    DEV ERROR 6034


    I downloaded all of the updates for Call of Duty Modern Warfare and every time I try to play I get DEV ERROR 6034. Am on XBOX One. I uninstalled the game and reinstalled all of the updates which took all day, AND IT STILL WILL NOT WORK. **** is going on with this?

    Anyone?

    :)

    I have tried everything to fix the Dev6034 error, deleting packs, deleting everything and wiping my XBOX1 and reloading Modern Warfare, this fixed the problem for two games and then back to the Dev6034 error. This is a Joke, I’m now wondering if this is yet another ploy to get people to replace their XBOX1’s.

    I was going to buy Cold War but I’m not wasting my hard earned until this is fixed, it was all running fine until the recent update.

    As usual now word from the developers!!!!!!!!!

    Has nothing to do with replacing your console. Just got my Xbox one X. Game was playing just fine until the new update. Did everything what everyone is doing and still nothing.

    I am getting dev error 6034 [ww_mp_emporium.ff]

    This is a common issue with all of us. I tried resetting my xbox as support mentioned earlier but still the same. Now I deleted the whole game and waiting for reinstalling to see if it helps

    Hello @ChristianLeBron, I hope everything is going well!

    Thank you for reaching Microsoft Xbox Forum support!

    I would like you to go through the following steps to clear the Mac address and then perform a quick power cycle on your console:

    Settings > Network Settings > Advanced Settings > Alternate Mac Address > Clear it and the console should restart. It would definitely help if you could restart the internet router while the console is restarting.

    After going through the troubleshooting steps mentioned, I invite you to perform a quick power cycle by turning off the console and then unplugging all the cables. After 2 to 3 minutes, re-plug them back again, then restart your console.

    In case the issue still persists, the next step would be to perform a reset on the console. To do so you will need to follow the steps below to perform a reset on the Xbox:

    Settings > System > Console Info > Reset This Xbox > Reset and Keep my Games and Apps.

    Note =>The "Reset and Keep my Games and Apps" option will not cause losing your games, but please be aware that you need to be completely aware of the email address as well as the password of your account before going for it because it will require you to sign in to the account.

    I wish you a lovely day, and I hope this helps you out! All the best!

    Kind Regards

    Stay safe, and happy gaming!
