    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

    Warzone Disk Read Error after newest update in April 2021

    It has completely prevented people from playing and told them to purchase the game again when it is in the disc drive. It's happening to me actually. I contacted activision, and they told me it was an xbox issue, when it very clearly isn't. I contacted xbox, and they confirmed that it is indeed an Activision issue with the bad update.

    I have uninstalled and reinstalled the game more than once, same for data packs, cleared my Mac address, hard started/cycled my xbox, and even reset my xbox. Nothing works. I'm still told to purchase the game. This started after I received the error code dev 6034 in the game yesterday.
