"Xbox One E200 Error"に関する回答I am experiencing the same E200 issue. Did the OSU with no luck. Called Xbox and got into a bit of a argument with them about it. There is no reason that mandatory updates or faulty XB1s should be the customer's fault. They are supposed to call back today and continue discussions. Still going to take the stance that this is Microsoft's fault and try to get them to take care of it. Truly David vs. Gilioth here but I'm gonna try it. Wish me luck!
