, try uninstalling and reinstalling the game. This will replace any broken files and may resolve the issue.

If none of these solutions work, I recommend reaching out to the game’s support team for further assistance. They may be able to help you resolve the issue and get back to playing the game.

I hope this helps.

Mine suddenly started working correctly again. I haven't had the error in two nights.

If yours has not, here are some things to consider:

1.) My son had an extension to my account so he could play on his Xbox. Make sure the Home Xbox in personalization section is correct. Google that. It seemed confusing so I wound up taking him off mine and getting his own account.

2.) I went into my Activision profile on Activision.com and placed a different zip code in the location section to see if I could get a different server.

3.) They may have simply fixed it, particularly after the holiday season ended with the Christmas theme.

Hope yours is working.

I’m getting the same error. It’s been happening since a week after season 1 started. You would think with 1gb internet and having a series x everything should work right.
